Cross‐Cultural Adaptation and Content Validation of the Yonsei Lifestyle Profile for Older Adults in the United States

The final YLP-E tool, which incorporated feedback on linguistic and cultural adequacy, consisted of 3 lifestyle domains (physical activity, activity participation and nutrition) with 62 items. The second round improved the content validity, with the linguistic content validity ratio (CVR) and cultural CVR reaching 0.86 and 0.94, respectively. The YLP-E is a valuable tool for comprehensively assessing and monitoring the lifestyle of older American adults and holds promise for further refinement and validation across diverse demographic settings. Future research needs to focus on utilizing the YLP-E to develop personalized interventions aimed at improving the health and quality of life of older adults and evaluating the tool's efficacy in promoting healthy aging.
