Objective: To develop a questionnaire on the psychological driving factors of physical activity for the older adults, and test its reliability and validity, provide an effective tool for the systematic assessment of the psychological driving factors of physical activity in the older adults, and further offer references for the precise formulation of older adults health promotion programs. Methods: Using the Theory of Planned Behavior as the framework, an initial questionnaire item pool was formed through literature review, expert consultation, and pre-survey. From January to June 2024, 413 older adults from 8 communities in Xinxiang, Henan province were conveniently recruited as research participants for questionnaire item analysis, reliability testing, and validity testing. Results: The final questionnaire comprised 17 items. The average content validity of the questionnaire was 0.905, and the content validity at the item level ranged from 0.870 to 1.000. Exploratory factor analysis extracted 4 common factors, with a cumulative variance contribution rate of 73.734%. Results of confirmatory factor analysis showed that χ2/df=2.828, RMSEA=0.078, SRMR=0.056, IFI=0.928, TLI=0.913, and CFI=0.928, indicating a good model fit. The overall Cronbach's α coefficient of the questionnaire was 0.939, split-half reliability was 0.830, and test-retest reliability was 0.877. Conclusion: This questionnaire has good reliability and validity, and can effectively assess the psychological driving factors of physical activity in older adults, providing reliable tool support for clinical medical staff and community health workers to formulate targeted older adults health promotion strategies.
