How does participatory research work: protocol for a realist synthesis.

INTRODUCTION

Participatory research science deals with partnerships underlying research, governance and ownership of research products. It is concerned with relationships behind research objectives and methods. Participatory research has gained significant traction in design of health interventions, contextualising these to local settings and stakeholder groups. Despite a massive increase in participatory research exercises, the field remains undertheorised, and the mechanisms for improving health outcomes remain unclear. This realist review seeks to understand how and under what circumstances participatory research impacts health and social outcomes.

METHODS AND ANALYSIS

The review will follow four steps: (1) searching for and selecting evidence, (2) assessing the quality of evidence, (3) extracting and categorising data and (4) synthesising the data in the form of context-mechanism-outcomes configurations. The review will follow the Realist And Meta Narrative Evidence Syntheses: Evolving Standards (RAMESES) II guidelines for reporting realist evaluations. We categorise and synthesise data in four steps: (1) identifying outcomes, (2) identifying contextual components of outcomes, (3) theoretical redescription (abduction) and (4) identifying mechanisms. A retroductive analysis will identify mechanisms by moving between empirical data and theories, using inductive and deductive reasoning to explain the outcomes-context matches. The output will generate middle-range theories on how participatory research works, for whom and under what circumstances.

ETHICS AND DISSEMINATION

This study is a review of a published literature. It does not involve human participants. We will convene a workshop to share and discuss the preliminary results with partners and key stakeholders involved in participatory health research. We will publish the review results in peer-reviewed journals and academic conferences.
