Psychometric properties of moore version of World Health Organization's Quality of Life (WHOQOL) HIVBREF in persons living with HIV in Burkina Faso

Abstract

This study aims to examine psychometric properties of Moore version of World Health Organization's Quality of Life assessment short instrument in HIV patients (WHOQOL HIV-BREF). A study was conducted on 100 persons living with HIV/AIDS in Ouagadougou, Burkina Faso. The internal consistency was evaluated using Cronbach's α. For the convergent validity of the Moore version WHOQOL-HIV BREF, the Satisfaction With Life Scale (SWLS) was used as a comparison instrument and cross-product correlations were calculated. The test-retest reliability was assessed using the interclass correlation coefficient. The study showed high internal consistency with Cronbach's α at 0.92 for the whole instrument. According to domains, Cronbach's α found was ranged from 0.58 to 0.87, showing acceptable internal consistency for all domains. Domains scores for test-retest reliability, using Interclass Correlation gave coefficients ranged from 0.40 (Spiritual domain) to 0.99 (Level of Independence domain) with p0.05). As a demonstrated cross-cultural instrument, the WHOQOL HIV-BREF in its Moore version can be used for quality of life assessment in a routine way or longitudinal studies in Burkina Faso with persons living with HIV/AID
