Negativity in the family environment during the perinatal period is likely to have detrimental effects on maternal well-being, especially among low-income ethnic minority mothers who are at increased risk for experiencing postpartum depressive symptoms. With a sample of 322 Mexican and Mexican American families, this study used latent class growth analysis to identify meaningful subgroups of women based on their perceived family negativity reported prenatally and at 6, 12, 18, and 24 weeks postpartum. A 4-trajectory model of family negativity fit the data well: low-stable (58%), moderate-increasing (26%), high-decreasing (8%), and high-increasing (8%). Higher prenatal depressive symptomatology predicted membership in the moderate-increasing, high-decreasing, and high-increasing trajectories, relative to the low-stable trajectory. Findings suggest substantial heterogeneity in family negativity, identifying three significant growth patterns during the perinatal period with differential implications for maternal depressive symptomatology at 24 weeks and 12 months after delivery.

围产期家庭消极模式：对墨西哥裔妇女心理健康的影响。


围产期家庭环境的负面影响可能会对孕产妇的健康产生不利影响，尤其是低收入的少数族裔母亲，她们出现产后抑郁症状的风险更高。这项研究以 322 个墨西哥和墨西哥裔美国人家庭为样本，根据产前和产后 6、12、18 和 24 周报告的感知到的家庭消极情绪，使用潜在阶级增长分析来识别有意义的女性亚组。家庭消极性的 4 轨迹模型与数据吻合良好：低稳定（58%）、中度增加（26%）、高减少（8%）和高增加（8%）。相对于低稳定轨迹，较高的产前抑郁症状预测了中度增加、高减少和高增加轨迹的成员资格。研究结果表明，家庭消极情绪存在显着异质性，确定了围产期的三种显着生长模式，对产后 24 周和 12 个月的产妇抑郁症状具有不同的影响。 （PsycINFO 数据库记录 (c) 2020 APA，保留所有权利）。
