The International Physical Activity Questionnaire (IPAQ) was developed to assess the physical activity patterns in populations. The authors aim to examine the reliability and validity of the Malay version of IPAQ (IPAQ-M). The IPAQ-M was self-administered twice at a 1-week interval to assess its test–retest reliability. Criterion validity was assessed between the IPAQ-M and a 7-day physical activity log (PA-Log). A total of 81 Malay adults participated in the study. Intraclass correlation coefficients (ICC), kappa (κ), correlation coefficients (ρ), and Bland–Altman plot were used for data analyses. The ICC scores revealed moderate to good correlations (ICC = 0.54-0.92; P < .001) on items categorized by intensities and domains and a κ of 0.73 for total activity. Validity results from the PA-Log were statistically significant (P < .001) across intensities and domains (ρ = 0.67-0.98). The IPAQ-M demonstrated good reliability and validity for the evaluation of physical activity among this Malay population.
