Key result
Insomnia links to current suicidal ideation in military personnel only at high levels of agitation.
Why the study?
The moderating role of agitation in the relationship between insomnia and current suicidal ideation in military personnel was unclear.
Observational
Agitation moderates the relationship between insomnia and suicidal ideation in military personnel, suggesting both are important targets for suicide risk detection.
Agitation may moderate insomnia-suicidal ideation links in military personnel; hypothesis-generating and should not yet change practice.
Research has established a link between agitation and insomnia, both of which are considered to be risk factors for suicide. The present study aimed to investigate the moderating role of agitation within the relationship between insomnia and current suicidal ideation in a sample of U.S. military personnel. Consistent with hypotheses, the relationship between insomnia and current suicidal ideation was significant only at high levels of agitation. Results support previous findings indicating that both insomnia and agitation are suicide risk factors. These findings clarify the role of known risk factors in the pathway to suicide and may contribute to the advancement of suicide detection and prevention, as these factors may be more easily identified in individuals unwilling to admit thoughts of death and suicide, such as many military personnel.

Fisher et al. (2016) conducted an observational in Suicidal ideation. Insomnia and agitation was evaluated on Current suicidal ideation. Insomnia was significantly associated with current suicidal ideation only at high levels of agitation in U.S. military personnel.
