ABSTRACT
The aim of this cross-sectional study was to validate the first Persian version of the WHOQOL-HIV BREF questionnaire. The study sample comprised 61 patients regularly attending the outpatient infectious disease clinic consultation centre for patients with behavioural disorders in 2013-2014. The internal consistency, content related validity and reliability of WHOQOL-HIV BREF were evaluated. Content validity was quantified using the content validity ratio (CVR) according the to Lawshe formula. CVR > 0.51 and mean judgment > 2 were significant at P = 0.05. The Cronbach alpha score was > 0.7 for each domain and = 0.87 for the whole scale, indicating good reliability. Item-to-total correlation coefficient between each item and its respective domain was 0.39-0.87. The correlation between each domain and overall QOL was excellent. This study demonstrates that the Persian version of WHOQOL-HIV BREF is a valid and reliable tool for evaluation of QOL in HIV-infected patients.

The aim of this cross-sectional study was to validate the first Persian version of the WHOQOL-HIV BREF questionnaire. The study sample comprised 61 patients regularly attending the outpatient infectious disease clinic consultation centre for patients with behavioural disorders in 2013-2014. The internal consistency, content related validity and reliability of WHOQOL-HIV BREF were evaluated. Content validity was quantified using the content validity ratio [CVR] according the to Lawshe formula. CVR > 0.51 and mean judgment > 2 were significant at P = 0.05.

La présente étude transversale avait pour objectif de valider la première version en langue perse du questionnaire Qualité de vie et VIH - WHOQOL-HIV BREF. L'échantillon de l'étude comprenait 61 patients qui consultaient régulièrement au centre de consultations externes spécialisé dans le traitement des maladies infectieuses pour les patients ayant des troubles comportementaux en 2013-2014. La cohérence interne, la validité de contenu et la fiabilité du questionnaire WHOQOL-HIV BREF ont été évaluées. La validité de contenu a été quantifiée au moyen du ratio de validité de contenu à partir de la formule de Lawshe. Un ratio de validité de contenu supérieur à 0,51 et un jugement moyen supérieur à 2 étaient significatifs à p = 0,05. L'alpha de Cronbach pour tous les domaines était supérieur à 0,7 et égal à 0,87 pour l'ensemble de l'échelle, ce qui indique une bonne fiabilité. Le coefficient de corrélation de l'item avec le score total entre chaque item et son domaine respectif était compris entre 0,39 et 0,87. La corrélation entre chaque domaine et la qualité de vie globale était excellente. La présente étude montre que la version en langue perse du questionnaire WHOQOL-HIV BREF est valable et constitue un outil fiable pour l'évaluation de la qualité de vie chez les patients infectés par le VIH
