To study the impacts of maternal depressive symptoms trajectories and harsh parenting and explore if the maternal quality of life (QoL) mediates this association.
We used data from the 2004 Pelotas Birth Cohort, a population-based longitudinal study from Pelotas, Brazil (n=3,285 mothers, complete cases analysis). We used the Edinburgh Postnatal Depression Scale (EPDS) to assess maternal depressive symptoms and calculated their trajectories from 3 months until the 11-year follow-up using a group-based modeling approach. Psychological and physical aggression were measured using the Parent-Child Conflict Tactics Scale (CTSPC). Maternal QoL was measured by the question "How is your quality of life?" Data were analyzed using path models in Mplus.
All maternal depressive symptoms trajectories increased the frequency of psychological and physical aggression at early adolescence when compared to the reference group. Mediation analysis indicated that maternal depressive symptoms led to low levels of perceived maternal QoL, which in turn was associated with increased use of harsh parenting. The proportion of total effect explained by maternal QoL ranged from 4.04% (0.00-5.58%) to 16.31% (10.88-19.10%).
Our findings, within a longitudinal framework from a middle-income country, support existing evidence that maternal depressive symptoms are associated with harsh parenting. Our results also suggest that one mechanism underlying this association is lower perceived maternal QoL.
研究母亲抑郁症状轨迹和严厉育儿方式的影响，并探讨母亲生活质量（QoL）是否介导了这种关联。
我们使用了来自2004年佩洛塔斯出生队列的数据，这是一项基于巴西佩洛塔斯人群的纵向研究（n = 3285名母亲，采用完整病例分析）。我们使用爱丁堡产后抑郁量表（EPDS）评估母亲的抑郁症状，并使用基于群体的建模方法计算从3个月到11年随访期间的症状轨迹。使用亲子冲突策略量表（CTSPC）测量心理和身体攻击行为。母亲的生活质量通过“你的生活质量如何？”这一问题进行测量。数据在Mplus中使用路径模型进行分析。
与参照组相比，所有母亲抑郁症状轨迹在青春期早期都增加了心理和身体攻击行为的频率。中介分析表明，母亲的抑郁症状导致母亲对生活质量的感知水平较低，这反过来又与更多地使用严厉育儿方式相关。母亲生活质量所解释的总效应比例在4.04%（0.00 - 5.58%）至16.31%（10.88 - 19.10%）之间。
我们在一个中等收入国家的纵向框架内的研究结果支持了现有证据，即母亲抑郁症状与严厉育儿方式有关。我们的结果还表明，这种关联背后的一个机制是母亲对生活质量的较低感知。
