“…This discrepancy may be explained by the increased specificity of our study which accounted not only for MDD symptoms, but also for sleep disturbance and ployvictimization. The inclusion of sleep disturbances in particular may explain the lack of a direct PTSD effect on SI, as prior research in a military population found sleep disturbances were strongly related to suicidal ideation, even more so than depression and hopelessness (Ribeiro et al, 2012). As such, our study is the first to suggest that sleep disturbances may be an important comorbid determinant of the risk of suicidal ideation in PTSD sufferers, and thus should be targeted in interventions of PTSD patients in an effort to reduce suicidal behaviors.…”

“…In addition to being associated with an increased risk of suicide and suicidal behaviors (Goldstein, Bridge, & Brent, 2008;Ribeiro et al, 2012;Wong, Brower, & Zucker, 2011), evidence shows that sleep disturbances are highly prevalent in those with PTSD, found to increase in severity along with PTSD symptom severity and to hinder PTSD remission (Brown et al, 2011;Germain, Buysse, Shear, Fayyad, & Austin, 2004). Some suggest that sleep disturbance may even constitute an under-acknowledged set of 'night time PTSD symptoms' developing alongside PTSD symptoms as a consequence of trauma exposure (Spoormaker & Montgomery, 2008).…”

“…6,7 A number of studies have demonstrated that insomnia is strongly associated with suicidal ideation cross-sectionally 8,9,10 and longitudinally, 11,12 even when controlling for hopelessness and depression. 13 Furthermore, several studies have established a link between insomnia and death by suicide among adolescents, 14 adults, 15 and older adults, 16 underscoring insomnia as a critical risk factor for suicide. In a population-based longitudinal study of non-depressed individuals in South Korea, those with persistent insomnia were nearly two times more likely to Despite strong evidence of the association between insomnia and suicide, little is known about the underlying mechanisms by which insomnia may be linked to increased suicide risk.…”

“…In a population-based longitudinal study of non-depressed individuals in South Korea, those with persistent insomnia were nearly two times more likely to Despite strong evidence of the association between insomnia and suicide, little is known about the underlying mechanisms by which insomnia may be linked to increased suicide risk. Although several hypotheses have been proffered (e.g., emotion dysregulation as an explanatory link 16,18 ; insomnia as a component of overarousal, which is also a risk factor for suicide 13 ), these conjectures have largely been untested. To further delineate the connection between insomnia and suicide, it thus may be useful to turn to theoretical models of suicide-in particular, the interpersonal theory of suicide.…”

Study Objectives: Suicide is a serious public health problem, and suicide rates are particularly high in South Korea. Insomnia has been identified as a risk factor for suicidal ideation; however, little is known about the mechanisms accounting for this relationship in this population. Based on the premise that insomnia can be lonely (e.g., being awake when everyone else is asleep), the purpose of this study was to examine whether greater insomnia severity would be associated with higher levels of thwarted belongingness and suicidal ideation, and whether thwarted belongingness would mediate the relationship between insomnia and suicidal ideation. Methods: Predictions were tested in a sample of 552 South Korean young adults who completed self-report measures of insomnia severity, suicidal ideation, and thwarted belongingness. Results: Greater insomnia symptom severity was significantly and positively associated with thwarted belongingness and suicidal ideation. Mediation analyses revealed that thwarted belongingness significantly accounted for the relationship between insomnia severity and suicidal ideation. Conclusions: These findings highlight the potential importance of monitoring and therapeutically impacting insomnia and thwarted belongingness to help reduce suicide risk.

“…19 Additionally, a recent study among older adults found that poor sleep quality predicted future death by suicide after controlling for baseline depressive symptoms. 15 However, other studies have found that the association between insomnia and suicide risk is mediated by other psychopathology.…”

BRIEF SUMMARYCurrent Knowledge/Study Rationale: Research has shown relations between duration of insomnia symptoms/duration of nightmares and suicide risk in younger adults. However, this relation has not been examined in older adults. Study Impact: The present study found that, in older adults, nightmare duration was related to suicide risk independent of current nightmares, current symptoms of and duration of insomnia, and symptoms of anhedonia and PTSD. Nightmare duration was also related to suicide risk independent of the IPTS. Thus, nightmare duration is an important factor to be assessed when evaluating the level of suicide risk with patients.Objective: Duration of insomnia symptoms and nightmares are related to suicidal risk in young adults independent of current symptoms of insomnia, nightmares, anxiety, depression, and PTSD. However, this relation has yet to be examined among older adults, despite older adults being at higher risk of suicidal behavior. Further, the current study aims to replicate previous research among younger adults showing that insomnia symptoms and nightmares are associated with suicide risk independent of the interpersonal psychological theory of suicide (IPTS). Methods: The present study utilized 167 participants age 55 and older obtained by combining two independent mTurk data collections of adults in the United States. Results: In the current sample, duration of nightmares was associated with suicide risk in older adults independent of symptoms of current insomnia and nightmares, duration of insomnia, and symptoms of PTSD, anhedonia, and the IPTS. Conclusions: Our fi ndings suggest that the duration of nightmares (i.e., how long someone has been experiencing nightmares) predict substantial variance in suicide risk among older adults in addition to the risk factors typically examined. S uicide is a leading cause of death, yet it remains a challenge to predict and prevent. In 2012, suicide was the tenth leading cause of death in the United States, accounting for 40,600 deaths.1 Further, 2012 marks the fi rst time in history that U.S. deaths by suicide have exceeded 40,000 in a year.2 Suicide is a particularly large problem for older adults: although older adults only made up about 13.7% of the population in 2012, older adults represented 16.4% of suicides.1 Suicidal intent, which refers to the degree to which one desires to end his/her life by suicidal behavior, 3 is more common in older adults than in the rest of the population, and attempts made by older adults are more likely to be fatal. 4 To illustrate this, there are 100-200 attempts for every one youth suicide and 4 attempts for every one older adult suicide.5 Thus, older adult suicide attempts are much more likely to be fatal than younger adult suicide attempts. Research has identifi ed many risk factors for older adult suicide including the loss of independence, social isolation, mental illness, and decline in physical health. 4,[6][7][8] However, despite having identifi ed these risk factors, clinicians are still very po...
