Abstract

BACKGROUND

The Global Physical Activity Questionnaire (GPAQ) was developed as an improvement of the International Physical Activity Questionnaire (IPAQ) for use in cross-cultural settings. This study compared the reliability and validity of GPAQ and IPAQ in Vietnam.

METHODS

251 adults were randomly selected from a population-based survey (n = 1978) of noncommunicable disease risk factors. GPAQ and IPAQ were administered on 2 occasions. Participants wore pedometers and logged their physical activity (PA) for 7 consecutive days.

RESULTS

Test-retest correlations of GPAQ measurements differed for participants (n = 153) with stable work patterns (work PA r = .43, total PA r = .39) and those (n = 98) with unstable work patterns (work PA r = -0.02, total PA r = -0.05). IPAQ measurements did not differ in this way. GPAQ reliability was poorer for transport (GPAQ r = .25, IPAQ r = .60) and for leisure (GPAQ r = .21, IPAQ r = .45) PA. GPAQ estimates of total PA for participants with stable work patterns were moderately correlated with IPAQ total PA (r = .32), steps per day (r = .39), and PA log (r = .31).

CONCLUSIONS

The modifications made when designing GPAQ improved its reliability for persons with stable work patterns, but at the expense of poorer reliability for persons with more variable PA. GPAQ did not have superior validity to IPAQ.

摘要

背景

全球体力活动问卷（GPAQ）是为在跨文化环境中使用而对国际体力活动问卷（IPAQ）进行改进后开发的。本研究比较了 GPAQ 和 IPAQ 在越南的可靠性和有效性。

方法

从非传染性疾病危险因素的基于人群的调查（n=1978）中随机选择了 251 名成年人。在 2 次访视中分别进行 GPAQ 和 IPAQ 调查。参与者佩戴计步器并记录 7 天的体力活动（PA）情况。

结果

对于具有稳定工作模式的参与者（n=153），GPAQ 测量的重测相关性不同（工作 PA r=.43，总 PA r=.39），而对于具有不稳定工作模式的参与者（n=98），GPAQ 测量的重测相关性不同（工作 PA r= -0.02，总 PA r= -0.05）。IPAQ 测量没有这种差异。对于交通（GPAQ r=.25，IPAQ r=.60）和休闲（GPAQ r=.21，IPAQ r=.45）PA，GPAQ 的可靠性较差。对于具有稳定工作模式的参与者，GPAQ 对总 PA 的估计与 IPAQ 总 PA（r=.32）、每天的步数（r=.39）和 PA 日志（r=.31）中度相关。
