Abstract

Introduction: The aim of this study was to assess validity and reliability of Persian version of quality of life (QOL) questionnaire in people living with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) (WHOQOL-HIV-BREF). Material and methods: A total of 150 HIV/AIDS patients who were referred to Fasa and Larestan Beha vioral Disease Counseling Centers were recruited into the study. WHOQOL-HIV-BREF questionnaire was completed by trained interviewers. Reliability of questionnaire was measured using Cronbach’s a coefficient. Construct validity was assessed by item-scale correlation method, and criterion validity was determined with discriminant validity and convergent validity. Results: Cronbach’s α was computed above 0.8 for all dimensions of the questionnaire. Item-convergent validity ranged from 0.38 to 0.83. QOL score was higher in AIDS patients compared with HIV-infected individuals in all dimensions (p < 0.01). Conclusions: The findings of this study show that WHOQOL-HIV-BREF questionnaire provide acceptable validity and reliability for measuring QOL among Persian-speaking HIV/AIDS-infected patients in Iran.
