The current study used novel methodology to characterize intraindividual variability in the experience of dynamic, within-person changes in postpartum depressive (PPD) symptoms across the first year postpartum and evaluated maternal and infant characteristics as predictors of between-person differences in intraindividual variability in PPD symptoms over time. With a sample of 322 low-income Mexican-origin mothers (Mage = 27.79; SD = 6.48), PPD symptoms were assessed at 11 time points from 3 weeks to 1 year postpartum (Edinburgh Perinatal Depression Scale; Cox & Holden, 2003). A prenatal cumulative risk index was calculated from individual psychosocial risk factors. Infant temperamental negativity was assessed via a maternal report at the infant age of 6 weeks (Infant Behavior Questionnaire; Putnam et al., 2014). Multilevel location scale analyses in a dynamic structural equation modeling (Asparouhov et al., 2018) framework were conducted. Covariates included prenatal depressive symptoms. On average, within-mother change in depressive symptoms at one time point was found to carry over to the next time point. Nonnull within-mother volatility in PPD symptoms reflected substantial ebbs and flows in PPD symptoms over the first year postpartum. Results of the between-level model demonstrated that mothers differed in their equilibriums, carryover, and volatility of their PPD symptoms. Mothers with more negative infants and those with higher prenatal cumulative risk exhibited higher equilibriums of PPD symptoms and more volatility in symptoms but did not differ in their carryover of PPD symptoms.

对产后第一年抑郁症状的动态视角。


本研究使用新颖的方法来描述产后第一年产后抑郁（PPD）症状的动态、人内变化经历的个体差异，并评估母婴特征作为 PPD 个体差异的预测因素随着时间的推移出现症状。以 322 名低收入墨西哥裔母亲为样本（Mage = 27.79；SD = 6.48），在产后 3 周至 1 年的 11 个时间点评估 PPD 症状（爱丁堡围产期抑郁量表；Cox & Holden，2003）。产前累积风险指数是根据个体心理社会风险因素计算得出的。通过婴儿 6 周大时的母亲报告评估婴儿气质消极性（婴儿行为问卷；Putnam 等，2014）。在动态结构方程模型（Asparouhov 等，2018）框架中进行了多级位置尺度分析。协变量包括产前抑郁症状。平均而言，一个时间点母亲内部抑郁症状的变化会延续到下一个时间点。 PPD 症状的母亲内部非零波动反映了产后第一年 PPD 症状的大幅波动。水平间模型的结果表明，母亲们的产后抑郁症症状的平衡、遗留和波动性各不相同。拥有更多阴性婴儿的母亲和产前累积风险较高的母亲表现出更高的 PPD 症状平衡和更大的症状波动性，但在 PPD 症状的延续方面没有差异。 （PsycInfo 数据库记录 (c) 2023 APA，保留所有权利）。
