Self-reported parental stress was investigated in three samples of mothers with small children, using a Swedish version of the Parenting Stress Index (PSI). Dimensionality in experienced stress using items from six PSI Parent Domain subscales and eight new items was examined in factor analyses of data from a nationwide representative sample. Cross-validation proved the chosen factor pattern to be stable. Based on an oblique 5-factor solution new subscales were constructed. A second order factor analysis indicated influence from a higher order factor, seen as a general parental stress construct. High alpha coefficients revealed that homogeneous subscales had been formed. Test-retest correlations indicated good stability over a mean time period of 30 days. Influences from maternal background variables were found, but no relation to child age or gender. Global estimates of parental stress, reported child problems, mothers' scoring on the Edinburgh Postnatal Depression Scale and two measures of social support all correlated significantly with overall parental stress, and with some subscales. The justification of the subscale approach to parental stress was discussed. It was concluded that the PSI in its present form could be used as a reliable and valid instrument for measuring experienced parental stress in mothers of young children.
使用瑞典版的《育儿压力指数》（PSI），对有幼儿的母亲的三个样本进行了自我报告的父母压力调查。在对来自全国代表性样本的数据进行因子分析时，使用六个PSI父母领域子量表的项目和八个新项目来检验经历压力的维度。交叉验证证明所选的因子模式是稳定的。基于斜交五因子解构建了新的子量表。二阶因子分析表明存在一个高阶因子的影响，该高阶因子被视为一般的父母压力结构。高阿尔法系数表明已形成了同质的子量表。重测相关性表明在平均30天的时间段内具有良好的稳定性。发现了母亲背景变量的影响，但与孩子的年龄或性别无关。父母压力的总体估计、报告的孩子问题、母亲在爱丁堡产后抑郁量表上的得分以及两种社会支持测量方法均与总体父母压力以及一些子量表显著相关。讨论了采用子量表方法测量父母压力的合理性。得出的结论是，当前形式的PSI可作为测量幼儿母亲经历的父母压力的可靠且有效的工具。
