Quantitative Measurements for Factors Influencing Implementation in School Settings: Protocol for A Systematic Review and A Psychometric and Pragmatic Analysis.

Introduction: In order to address the effectiveness and sustainability of school-based interventions, there is a need to consider the factors affecting implementation success. The rapidly growing field of implementation-focused research is struggling to determine how to assess and measure implementation-relevant constructs. Earlier research has identified the need for strong psychometric and pragmatic measures. The aims of this review are therefore to (i) systematically review the literature to identify measurements of the factors influencing implementations which have been developed or adapted in school settings, (ii) describe each measurement's psychometric and pragmatic properties, (iii) describe the alignment between each measurement and the corresponding domain and/or construct of the Consolidated Framework for Implementation Research (CFIR).

Methods: Six databases (Medline, ERIC, PsycInfo, Cinahl, Embase, and Web of Science) will be searched for peer-reviewed articles reporting on school settings, published from the year 2000. The identified measurements will be mapped against the CFIR, and analyzed for their psychometric and pragmatic properties.

Discussion: By identifying measurements that are psychometrically and pragmatically impactful in the field, this review will contribute to the identification of feasible, effective, and sustainable implementation strategies for future research in school settings.
