Purpose: The purpose of this paper is to examine the quantitative measurement tools used in fields of study related to coproduction, as an approach to mobilizing knowledge, in order to inform the measurement of impact. Design/methodology/approach: An overview methodology was used to synthesize the findings from prior instrument reviews, focusing on the contexts in which measurement tools have been used, the main constructs and content themes of the tools, and the extent to which the tools display promising psychometric and pragmatic qualities. Findings: Eight identified reviews described 441 instruments and measures designed to capture various aspects of knowledge being mobilized among diverse research stakeholders, with 291 (66%) exhibiting relevance for impact measurement. Research limitations/implications: Future studies that measure aspects of coproduction need to engage more openly and critically with psychometric and pragmatic considerations when designing, implementing and reporting on measurement tools. Practical implications: Twenty-seven tools with strong measurement properties for evidencing impact in coproduction were identified, offering a starting point for scholars and practitioners engaging in partnered approaches to research, such as in professional learning networks. Originality/value: Current quantitative approaches to measuring the impacts of coproduction are failing to do so in ways that are meaningful, consistent, rigorous, reproducible and equitable. This paper provides a first step to addressing this issue by exploring promising measurement tools from fields of study with theoretical similarities to coproduction.
