Objective:To translate the English version of the health enhancement lifestyle profile-screener into Chinese and assess its reliability and validity based on classical test theory(CTT) and Rasch model among the elderly.Methods:A total of 447 older adults from rural and urban areas in Sichuan Province from December 2020 to March 2021 were selected by convenience sampling, and were surveyed with the revised Chinese version of health enhancement lifestyle profile-screener(HELP-CS). Rasch and CTT-based approaches were used to evaluate the unidimensionality data-model fit, internal consistency, test-retest reliability, criterion validity and discriminant validity of the questionnaire.Results:According to the results of the initial test questionnaire, the ninth question was deleted, and 14 items were retained to form a formal questionnaire. The formal test results showed that HELP-CS met the unidimensionality, and the residual mean square error for item 2 and 14 were within the acceptable range, which were 1.49 and 1.41. Item 10 and 12 had the highest logits, which were 1.87 and 1.91 respectively. There were gender differences in some topics. The Cronbach′s α of the scale was 0.719, and the test-retest reliability was 0.704 after two months. The criterion correlations with HPLP-CE were 0.581.Conclusion:HELP-CS has good adaptability, reliability and validity in the elderly, and can be used as a quick and effective screening tool in the study of the lifestyle of the elderly.
