New Study Reveals Sleep Treatments Significantly Reduce Suicidal Thoughts in Veterans

Reading Time: 2 minutes

In a new study conducted by a collaborative team from Stanford University and other institutions, a novel non-pharmacological treatment for insomnia has shown significant potential for reducing suicidal thoughts among military veterans. This new approach, focusing on rapid behavioural interventions, offers hope for addressing the critical public health issue of veteran suicides, which occur at alarmingly high rates.

The study employed a controlled, randomised trial format to evaluate the effectiveness of the newly developed Sleep Enhancement for Returning Veterans (SERVE) programme. This intervention contrasts sharply with traditional treatments, which have often been mismatched to the acute nature of suicidal crises. The findings were published in the journal Sleep.

Suicide rates among veterans have consistently been a cause for concern, with this demographic facing unique challenges that increase their risk. The innovative SERVE programme incorporates elements of cognitive behavioural therapy for insomnia (CBTi) and Imagery Rehearsal Treatment (IRT), condensed into a rapid four-session format. The results have been promising, indicating not only improved sleep outcomes but also significant reductions in suicidal ideation and related depressive symptoms.

During the trial, 77 veterans suffering from severe insomnia and exhibiting suicidal tendencies were enrolled and randomised into two groups: those receiving the active treatment and a control group receiving an arousal-based treatment of insomnia (ABTI). Both interventions were matched for therapist contact time and educational materials but differed in therapeutic approach.

The findings were striking. The veterans who underwent the SERVE programme demonstrated large decreases in both the intensity of their suicidal thoughts and the severity of insomnia, with improvements sustained over follow-up periods. These outcomes were significantly better than those observed in the control group, highlighting the potential of targeted sleep interventions in this high-risk population.

Researchers believe that the relationship between poor sleep and increased suicidality may involve factors like depression, emotion dysregulation, and perceived burdensomeness. By addressing insomnia, which is often more readily acknowledged and less stigmatised than other psychiatric symptoms, the SERVE programme provides an accessible and effective intervention that could be a crucial component in suicide prevention strategies for veterans.

This study not only supports the viability of brief behavioural interventions for insomnia but also emphasises the broader implications of treating sleep disorders as a way to mitigate mental health crises among vulnerable populations. With continued support and further research, programmes like SERVE could be refined and expanded, offering a lifeline to veterans and potentially other high-risk groups.

The implications of these findings extend beyond the military, suggesting that similar strategies could be adapted for civilian use, particularly among populations at high risk for suicide. The approach taken by the researchers to integrate treatment for insomnia into broader mental health interventions could revolutionise how we address the intertwined issues of sleep and mental health.
