Validity and reliability of Turkish version of the Recent Physical Activity Questionnaire

Purpose: Physical inactivity is an important determinant of chronic disease such as obesity, cardiovascular disease and certain types of cancer. Therefore, evaluation of physical activity becomes more important day by day. The purpose of the present study was to investigate the validity, reliability and Turkish version of The Recent Physical Activity Questionnaire (RPAQ) in healthy population. Materials and Methods: A total of 192 adults were included in the study. Standard "forward-backward" procedure used in translation of RPAQ. International Physical Activity Questionnaire-Long Form (IPAQ-LF) was used as the gold standard for the validity of RPAQ. It was re-adminestered on 50 participants one week interval for reliability of RPAQ analysis. Results: 122 (63.5%) were women, 70 (36.5%) were men of participants, and their mean age was 34.46 +/- 9.45 years. There was a high correlation between total score of IPAQ-LF and RPAQ (r: 0.747, p<0.001). When analysed validity for sub-scales, there was significant relationship between the subscales related to work and leisure activities while no significant relationship was found in scores for home and tranport domains. The test-retest reliability was showed that the Intraclass Correlation Coefficient (ICC) (between 0.978 and 1) were significant for RPAQ. Conclusion: RPAQ is a valid and reliable tool for measuring physical activity in Turkish people. The Turkish version of the RPAQ is a powerful measurement for assessing the physical activity levels of adult individuals.
