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

RATIONALE

As the global population ages, there is a growing need for tools to assess lifestyle factors that impact the health and quality of life of older adults. The Yonsei Lifestyle Profile (YLP), originally developed in South Korea, is a comprehensive tool for evaluating key lifestyle domains. However, cultural and linguistic differences between countries necessitate the adaptation of such tools for use in diverse populations. This study addresses the gap by developing an English version of the YLP (YLP-E) for older adults in the United States.

AIMS AND OBJECTIVES

As the global population continues to age, maintaining and improving the health and quality of life of older adults has become increasingly important. This study aimed to develop a YLP-E, a cross-cultural adaptation of the Korean version of the YLP, that can be used for older American adults.

METHOD

The Delphi method was used to consult expert panels regarding the cultural and linguistic appropriateness of the translation. The translation process involved a two-way translation-back-translation procedure and iterative revisions based on expert feedback.

RESULTS AND CONCLUSIONS

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.
