Background: International Physical Activity Questionnaire (IPAQ) is a reliable and valid tool that helps to measure physical activity of an individual.
Aim: To validate the Gujarati version of IPAQ to be used in clinical research on Gujarati population.
Settings and design: Cross sectional study conducted at Government Physiotherapy College, Jamnagar, Gujarat, India.
Materials and Method: IPAQ was translated into Gujarati from English using forward-backward-forward method. For face & content validity of Gujarati version group consensus method was used. Each question was examined by group of experts in field of Medicine, Physiology and Cardiopulmonary Physiotherapy. Each question was analysed for content, meaning, wording, format, ease of administration & scoring. Each question was scored by expert group as either accepted, rejected or accepted with modification. Procedure was continued until 80% of consensus for all items. Concurrent validity was found by comparing the English version of IPAQ with Gujarati version of IPAQ.
Statistical Analysis: Spearman’s correlation coefficients were used to assess the strength of association between the measures of both the versions.
Results: In validation process of Gujarati version of IPAQ total 21 questions were accepted; 6 questions were accepted with modification. High positive and significant correlations were also found for time spent in vigorous (ρ=0.83), moderate (ρ=0.74) and walking (ρ=0.93) activities between the IPAQ Gujarati and the original English version of IPAQ. Total physical activity was significantly and highly correlated (ρ = 0.90) between the IPAQ Gujarati and the original English version of IPAQ. The time spent in sitting was also significantly (ρ =0.94) and positively correlated between the IPAQ Gujarati and the original English version of IPAQ.
Conclusion: Gujarati version of International Physical Activity Questionnaire has a good validity to be used in Gujarati Population.
