  Title Validation of the French-Canadian Pelvic Girdle Questionnaire
Journal J Manipulative Physiol Ther. 2018 Mar-Apr;41(3):234-241
Peer Review Yes
Publication Type Article

Objective: Pain in the pelvic girdle area is commonly reported during pregnancy and the postpartum period, and its impact on quality of life is considerable. The Pelvic Girdle Questionnaire (PGQ), developed in 2011 in Norway, is the only condition-specific tool assessing pelvic girdle pain–related symptoms and disability. The questionnaire was recently translated and adapted for the French-Canadian population. The objective of this study was to assess the measurement properties of the previously translated French-Canadian PGQ.

Methods: Eighty-two women with pelvic girdle pain were included in this validation study. The French-Canadian PGQ, pain intensity Numeric Rating Scale, and Oswestry Disability Index were completed by participants at baseline, 48 hours later, and 3 to 6 months later to assess test-retest reliability, construct validity, responsiveness, floor and ceiling effects, and internal consistency.

Results: Reliability analyses indicated an intraclass correlation coefficient of 0.841 (95% confidence interval [CI] 0.750-0.901) for the global score. Construct validity analyses indicated a Spearman rank correlation coefficient of 0.696 with the Oswestry Disability Index. Responsiveness analyses identified an effect size of 0.908 (95% CI 0.434-1.644) and an area under the receiver operating characteristics curve of 0.823 (95% CI 0.692-0.953). There was no floor or ceiling effect, and internal consistency analyses indicated a Cronbach α of .933 for the activity subscale and .673 for the symptom subscale.

Conclusion: Overall, the French-Canadian version of the PGQ is reliable, valid, and responsive, suggesting that it can be implemented in both research and clinical settings to assess functional limitations in pregnant and postpartum women.
