title: Insomnia symptoms, nightmares, and suicidal ideation in a college student sample.
abstract: OBJECTIVE
  The purpose of this study was to investigate whether insomnia symptoms and nightmares are related to suicidal ideation independent of one another and independent of the symptoms of anxiety, depression, and posttraumatic stress disorder (PTSD).
  
  
  METHODS
  The study consisted of questionnaires examining insomnia symptoms and nightmares, and symptoms of depression, anxiety, and PTSD. The questionnaires were administered online.
  
  
  METHODS
  University.
  
  
  METHODS
  583 undergraduate students at a large, public university in southeastern United States.
  
  
  METHODS
  N/A.
  
  
  RESULTS
  Results indicated that both nightmares and insomnia symptoms were related to suicidal ideation, independent of one another. Nightmares, but not insomnia symptoms, were related to suicidal ideation after controlling for the symptoms of anxiety, depression, and PTSD.
  
  
  CONCLUSIONS
  Nightmares may be more than a marker of PTSD and hence may be important in the identification of suicidal ideation.
