Objective : This study aimed to translate the Health Promoting Activities Scale (HPAS) for mothers of children with disabilities into Korean and verify its content and face validity. Methods : The study period was from August 26 to November 6, 2025. The HPAS was translated and back-translated, and two Delphi surveys were conducted with 11 experts to verify content validity. To verify face validity, a survey was conducted with 10 mothers of children with disabilities. Data were analyzed to calculate the content validity ratio (CVR), mean, and standard deviation. Results : The first Delphi survey revealed a CVR of 0.27∼0.82, with a mean of 4.1∼4.7. In the first survey, experts suggested using consistent wording, using intuitively understandable wording, providing examples appropriate for Korean culture, and incorporating diverse religions. In the second Delphi, the CVR ranged 0.82∼1.00, with an average score of 4.7∼5.0. Recommendations included revising spiritual expressions and removing specific religious designations. A survey of mothers of children with disabilities revealed an average score of 4.2∼4.8. They recommended removing spiritual expressions and providing concrete explanations for ambiguous expressions. Furthermore, we were able to develop content tailored to Korean culture contexts by providing information about the specific activities they actually participate in. Conclusion : The K-HPAS is a tool that systematically measures the health promoting activities participated in by mothers of children with disabilities. It is expected to serve as a foundation for future health promoting program development and personalized health management.
