To assess the psychometric properties of the Pregnancy Physical Activity Questionnaire (PPAQ) for women who read and speak Japanese.
This longitudinal study used a self-report questionnaire and quantitative biometric and instrumental measurements (actigraph) to assess the reliability and criterion validity.
A university hospital in Tokyo, Japan.
Sixty-nine pregnant women living in Tokyo and its suburbs were recruited.
The test-retest reliability of the Japanese version of the Pregnancy Physical Activity Questionnaire (PPAQ-J) was evaluated through intraclass correlation coefficients (ICCs) between PPAQ-J results administered three times (at recruitment, 7 and 14 days later). Criterion validity was assessed by comparing results to actigraph measures using Spearman's correlation coefficients. Participants wore the actigraph over the 2-week research period. Data from 58 participants were analyzed for test-retest reliability. The data of 54 participants were used to analyze criterion validity.
The ICCs for the first and second and for the first and third PPAQ-J questionnaires were ≥0.56 for total activity and activities broken down by intensity and type (in metabolic equivalents [METs] × hours/day). To evaluate criterion validity, Spearman's correlation coefficients were calculated between the first measurement of the PPAQ-J and three published cut-points used to classify actigraph data (minutes/day); correlations ranged from .02 to .35 for total activity, -.21 to -.25 for vigorous activity, -.09 to .38 for moderate activity, and .01 to .28 for light activity.
The PPAQ-J is a psychometrically sound and comprehensive measure of physical activity in pregnant Japanese women.
评估适用于读写日语女性的孕期身体活动问卷（PPAQ）的心理测量特性。
这项纵向研究使用了一份自我报告问卷以及定量生物特征和仪器测量（活动记录仪）来评估信度和效标效度。
日本东京的一家大学医院。
招募了69名居住在东京及其郊区的孕妇。
通过三次（招募时、7天后和14天后）进行的孕期身体活动问卷日语版（PPAQ-J）结果之间的组内相关系数（ICC）来评估PPAQ-J的重测信度。通过使用Spearman相关系数将结果与活动记录仪测量结果进行比较来评估效标效度。参与者在为期2周的研究期间佩戴活动记录仪。对58名参与者的数据进行重测信度分析。54名参与者的数据用于分析效标效度。
PPAQ-J问卷第一次与第二次以及第一次与第三次的ICC，对于总活动量以及按强度和类型划分的活动量（以代谢当量[METs]×小时/天计）均≥0.56。为评估效标效度，计算了PPAQ-J第一次测量结果与用于对活动记录仪数据进行分类的三个已发表切点（分钟/天）之间的Spearman相关系数；总活动量的相关系数范围为0.02至0.35，剧烈活动为-0.21至-0.25，中等活动为-0.09至0.38，轻度活动为0.01至0.28。
PPAQ-J是对日本孕期女性身体活动进行心理测量合理且全面的测量工具。
