NARRATIVE SYNTHESIS: A METHODOLOGY REVIEW
Developing methods for the narrative synthesis of quantitative and qualitative data in systematic reviews of effects
BackgroundTo date statistical approaches to combining findings from different studies have received most attention in the systematic review literature. However, these techniques are not always appropriate for quantitative data and are unlikely to be relevant to the synthesis of findings from qualitative research or from mixed method studies. These studies provide evidence on the implementation and experience of those involved in the interventions, which, combined with evidence on outcomes, can increase the utility of systematic reviews for policymakers and practitioners. In this context narrative approaches to the synthesis of evidence from multiple studies are being developed. However, unlike statistical meta-analysis, these narrative approaches do not rest on an authoritative body of knowledge about how to ensure rigour and reliability.
On the basis of a critical analysis of methodological literature and of existing approaches to narrative synthesis in a sample of systematic reviews, we developed a framework, incorporating a collection of tools and techniques, to guide the conduct of narrative synthesis in the context of systematic reviews.
We demonstrated the way in which the guidance might be applied in two guidance-led syntheses of previously reviewed data. These suggested that the guidance is flexible and can contribute to increased transparency in the narrative synthesis process.Conducted by: J Popay1, H Roberts2, A Sowden3, M Petticrew4, N Britten5, L Arai2, K Roen1, M Rodgers3
