Sleep influences daily suicidal ideation through affective reactivity to interpersonal events among high-risk adolescents and young adults

Background: Identifying proximal risk factors for suicidal ideation that are modifiable and relevant for adolescents and young adults is critical for suicide prevention. This study used an intensive monitoring approach to examine whether objectively- and subjectively- measured sleep characteristics predict next-day suicidal ideation occurrence and intensity through affective reactivity to interpersonal events in young people at […]

Defeat and entrapment mediate the relationship between insomnia symptoms and suicidal ideation in young adults

Aim In recent years, there has been a growing interest in understanding the relationship between sleep disturbance and suicide. The current study aimed to advance understanding of the psychological processes driving these relationships by examining whether insomnia symptoms are related to suicidal ideation via perceptions of defeat and entrapment. Methods Young adults (n = 259; 202 students […]

The impact of homeostatic and circadian sleep processes on non-suicidal self-injury and suicide urges in borderline personality disorder

Objective Borderline personality disorder (BPD) involves high rates of non-suicidal self-injury (NSSI) and suicidal behaviors, which are often preceded by urges. Disrupted sleep processes have been linked to NSSI and suicidal behaviors. However, it is unclear which specific sleep processes influence NSSI and suicide urges at rest (i.e., baseline) or in response to distress (i.e., […]

The moderating role of stress response on the relationship between subjective sleep quality and suicide ideation in adolescence

Objective Problems sleeping and stress are known to contribute to the development of suicide ideation. However, it is unclear how these risk factors interact longitudinally. The purpose of this study was to determine the impact of problems sleeping on the development of suicide ideation in adolescence one year later and how the relationship changes with […]

Persistent suicidal ideation in a large intensive outpatient adolescent population sample: A preliminary report on the role of sleep disturbance

Sleep disturbance is a unique, yet understudied, risk factor for suicidal thoughts and behaviors (STBs). The present study sought to explore the relationship between suicidal ideation (SI) and self-reported sleep disturbance in a sample of adolescents in an intensive outpatient program targeting suicidality (N = 691). Analyses conducted include paired samples t tests, multiple linear […]

Fear of sleep and sleep quality mediate the relationship between trauma exposure and suicide attempt in adolescents

Prior work has established bivariate associations between suicidal thoughts and behaviors, trauma exposure and sleep disturbance broadly. Specifically, this study tested whether fear of sleep and sleep quality mediated the association between trauma exposure and suicide attempt. Participants (N = 100) were adolescents admitted to an inpatient psychiatric program for suicidality. Trauma exposure history was retrieved from admission […]

Sleep disturbances predict active suicidal ideation the next day: An ecological momentary assessment study

Background Sleep disturbances are an underestimated risk factor for suicidal ideation and behavior. Previous research provided preliminary support of a temporal relationship between sleep disturbances and suicidal ideation. The present study therefore sought to investigate the prospective association between sleep disturbances, passive and active suicidal ideation, and further psychological risk factors, such as state impulsivity […]

The dynamic relationship between alpha and beta power and next-day suicidal Ideation in Individuals with treatment-resistant depression

Background Nocturnal wakefulness has emerged as a potential predictor of short-term suicide risk. This analysis used dynamic temporal patterns in alpha and beta power and global sleep metrics to explore the possible link between next-day suicidal ideation (NDSI) and wakefulness measures in unmedicated participants with treatment-resistant depression. Methods Thirty-three medication-free participants with treatment-resistant depression completed overnight polysomnography. Alpha […]

Association between hospital-diagnosed sleep disorders and suicide: A nationwide cohort study

Study Objectives: Sleep disorders are related to mental disorders. Yet few studies have examined their association with suicide. We examined whether males and females diagnosed with sleep disorders had higher rates of suicide than individuals not diagnosed with sleep disorders. Methods: In a cohort study, nationwide data on all males and females aged over 15 […]

Sleep health disparities: A promising target for preventing suicide in black youth?

Youth suicide is an urgent public health concern, particularly for Black youth, among whom suicide attempts and death have increased faster than any other racial or ethnic group. Ideal foci for suicide prevention interventions are risk factors that are malleable, dynamic, and proximal. Studies consistently identify poor sleep health as a risk factor for suicidal […]

The mediating roles of psychological pain and dream anxiety in the relationship between sleep disturbance and suicide

Suicide is a significant public health problem worldwide, and sleep disturbances have negative effects on mental health and suicidality. Several psychological concepts may mediate the relationship between sleep disturbances and suicide. We aimed to investigate the mediating roles of psychological pain and dream anxiety in this relationship. This cross-sectional study included 150 depressive patients with […]

Multicenter survey of symptoms, work life, economic status, and quality of life of complex regional pain syndrome patients

Background: Complex regional pain syndrome (CRPS) is an intractable pain disease with various symptoms. Here, we investigated the disease status, work life, sleep problems, medical insurance, economic status, psychological problems, and quality of life (QOL) of CRPS patients. Methods: CRPS patients from 37 university hospitals in South Korea were surveyed. The survey questionnaire consisted of […]

Suicidal ideation is associated with nighttime wakefulness in a community sample

Study Objectives Nocturnal wakefulness is a risk factor for suicide and suicidal ideation in clinical populations. However, these results have not been demonstrated in general community samples or compared to sleep duration or sleep quality. The present study explored how the timing of wakefulness was associated with suicidal ideation for weekdays and weekends. Methods Data […]

Insomnia symptom severity is associated with increased suicidality and death by suicide in a sample of patients with psychiatric disorders

Study objectives: Insomnia is a risk factor for suicidal behavior including attempts and death by suicide. We investigated whether insomnia symptom severity was associated with suicidality and death by suicide in patients with psychiatric disorders. Methods: The sample included 180 deceased patients with psychiatric disorders seen at Weber Human Services between 2008 and 2018 who completed the […]

The association of childhood trauma with sleep disturbances and risk of suicide in US Veterans

Background Sleep dysregulation is prevalent among veterans and is associated with increased risk of suicidal ideation and behaviors. A confluence of risk factors have been identified to date that contribute to increase risk for suicidal behavior. How these risk factors including childhood trauma, comorbid psychopathology, impulsivity, and hostility together with sleep disturbance contribute to suicide […]

The association between nocturnal panic attacks and suicidal ideation, plans, and attempts

Panic and sleep disturbances are established risk factors for suicide. Nocturnal panic attacks, which occur out of sleep, represent an intersection of these risk factors. Only one study to date has examined this relationship, but measured suicidality as a unitary construct. This represents a significant gap in the literature, considering most individuals who think about […]

Investigating the psychological mechanisms underlying the relationship between nightmares, suicide and self-harm

Evidence suggests that nightmares increase the risk of suicide and self-harm, independently of insomnia, PTSD, anxiety and depression. A better understanding of this relationship is vital for the development of effective suicide and self-harm interventions. A systematic review of the research investigating the mechanisms underlying the nightmare and suicide/self-harm relationship was therefore conducted. Findings from […]

Sleep complaints are associated with increased suicide risk independently of psychiatric disorders: Results from a national 3-year prospective study

Prior research suggests that sleep disturbances are associated with increased risk of suicide. However, sleep disturbances are associated with a wide range of psychiatric disorders, and it is unknown whether this association is independent of psychopathology. In a large nationally representative prospective survey, the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), we used […]

Sleep and suicide: A systematic review and meta-analysis of longitudinal studies

The current review provides a quantitative synthesis of the empirical literature on sleep disturbance as a risk factor for suicidal thoughts and behaviors (STBs). A systematic search of PsycINFO, MEDLINE, and the references of prior reviews resulted in 41 eligible studies included in this meta-analysis. Sleep disturbance, including insomnia, prospectively predicted STBs, yielding small-to-medium to […]

Sleep disturbances as risk factors for suicidal thoughts and behaviours: A meta-analysis of longitudinal studies

In recent years, there has been a growing interest in understanding the relationship between sleep and suicide. Although sleep disturbances are commonly cited as critical risk factors for suicidal thoughts and behaviours, it is unclear to what degree sleep disturbances confer risk for suicide. The aim of this meta-analysis was to clarify the extent to […]
