Insomnia symptoms may be an important predictor of suicidal ideation in military troops, an MSRC-Funded study has found.

For the study, researchers evaluated 311 soldiers (255 men and 56 women) who were recruited as part of a treatment study for severe suicidality from two outpatient clinics, an inpatient facility and an emergency department.

Researchers then examined the cross-sectional and longitudinal relationships between insomnia symptoms and suicidal ideation and behavior. They controlled for depressive symptom severity, hopelessness, PTSD diagnosis, anxiety symptoms and drug and alcohol abuse symptoms in the study sample.
