ConPHES (CONsensus-based Process evaluation reporting guidelines for public Health intErvention Studies)


Process evaluations of are essential for understanding how impact is (not) achieved in practice and to understand the relations between implementation, mechanisms, and context in which these impacts are achieved (Moore et al 2015).

Unlike guidelines for efficacy and effectiveness trials, there is currently no consensus on how to report process evaluations for Public Health intervention studies. In a recent systematic review among school-based obesity-prevention program evaluations, process evaluation reports were mostly inadequate and incomplete and showed a very broad variety in how the process evaluation was conducted and reported (Schaap, 2018).

Although there are many frameworks, theories and models for process evaluations, such as the RE-AIM framework (Glasgow, 1999), UK-MRC process evaluation model (Moore, 2015) and Durlak and Dupre’s model (2008), there is currently no standardized, scientifically recognized guideline for reporting process evaluation studies of public health intervention studies, impeding transparency, replication and comparisons.

Project plan

Therefore, the aim of this project is to develop consensus- and expert-based guidelines for reporting process evaluations of public health intervention studies.

The project is divided into 7 steps.

  1. Literature search (January – May 2020):
  2. Consensus-building e-Delphi study (May – September 2020)
  3. Translate the results into the new guideline and an Explanation and Elaboration document. (October-November 2020)
  4. Pilot test (November 2020)
  5. Sign Off phase (December 2020)
  6. Dissemination of the new guideline (December 2020)
  7. Official launch at the European Implementation Science conference (May 2021)
