Physical activity is considered an essential part of healthy life style for all population including kidney transplant recipients. The International Physical Activity Questionnaires (IPAQ) is internationally accepted self-reported screening tool for assessment of physical activity. However, till date Gujarati and Hindi version of IPAQ is not validated for Indian kidney transplant recipients. Aim: To validate the Gujarati and Hindi translated version of IPAQ long form in Indian kidney transplant recipients. Method: Original English version of IPAQ-long form was translated in Gujarati and Hindi language and evaluated for face, construct, concurrent validity and test retest reliability among Gujarati and Hindi transplant recipients. Result: 4 questions out of 27 were modified with 80% consensus of panelist to achieve face validity of both version of questionnaire. Total physical activity score of Gujarati (r=0.83) and Hindi (r=0.72) version were positively correlated with 6MWD in male transplant patients suggesting accepted construct validity. There was high positive correlation noted between all component of English, Gujarati and Hindi version (r>0.8, p<0.05) having good concurrent validity and acceptable test retest reliability. Conclusion: The modified Gujarati and Hindi version of IPAQ long form showed acceptable validity and reliability for the assessment of physical activity among kidney transplant recipients.
