目的：(国际)国家监测系统和比较需要评估体力活动的工具。方法：从9个国家不同的社会文化、教育和经济背景招募男性和女性成年人(总计2657人)。GPAQ和国际体力活动问卷(IPAQ)至少进行2次测试。8个国家使用客观测量(计步器或加速度计)在7天内评估了标准的有效性。结果：信度系数为中等到实质性(Kappa 0.67~0.73；Spearman‘s Rho 0.67~0.81)。IPAQ和GPAQ的同时效度也显示出中等到高度的正相关(范围为0.45~0.65)。效标效度结果处于较差的中等值(0.06~0.35)。观察到性别、教育程度、体重指数和城乡之间以及国家之间存在一些差异。结论：总体而言，GPAQ提供了可重复性的数据，并与iPAQ呈中等-强烈的正相关，iPAQ是先前验证和接受的体力活动衡量标准。GPAQ的验证结果很差，尽管其大小与其他研究报告的范围相似。总体而言，这些结果表明，GPAQ是在人口健康监测系统中监测体力活动的合适和可接受的工具，尽管有必要在其他国家进一步复制这项工作。
Purpose: Instruments to assess physical activity are needed for (inter)national surveillance systems and comparison. Methods: 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. Results: 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. Conclusions: 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.
