A modified Process Evaluation Rating Sheet (PERS) showed implementation quality linked to workplace weight loss program success. However, these benefits diminished over time, highlighting the need for ongoing evaluation.
Area of Science:
- Occupational Health
- Behavioral Science
- Program Evaluation
Background:
- Workplace wellness programs are crucial for employee health.
- Evaluating the quality of program implementation is essential for understanding efficacy.
- The Process Evaluation Rating Sheet (PERS) is a tool for assessing implementation.
Purpose of the Study:
- To assess the effectiveness of a modified PERS in evaluating workplace weight loss programs.
- To determine the relationship between implementation quality and program efficacy.
- To analyze program outcomes including organizational health and supervisor support.
Main Methods:
- Utilized Spearman correlations and hierarchical regressions.
- Assessed implementation quality using a modified PERS.
- Measured program efficacy with the Multifaceted Organizational Health Climate Assessment (MOHCA) and Job Content Questionnaire (JCQ).
Main Results:
- 407 workers across 11 workgroups participated.
- Higher PERS scores correlated with sustained improvements in organizational health and supervisor support.
- Improvements were not sustained at the 24-month mark.
Conclusions:
- Implementation quality is associated with workplace health program efficacy.
- The association between implementation quality and efficacy fades over time.
- The modified PERS can improve the evaluation of workplace health behavior change initiatives.
