Abstract：
BACKGROUND: Previously, we demonstrated that childhood maltreatment could worsen depressive symptoms through neuroticism. On the one hand, some studies report that sleep disturbances are related to childhood maltreatment and neuroticism and worsens depressive symptoms. But, to our knowledge, no reports to date have shown the interrelatedness between childhood maltreatment, neuroticism, and depressive symptoms, and sleep disturbance in the one model. We hypothesized that sleep disturbance enhances the influence of maltreatment victimization in childhood or neuroticism on adulthood depressive symptoms and the mediation influence of neuroticism between maltreatment victimization in childhood and adulthood depressive symptoms.
METHODS: Total 584 Japanese volunteer adults recruited through convenience sampling from 4/2017 to 4/2018 were assessed regarding their characteristics of demographics, history of childhood maltreatment, sleep disturbance, neuroticism, and depressive symptoms with questionnaires self-administered. Survey data were analyzed using simple moderation models and a moderating mediation model.
RESULTS: The interaction of sleep disturbance with childhood maltreatment or neuroticism on depressive symptoms was significantly positive. Furthermore, the moderating effect of sleep disturbance on the indirect effect of childhood maltreatment to depressive symptoms through neuroticism was significantly positive.
CONCLUSIONS: Because this was a cross-sectional study, a causal relationship could not be confirmed.
CONCLUSIONS: Our findings indicate that individuals with milder sleep disturbance experience fewer depressive symptoms attributable to neuroticism and childhood maltreatment. Additionally, people with less sleep disturbance have fewer depressive symptoms arising from neuroticism owing to childhood maltreatment. Therefore, improvement of sleep disturbance will buffer the aggravating effect of childhood maltreatment, neuroticism caused by various factors, and neuroticism resulting from childhood maltreatment on depressive symptoms.

摘要：
背景：以前，我们证明，儿童虐待可以通过神经质使抑郁症状恶化。一方面,一些研究报告说，睡眠障碍与儿童虐待和神经质有关，并使抑郁症状恶化。但是,根据我们的知识，迄今为止，没有报告显示儿童虐待之间的相互关联性，神经质,和抑郁症状,和一个模型中的睡眠障碍。我们假设睡眠障碍会增强儿童期虐待受害或神经质对成年抑郁症状的影响，以及神经质在儿童期虐待受害和成年抑郁症状之间的调解影响。
方法：从2017年4月4日至2018年4月4日通过便利抽样招募的584名日本成年志愿者进行了人口统计学特征评估，童年虐待史,睡眠障碍,神经质,和抑郁症状问卷自我管理。使用简单的调节模型和调节中介模型对调查数据进行了分析。
结果：睡眠障碍与儿童期虐待或神经质对抑郁症状的交互作用呈显著正相关。此外，睡眠障碍对儿童期虐待通过神经质对抑郁症状的间接影响有显著的调节作用。
结论：因为这是一项横断面研究，因果关系无法确认。
结论：我们的研究结果表明，睡眠障碍较轻的个体由于神经质和儿童虐待而出现较少抑郁症状。此外,睡眠障碍较少的人由于童年虐待而产生的神经质抑郁症状较少。因此,睡眠障碍的改善会缓冲儿童虐待的加重效果，由各种因素引起的神经质，和儿童期虐待抑郁症状导致的神经质。
