Reliability and validity test of the Chinese version of the HIV Treatment Regimen Fatigue Scale
Objective To translate and adapt the English version of the HIV Treatment Fatigue Scale for Chinese HIV/AIDS patients,assessing its reliability and stability to ensure it provides a dependable tool for evaluating treatment fatigue.Methods The English version was translated into Simplified Chinese through systematic translation,back-translation,and revision.The study involved participants from two designated AIDS treatment institutions.Cronbach's alpha coefficient was employed to evaluate the scale's internal consistency.The scale's content validity,structural validity,and construct validity were also assessed.Results We collected 767 valid questionnaires.Exploratory factor analysis retained all 22 items from the original scale,resulting in a Cronbach's alpha coefficient of 0.838.Two common factors were identified:"mental fatigue"and"self-efficacy,"with Cronbach's alpha coefficients of 0.902 and 0.821,respectively.Confirmatory factor analysis revealed that all item factor loadings exceeded 0.50(P＜0.001).Composite reliability scores were 0.901 and 0.814,and average variance extracted values were 0.380 and 0.387,respectively.The square roots of these values surpassed the factor correlation coefficients,affirming strong construct validity.Additionally,38.07％of respondents reported experiencing fatigue.Conclusions The Chinese version of the HIV Treatment Fatigue Scale exhibits robust reliability and validity,making it an effective measurement tool for assessing treatment fatigue among Chinese patients with HIV/AIDS.
