Reliability and Validity of the Gujarati Version of the international physicalactivity Questionnaire-Short form (IPAQ-SF) in Gujarat

The International Physical Activity Questionnaire (IPAQ) is a widely used self-reported instrument for assessing physical activity across various intensities. This study aimed to culturally adapt and evaluate the reliability and validity of the Gujarati version of the IPAQ-Short Form (IPAQ-SF) for use within the Gujarati-speaking community. Following the IPAQ manual guidelines, the English version of the IPAQ-SF was translated into Gujarati using a forward-backward-forward translation process. To assess reliability, test-retest procedures were conducted, and the intraclass correlation coefficient (ICC) was calculated. Results showed strong test-retest reliability for the Gujarati IPAQ-SF, with an ICC average measure of 0.785 (95% CI: 0.537–0.899, p = 0.000), demonstrating significant consistency. The factorial validity of the Gujarati IPAQ-SF was also evaluated, confirming its effectiveness in measuring physical activity and sedentary behaviors. The findings indicate that the Gujarati IPAQ-SF is a reliable and valid tool for assessing vigorous physical activity and sedentary lifestyles in individuals aged 16–60. This culturally adapted version of the IPAQ-SF can be effectively utilized for physical activity assessments in the Gujarati-speaking population.
