Bottom Line: The facet-domain correlations were all statistically significant (p<0.001).There was a correlation between the domains from the WHOQOL-HIV and SF-36 questionnaires, with coefficients ranging from 0.349 to 0.763 (p<0.05 for all), except for the Spirituality domain.The test-retest reliability was suitable for all domains and facets, with statistically significant intra-class coefficients between 0.615 and 0.931.

ABSTRACT

Purpose: Quality of life is a key element in the follow-up of people living with HIV/AIDS. The main purpose of this study was to validate the French version of the WHOQOL-HIV instrument by comparing this instrument to a generic questionnaire. The second objective was to test the reproducibility of this questionnaire.

Method: The WHOQOL-HIV and SF-36 questionnaires were filled out by 50 patients on two separate occasions with a time interval of 2 weeks. The internal consistency, validity and reliability of the WHOQOL-HIV were evaluated.

Results: The internal consistency was acceptable for the different domains, with Cronbach's alpha ranging from 0.937 to 0.944. The facet-domain correlations were all statistically significant (p<0.001). There was a correlation between the domains from the WHOQOL-HIV and SF-36 questionnaires, with coefficients ranging from 0.349 to 0.763 (p<0.05 for all), except for the Spirituality domain. The test-retest reliability was suitable for all domains and facets, with statistically significant intra-class coefficients between 0.615 and 0.931.

Conclusion: This study demonstrated that the French translation of the WHOQOL-HIV instrument is a valid and reproducible tool for the evaluation of the quality of life for HIV-infected patients.

pone-0073180-g001: Relationship between scores of domains for test-retest WHOQOL-HIV.

Mentions: The test-retest reliability contained statistically significant intra-class coefficients for all of the domains and facets (Table 4) (Figure 1). The Bland Altman method revealed a difference between the measurement days for the domains (−0.015 to 0.795) and the facets (−0.110 to 0.260). All of the differences were included between the limits of agreement. Finally, the effect size was small for all of the items and domains, varying from 0 to 0.36.
