Objective: To conduct validation analyses for a new measure of the integration of worksite health protection and health promotion approaches developed in earlier research.

Methods: A survey of small- to medium-sized employers located in the United States was conducted between October 2013 and March 2014 (n = 111). Cronbach α coefficient was used to assess reliability, and Pearson correlation coefficients were used to assess convergent validity.

Results: The integration score was positively associated with the measures of occupational safety and health and health promotion activities/policies—supporting its convergent validity (Pearson correlation coefficients of 0.32 to 0.47). Cronbach α coefficient was 0.94, indicating excellent reliability.

Conclusions: The integration score seems to be a promising tool for assessing integration of health promotion and health protection. Further work is needed to test its dimensionality and validate its use in other samples.
