Evaluating the Implementation of a Workplace Weight Loss Program Using a Modified Process Evaluation Rating Sheet.

Abstract

The aim of this study was to demonstrate the utility of a modified Process Evaluation Rating Sheet (PERS) for analyzing implementation quality and program efficacy in a workplace weight loss program. Health care system workgroups formed teams to implement weight loss activities between 2018 and 2020. We used Spearman correlations and hierarchical regressions to examine associations between implementation quality captured by the modified PERS and program efficacy outcomes such as organizational health climate and supervisor support measured by the Multifaceted Organizational Health Climate Assessment and Job Content Questionnaire. Four hundred seven workers from 11 workgroups participated. Workgroups with high PERS scores sustained improvement in Multifaceted Organizational Health Climate Assessment and Job Content Questionnaire scores. No group sustained improvements at 24 months. Implementation quality was associated with program efficacy, but the association faded over time. Utilizing the modified PERS may enhance evaluation of workplace health behavior change programs.
