Validation of Performance Indicators for Evaluation of Workplace Health Promotion.

Abstract

To validate performance indicators for evaluating workplace health promotion (WHP) programs based on a logic model and to analyze the structural relationships between constructs. The study design is cross-sectional. Design setting was small manufacturing companies implementing WHP programs provided by the Korea Industrial Health Association. Seventeen occupational health experts completed a questionnaire to determine the content validity of indicators. In addition, 58 health care managers completed a questionnaire to determine reliability and construct validation. The response rate was 84.1%. Based on a logic model, 13 constructs of WHP programs were identified: WHP program input, four activities for workplace environment management, two activities for employee health care management, two outputs, and two short-term outcomes. Interrater agreement index was used for testing the content validity of indicators. Confirmatory factor analysis was used to test for the reliabilities, and the convergent and discriminant validities. Structuring equation modeling was also used to analyze the relationships among constructs. A total of 35 performance indicators from 11 constructs showed good reliability and validity. All relationships among WHP input, activities, outputs, and short-term outcomes were significant, except for the relationship between environment outputs and short-term outcome. These findings illustrate that the logic model and structuring equation modeling can be used to develop and validate performance indicators for planning and evaluation of the WHP program.
