Objective : : This study aimed to validate the Yonsei Lifestyle
Profie-BREF (YLP-BREF) and preliminarily investigate its psychometric properties |
Methods : : In total, 569 community-dwelling older adults were
recruited. Confirmatory factor analysis was conducted. Also,
convergent and divergent validity were assessed. Additionally,
Cronbach’s alpha reliability was examined. Finally, an optimal
cutoff score for the YLP-BREF was established using receiver
operating characteristic curve analysis. |
Results :The one-factor model was the best fit. The 5 items of
physical activity and the 4 items of activity participation illustrated an acceptable fit. All nutrition items showed an acceptable
fit. Cronbach’s alpha reliability was good for the total score and
nutrition and acceptable for physical activity, but insufficient for
activity participation. Convergent and divergent validities were
good. The optimal cutoff score for the YLP-BREF was 49. |
Conclusion : The YLP-BREF is a reliable and valid self-report
questionnaire for measuring multifaceted lifestyle factors in
older adults in South Korea |
