The postpartum period represents a major transition in the lives of many women, a time when women are at increased risk for the emergence of psychopathology including depression and PTSD. The current study aimed to better understand the unique contributions of clinically significant postpartum depression, PTSD, and comorbid PTSD/depression on mother-infant bonding and observed maternal parenting behaviors (i.e., behavioral sensitivity, negative affect, positive affect) at 6 months postpartum.
Mothers (n=164; oversampled for history of childhood maltreatment given parent study's focus on perinatal mental health in women with trauma histories) and infants participated in 6-month home visit during which dyads engaged in interactional tasks varying in level of difficulties. Mothers also reported on their childhood abuse histories, current depression/PTSD symptoms, and bonding with the infant using standardized and validated instruments.
Mothers with clinically significant depression had the most parenting impairment (self-report and observed). Mothers with clinically significant PTSD alone (due to interpersonal trauma that occurred predominately in childhood) showed similar interactive behaviors to those who were healthy controls or trauma-exposed but resilient (i.e., no postpartum psychopathology). Childhood maltreatment in the absence of postpartum psychopathology did not infer parenting risk.
Findings are limited by (1) small cell sizes per clinical group, limiting power, (2) sample size and sample demographics prohibited examination of third variables that might also impact parenting (e.g., income, education), (3) self-report of symptoms rather than use of psychiatric interviews.
Findings show that in the context of child abuse history and/or current PTSD, clinically significant maternal depression was the most salient factor during infancy that was associated with parenting impairment at this level of analysis.
产后时期是许多女性生活中的一个重大转变阶段,在此期间,女性出现包括抑郁症和创伤后应激障碍(PTSD)在内的精神病理学问题的风险增加。本研究旨在更好地理解具有临床意义的产后抑郁症、创伤后应激障碍以及创伤后应激障碍/抑郁症共病对母婴依恋以及产后6个月观察到的母亲养育行为(即行为敏感性、消极情绪、积极情绪)的独特影响。
母亲(n = 164;鉴于母研究关注有创伤史女性的围产期心理健康,对有童年虐待史的母亲进行了过度抽样)及其婴儿参与了产后6个月的家访,在此期间,母婴二人组进行了难度不同的互动任务。母亲们还使用标准化且经过验证的工具报告了她们的童年虐待史、当前的抑郁/创伤后应激障碍症状以及与婴儿的依恋情况。
患有具有临床意义抑郁症的母亲存在最严重的养育障碍(自我报告和观察所得)。仅患有具有临床意义创伤后应激障碍的母亲(由于人际创伤主要发生在童年时期)表现出与健康对照组或有创伤经历但恢复力强的母亲(即无产后精神病理学问题)相似的互动行为。在没有产后精神病理学问题的情况下,童年虐待并不会带来养育风险。
研究结果受到以下因素的限制:(1)每个临床组的样本量较小,限制了统计效力;(2)样本量和样本人口统计学特征使得无法检验可能也会影响养育的第三个变量(如收入、教育程度);(3)症状采用自我报告而非精神科访谈。
研究结果表明,在有儿童虐待史和/或当前患有创伤后应激障碍的背景下,在这一分析层面上,具有临床意义的母亲抑郁是婴儿期与养育障碍相关的最显著因素。
