Evaluating the Responsiveness of Hindi version of International Physical Activity Questionnaire-Long Form (IPAQ-LF) in healthy adults.

Abstract

IPAQ-LF is widely used tool for subjective assessment of physical activity. It has been translated, cross culturally adapted into Hindi language and tested for its reliability and validity. However, Hindi version of this questionnaire is not evaluated for its responsiveness. The current study aims to evaluate the responsiveness of Hindi version of International Physical Activity Questionnaire-Long Form (IPAQ-LF) in healthy adults. The responsiveness was assessed in 60 healthy adults by administering 6-week pedometer-based programme and behavioral modification. Responsiveness statistics suggested that Hindi version of IPAQ-LF was responsive to change based on internal responsiveness statistics. The values calculated for Effect size I, Effect size II (SRM) and Effect size III were 0.223, 0.618, 0.631 respectively, suggesting small to moderate effect size. Also, the MCID calculated in the current study for healthy individuals was 1425.06 MET-mins/week. The study demonstrates that Hindi version of IPAQ-LF is a responsive tool for assessing physical activity levels for Hindi speaking population.
