Validity and Reliability of Korean Version of International Physical Activity Questionnaire (IPAQ) Short Form

ABSTRACT

Background: This study was performed to evaluate the reliability and the validity of the Korean version of IPAQ short form. Method: Sixty-nine volunteer adults completed the questionnaires twice at 1 week interval, and the second one was compared to the results of Actical(R) in order to test validity. Results: The Korean version of IPAQ was accepted as a proper one by the IPAQ developers. Spearman Rho coefficients and Kappa values of test-retest reliability were 0.427~0.646 (median 0.542) and 0.365~0.620 (median 0.471), respectively. The Kappa values were above 0.4 in 5 out of 7 questionnaires. The more physically active by the short form questionnaire, the higher the measured value of the Actical(R) (P=0.039). Spearman Rho coefficient was 0.267 for the correlation between the results of the questionnaire and measured values by Actical(R). Conclusion: The reliability and the validity of the IPAQ short form were proven. Follow-up studies are needed.
