Reliability of an Assessment Tool and Outcomes of a Comprehensive Worksite Wellness Intervention.

Abstract

The purpose of this study was to determine the reliability of a comprehensive worksite-level assessment and identify which worksite wellness best practices were implemented following a workshop. Kansas worksites attended a WorkWell Kansas Phase I workshop from 2012 through 2014 and completed a 155-item assessment before the workshop and 1 year later. Cronbach alpha measured the internal consistency of the WorkWell KS Phase I Assessment, and McNemar test assessed differences in proportions from baseline to follow-up. Two hundred eighty five worksites completed a baseline assessment, of which, 109 completed the follow-up assessment (32%). The internal consistency of the instrument was 0.96, and worksites reported significant improvements at follow-up from baseline for nine variables. Improvements predominantly included creating a wellness committee, assessing needs, and developing goals. There was a lack of policy and systems level improvements at the worksite.
