title: Development and Validity Testing of the Worksite Health Index: An Assessment Tool to Help and Improve Korean Employees' Health-Related Outcome.
abstract: The objective of this study was to develop the Worksite Health Index (WHI) and validate its psychometric properties.
  
  
  
  The development of the WHI questionnaire included item generation, item construction, and field testing. To assess the instrument's reliability and validity, we recruited 30 different Korean worksites.
  
  
  
  We developed the WHI questionnaire of 136 items categorized into five domains, namely Governance and Infrastructure, Need Assessment and Planning, Health Prevention and Promotion Program, Occupational Safety, and Monitoring and Feedback. All WHI domains demonstrated a high reliability with good internal consistency. The total WHI scores differentiated worksite groups effectively according to firm size. Each domain was associated significantly with employees' health status, absence, and financial outcome.
  
  
  
  The WHI can assess comprehensive worksite health programs. This tool is publicly available for addressing the growing need for worksite health programs.
