TRANSLATION AND PSYCHOMETRIC EVALUATION OF THE GUJARATI VERSION OF THE GLOBAL PHYSICAL ACTIVITY QUESTIONNAIRE (GPAQ)

##article.abstract##

Background: The Global Physical Activity Questionnaire (GPAQ) is an internationally recognized tool for measuring physical activity, but until now, no validated Gujarati version existed. Objective: This study aimed to translate the GPAQ into Gujarati, culturally adapt it, and assess its validity and reliability among Gujarati-speaking adults. Methods: Using standard translation and cultural adaptation guidelines, the GPAQ was translated into Gujarati through a multi-step process involving forward and backward translation, expert review, and pilot testing. Face and content validity were evaluated by professionals in the field. The Gujarati GPAQ was then administered to 30 adult participants from Ahmedabad, Gujarat, who completed both the Gujarati and the original English versions. Internal consistency, test–retest reliability, and concurrent validity were statistically assessed. Results: The translation process produced a clear, culturally appropriate Gujarati GPAQ. Expert reviewers confirmed strong face and content validity. Internal consistency was excellent (Cronbach’s alpha 0.991–0.999), and test–retest reliability was also high (ICC 0.991–0.999). Scores from the Gujarati version closely matched those from the English version (correlation coefficients 0.979–0.997, p < 0.001). Most participants were classified as highly physically active. Conclusion: The Gujarati version of the GPAQ is a reliable and valid instrument for assessing physical activity among Gujarati-speaking adults. Its use will help researchers and public health professionals gather accurate physical activity data in this population.
