The Parenting Stress Index-Short Form (PSI-SF) has been widely employed to assess parenting stress in a number of research and clinical trials. To date, no parenting stress studies in Japan have examined the factor structure, validity, and reliability of the PSI-SF. Therefore, this study aimed to evaluate the psychometric properties of this 19-item version as administered in a national cohort study, the Japan Environment and Children's Study, to two sample groups of mothers, those with a 1.5-year-old child and those with a 2.5-year-old child (n = 79,282 and 75,831, respectively). We performed exploratory factor analysis to re-examine the appropriate factor structure, confirmatory factor analysis to evaluate goodness of fit, and calculated Cronbach's α and Pearson's r coefficients to evaluate internal consistency and reproducibility over time, respectively. The results highlighted that a three-factor structure fit the instrument better than a two-factor structure, yielding better scores for the model fit indices and the α and r coefficients. In addition, the third factor identified in this study was strongly associated with having a relationship with and help from the husband. The findings suggest the importance of using a parenting stress scale with various factors to evaluate mothers' parenting stress.
父母压力指数-短式（PSI-SF）已被广泛应用于多项研究和临床试验中，以评估父母压力。迄今为止，在日本尚无研究检验 PSI-SF 的因子结构、有效性和可靠性。因此，本研究旨在评估该 19 项版本在全国性队列研究——日本环境与儿童研究中的心理测量特性，该研究的两个样本组为 1.5 岁儿童的母亲和 2.5 岁儿童的母亲（n=79282 和 75831）。我们进行了探索性因子分析，以重新检验合适的因子结构，进行验证性因子分析以评估拟合优度，并计算克朗巴赫α系数和皮尔逊 r 系数，以分别评估内部一致性和随时间的可重复性。结果表明，三因子结构比两因子结构更适合该工具，模型拟合指数以及α和 r 系数的得分更好。此外，本研究中确定的第三个因子与与丈夫的关系和获得丈夫的帮助密切相关。研究结果表明，使用具有多种因素的父母压力量表评估母亲的父母压力非常重要。
