Translation and validation of the Pelvic Girdle Questionnaire in the Urdu language

Introduction and hypothesisThe Pelvic Girdle Questionnaire (PGQ) is designed to determine pain and limited activities in pregnant and postpartum women with pelvic girdle pain (PGP). The purpose of this study was to translate the PGQ into the Urdu language and find out the cross-cultural validity and reliability of the Urdu PGQ among pregnant and postpartum women.MethodsA translation and cultural adaptation study was performed following international guidelines. The PGQ (the Urdu version) was drafted and a pilot study was conducted on 16 pregnant and postpartum women. A total of 125 pregnant and postpartum females participated in this study for validity and test-retest reliability. SPSS 25 was used for data analysis.ResultsContent validity was analyzed by the content validity index ranging from (0.92 to 1). Convergent validity was determined by correlating the Urdu version of the PGQ with the Oswestry Disability Index (ODI). Pearson rank correlation coefficient between the PGQ and the ODI (p=0.84) showed convergent validity. Internal consistency and test-retest reliability of the Urdu version of the PGQ were calculated by Cronbach's alpha (alpha=0.98), and intra-class correlation coefficient (ICC=0.98) respectively.ConclusionThe Urdu version of the PGQ showed good content and convergent validity as well as high internal consistency and test-retest reliability.
