This cross-sectional study examined the extent to which cumulative and specific dimensions-threat and deprivation-of adverse childhood experiences (ACEs) are associated with sleep quality in postpartum mothers. Eighty-seven mothers of infants completed assessments on sociodemographic characteristics, ACEs, and sleep quality. The sample was 39.1% White, 21.8% Latina, 16.1% Black/African American, 10.3% more than one race, 4.6% Asian, 4.6% American Indian/Alaskan Native, 2.4% unspecified race/ethnicity, and 1.1% Pacific Islander. An exploratory factor analysis was computed in which ACEs were categorized as dimensions of threat (i.e., experiencing harm or threat of harm) or deprivation (i.e., an absence of cognitive and social inputs). Separate generalized linear models were conducted to examine (a) cumulative ACEs and (b) threat and deprivation dimensions of ACEs in relation to maternal sleep quality scores on the Pittsburgh Sleep Quality Index (PSQI); higher PSQI scores indicate worse sleep quality. Likelihood ratio tests were conducted to compare if there were significant differences in model fit between the threat and deprivation model versus the cumulative ACEs model. Cumulative ACEs were positively associated with global PSQI scores. Threat, but not deprivation, was positively associated with global PSQI scores. The difference in variance explained between the two models was not statistically significant. The present study highlights the utility of dimensional models of adversity in conjunction with the cumulative ACEs model to identify more nuanced relationships between early adversity and maternal sleep outcomes. This approach may advance research on more targeted interventions during the postpartum period. (PsycInfo Database Record (c) 2025 APA, all rights reserved).
这项横断面研究考察了产后母亲童年期不良经历（ACEs）的累积维度和特定维度（威胁和剥夺）与睡眠质量之间的关联程度。87名婴儿母亲完成了关于社会人口学特征、ACEs和睡眠质量的评估。样本中白人占39.1%，拉丁裔占21.8%，黑人/非裔美国人占16.1%，多种族占10.3%，亚洲人占4.6%，美洲印第安人/阿拉斯加原住民占4.6%，未明确种族/族裔占2.4%，太平洋岛民占1.1%。进行了一项探索性因素分析，其中ACEs被分类为威胁维度（即经历伤害或伤害威胁）或剥夺维度（即缺乏认知和社会投入）。分别进行了广义线性模型分析，以检验（a）累积ACEs以及（b）ACEs的威胁和剥夺维度与匹兹堡睡眠质量指数（PSQI）上的母亲睡眠质量得分之间的关系；PSQI得分越高表明睡眠质量越差。进行似然比检验，以比较威胁和剥夺模型与累积ACEs模型之间在模型拟合上是否存在显著差异。累积ACEs与PSQI全球得分呈正相关。威胁而非剥夺与PSQI全球得分呈正相关。两个模型之间解释的方差差异无统计学意义。本研究强调了逆境维度模型与累积ACEs模型相结合在识别早期逆境与母亲睡眠结果之间更细微关系方面的效用。这种方法可能会推动产后时期更有针对性干预措施的研究。（PsycInfo数据库记录（c）2025美国心理学会，保留所有权利）
