Insomnia is a unique and robust indicator of suicidal thoughts, regardless of the co-existence of a mood disorder, such as depression. And, the intervention that is most effective for insomnia may also reduce suicidality. Research and clinical practice have repeatedly shown that Cognitive Behavioral Therapy for insomnia (CBT-I) is the best intervention for insomnia (superior to medications). More recent studies have shown that improving sleep itself may also reduce suicidal thoughts – which tend to remit by about half after treatment for insomnia compared to control groups, even without directly attempting to reduce suicidal thoughts. In addition, a digital (electronic) option to treat insomnia and suicidal thoughts may be as effective as CBT-I, making it less costly and more accessible for more people than in-person care.
CBT-I includes behavioral components such as sleep restriction, sleep hygiene, and stimulus control, as well as cognitive components like cognitive restructuring, paradoxical intention, and psychoeducation. It also frequently includes relaxation practices such as progressive muscle relaxation, breathing, and mindfulness. All of these components are tailored over multiple sessions for each person.
Below are three studies that support CBT-I in-person treatment for reducing suicidal thoughts:
A similar trend was found with pregnant women using a digital CBT-I intervention, with suicidal thoughts going from 5.5% to 0% (Kalmbach, et al, 2020). The same researchers at the Thomas Roth Sleep Disorders and Research Center in Detroit, Michigan, used a digital intervention of CBT-I in a larger study over six treatment sessions. This intervention was an automated and interactive online program. They used an eHealth animated “virtual therapist” that was fully-automated and standardized to track participant progress and make suggestions based on the sleep data they submitted.
The results of this study showed 70% reduction in suicidal thoughts in the CBT-I condition at posttreatment. “[This] remained consistent a year later at a 72% reduction,” they report. The control condition, who had the same number of contact sessions but with educational information only, had a 45% reduction in suicidal thoughts. While the control group effects may be dismissed as placebo effect, 45% still strikes me as a powerful shift. And, I would argue it is important to realize that even without the tailored intervention, care-based attention, hope, and taking actions of self-care play a powerful role in wellness in ways we may not expect.
This study is the first study to demonstrate CBT-I efficacy for alleviating and preventing suicidal thoughts using an eHealth digital delivery format. Overall, these findings suggest that digital CBT-I can serve a role in alleviating and even preventing suicidal thoughts in insomnia patients and that insomnia remission is a critical part of mitigating suicide risk. These findings are consistent with prior studies supporting the effectiveness of CBT-I on suicidal risk. This may be especially important, as some studies have found that the night-time risk of suicide is approximately three times that of daytime risk (Tubbs, et al., 2020).
