Development and Validation of the Health-Friendly Activity Index: An Assessment Tool to Improve Consumers’ Health-Related Outcomes

Abstract Objectives We developed the Health-Friendly Activity Index (HFAI) to measure the health-friendly activity of corporations or organizations comprehensively. We validated the developed tool and reported on its use as an assessment tool to improve consumers’ health-related outcomes.Study Design This is a cross-sectional studyPUBH-D-20-02610 Development of the HFAI questionnaire followed a three-phase process: item generation, item construction, and validation with field testing. Using relevance and feasibility criteria, we developed a 105-item questionnaire with six domains (Governance and Infrastructure, Needs Assessment, Planning, Implementation, Monitoring and Feedback, and Outcomes). To assess the sensitivity and validity of the questionnaire, we recruited two different groups. We assessed Group One (31 companies) based on their recent sustainability reports and compared their HFAI scores with the Contribution Assessment Tool for Consumer’s Health (CATCH) scores from 400 people from the general Korean population. For Group Two, we recruited 19 worksites and asked them to complete the HFAI and CATCH.Results Each domain of HFAI exhibited a Cronbach’s α coefficient between 0.382 and 1.000 for Group One and a Cronbach’s α coefficient between 0.676 and 0.938 for Group Two.
