Sleep quality among college students is affected by numerous factors. Previous studies have linked sleep quality to family dynamics as well as personality. However, little is known about the mechanisms underlying this relationship. The aim of this study is to incorporate a moderated mediation model to explore the big five personality traits in mediating the relationship between family dynamics and sleep quality and whether this indirect relationship is modified by only-child status among Chinese undergraduate students. Survey data were collected from a cross-sectional study conducted in Shandong, China and 1022 undergraduate students aged 18-24 were recruited. The mediation and moderated mediation modeling analyses were carried out with the software SPSS PROCESS macro. After controlling for gender and grade, mediation analysis indicated that conscientiousness and agreeableness of the big five personality traits partially mediated the link between family dynamics and sleep quality (β = -0.0093, CI: -0.0178, -0.0018; β = -0.0047, CI: -0.0084, -0.0013), and moderation analysis found only-child status acted as a moderator in the relationship between family dynamics and the agreeableness of the big five personality traits (only child, β = -0.0129, CI: -0.0196, -0.0072; non-only-child, β = -0.0040, CI: -0.0078, -0.0002). Results showed that family dynamics positively predicted sleep quality both directly and indirectly via the conscientiousness and agreeableness of big five personality traits. Only-child status moderated the indirect association between family dynamics and agreeableness of big five personality traits. The current study advanced our understanding of the mechanism underlying the connection between family dynamics and sleep quality and helped to develop intervention measures to improve sleep quality of college students.
大学生的睡眠质量受到许多因素的影响。先前的研究已经将睡眠质量与家庭动态以及个性联系起来。然而，对于这种关系的潜在机制知之甚少。本研究旨在纳入一个调节中介模型，以探索大五人格特质在调节家庭动态与睡眠质量之间的关系中的作用，以及这种间接关系是否会因中国本科大学生的独生子女身份而发生变化。本研究采用横断面研究方法，在山东进行了调查，共招募了 1022 名 18-24 岁的本科生。使用 SPSS PROCESS 宏进行了中介和调节中介模型分析。在控制了性别和年级后，中介分析表明，大五人格特质中的责任心和宜人性部分中介了家庭动态与睡眠质量之间的关系（β=-0.0093，CI：-0.0178，-0.0018；β=-0.0047，CI：-0.0084，-0.0013），而调节分析发现独生子女身份在家庭动态与大五人格特质的宜人性之间的关系中起调节作用（独生子女，β=-0.0129，CI：-0.0196，-0.0072；非独生子女，β=-0.0040，CI：-0.0078，-0.0002）。结果表明，家庭动态既可以直接又可以通过大五人格特质中的责任心和宜人性间接正向预测睡眠质量。独生子女身份调节了家庭动态与大五人格特质的宜人性之间的间接关系。本研究增进了我们对家庭动态与睡眠质量之间关系的潜在机制的理解，并有助于制定干预措施来改善大学生的睡眠质量。
