Instruments to assess physical activity are needed for (inter)national surveillance systems and comparison.
Male and female adults were recruited from diverse sociocultural, educational and economic backgrounds in 9 countries (total n = 2657). GPAQ and the International Physical Activity Questionnaire (IPAQ) were administered on at least 2 occasions. Eight countries assessed criterion validity using an objective measure (pedometer or accelerometer) over 7 days.
Reliability coefficients were of moderate to substantial strength (Kappa 0.67 to 0.73; Spearman's rho 0.67 to 0.81). Results on concurrent validity between IPAQ and GPAQ also showed a moderate to strong positive relationship (range 0.45 to 0.65). Results on criterion validity were in the poor-fair (range 0.06 to 0.35). There were some observed differences between sex, education, BMI and urban/rural and between countries.
Overall GPAQ provides reproducible data and showed a moderate-strong positive correlation with IPAQ, a previously validated and accepted measure of physical activity. Validation of GPAQ produced poor results although the magnitude was similar to the range reported in other studies. Overall, these results indicate that GPAQ is a suitable and acceptable instrument for monitoring physical activity in population health surveillance systems, although further replication of this work in other countries is warranted.
需要评估身体活动的工具来进行（国际）监测系统和比较。
从 9 个国家（共 2657 人）的不同社会文化、教育和经济背景中招募男性和女性成年人。使用 GPAQ 和国际体力活动问卷（IPAQ）至少进行两次评估。8 个国家使用客观测量（计步器或加速度计）在 7 天内评估了标准效度。
可靠性系数具有中等至较大的强度（Kappa 0.67 至 0.73；Spearman's rho 0.67 至 0.81）。关于 IPAQ 和 GPAQ 之间的同时有效性的结果也显示出中等至强的正相关关系（范围为 0.45 至 0.65）。标准效度的结果为较差至一般（范围为 0.06 至 0.35）。在性别、教育、BMI 和城乡之间以及国家之间观察到一些差异。
总体而言，GPAQ 提供了可重复的数据，并与 IPAQ 显示出中度至强的正相关，IPAQ 是一种先前验证和接受的身体活动衡量标准。尽管 GPAQ 的验证结果较差，但与其他研究报告的范围相似。总体而言，这些结果表明 GPAQ 是监测人口健康监测系统中身体活动的合适和可接受的工具，尽管在其他国家进一步复制这项工作是必要的。
