Taking a complexity perspective.
The first paper in this series 17 outlines aspects of complexity associated with complex interventions and health systems that can potentially be explored by different types of evidence, including synthesis of quantitative and qualitative evidence. Petticrew et al 17 distinguish between a complex interventions perspective and a complex systems perspective. A complex interventions perspective defines interventions as having “implicit conceptual boundaries, representing a flexible, but common set of practices, often linked by an explicit or implicit theory about how they work”. A complex systems perspective differs in that “ complexity arises from the relationships and interactions between a system’s agents (eg, people, or groups that interact with each other and their environment), and its context. A system perspective conceives the intervention as being part of the system, and emphasises changes and interconnections within the system itself”. Aspects of complexity associated with implementation of complex interventions in health systems that could potentially be addressed with a synthesis of quantitative and qualitative evidence are summarised in table 2 . Another paper in the series outlines criteria used in a new evidence to decision framework for making decisions about complex interventions implemented in complex systems, against which the need for quantitative and qualitative evidence can be mapped. 16 A further paper 18 that explores how context is dealt with in guidelines and reviews taking a complexity perspective also recommends using both quantitative and qualitative evidence to better understand context as a source of complexity. Mixed-method syntheses of quantitative and qualitative evidence can also help with understanding of whether there has been theory failure and or implementation failure. The Cochrane Qualitative and Implementation Methods Group provide additional guidance on exploring implementation and theory failure that can be adapted to address aspects of complexity of complex interventions when implemented in health systems. 19
Health-system complexity-related questions that a synthesis of quantitative and qualitative evidence could address (derived from Petticrew et al 17 )
Aspect of complexity of interest | Examples of potential research question(s) that a synthesis of qualitative and quantitative evidence could address | Types of studies or data that could contribute to a review of qualitative and quantitative evidence |
What ‘is’ the system? How can it be described? | What are the main influences on the health problem? How are they created and maintained? How do these influences interconnect? Where might one intervene in the system? | Quantitative: previous systematic reviews of the causes of the problem); epidemiological studies (eg, cohort studies examining risk factors of obesity); network analysis studies showing the nature of social and other systems Qualitative data: theoretical papers; policy documents |
Interactions of interventions with context and adaptation | Qualitative: (1) eg, qualitative studies; case studies Quantitative: (2) trials or other effectiveness studies from different contexts; multicentre trials, with stratified reporting of findings; other quantitative studies that provide evidence of moderating effects of context | |
System adaptivity (how does the system change?) | (How) does the system change when the intervention is introduced? Which aspects of the system are affected? Does this potentiate or dampen its effects? | Quantitative: longitudinal data; possibly historical data; effectiveness studies providing evidence of differential effects across different contexts; system modelling (eg, agent-based modelling) Qualitative: qualitative studies; case studies |
Emergent properties | What are the effects (anticipated and unanticipated) which follow from this system change? | Quantitative: prospective quantitative evaluations; retrospective studies (eg, case–control studies, surveys) may also help identify less common effects; dose–response evaluations of impacts at aggregate level in individual studies or across studies included with systematic reviews (see suggested examples) Qualitative: qualitative studies |
Positive (reinforcing) and negative (balancing) feedback loops | What explains change in the effectiveness of the intervention over time? Are the effects of an intervention are damped/suppressed by other aspects of the system (eg, contextual influences?) | Quantitative: studies of moderators of effectiveness; long-term longitudinal studies Qualitative: studies of factors that enable or inhibit implementation of interventions |
Multiple (health and non-health) outcomes | What changes in processes and outcomes follow the introduction of this system change? At what levels in the system are they experienced? | Quantitative: studies tracking change in the system over time Qualitative: studies exploring effects of the change in individuals, families, communities (including equity considerations and factors that affect engagement and participation in change) |
It may not be apparent which aspects of complexity or which elements of the complex intervention or health system can be explored in a guideline process, or whether combining qualitative and quantitative evidence in a mixed-method synthesis will be useful, until the available evidence is scoped and mapped. 17 20 A more extensive lead in phase is typically required to scope the available evidence, engage with stakeholders and to refine the review parameters and questions that can then be mapped against potential review designs and methods of synthesis. 20 At the scoping stage, it is also common to decide on a theoretical perspective 21 or undertake further work to refine a theoretical perspective. 22 This is also the stage to begin articulating the programme theory of the complex intervention that may be further developed to refine an understanding of complexity and show how the intervention is implemented in and impacts on the wider health system. 17 23 24 In practice, this process can be lengthy, iterative and fluid with multiple revisions to the review scope, often developing and adapting a logic model 17 as the available evidence becomes known and the potential to incorporate different types of review designs and syntheses of quantitative and qualitative evidence becomes better understood. 25 Further questions, propositions or hypotheses may emerge as the reviews progress and therefore the protocols generally need to be developed iteratively over time rather than a priori.
Following a scoping exercise and definition of key questions, the next step in the guideline development process is to identify existing or commission new systematic reviews to locate and summarise the best available evidence in relation to each question. For example, case study 2, ‘Optimising health worker roles for maternal and newborn health through task shifting’, included quantitative reviews that did and did not take an additional complexity perspective, and qualitative evidence syntheses that were able to explain how specific elements of complexity impacted on intervention outcomes within the wider health system. Further understanding of health system complexity was facilitated through the conduct of additional country-level case studies that contributed to an overall understanding of what worked and what happened when lay health worker interventions were implemented. See table 1 online supplementary file 2 .
There are a few existing examples, which we draw on in this paper, but integrating quantitative and qualitative evidence in a mixed-method synthesis is relatively uncommon in a guideline process. Box 2 includes a set of key questions that guideline developers and review authors contemplating combining quantitative and qualitative evidence in mixed-methods design might ask. Subsequent sections provide more information and signposting to further reading to help address these key questions.

Petticrew et al 17 define the different aspects of complexity and examples of complexity-related questions that can potentially be explored in guidelines and systematic reviews taking a complexity perspective. Relevant aspects of complexity outlined by Petticrew et al 17 are summarised in table 2 below, together with the corresponding questions that could be addressed in a synthesis combining qualitative and quantitative evidence. Importantly, the aspects of complexity and their associated concepts of interest have however yet to be translated fully in primary health research or systematic reviews. There are few known examples where selected complexity concepts have been used to analyse or reanalyse a primary intervention study. Most notable is Chandler et al 26 who specifically set out to identify and translate a set of relevant complexity theory concepts for application in health systems research. Chandler then reanalysed a trial process evaluation using selected complexity theory concepts to better understand the complex causal pathway in the health system that explains some aspects of complexity in table 2 .
Rehfeuss et al 16 also recommends upfront consideration of the WHO-INTEGRATE evidence to decision criteria when planning a guideline and formulating questions. The criteria reflect WHO norms and values and take account of a complexity perspective. The framework can be used by guideline development groups as a menu to decide which criteria to prioritise, and which study types and synthesis methods can be used to collect evidence for each criterion. Many of the criteria and their related questions can be addressed using a synthesis of quantitative and qualitative evidence: the balance of benefits and harms, human rights and sociocultural acceptability, health equity, societal implications and feasibility (see table 3 ). Similar aspects in the DECIDE framework 15 could also be addressed using synthesis of qualitative and quantitative evidence.
Integrate evidence to decision framework criteria, example questions and types of studies to potentially address these questions (derived from Rehfeuss et al 16 )
Domains of the WHO-INTEGRATE EtD framework | Examples of potential research question(s) that a synthesis of qualitative and/or quantitative evidence could address | Types of studies that could contribute to a review of qualitative and quantitative evidence |
Balance of benefits and harms | To what extent do patients/beneficiaries different health outcomes? | Qualitative: studies of views and experiences Quantitative: Questionnaire surveys |
Human rights and sociocultural acceptability | Is the intervention to patients/beneficiaries as well as to those implementing it?

Societal implications | What is the of the intervention: are there features of the intervention that increase or reduce stigma and that lead to social consequences? Does the intervention enhance or limit social goals, such as education, social cohesion and the attainment of various human rights beyond health?

Questions can serve as an ‘anchor’ by articulating the specific aspects of complexity to be explored (eg, Is successful implementation of the intervention context dependent?). 27 Anchor questions such as “How does intervention x impact on socioeconomic inequalities in health behaviour/outcome x” are the kind of health system question that requires a synthesis of both quantitative and qualitative evidence and hence a mixed-method synthesis. Quantitative evidence can quantify the difference in effect, but does not answer the question of how . The ‘how’ question can be partly answered with quantitative and qualitative evidence. For example, quantitative evidence may reveal where socioeconomic status and inequality emerges in the health system (an emergent property) by exploring questions such as “ Does patterning emerge during uptake because fewer people from certain groups come into contact with an intervention in the first place? ” or “ are people from certain backgrounds more likely to drop out, or to maintain effects beyond an intervention differently? ” Qualitative evidence may help understand the reasons behind all of these mechanisms. Alternatively, questions can act as ‘compasses’ where a question sets out a starting point from which to explore further and to potentially ask further questions or develop propositions or hypotheses to explore through a complexity perspective (eg, What factors enhance or hinder implementation?). 27 Other papers in this series provide further guidance on developing questions for qualitative evidence syntheses and guidance on question formulation. 14 28
For anchor and compass questions, additional application of a theory (eg, complexity theory) can help focus evidence synthesis and presentation to explore and explain complexity issues. 17 21 Development of a review specific logic model(s) can help to further refine an initial understanding of any complexity-related issues of interest associated with a specific intervention, and if appropriate the health system or section of the health system within which to contextualise the review question and analyse data. 17 23–25 Specific tools are available to help clarify context and complex interventions. 17 18
If a complexity perspective, and certain criteria within evidence to decision frameworks, is deemed relevant and desirable by guideline developers, it is only possible to pursue a complexity perspective if the evidence is available. Careful scoping using knowledge maps or scoping reviews will help inform development of questions that are answerable with available evidence. 20 If evidence of effect is not available, then a different approach to develop questions leading to a more general narrative understanding of what happened when complex interventions were implemented in a health system will be required (such as in case study 3—risk communication guideline). This should not mean that the original questions developed for which no evidence was found when scoping the literature were not important. An important function of creating a knowledge map is also to identify gaps to inform a future research agenda.
Table 2 and online supplementary files 1–3 outline examples of questions in the three case studies, which were all ‘COMPASS’ questions for the qualitative evidence syntheses.
The shift towards integration of qualitative and quantitative evidence in primary research has, in recent years, begun to be mirrored within research synthesis. 29–31 The natural extension to undertaking quantitative or qualitative reviews has been the development of methods for integrating qualitative and quantitative evidence within reviews, and within the guideline process using evidence to decision-frameworks. Advocating the integration of quantitative and qualitative evidence assumes a complementarity between research methodologies, and a need for both types of evidence to inform policy and practice. Below, we briefly outline the current designs for integrating qualitative and quantitative evidence within a mixed-method review or synthesis.
One of the early approaches to integrating qualitative and quantitative evidence detailed by Sandelowski et al 32 advocated three basic review designs: segregated, integrated and contingent designs, which have been further developed by Heyvaert et al 33 ( box 3 ).
Segregated design.
Conventional separate distinction between quantitative and qualitative approaches based on the assumption they are different entities and should be treated separately; can be distinguished from each other; their findings warrant separate analyses and syntheses. Ultimately, the separate synthesis results can themselves be synthesised.
The methodological differences between qualitative and quantitative studies are minimised as both are viewed as producing findings that can be readily synthesised into one another because they address the same research purposed and questions. Transformation involves either turning qualitative data into quantitative (quantitising) or quantitative findings are turned into qualitative (qualitising) to facilitate their integration.
Takes a cyclical approach to synthesis, with the findings from one synthesis informing the focus of the next synthesis, until all the research objectives have been addressed. Studies are not necessarily grouped and categorised as qualitative or quantitative.
A recent review of more than 400 systematic reviews 34 combining quantitative and qualitative evidence identified two main synthesis designs—convergent and sequential. In a convergent design, qualitative and quantitative evidence is collated and analysed in a parallel or complementary manner, whereas in a sequential synthesis, the collation and analysis of quantitative and qualitative evidence takes place in a sequence with one synthesis informing the other ( box 4 ). 6 These designs can be seen to build on the work of Sandelowski et al , 32 35 particularly in relation to the transformation of data from qualitative to quantitative (and vice versa) and the sequential synthesis design, with a cyclical approach to reviewing that evokes Sandelowski’s contingent design.
Convergent synthesis design.
Qualitative and quantitative research is collected and analysed at the same time in a parallel or complementary manner. Integration can occur at three points:
a. Data-based convergent synthesis design
All included studies are analysed using the same methods and results presented together. As only one synthesis method is used, data transformation occurs (qualitised or quantised). Usually addressed one review question.
b. Results-based convergent synthesis design
Qualitative and quantitative data are analysed and presented separately but integrated using a further synthesis method; eg, narratively, tables, matrices or reanalysing evidence. The results of both syntheses are combined in a third synthesis. Usually addresses an overall review question with subquestions.
c. Parallel-results convergent synthesis design
Qualitative and quantitative data are analysed and presented separately with integration occurring in the interpretation of results in the discussion section. Usually addresses two or more complimentary review questions.
A two-phase approach, data collection and analysis of one type of evidence (eg, qualitative), occurs after and is informed by the collection and analysis of the other type (eg, quantitative). Usually addresses an overall question with subquestions with both syntheses complementing each other.
The three case studies ( table 1 , online supplementary files 1–3 ) illustrate the diverse combination of review designs and synthesis methods that were considered the most appropriate for specific guidelines.
In this section, we draw on examples where specific review designs and methods have been or can be used to explore selected aspects of complexity in guidelines or systematic reviews. We also identify other review methods that could potentially be used to explore aspects of complexity. Of particular note, we could not find any specific examples of systematic methods to synthesise highly diverse research designs as advocated by Petticrew et al 17 and summarised in tables 2 and 3 . For example, we could not find examples of methods to synthesise qualitative studies, case studies, quantitative longitudinal data, possibly historical data, effectiveness studies providing evidence of differential effects across different contexts, and system modelling studies (eg, agent-based modelling) to explore system adaptivity.
There are different ways that quantitative and qualitative evidence can be integrated into a review and then into a guideline development process. In practice, some methods enable integration of different types of evidence in a single synthesis, while in other methods, the single systematic review may include a series of stand-alone reviews or syntheses that are then combined in a cross-study synthesis. Table 1 provides an overview of the characteristics of different review designs and methods and guidance on their applicability for a guideline process. Designs and methods that have already been used in WHO guideline development are described in part A of the table. Part B outlines a design and method that can be used in a guideline process, and part C covers those that have the potential to integrate quantitative, qualitative and mixed-method evidence in a single review design (such as meta-narrative reviews and Bayesian syntheses), but their application in a guideline context has yet to be demonstrated.
Depending on the review design (see boxes 3 and 4 ), integration can potentially take place at a review team and design level, and more commonly at several key points of the review or guideline process. The following sections outline potential points of integration and associated practical considerations when integrating quantitative and qualitative evidence in guideline development.
In a guideline process, it is common for syntheses of quantitative and qualitative evidence to be done separately by different teams and then to integrate the evidence. A practical consideration relates to the organisation, composition and expertise of the review teams and ways of working. If the quantitative and qualitative reviews are being conducted separately and then brought together by the same team members, who are equally comfortable operating within both paradigms, then a consistent approach across both paradigms becomes possible. If, however, a team is being split between the quantitative and qualitative reviews, then the strengths of specialisation can be harnessed, for example, in quality assessment or synthesis. Optimally, at least one, if not more, of the team members should be involved in both quantitative and qualitative reviews to offer the possibility of making connexions throughout the review and not simply at re-agreed junctures. This mirrors O’Cathain’s conclusion that mixed-methods primary research tends to work only when there is a principal investigator who values and is able to oversee integration. 9 10 While the above decisions have been articulated in the context of two types of evidence, variously quantitative and qualitative, they equally apply when considering how to handle studies reporting a mixed-method study design, where data are usually disaggregated into quantitative and qualitative for the purposes of synthesis (see case study 3—risk communication in humanitarian disasters).
Clearly specified key question(s), derived from a scoping or consultation exercise, will make it clear if quantitative and qualitative evidence is required in a guideline development process and which aspects will be addressed by which types of evidence. For the remaining stages of the process, as documented below, a review team faces challenges as to whether to handle each type of evidence separately, regardless of whether sequentially or in parallel, with a view to joining the two products on completion or to attempt integration throughout the review process. In each case, the underlying choice is of efficiencies and potential comparability vs sensitivity to the underlying paradigm.
Once key questions are clearly defined, the guideline development group typically needs to consider whether to conduct a single sensitive search to address all potential subtopics (lumping) or whether to conduct specific searches for each subtopic (splitting). 36 A related consideration is whether to search separately for qualitative, quantitative and mixed-method evidence ‘streams’ or whether to conduct a single search and then identify specific study types at the subsequent sifting stage. These two considerations often mean a trade-off between a single search process involving very large numbers of records or a more protracted search process retrieving smaller numbers of records. Both approaches have advantages and choice may depend on the respective availability of resources for searching and sifting.
Closely related to decisions around searching are considerations relating to screening and selecting studies for inclusion in a systematic review. An important consideration here is whether the review team will screen records for all review types, regardless of their subsequent involvement (‘altruistic sifting’), or specialise in screening for the study type with which they are most familiar. The risk of missing relevant reports might be minimised by whole team screening for empirical reports in the first instance and then coding them for a specific quantitative, qualitative or mixed-methods report at a subsequent stage.
Within a guideline process, review teams may be more limited in their choice of instruments to assess methodological limitations of primary studies as there are mandatory requirements to use the Cochrane risk of bias tool 37 to feed into Grading of Recommendations Assessment, Development and Evaluation (GRADE) 38 or to select from a small pool of qualitative appraisal instruments in order to apply GRADE; Confidence in the Evidence from Reviews of Qualitative Research (GRADE-CERQual) 39 to assess the overall certainty or confidence in findings. The Cochrane Qualitative and Implementation Methods Group has recently issued guidance on the selection of appraisal instruments and core assessment criteria. 40 The Mixed-Methods Appraisal Tool, which is currently undergoing further development, offers a single quality assessment instrument for quantitative, qualitative and mixed-methods studies. 41 Other options include using corresponding instruments from within the same ‘stable’, for example, using different Critical Appraisal Skills Programme instruments. 42 While using instruments developed by the same team or organisation may achieve a degree of epistemological consonance, benefits may come more from consistency of approach and reporting rather than from a shared view of quality. Alternatively, a more paradigm-sensitive approach would involve selecting the best instrument for each respective review while deferring challenges from later heterogeneity of reporting.
The way in which data and evidence are extracted from primary research studies for review will be influenced by the type of integrated synthesis being undertaken and the review purpose. Initially, decisions need to be made regarding the nature and type of data and evidence that are to be extracted from the included studies. Method-specific reporting guidelines 43 44 provide a good template as to what quantitative and qualitative data it is potentially possible to extract from different types of method-specific study reports, although in practice reporting quality varies. Online supplementary file 5 provides a hypothetical example of the different types of studies from which quantitative and qualitative evidence could potentially be extracted for synthesis.
The decisions around what data or evidence to extract will be guided by how ‘integrated’ the mixed-method review will be. For those reviews where the quantitative and qualitative findings of studies are synthesised separately and integrated at the point of findings (eg, segregated or contingent approaches or sequential synthesis design), separate data extraction approaches will likely be used.
Where integration occurs during the process of the review (eg, integrated approach or convergent synthesis design), an integrated approach to data extraction may be considered, depending on the purpose of the review. This may involve the use of a data extraction framework, the choice of which needs to be congruent with the approach to synthesis chosen for the review. 40 45 The integrative or theoretical framework may be decided on a priori if a pre-developed theoretical or conceptual framework is available in the literature. 27 The development of a framework may alternatively arise from the reading of the included studies, in relation to the purpose of the review, early in the process. The Cochrane Qualitative and Implementation Methods Group provide further guidance on extraction of qualitative data, including use of software. 40
Relatively few synthesis methods start off being integrated from the beginning, and these methods have generally been subject to less testing and evaluation particularly in a guideline context (see table 1 ). A review design that started off being integrated from the beginning may be suitable for some guideline contexts (such as in case study 3—risk communication in humanitarian disasters—where there was little evidence of effect), but in general if there are sufficient trials then a separate systematic review and meta-analysis will be required for a guideline. Other papers in this series offer guidance on methods for synthesising quantitative 46 and qualitative evidence 14 in reviews that take a complexity perspective. Further guidance on integrating quantitative and qualitative evidence in a systematic review is provided by the Cochrane Qualitative and Implementation Methods Group. 19 27 29 40 47
It is highly likely (unless there are well-designed process evaluations) that the primary studies may not themselves seek to address the complexity-related questions required for a guideline process. In which case, review authors will need to configure the available evidence and transform the evidence through the synthesis process to produce explanations, propositions and hypotheses (ie, findings) that were not obvious at primary study level. It is important that guideline commissioners, developers and review authors are aware that specific methods are intended to produce a type of finding with a specific purpose (such as developing new theory in the case of meta-ethnography). 48 Case study 1 (antenatal care guideline) provides an example of how a meta-ethnography was used to develop a new theory as an end product, 48 49 as well as framework synthesis which produced descriptive and explanatory findings that were more easily incorporated into the guideline process. 27 The definitions ( box 5 ) may be helpful when defining the different types of findings.
Descriptive findings —qualitative evidence-driven translated descriptive themes that do not move beyond the primary studies.
Explanatory findings —may either be at a descriptive or theoretical level. At the descriptive level, qualitative evidence is used to explain phenomena observed in quantitative results, such as why implementation failed in specific circumstances. At the theoretical level, the transformed and interpreted findings that go beyond the primary studies can be used to explain the descriptive findings. The latter description is generally the accepted definition in the wider qualitative community.
Hypothetical or theoretical finding —qualitative evidence-driven transformed themes (or lines of argument) that go beyond the primary studies. Although similar, Thomas and Harden 56 make a distinction in the purposes between two types of theoretical findings: analytical themes and the product of meta-ethnographies, third-order interpretations. 48
Analytical themes are a product of interrogating descriptive themes by placing the synthesis within an external theoretical framework (such as the review question and subquestions) and are considered more appropriate when a specific review question is being addressed (eg, in a guideline or to inform policy). 56
Third-order interpretations come from translating studies into one another while preserving the original context and are more appropriate when a body of literature is being explored in and of itself with broader or emergent review questions. 48
A critical element of guideline development is the formulation of recommendations by the Guideline Development Group, and EtD frameworks help to facilitate this process. 16 The EtD framework can also be used as a mechanism to integrate and display quantitative and qualitative evidence and findings mapped against the EtD framework domains with hyperlinks to more detailed evidence summaries from contributing reviews (see table 1 ). It is commonly the EtD framework that enables the findings of the separate quantitative and qualitative reviews to be brought together in a guideline process. Specific challenges when populating the DECIDE evidence to decision framework 15 were noted in case study 3 (risk communication in humanitarian disasters) as there was an absence of intervention effect data and the interventions to communicate public health risks were context specific and varied. These problems would not, however, have been addressed by substitution of the DECIDE framework with the new INTEGRATE 16 evidence to decision framework. A d ifferent type of EtD framework needs to be developed for reviews that do not include sufficient evidence of intervention effect.
Mixed-method review and synthesis methods are generally the least developed of all systematic review methods. It is acknowledged that methods for combining quantitative and qualitative evidence are generally poorly articulated. 29 50 There are however some fairly well-established methods for using qualitative evidence to explore aspects of complexity (such as contextual, implementation and outcome complexity), which can be combined with evidence of effect (see sections A and B of table 1 ). 14 There are good examples of systematic reviews that use these methods to combine quantitative and qualitative evidence, and examples of guideline recommendations that were informed by evidence from both quantitative and qualitative reviews (eg, case studies 1–3). With the exception of case study 3 (risk communication), the quantitative and qualitative reviews for these specific guidelines have been conducted separately, and the findings subsequently brought together in an EtD framework to inform recommendations.
Other mixed-method review designs have potential to contribute to understanding of complex interventions and to explore aspects of wider health systems complexity but have not been sufficiently developed and tested for this specific purpose, or used in a guideline process (section C of table 1 ). Some methods such as meta-narrative reviews also explore different questions to those usually asked in a guideline process. Methods for processing (eg, quality appraisal) and synthesising the highly diverse evidence suggested in tables 2 and 3 that are required to explore specific aspects of health systems complexity (such as system adaptivity) and to populate some sections of the INTEGRATE EtD framework remain underdeveloped or in need of development.
In addition to the required methodological development mentioned above, there is no GRADE approach 38 for assessing confidence in findings developed from combined quantitative and qualitative evidence. Another paper in this series outlines how to deal with complexity and grading different types of quantitative evidence, 51 and the GRADE CERQual approach for qualitative findings is described elsewhere, 39 but both these approaches are applied to method-specific and not mixed-method findings. An unofficial adaptation of GRADE was used in the risk communication guideline that reported mixed-method findings. Nor is there a reporting guideline for mixed-method reviews, 47 and for now reports will need to conform to the relevant reporting requirements of the respective method-specific guideline. There is a need to further adapt and test DECIDE, 15 WHO-INTEGRATE 16 and other types of evidence to decision frameworks to accommodate evidence from mixed-method syntheses which do not set out to determine the statistical effects of interventions and in circumstances where there are no trials.
When conducting quantitative and qualitative reviews that will subsequently be combined, there are specific considerations for managing and integrating the different types of evidence throughout the review process. We have summarised different options for combining qualitative and quantitative evidence in mixed-method syntheses that guideline developers and systematic reviewers can choose from, as well as outlining the opportunities to integrate evidence at different stages of the review and guideline development process.
Review commissioners, authors and guideline developers generally have less experience of combining qualitative and evidence in mixed-methods reviews. In particular, there is a relatively small group of reviewers who are skilled at undertaking fully integrated mixed-method reviews. Commissioning additional qualitative and mixed-method reviews creates an additional cost. Large complex mixed-method reviews generally take more time to complete. Careful consideration needs to be given as to which guidelines would benefit most from additional qualitative and mixed-method syntheses. More training is required to develop capacity and there is a need to develop processes for preparing the guideline panel to consider and use mixed-method evidence in their decision-making.
This paper has presented how qualitative and quantitative evidence, combined in mixed-method reviews, can help understand aspects of complex interventions and the systems within which they are implemented. There are further opportunities to use these methods, and to further develop the methods, to look more widely at additional aspects of complexity. There is a range of review designs and synthesis methods to choose from depending on the question being asked or the questions that may emerge during the conduct of the synthesis. Additional methods need to be developed (or existing methods further adapted) in order to synthesise the full range of diverse evidence that is desirable to explore the complexity-related questions when complex interventions are implemented into health systems. We encourage review commissioners and authors, and guideline developers to consider using mixed-methods reviews and synthesis in guidelines and to report on their usefulness in the guideline development process.

Objectives Creating health-supportive environments is one of the key strategies for health promotion. The WHO launched the Healthy Cities Initiative which has inspired other international organisations to develop settings-based health initiatives, such as the Child Friendly Cities by UNICEF. Our study aimed to explore the perspectives and experiences of experts, city council staff and mothers of children under 6 years of age in the city of Tehran, Iran regarding child health-friendly neighbourhoods for children of this age group.
Design The purpose of this qualitative research was to investigate the viewpoints and experiences of mothers of children under 6 years old as well as professionals. Data were collected from January to July 2022 through semistructured, indepth interviews using an interview guide. Data were analysed using the directed content analysis method with MAXQDA V.2020 software.
Setting The study was conducted in Tehran, Iran.
Participants Participants were selected from three main groups: experts, mothers and city council staff. Participants were invited to take part using variation purposive sampling techniques.
Results Data analysis led to a definition of the concept of child health-friendly neighbourhoods for children under 6 years old, with 6 dimensions, 21 subdimensions and 80 characteristics. The six dimensions included the provision of neighbourhood green space, cultural centres, health centres, access to services, transport and security. The characteristics we identified had similarities and differences with UNICEF’s Child Friendly Cities.
Conclusion The concept of a child health-friendly neighbourhood for children under 6 years old is the result of a health-centred approach to a child-friendly city that provides a deeper understanding of the needs and services required to start a healthy life. This could contribute to further dialogue, research and actions to make all neighbourhoods a health-supportive environment as recommended by the Ottawa Charter for Health Promotion.

The main strength of this study is that the needs of children were identified and investigated from the perspectives of experts, city council staff and mothers of children under 6 years of age.
To the best of our knowledge, this study is the first to examine the characteristics of a child health-friendly neighbourhood and the needs of young children in the Iranian context.
One potential limitation is that fathers and children were not included in the study.
Based on the conditions in each neighbourhood, the needs of children in each neighbourhood may be different.
Acknowledging the role of social determinants of health and the birth of the field of health promotion in 1986 have created an important shift in understanding and thus strategies for protecting and promoting population health. 1 Based on the Ottawa Charter for Health Promotion, the creation of ‘health supportive environments’ is considered the third of the five main strategies for health promotion, before the development of individual health skills and provision of healthcare services. 2 Since then, the WHO has followed a health-promoting setting approach by launching its Healthy Cities Initiative in 1986. 2 3 Cities are an important place especially for children. It is estimated that by 2030 about 60% of urban residents will be under the age of 18. 4 For this reason, several initiatives were proposed to transform cities to healthier settings, such as the Child Friendly Cities initiated by UNICEF 4 5 and London’s 2017 Living Cities project, with a view to creating child-friendly cities and using an urban design approach that focuses on children and their health across the lifespan. 6 7 There is an increasing focus on taking children’s needs into account when designing cities and developing urban programmes and services more comprehensively. For example, the international initiative ‘City 95’ looked at cities from the perspectives of 3-year-old children with an average height of 95 cm. 8 9
A child-friendly city is one that prioritises the interests of children and their fundamental rights, including health, education and cultural opportunities, as well as safety and security, green spaces and play places. It refers to a city where children have a healthy start and have equal opportunities in life regardless of their ethnicity, religion, income, gender or abilities. 10 11 UNICEF proposed seven domains to explain the main indicators of a child-friendly city, namely playgrounds and green spaces, education and culture, health and children’s health, access to services, participation in decision-making, safety and ease of transport, and children’s security. 12
Although a child in the child-friendly city concept refers to an individual in the 0–18 years old age group, 13 most programmes and studies on child-friendly cities have focused on children 6–18 years old, 14–16 ignoring the needs of those under 6 years of age. Furthermore, the cities or neighbourhoods have mostly been studied from the perspectives of children’s social rights, focusing on urban planning, social rights areas 17–20 and the livability of the city or neighbourhoods for children. 21 There was limited consideration of a health-centred approach to developing our understanding of children’s needs. 22 Finally, the lack of specific indicators to measure the state of cities and neighbourhoods for children hinders the comprehensive implementation of a child-friendly city concept. 23 24 As context is a crucial factor in the implementation of a child-friendly city approach, the standards or criteria can vary, bearing in mind that they should reflect the conditions of the local context, institutions and organisations in each country. 22 Because they are among the most vulnerable, younger children may have demands that are different from older groups when it comes to neighbourhood features. 25 Besides, there is a limited number of studies that investigated the needs of children from the perspectives of mothers and relevant experts. Therefore, to fill this gap, especially within the Iranian context, a comprehensive mixed methods study was designed to develop a national Child Health-Friendly Neighborhood for Under 6 Years of Age Children (U6CHFN) and use it to explore the needs of young children under 6 years of age in Tehran. This article reports on the qualitative part of the study, which involved conducting semistructured interviews.
In June 2019, within the framework of a joint cooperation between the Ministry of Health and UNICEF to implement the global initiative ‘Child Friendly Cities’ in Iran, the first meeting of the National Child-Friendly City Coordination Committee was held at the Ministry of Interior of Iran. 12 cities, including Tehran, were selected to implement the Child-Friendly Cities framework. The population of children under the age of 6 in Tehran was 1 330 646 according to 2015 census. 26 Currently, Tehran and other selected cities are in the neighbourhood assessment phase. 27 For the purpose of this research, we define a child as someone who is less than 6 years old. Hence, the objective of this research was to investigate the viewpoints and encounters of specialists, municipal employees and mothers with children aged 6 and below in Tehran with regard to the creation of a child health-oriented community for this particular age group.
This was a qualitative study. Qualitative data were analysed using the directed content analysis method, which allowed new themes to emerge from the data. 28 This research used the Child-Friendly Cities framework developed by UNICEF.
Variation purposeful sampling techniques were used to recruit participants from the three main groups of experts, mothers and city council staff. Individuals with expertise and experience in infant psychology, urban planning and architecture, and health education and promotion comprised the experts. Tehran’s Child-Friendly Cities Secretariat employed the municipal personnel. Mothers were included in the research as representatives of children under the age of 6 as they are the person most responsible for their care. Experts were interviewed at their workplace, while mothers who accompanied their children in parks were interviewed in the park.
Before starting the interview sessions, an official letter from the university was provided to the participants. The participants (mothers and experts) were provided with an explanation of the study and consent was obtained for participation (mothers and experts) and for conducting and recording the interviews.
Data were collected via semistructured, indepth interviews. The interviews were conducted face-to-face using an interview topic guide ( online supplemental file 1 ). The principal investigator (PA), who had previous experience in qualitative data collection, interviewing and interview calibration, and who was unknown to the participants, conducted the interviews.
The subject of the interview was the opinion of the interviewees on the current state of their neighbourhoods and the changes that should be made to make neighbourhoods suitable and health-friendly to children under 6 years of age. The duration of the interview ranged from 20 to 60 min. Data saturation was verified by the research team after conducting 31 interviews. Nevertheless, three additional interviews were conducted to provide additional confirmation. In the end, no new data were discovered and the interview procedure was terminated. The study did not include any withdrawals from the participants. To improve the quality of data collection, the interviews were audio-recorded for verbatim transcription, with the consent of the participants. They were assured that their voices would be removed after the interviews. The interviewer (PA) recorded the participants’ perspectives, thoughts and feelings about the research topic and the interviews in a notebook. The researcher took notes during data collection when necessary ( online supplemental file 2 ).
The transcribed interviews were coded by the researcher (PA) shortly after each interview using directed content analysis techniques. UNICEF’s Child Friendly Cities framework, with six main themes, guided the data analysis. MAXQDA V.2020 software was used to facilitate the data analysis. The coding process was carried out according to Graneheim and Lundman. 29 First, the transcriptions were examined word by word. The texts were then divided into units of meaning and were coded. Codes denoting a single theme were placed in a category based on a continuous comparison of similarities, differences and appropriateness. The next step classified the categories and subcategories. The summary categories and the central concept of each category were then identified. Finally, the concepts were reviewed based on the description of the internal themes considering the whole data. 29
Graneheim and Lundman’s 29 indices, including credibility, dependability, confirmability and transferability, were applied to check for accuracy and the robustness of the data analysis. Various strategies were used to increase the credibility of the data, such as member checks, long-term engagement with the subject and data review by the research team. The reliability of the findings was verified through implementation of measures such as the coding and decoding method during data analysis and documentation of all stages from inception to conclusion. Methods such as sampling with maximum diversity, detailed descriptions of the findings and the participants, sampling, the time and place of data collection, and observer control were implemented. The transferability of the findings was increased by recording all steps and the decisions made during the study and by reviewing and confirming the data analysis report by colleagues .
Participants were provided with key information such as the purpose of study, the interview method, confidentiality of the information, the right to participate or withdraw and the procedure for storing the audio file. Furthermore, verbal informed consent to participate and audio-record the interviews was obtained from the participants (mothers and experts) at the beginning of each interview. A code was assigned to each participant to protect anonymity. In addition, the researcher kept the audio files of the interviews and were not shared with anyone.
Patients and/or the public were not involved in the design, or conduct, or reporting or dissemination plans of this research.
The characteristics of the study participants are summarised in tables 1 and 2 .
Demographic characteristics of the mothers
Demographic characteristics of the experts
Analysing the qualitative interview data, the results were categorised into 6 dimensions, 21 subdimensions and 80 characteristics. The six main dimensions included neighbourhood green space, neighbourhood cultural centre, neighbourhood health centre, services in the neighbourhood, transport in the neighbourhood and security in the neighbourhood ( table 3 ).
Emerging key dimensions and subdimensions of child health-friendly neighbourhoods (from the data)
These six dimensions are explained in detail in the following sections:
Many participants believed that the presence of a park is one of the important dimensions of a child-friendly city, provided that the park has ‘playground space for children’, ‘ergonomic play equipment’, ‘attractive play equipment’, ‘creativity, art and culture in the park’ and ‘comfortable space’. They argued that the quantity and quality of these features and their use were unsatisfactory. For example, one of the mothers stated:
Part of the flooring (of the playground) is torn off, and my child once got his foot stuck on it, and fell down. They are all separated. The cracks are open. It is necessary that the floor of the park is healthy and soft. (Mother, Interview 8)
Another participant mentioned that:
Currently, playground equipment in many parks is not suitable for children of this age in terms of height. The size of children is small, and it is necessary for them to have play equipment and chairs and benches that are suitable for the size of children. (Child psychologist, Interview 22)
Some interviewees believed that there was a need for community centres to offer educational and cultural activities that were age-appropriate, attractive and varied. Many educational topics were suggested, such as ‘art and creativity’, ‘self-care’, ‘life skills’ and ‘citizenship skills’, both from educational and recreational perspectives. Many families may have limited experience or skills in educating their children, and as a result some argued that self-care education should include protection from sexual assault. Consequently, professionals can significantly contribute to this effort. For example, one of the mothers discussed this point as follows:
One of the educational points that I think my child needs now is that I don’t know what to tell him about sexual issues, and I think it is necessary that a child educator who has studied and has experience in this field should teach him/her how to protect himself/herself from sexual abuse, education based on what they need to know, to be told so that they receive knowledge appropriate for their age. (Mother, Interview 14)
Another participant explained:
My son reached the age of middle school, and he is afraid to go to the neighborhood and to the city. He is afraid of riding the bus alone, if I was a child, I would have gone to school alone … I think it is necessary to teach them about the urban lifestyle and about commuting within the neighborhoods. From preschool onwards, it is necessary to learn how to cross the street, how to cross the crosswalk and traffic lights, learn how to get on and off the bus, so that later they can use it, they don’t have to be afraid anymore. (Urban planning and architecture expert, Interview 23)
From the participants’ point of view, the neighbourhood health centre should provide ‘child health services’, ‘health education services’ and ‘child care’. Many participants were not satisfied with the child health services and health education. For example, one of the mothers said:
Health centers used to provide much better services for mothers and children, and education during pregnancy and about breastfeeding, but now they just fill in forms and do not provide any education. The health center should be a place to teach mothers how to breastfeed. how to sleep and bath the child, and to give advice and instructions to the father. (Mother, Interview 13)
One of the characteristics of a child-friendly neighbourhood according to the participants was adequate access to children’s welfare services in the neighbourhood. They explained that, unfortunately, children’s welfare services are usually neglected and therefore need to be addressed. For example, one participant explained:
My child gets very upset and nervous when he comes to the shopping mall, because it is crowded, and he has to walk in the crowd. If there are baby strollers in all shopping malls, mothers can easily take the child with them, and the children even enjoy it. (Mother, Interview 13)
Several participants had suggestions for the creation of "children's entertainment and sports centers" in the neighborhood. These centres can be, for example, sports centres that have sports and swimming pools for children. For example, one participant pointed out:
Every neighborhood can have grass playgrounds for children, as well as indoor sports centers, for example, a children’s pool and they can play. (Urban planning and architecture expert, Interview 16)
The participants argued that the sidewalks, streets and generally the environment for transporting children in the neighbourhood should be ‘easy to use’, ‘attractive’, ‘educational’, ‘safe’ and ‘ergonomic’. One of the participating mothers said:
The most important problem I have is that I can’t take my baby out with the stroller, the sidewalks are full of stairs and up and down, you have to constantly lift and move the stroller with its weight, and when you take it on the street, cars honk and drive by at high speed. (Mother, Interview 13)
Another participant explained about the safety of shrubs or trees planted on the streets:
It is better to plant tall trees in front of houses or low annual flowers and plants. We have had many cases where a child who was crossing the sidewalk, the blade of these shrubs hit him in the face and injured him, or their leaf has got stuck in his clothes. (Public health specialist, Interview 22)
One participant highlighted the need for traffic signs to be ergonomically designed for children under the age of 6:
It is necessary that the green and safety light for the child and appropriate to the height of the child and the environment be considered from the origin which is the home of each child, to the destination where is a space designed for children, so that both drivers are required to obey the traffic law, and children feel safe from the presence of cars on the street to travel. (Urban planning and architecture expert, Interview 16)
Some participants argued that the frequency of the child's presence in the neighborhood could be increased by improving the "attractiveness of the child's walking route," for example by incorporating vegetation and painted walls. Some other participants argued that the presence of ‘child friendly urban furniture’ in the neighbourhood space that is based on the height and size of children under 6 years of age can facilitate the child’s passage in the neighbourhood as it allows them to rest when needed.
Neighbourhood safety for children is an important dimension of a child health-friendly city that was frequently discussed by the participants. They discussed children's security from strangers and addicts in all areas of the neighborhood, especially in "parks," which are the main neighborhood spaces used by young children. For example, a participant explained:
Security is very important in educational spaces. In these environments, it is necessary that CCTV [closed-circuit television] is controlled and there is surveillance. This security leads to the reduction of anxiety and stress in the city and neighborhood, the space that has a camera and is monitored creates a sense of security for the presence of the child, and the family can trust that place. (Specialist in urban planning and architecture, Interview 27)
A mother stated:
I can’t allow my daughter to play alone even in front of our door. I have often seen drug addicts going to the street and exchanging drugs. (Mother, Interview 10)
The health of urban populations is directly affected by the ability of the urban environment to support the creation of safe neighbourhoods and healthy behaviours and habits during childhood. 30 Living in cities can expose children to risks and challenges, such as noise and air pollution, sedentary lifestyles, traffic hazards, crime, social isolation and disconnection from nature. However, it can also provide health-promoting resources and opportunities, such as education and healthcare. 30 31
There is a limited number of studies that have documented the effect of neighbourhoods on children’s health. 32 33 For instance, Dondi et al ’s 34 study demonstrated that exposure to toxic air pollutants during infancy and childhood can affect the growth and development of the respiratory system, nerves, glands and immune system. Furthermore, it has the potential to elevate the likelihood of developing cancer in the future. It is estimated that the 1.7 million fatalities among children under the age of 5 each year are a result of disregard for the health and environmental aspects in cities. 31 32 Therefore, cities should provide a platform to protect children’s health based on their needs. 30
One of the challenges to implementing the concept of a child-friendly city is the difficulty in accurately identifying the needs of children that the city can provide for, given the large scale of the city and with inadequate research. 35 We focused on the smaller scale of the neighbourhoods and consulted with stakeholders, particularly mothers, to gain a more comprehensive understanding of the needs of children living in urban areas. This approach can be considered a strength of our study. The present study investigated the health needs of children that can be addressed by the neighbourhood. The perspectives of three key stakeholders, namely experts, city council staff and mothers, were explored. A qualitative approach was employed to gain a deeper understanding of their experiences and perspectives. Previous studies in this field have mostly taken a quantitative approach. 36–40
The importance of the local environment in the health of children was underscored by the participants in this study, as indicated in the Results section. The participants suggested specific characteristics for various locations in the community that can support the preservation and promotion of health of children aged 0–6 years. Through data analysis, six dimensions were identified for a child-friendly neighbourhood, which closely resembled the seven dimensions of UNICEF’s Child Friendly Cities concept, 41 as presented in table 4 . However, a total of 80 child-friendly neighbourhood characteristics were developed, 23 of which were new items compared to the current UNICEF child-friendly city checklist. Some of these newly identified characteristics have been reported by other researchers 27 38 42 . However, there were few characteristics that were not reported in other studies, such as access to mother and child rooms in parks, sexual self-care education in child care facilities and child education centers, mental health screening for children, and child-friendly urban furniture.
Comparison among the identified domains of a child health-friendly neighbourhood for children under 6 years of age (from the data) and the UNICEF’s Child Friendly Cities framework 42
Security was a common concern among the participants, particularly among mothers. The discussion on neighbourhood security included parks, educational spaces and the surrounding area. Security has both objective and subjective dimensions. Objectively, it refers to the absence of danger and threats to a child’s life. 43 Subjective security, on the other hand, refers to an individual’s (here children or mothers) feeling of calmness and intimacy with a space, regardless of whether there is an actual hazard present. 44 According to other studies, children’s presence in a neighbourhood may be impacted by the perceived or actual security issues. 44–46 It is crucial to remember that in order to preserve objectivity, subjective assessments must be identified as such. 45 Therefore, it is essential to address the dark and hidden corners of the neighbourhood, provide proper lighting, install security cameras and if possible have security guards in the areas. 46
Although this study provided rich perspectives on the characteristics of a child health-friendly neighbourhood from three groups of stakeholders, due to lack of time we did not obtain the opinions of fathers and children. It should also be noted that, first, due to the qualitative nature of the study, only the typology of perspectives was provided rather than the prevalence of perspectives among the participants interviewed. In other words, the results cannot indicate what the main problems are that need to be addressed in the neighbourhoods. Also, the needs of children in each neighbourhood may be different. Quantitative research is therefore needed to identify priorities for future action. Due to the complexity, multidimensionality and subjectivity of the dimensions of health in the neighbourhood, we used a qualitative method. However, in order to assess and identify the existing needs of a neighbourhood, quantitative research is needed to evaluate these components so that we can identify the existing gaps for appropriate interventions.
The results of this study provide a deeper understanding of the health needs of children under 6 years of age that need to be met in order to provide a child-healthy neighbourhood. Thus, it contributes to further dialogue, research and intervention design to make neighbourhoods a health-supportive environment as recommended by the Ottawa Charter for Health Promotion. We suggest that in designing child-friendly cities and neighbourhoods, it is critical to take a comprehensive approach to the health needs of children of all ages, especially those aged 0–6. This involves providing secure and healthy settings and services in the neighbourhoods, as well as ensuring that natural and manmade infrastructure and services are responsive to children’s actual health requirements. To this end, this study highlighted the importance of access to neighbourhood green space, health services, transportation and security.

Introduction. Recognition has grown that while quantitative methods remain vital, they are usually insufficient to address complex health systems related research questions. 1 Quantitative methods rely on an ability to anticipate what must be measured in advance. Introducing change into a complex health system gives rise to emergent reactions, which cannot be fully predicted in advance.
The use of mixed methods to study complex social phenomenon goes back to the mid 19th century where most investigators started using both qualitative and quantitative approaches in single studies (Maxwell, 2016).For instance, in 1898, DuBois engaged in field work to obtain data while studying 8000 inhabitants of a slum in Philadelphia, using in-depth house-to-house interviews, a phenomenon ...
