Validation and dimensionality of the Integration of Health Protection and Health Promotion Score: evidence from the PULSE Small Business and VA Medical Center surveys
- View All
OBJECTIVE: To conduct validation and dimensionality analyses for an existing measure of the integration of worksite health protection and health promotion approaches. METHODS: A survey of small to medium size employers located in the United States was conducted between October 2013 and March 2014 (N = 115). A survey of Department of Veterans Affairs (VA) administrative parents was also conducted from June to July 2014 (N = 140). Exploratory factor analysis (EFA) was used to determine the dimensionality of the Integration Score in each sample. RESULTS: Using EFA, both samples indicated the presence of one unified factor. The VA survey indicated that customization improves the relevance of the Integration Score for different types of organizations. CONCLUSIONS: The Integration Score is a valid index for assessing the integration of worksite health protection and health promotion approaches and is customizable based on industry. CLINICAL SIGNIFICANCE: The Integration Score may be used as a single metric for assessing the integration of worksite health protection and health promotion approaches in differing work contexts.
