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 […]

The experience of pain is strongly associated with poor sleep quality and increased risk for suicide

Objective Effective suicide prevention is hindered by a limited understanding of the neurobiology leading to suicide. We aimed to examine the association between changes in the experience of pain and disturbances in sleep quantity and quality in patients with elevated risk for suicide. Methods Three groups of adult depressed individuals, including patients following a recent […]

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., […]

24-hour movement guidelines and suicidality among adolescents

Background: The 24-hour movement guidelines for children and youth recommend ≥60 min/day of moderate-to-vigorous physical activity, ≤2 h/day of screen time, 9-11 h/night of sleep for 11-13 years and 8-10 h/night for 14-17 years. The objectives of this study were to examine the associations between meeting combinations of the recommendations contained within the 24-hour movement guidelines […]

Overarousal interacts with a sense of fearlessness about death to predict suicide risk in a sample of clinical outpatients

Converging evidence suggests that acute states of overarousal are common prior to suicidal behavior. Yet, there has been very little theory-driven research of these phenomena. We consider two competing theoretical perspectives. The first is consistent with the interpersonal theory of suicide, which suggests that the prospect of engaging in lethal suicidal behavior should elicit some degree […]

Isolating the association of sleep, depressive state, and other independent indicators for suicide ideation in United States teenagers

According to the Centers for Disease Control and Prevention, suicide is the second leading cause of death in American teenagers, and is a growing public health concern. This study uses multivariable logistic regression to investigate the independent relationship between suicide ideation and sleep duration in teenagers using the 2015 Youth Behavior Risk Surveillance Study, controlling […]

Rumination in relation to suicide risk, ideation, and attempts: Exacerbation by poor sleep quality?

BACKGROUND: Rumination, particularly brooding rumination, is associated with suicide risk, ideation and attempts; however, findings are inconsistent with respect to reflective rumination. Recent research suggests reflective rumination might be associated with increased suicide risk specifically among vulnerable individuals. Poor sleep quality is related to both suicide risk and rumination, yet no research has examined whether […]

Neurocognitive game between risk factors, sleep and suicidal behaviour.

Introduction Sleep and lifestyles interact to allow the appropriate development of cerebral structures, and prevention of mood disorders. But just a hand of articles identified a precise relationship between these two above, and the probability to develop a suicidal behaviour. Objective The aim of this study is to explore how the suicidal behaviour is associated […]

Insomnia and hypnotic medications are associated with suicidal ideation in a community population.

Suicidal ideation (SI), a significant predictor of suicide, is associated with sleep disturbance, which is seldom assessed using stringent diagnostic criteria and validated sleep instruments in community samples. Cross-sectional data, including sleep diaries and validated instruments, from 767 community adults were used to identify variables associated with SI and subsequently entered into a regression model […]

Sleepless in Fairfax: The difference one more hour of sleep can make for teen hopelessness, suicidal ideation, and substance use.


Prevalence and correlates of sleep disturbance and depressive symptoms among Chinese adolescents: A cross-sectional survey study.

Sleep disturbance was determined to be more prevalent among Chinese adolescents with depressive symptoms. Sleep disturbance and depressive symptoms were associated with each other, while school factors, family factors and psychosocial adjustment were comprehensively correlated with both.

Sleep disturbance preceding suicide among veterans.

Objectives. We examined the role of sleep disturbance in time to suicide since the last treatment visit among veterans receiving Veterans Health Administration (VHA) services. Methods. Among 423 veteran suicide decedents from 2 geographic areas, systematic chart reviews were conducted on the 381 (90.1%) who had a VHA visit in the last year of life. […]

Associations between non-restorative sleep, short sleep duration and suicidality: findings from a representative sample of Korean adolescents.

Aims This study clarifies the associations among sleep duration, non-restorative sleep, suicidal ideation and suicide attempts in a representative sample of Korean adolescents. Methods Analyses are based on data from the 2007 Korean Youth Risk Behavior Web-based Survey. The survey used a cross-sectional, national and representative sample consisting of 78 843 students (grades 7Ð12) who were […]

Early onset of action and sleep-improving effect are crucial in decreasing suicide risk: the role of quetiapine XR in the treatment of unipolar and bipolar depression.

Although the possibilities of antidepressive pharmacotherapy are continuously improving, the rate of nonresponders or partial responders is still relatively high. Suicidal behavior, the most tragic consequence of untreated or unsuccessfully treated depression, commonly observed in the first few weeks of antidepressive treatment before the onset of therapeutic action, is strongly related to certain symptoms of […]

Insomnia symptoms, nightmares, and suicidal ideation in older adults.

Sleep, Serotonin, and Suicide in Japan

This article reviews evidence supporting the hypothesis that suicide rates in Japan could be reduced by elevating serotonin levels via increasing the average duration of sleep. From the research reviewed, 2 major problematic issues were apparent: most people in Japan receive inadequate sleep & individuals whose sleep is inadequate are unlikely to be sufficiently physically […]

Is Disturbed Sleep a Clinically Useful Marker to Determine the Suicide Risk in Patients With Post-Traumatic Stress Disorder?

In this letter to the editor, the authors draw particular attention to the association of suicidality with disturbed sleep among patients with posttraumatic stress disorder. Some of the links that may exist between posttraumatic stress disorder, sleep abnormalities, & suicidal behaviour are briefly outlined. It is concluded that it is reasonable to suggest that disturbed […]

Associations Between Lifestyle Factors, Working Environment, Depressive Symptoms and Suicidal Ideation: a Large-Scale Study in Japan

Associations between lifestyle, working environment, depressive symptoms, & suicide ideation were investigated. Variables measured included job stressors, working hours, overtime work, smoking status, alcohol consumption, sleep, exercise, meals, & family factors.

Sleep Disturbances and Suicide Risk: a Review of the Literature

This article provides a critical review of the extant literature on sleep & suicidality, & addresses shared underlying neurobiological factors, biological & social “zeitgebers”, treatment implications, & future directions for research. Findings indicate suicide ideation & behaviours are closely associated with sleep complaints, & in some cases, this association exists above & beyond depression. Several […]

Sleep and Suicidality: do Sleep Disturbances Predict Suicide Risk?

In this editorial, the authors review some of the research that has examined whether or not sleep disturbances have significance in predicting suicide among patients with mood disorders. They also discuss an article by Bernert & colleagues in this journal issue on suicidality & sleep disturbances. (14 refs.)
