Women’s postpartum depression is the most common mental illness following childbirth. In the present study, we aimed to examine the association between intimacy and postnatal depression and to explain it through the mediating role of maternal self-efficacy. We also aimed to explore if the partner’s job stress moderates the proposed mediation model. Between November 1 and December 31, 2019, a sample of 85 couples of first-time parents, having a child aged 1–12 months, participated in this non-experimental cross-sectional study. Mothers completed measures of intimacy, maternal self-efficacy, postpartum depression, and religiosity, while fathers completed scales of job stress and religiosity. The results indicated that: (1) intimacy is negatively associated with postpartum depression, the regression analyses confirming that greater intimacy predicts lower levels of postpartum depression; (2) maternal self-efficacy partially mediates the relationship between intimacy and postpartum depression, (3) partner’s job stress moderates the link between intimacy and maternal self-efficacy, and (4) maternal religiosity and partner’s religiosity represent significative covariates of the moderated mediation model. The findings suggest that therapists should pay close attention to intimacy and variables that mediate and moderate its relationship with postnatal depression, maternal self-efficacy and partner’s job stress, to improve first-time mothers’ mental health.

女性产后抑郁症是分娩后最常见的精神疾病。在本研究中，我们旨在检验亲密关系与产后抑郁症之间的关系，并通过母亲自我效能感的中介作用来解释它。我们还旨在探索合作伙伴的工作压力是否会缓和建议的调解模型。在 2019 年 11 月 1 日至 12 月 31 日期间，85 对首次为人父母的夫妇的样本，他们有一个 1-12 个月的孩子，参与了这项非实验性横断面研究。母亲完成了亲密关系、母亲自我效能感、产后抑郁和宗教信仰的测量，而父亲完成了工作压力和宗教信仰的量表。结果表明：（1）亲密度与产后抑郁呈负相关，回归分析证实，亲密程度越高，产后抑郁程度越低；(2) 母亲的自我效能感在亲密关系和产后抑郁之间起部分中介作用，(3) 伴侣的工作压力调节了亲密感和母亲自我效能感之间的联系，(4) 母亲的宗教信仰和伴侣的宗教信仰是有调节的中介的显着协变量模型。研究结果表明，治疗师应密切关注与产后抑郁、母亲自我效能感和伴侣工作压力之间的关系和调节亲密关系的变量，以改善初为人母的心理健康。(3) 伴侣的工作压力调节了亲密关系和母亲自我效能之间的联系，(4) 母亲的宗教信仰和伴侣的宗教信仰代表了有调节的中介模型的显着协变量。研究结果表明，治疗师应密切关注与产后抑郁、母亲自我效能感和伴侣工作压力之间的关系和调节亲密关系的变量，以改善初为人母的心理健康。(3) 伴侣的工作压力调节了亲密关系和母亲自我效能之间的联系，(4) 母亲的宗教信仰和伴侣的宗教信仰代表了有调节的中介模型的显着协变量。研究结果表明，治疗师应密切关注与产后抑郁、母亲自我效能感和伴侣工作压力之间的关系和调节亲密关系的变量，以改善初为人母的心理健康。
