This study aimed to assess the reliability and concurrent validity of the Bahasa Melayu version of the Global Physical Activity Questionnaire (GPAQ-M) by comparing it with the short form of the International Physical Activity Questionnaire (IPAQ-S) and objectively measuring physical activity using a Yamax DigiWalker (Yamax, Tokyo, Japan) pedometer. A total of 100 adults aged between 20 and 58 years from Kelantan in Malaysia voluntarily participated in this study. The Wilcoxon signed-rank analysis showed no significant differences in 2-week test–retest scores for total metabolic equivalent•minutes•per week and 4 domains of the GPAQ-M. There was a low but significant relationship between time spent on total physical activity measured by the GPAQ-M and average steps per day recorded using the pedometer (r_s = .265, P = .013). Significant correlations were also found between GPAQ-M and the IPAQ-S for varying levels of intensity during physical activities (r_s = .309-.466, P < .01).
