The present study aimed to examine intra- and interpersonal associations between poor mental health and mother–daughter relationship closeness in a sample of 467 dyads. An Actor–Partner Interdependence Model was utilized to examine bidirectional processes between mothers (mean age = 42.64, SD = 6.5) and their adolescent daughters (mean age = 15.37, SD = 1.15). The independent variable was self-reported poor mental health and the dependent variable was relationship closeness. Additionally, communication satisfaction was examined as a potential interpersonal mediator of the pathway between poor mental health and relationship closeness. Daughters’ self-reported poor mental health negatively predicted their own perception of closeness as well as mothers’ perception of closeness. Additionally, we find evidence that perceived communication may explain (i.e., mediate) both the actor effect (one’s own poor mental health on one’s own perception of closeness) and the partner effect (partner’s poor mental health on one’s own perception of closeness). Our results suggest that when daughters’ mental health is poor, relationship closeness as perceived by mother and daughter may be weakened, and that this effect may in part be explained by poor communication between mother and daughter. Strategies to promote family communication, especially for families experiencing mental health problems, may aid in the development of closer mother–daughter relationships. Further, our results suggest the importance of investigating the potential bidirectional influence of mothers’ and daughters’ mental health on parent-adolescent relationship quality within a dyadic unit.

本研究的目的是在467个二元组样本中检查精神健康状况差与母女关系亲密性之间的人际和人际关系。使用了一个演员-伙伴相互依存模型来检查母亲（平均年龄= 42.64，SD = 6.5）和青春期女儿（平均年龄= 15.37，SD = 1.15）之间的双向过程。自变量是自我报告的心理健康状况不佳，因变量是亲密关系。此外，沟通满意度被认为是不良心理健康与亲密关系之间潜在的人际关系中介。女儿自我报告的精神健康状况较差，预示着自己对亲密感的感知以及母亲对亲密感的感知。另外，我们发现有证据表明，感知的交流可以解释（即调解）行为者效应（一个人对自己的亲密感的不良心理健康）和伴侣效应（伙伴对一个人的亲密感的不良心理健康）。我们的结果表明，当女儿的心理健康状况较差时，母女之间的亲密关系可能会减弱，并且这种影响可能部分是由母女之间的沟通不畅所致。促进家庭沟通的战略，特别是对于那些患有精神健康问题的家庭，可能有助于建立更紧密的母女关系。进一步，
