Abstract:
The purpose of this study was to assess the individual quality of life in HIV-infected/AIDS patients by Patient Generated Index (PGI) and test psychometric properties. Practicality was assessed with average time of administration, refusal rate and difficulty rating. Reliability was evaluated by using intraclass correlation coefficients (ICCs) for test-retest reliability assesment. Construct validity was supported with convergent validity using correlation among EQ-5D, MOS-HIV Thai version, sociodemographic parameter, clinical parameter and PGI scores. Responsiveness was supported with standardized effect size (SES) and standardized response mean (SRM). Subjects were 210 HIV-infected/AIDS outpatients HIV at Warinchumrab hospital. It was found that PGI reported the factors cited by HIV-infected/AIDS patients and antiretroviral drugs affecting their quality of life were 27 domains. The most important domains nominated were dyslipidemia, lipodystrophy, hepatitis, chronic fever, fatique, weight loss, chronic diarrhea, and coma drug allergies. The average time of administration approximately was 15 minutes and difficulty rating was 3.72. ICCs was 0.691. There were significantly low correlations among EQ-5D, MOS-HIV Thai version, sociodemographic parameter, clinical parameter and PGI scores. In addition, PGI score has large effect sizes especially in better health condition. Conclusion, the PGI reported the domains cited by HIV-infected/AIDS patients and antiretroviral drugs. It has acceptable reliability and responsiveness to be use to assess the health-related quality of life in HIV-infected/AIDS patients.
