The relationship between suicidal responses and traumatic brain injury and severe insomnia in active duty, veteran, and civilian populations

This study examined how a positive traumatic brain injury (TBI) screening and insomnia severity relate to suicidal outcomes across active duty, veteran, and civilian samples. Data were used from 3,993 participants from 19 studies. We conducted a series of analyses by group to identify which significantly differed on the variables of interest. TBI and insomnia […]

Insomnia symptoms predict emotional dysregulation, impulsivity and suicidality in depressive bipolar II patients with mixed features

Adolescent insomnia, suicide risk, and the interpersonal theory of suicide

Although insomnia has been repeatedly linked with suicide ideation, the reason for the linkage is not clear. The Interpersonal Psychological Theory of Suicide (IPTS) proposes that three core variables (thwarted belongingness, perceived burdensomeness, and acquired capability) are the final common pathway for all risk factors for suicide ideation and behavior. Recent research has suggested that insomnia may be associated with […]
