feasibility, reliability, and validity of the iranian version of the quality of life questionnaire for pregnancy

conclusions the findings support the validity and reliability of the iranian version of the qol-grav questionnaire. therefore, it is recommended to be used for both clinical and research purposes. results the qol-grav showed good content validity (cvi value = 0.95 and cvr value = 1), internal consistency (α = 0.79), and test–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). objectives the aim of this study was to validate the quality of life gravidarum (qol-grav) questionnaire for iranian women during the pregnant period patients and methods in this cross-sectional methodological study, content validity following back and forward translation was assessed by a panel of experts. using the two-stage cluster sampling method, 565 pregnant women referred to health care centers from april to june 2015 in tabriz, iran were enrolled in the study. construct validity by assessing the factor structure, and convergent and discriminant validity were evaluated using scale-item correlations and known group analyses. internal consistency and test–retest reliability were assessed in a sample of 30 pregnant women by the cronbach’s α coefficient and intra-class correlation coefficient (icc). background clinical studies are giving increased importance to quality of life assessments as measures of the relative effectiveness of prevention and treatment programs used during pregnancy and antenatally.
