Background Behavior adherence is essential to prevent the onset and development of sarcopenic disease in the older adults. However, to date there has been no appropriate scale to measure the level of sarcopenia prevention behavior adherence in older adults. This study aims to develop and psychometrically test sarcopenia prevention behavior adherence scale for older adults. Methods Using item development and psychological assessment of two processes.First, a literature review,Delphi study, and pre-survey were used to construct a scale for adherence to sarcopenic prevention behavior in older adults.Second, a large sample survey was conducted on 445 older adults.Item analysis, exploratory factor analysis, and confirmatory factor analysis were used to optimize the scale.The Cronbach's α coefficient was calculated as a reliability analysis.The validity analysis included construct validity, convergent validity, discrimination validity, and content validity. Results A 3-dimensions 18-items scale was developed, including diet behavior, exercise behavior, and resource utilization behavior.The confirmatory factor analysis supported the three-factor model, and the convergent and discriminant validity levels were satisfactory.The Cronbach's α coefficient of the scale was 0.921 and the content validity index was 0.957. Conclusions The scale developed in this study is a reliable and valid tool for assessing the level of behavior adherence to sarcopenia prevention for older adults.More studies are needed to examine the robustness of its structure.
