目的：本研究的目的是使用荟萃分析的方法来检查收敛效度的国际体力活动问卷（IPAQ）设计：系统评价的荟萃分析。设置：相关研究进行了调查，从五个电子数据库。主要结果是IPAQ和其他工具之间的积差相关系数。对IPAQ的每个体力活动（PA）类别进行了5项单独的荟萃分析：步行、中度PA（MPA）、总中度PA（TMPA）、剧烈PA（VPA）和总PA（TPA）。计算每个PA类别不受统计伪影（即抽样误差和可靠性）影响的校正平均效应量（ES rho）。选定的调节变量为IPAQ的长度（即短格式和长格式），参考期（即最后7天和平常一周），给药方式（即采访者和自我报告），语言（即英文和译文）和文书受试者：从21项研究中检索了5个PA类别的152个ES rho。结果：结果显示小至中等大小的ES rho（0.27-0.49）。VPA中观察到最高值，而MPA中观察到最低值。的ES rho分化的一些主持变量跨PA categories.Conclusions：研究表明，IPAQ在每个PA类别的整体收敛效度。PA类别和调节变量之间的收敛效度程度的一些差异意味着，不同的研究条件下，应考虑使用适当类型的IPAQ之前，决定。
Objective: The purpose of the present study was to use a meta-analytic approach to examine the convergent validity of the International Physical Activity Questionnaire (IPAQ).Design: Systematic review by meta-analysis.Setting: The relevant studies were surveyed from five electronic databases. Primary outcomes of interest were the product-moment correlation coefficients between IPAQ and other instruments. Five separate meta-analyses were performed for each physical activity (PA) category of IPAQ: walking, moderate PA (MPA), total moderate PA (TMPA), vigorous PA (VPA) and total PA (TPA). The corrected mean effect size (ES rho) unaffected by statistical artefacts (i.e. sampling error and reliability) was calculated for each PA category. Selected moderator variables were length of IPAQ (i.e. short and long form), reference period (i.e. last 7 d and usual week), mode of administration (i.e. interviewer and self-reported), language (i.e. English and translated) and instruments (i.e. accelerometer, pedometer and subjective measure).Subjects: A total of 152 ES rho across five PA categories were retrieved from twenty-one studies.Results: The results showed small- to medium-sized ES rho (0.27-0.49). The highest value was observed in VPA while the lowest value was found in MPA. The ES rho were differentiated by some of the moderator variables across PA categories.Conclusions: The study shows the overall convergent validity of IPAQ within each PA category. Some differences in degree of convergent validity across PA categories and moderator variables imply that different research conditions should be taken into account prior to deciding on use of the appropriate type of IPAQ.
