چکیده
Clinical studies are giving increased importance to quality of life assessments as measures of the relative effectivenessof prevention and treatment programs used during pregnancy and antenatally.Objectives: The aim of this study was to validate the Quality of life gravidarum (QOL-GRAV) questionnaire for Iranianwomenduringthe pregnant periodPatients and Methods: In this cross-sectional methodological study, content validity following back and forward translation wasassessed by a panel of experts. Using the two-stage cluster sampling method, 565 pregnant women referred to health care centersfrom April to June 2015 in Tabriz, Iran were enrolled in the study. Construct validity by assessing the factor structure, and convergentand discriminant validity were evaluated using scale-item correlations and known group analyses. Internal consistency andtest–retest reliability were assessed in a sample of 30 pregnant women by the Cronbach’s coefficient and intra-class correlationcoefficient (ICC).Results: The QOL-GRAV showed good content validity (CVI value = 0.95 and CVR value = 1), internal consistency ( = 0.79), andtest–retest reliability (ICC = 0.86). The results of the CFA for two-factor models indicate an acceptable fit of the proposed model(RMSEA; 90% CI = 0.083; 0.068–0.099, CFI = 0.95, GFI = 0.96, and AGFI = 0.92).Conclusions: The findings support the validity and reliability of the Iranian version of the QOL-GRAV questionnaire. Therefore, it isrecommended to be used for both clinical and research purposes.
