ABSTRACT Several studies found associations between poor sleep quality and aggression in general and (forensic) psychiatric populations. Both poor sleep and aggression have been related previously to general psychopathology, but studies rarely have addressed this possible confounding factor appropriately. The current study aimed to replicate the association between sleep quality and aggression in a forensic psychiatric sample, including adjustment for psychopathology. We used cross-sectional data from an observational study in forensic psychiatric inpatients (n = 166). Poor sleep quality was significantly associated with higher self-reported aggression, independent of general psychopathology. Poor sleep quality accounted for a substantial part of the variance in aggression. This was observed for self-reported physical aggression, verbal aggression, anger, and hostility, all showing relations with poor sleep quality that were not better accounted for by general psychopathology. Poor sleep quality was related to higher clinician-rated hostility as well, however, this association was weak and the explained variance low. These results confirm and substantiate previously found associations between sleep quality and aggression in forensic psychiatric patients. They highlight the importance of targeting sleep problems as part of the treatment of psychiatric patients with disruptive behavior and encourage further research aimed at unraveling the relation between sleep and aggression.

睡眠质量与法医精神病患者的攻击性有关，独立于一般精神病理学

摘要 几项研究发现睡眠质量差与一般和（法医）精神病人群的攻击性之间存在关联。睡眠不足和攻击性以前都与一般的精神病理学有关，但研究很少适当地解决这种可能的混杂因素。目前的研究旨在在法医精神病学样本中复制睡眠质量与攻击性之间的关联，包括对精神病理学的调整。我们使用了来自法医精神病住院患者（n = 166）的观察性研究的横断面数据。睡眠质量差与更高的自我报告的攻击性显着相关，独立于一般的精神病理学。睡眠质量差是攻击性差异的很大一部分。这是观察到自我报告的身体攻击、言语攻击、愤怒和敌意，都显示出与睡眠质量差的关系，一般精神病理学无法更好地解释这些关系。睡眠质量差也与较高的临床医生评价的敌意有关，然而，这种关联很弱，解释的方差很低。这些结果证实并证实了先前发现的法医精神病患者的睡眠质量与攻击性之间的关联。他们强调了针对睡眠问题作为治疗具有破坏性行为的精神病患者的一部分的重要性，并鼓励旨在阐明睡眠与攻击性之间关系的进一步研究。这种关联很弱，解释的方差很低。这些结果证实并证实了先前发现的法医精神病患者的睡眠质量与攻击性之间的关联。他们强调了针对睡眠问题作为治疗具有破坏性行为的精神病患者的一部分的重要性，并鼓励旨在阐明睡眠与攻击性之间关系的进一步研究。这种关联很弱，解释的方差很低。这些结果证实并证实了先前发现的法医精神病患者的睡眠质量与攻击性之间的关联。他们强调了针对睡眠问题作为治疗具有破坏性行为的精神病患者的一部分的重要性，并鼓励旨在阐明睡眠与攻击性之间关系的进一步研究。
