The questionnaire includes self-reported demographic characteristics, the modified version of the Community Programs for Clinical Research on AIDS Antiretroviral Medication Self-Report (CPCRA) and LW-IMB-AAQ. CPCRA was used to calculate ART adherence. LW-IMB-AAQ, including the information section, the motivation section and the behavioral skills section, was used to analyze patients’ ART adherence. We analyzed data by means, standard deviation, critical ratio, and item-total correlation. Reliability was assessed by internal consistency, split-half reliability, and test–retest reliability. Validity was assessed by exploratory factor analysis (EFA), confirmatory factor analysis (CFA), convergent validity and discriminant validity.Results: Item analysis showed that except for motivation item 1, all items were acceptable. For reliability, Cronbach’s alpha coefficients for the three sections and the total scale were all higher than 0.7, with interclass correlation coefficients (ICC) all higher than 0.6 (p< 0.001). The Spearman–Brown coefficient for the total scale was 0.825. For validity, results showed that the information section could be divided into two subscales, motivation section and behavioral skills section could be divided into three and two subscales, respectively. The final model demonstrated good validity (p=0.471, χ 2/df=0.960, CFI=1.000, GFI=0.994 and RMSEA< 0.001) without motivation item 4.Conclusion: Excluding motivation items 1 and 4, the LifeWindows Information–Motivation–Behavioral Skills ART Adherence Questionnaire (LW-IMB-AAQ) demonstrated good validity and reliability among HIV+ patients in Shanghai.Keywords: HIV, validity, reliability, IMB model, China
