Nightmares may be significant indicator of suicide risk

Suicide interventions targeting nightmares may be beneficial, as recent findings suggest that nightmares may be a significant marker of suicide risk.

To explore the association between nightmares and suicidal behavior, researchers evaluated 91 individuals who experienced trauma and symptoms of PTSD. Nightmares were determined by summing the frequency and intensity ratings on the Clinician-Administered PTSD scale. Study participants completed questionnaires regarding suicidal behavior, hopelessness, defeat and entrapment.

Suicidal behaviors occurred more commonly in participants who experienced nightmares (62%), compared with those who did not (20%).

Nightmares were directly and indirectly associated with suicidal behaviors through perceptions of defeat, entrapment and hopelessness, independent of comorbid insomnia and depression.

“PTSD increases the risk of suicidal thoughts and behavior, and our study shows that nightmares, a hallmark symptom of PTSD, may be an important treatment target to reduce suicide risk,” study researcher Donna L. Littlewood, PhD, of the University of Manchester, England, said in a press release. “This study emphasizes the importance of specifically assessing and targeting nightmares within those individuals experiencing PTSD.” – by Amanda Oldt
