title: Insomnia symptoms, nightmares, and suicide risk: duration of sleep disturbance matters.
abstract: Duration of insomnia symptoms or nightmares was investigated to see if it was related to suicide risk independent of current insomnia symptoms, nightmares, anxiety symptoms, depressive symptoms, and posttraumatic symptoms. The cross-sectional study involved analyses of survey responses from undergraduate students who endorsed either insomnia symptoms (n = 660) or nightmares (n = 312). Both insomnia symptom and nightmare duration were significantly associated with suicide risk independent of current insomnia symptoms or nightmares, respectively. Relations were also significant after controlling for anxiety symptoms, depressive symptoms, and posttraumatic symptoms. Results suggest that duration of sleep disturbance is relevant when assessing suicide risk.
