Abstract

Background: Cerebral palsy is the most prevalent physical disability in children, with significant implications for motor function and quality of life. Reliable caregiver-reported outcome measures are important for evaluating function in everyday life. The Gross Motor Function–Family Report is a validated tool designed to measure outcomes, but no Urdu version existed to serve Pakistani populations. Objective: This study aimed to develop an Urdu version of the GMF-FR and evaluate its reliability and validity for assessing gross motor function in children with Cerebral palsy. Methods: A cross-sectional study was conducted in Faisalabad, Pakistan, involving 50 children aged 2–14 years with diagnosed Cerebral palsy. The Gross Motor Function–Family Report was translated into Urdu following Beaton’s cross-cultural adaptation guidelines. Internal consistency was assessed using Cronbach’s alpha; test-retest reliability was evaluated via intraclass correlation coefficients. Validity was assessed through construct validity (Spearman’s rho with GMFCS) and discriminant validity (Kruskal-Wallis test across GMFCS levels). Results: The Urdu Gross Motor Function–Family Report showed excellent internal consistency (Cronbach’s alpha = 0.947) and strong test-retest reliability (ICC = 0.999). Construct validity gave a strong negative correlation with GMFCS levels (ρ = -0.857, p < 0.001), and discriminant validity confirmed statistically significant differences across GMFCS levels (p < 0.001). High rates of caregiver agreement supported face validity. Conclusion: The Urdu version of the Gross Motor Function–Family Report is a reliable and valid tool for assessing gross motor function in children with Cerebral palsy patients in Urdu-speaking populations. It enables culturally relevant, family-centered assessments that support individualized rehabilitation planning in resource-limited settings.
