“…However, across numerous studies, associations between insomnia symptoms and suicide-related variables have been independent of depressive symptoms and/or other potential confounders (ie, age, sex, fatigue, chronic health problems, anhedonia, hopelessness, anxiety symptoms, substance use, cognitive ability, or the presence of any psychiatric illness). 19 , 23 , 25 , 30 , 31 , 33 , 34 , 40 , 42 , 46 , 48 , 51 , 57 , 61 , 64 , 66 , 68 , 69 , 72 – 74 …”

“…Additional inconsistencies include the risk conferred by specific insomnia symptoms (see Table 2 ). Research does not show a clear pattern regarding whether onset, maintenance, or terminal insomnia independently heighten suicide risk, with several studies showing that concurrently reporting two of these three insomnia symptoms may confer greater risk for suicide ideation 40 , 42 , 46 , 57 and attempts, 30 , 31 , 75 , 76 intent to attempt suicide, 72 and death by suicide. 66 This suggests that greater risk may result from the presence of multiple sleep disturbances.…”

Suicidality in sleep disorders: prevalence, impact, and management strategies

Sleep disturbances are associated with suicide-related thoughts and behaviors, and the incidence of sleep concerns and suicide has increased recently in the US. Most published research exploring the sleep–suicidality relation is focused on select sleep disorders, with few reviews offering a comprehensive overview of the sleep–suicidality literature. This narrative review broadly investigates the growing research literature on sleep disorders and suicidality, noting the prevalence of suicide ideation and nonfatal and fatal suicide attempts, the impact of several sleep disorders on suicide risk, and potential sleep-disorder management strategies for mitigating suicide risk. Aside from insomnia symptoms and nightmares, there exist opportunities to learn more about suicide risk across many sleep conditions, including whether sleep disorders are associated with suicide risk independently of other psychiatric conditions or symptoms. Generally, there is a lack of randomized controlled trials examining the modification of suicide risk via evidence-based sleep interventions for individuals with sleep disorders.

“…Findings are mixed, though, on whether depression affects this association. At least one study found that short sleep duration was associated with suicidal ideation independent of depression in adults (21), whereas other studies found that depression better explains the association between sleep duration and suicidality (22,23). Among individuals who have suicidal ideation, shorter sleep duration, and poorer sleep quality predicted next day increases in suicidal ideation even when adjusting for depression severity.…”

“…Among individuals who have suicidal ideation, shorter sleep duration, and poorer sleep quality predicted next day increases in suicidal ideation even when adjusting for depression severity. Some researchers have proposed that short or long sleep duration may interact with insomnia, such that the two combined result in greater suicidality (22,24).…”

Insomnia Is Associated With Frequency of Suicidal Ideation Independent of Depression: A Replication and Extension of Findings From the National Health and Nutrition Examination Survey

Objective: Insomnia is associated with suicidality, although the mechanisms of this association are unclear. This study sought to replicate previous findings showing that insomnia symptoms but not sleep duration are associated with frequency of suicidal ideation in adults. We further investigated whether depression or sleep duration moderates the association between insomnia symptoms and frequency of suicidal ideation. Materials and Methods: We used the 2005-2006 cycle of the National Health and Nutrition Examination Survey to replicate previously reported findings from the 2007-2008 cycle. We used ordered logistic regression to determine whether insomnia symptoms were associated with frequency of suicidal ideation independently of depression and other potential confounds. To extend these findings, we tested whether depression or sleep duration moderated the association between insomnia symptoms and frequency of suicidal ideation. We further replicated these findings in parallel analyses using the combined data from the 2005-2006 and 2007-2008 cycles. Results: This study replicated previous results showing that insomnia symptoms are associated with frequency of suicidal ideation in the NHANES 2005-2006 cycle (OR = 1.09, p < 0.05), even after adjusting for potentially confounding variables, including depression. Neither depression nor sleep duration moderated this association. Difficulty with sleep maintenance insomnia symptoms were most robustly associated with frequency of suicidal ideation (OR ≥ 1.97, p < 0.05). Sleep duration was not robustly associated with suicidal ideation. Conclusions: In this study, we found that insomnia symptoms were uniquely associated with frequency of suicidal ideation. This association cannot be explained by the shared association with depression or sleep duration.
