Psychometric properties of moore rendition of World Health Organization's Personal satisfaction (WHOQOL) HIV-BREF 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 human immunodeficiency virus infection and acquired immune 
deficiency syndrome (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 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 p < 0.001 for all domains except 
for spirituality domain (p < 0.05). The study showed significant correlation between general facets and 
quality of life score (p < 0.001), as wheel as WHOQOL HIV-BREF and satisfaction with life scale (p < 0.01) 
except for spirituality domain. The instrument demonstrated good discriminative properties according to 
clinical stages of HIV infection with higher scores for asymptomatic HIV patients and lower scores at 
AIDS stage (p<0.001), except for spirituality domain (p > 0.05). 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/AIDS.
