We conducted a longitudinal study to investigate the relation between sleep experiences and dissociative symptoms in a mixed inpatient sample at a private clinic evaluated on arrival and at discharge 6 to 8 weeks later. Using hierarchical regression analyses and structural equation modeling, we found a link between sleep experiences and dissociative symptoms and determined that specifically decreases in narcoleptic experiences rather than insomnia accompany a reduction in dissociative symptoms. Although sleep improvements were associated with a general reduction in psychopathology, this reduction could not fully account for the substantial and specific effect that we found for dissociation. Our findings are consistent with Watson's (2001) hypothesis that disruptions in the sleep-wake cycle lead to intrusions of sleep phenomena into waking consciousness, resulting in dissociative experiences. Accordingly, sleep hygiene may contribute to the treatment or prevention of dissociative symptoms.
我们进行了一项纵向研究，以调查在私人诊所入院时和 6 至 8 周后出院时的混合住院样本中睡眠体验与分离症状之间的关系。使用分层回归分析和结构方程模型，我们发现睡眠体验与分离症状之间存在联系，并确定嗜睡体验的减少而不是失眠与分离症状的减少有关。尽管睡眠改善与精神病理学的一般减少有关，但这种减少并不能完全解释我们发现的对分离的实质性和特异性影响。我们的研究结果与 Watson 的假设一致，即睡眠-觉醒周期的中断导致睡眠现象侵入清醒意识，导致分离体验。因此，睡眠卫生可能有助于分离症状的治疗或预防。
