ABSTRACT To study the prevalence of specific sleep disturbances in suicide attempters and to examine the association between specific sleep disturbances and suicidality.
A cross-sectional study in suicide attempters during the period October 1, 2001, to June 30, 2004.
One hundred sixty-five patients aged 18 to 68 years who were admitted to medical units or psychiatric wards at Sahlgrenska University Hospital after a suicide attempt.
N/A.
The face-to-face interview included Structured Clinical Interview for DSM-IV-IV and the Suicide Assessment Scale. Two self-report instruments were employed, the Uppsala Sleep Inventory and Comprehensive Psychopathological Self-rating Scale for Affective Syndromes. The latter assessed symptom burden. Using multiple logistic regression analyses, we examined associations between sleep complaints and suicidality.
Eighty-nine percent of subjects reported some kind of sleep disturbance. The most common complaint was difficulties initiating sleep (73%). Other complaints included difficulties maintaining sleep (69%), nightmares (66%) and early morning awakening (58%). Nightmares were associated with a 5-fold increase in risk for high suicidality. This relationship remained after adjustment for psychiatric diagnosis and psychiatric symptom intensity.
Sleep disturbances are common among suicide attempters. Nightmares are associated with suicidality. Our findings suggest that questions concerning sleep disturbance and nightmares should be addressed in the clinical assessment of suicidal patients.

    ABSTRACT: Sleep disturbances are among the most commonly endorsed symptoms of post-traumatic stress disorder (PTSD). Treatment modalities that are effective for the waking symptoms of PTSD may have limited efficacy for post-traumatic sleep problems. The aim of this review is to summarize the evidence for empirically supported and/or utilized psychotherapeutic and pharmacological treatments for post-traumatic nightmares and insomnia. While there are few controlled studies of the applicability of general sleep-focused interventions to the management of the sleep disturbances in PTSD, evidence is growing to support several psychotherapeutic and pharmacological treatments. Future investigations should include trials that combine treatments focused on sleep with treatments effective in managing the waking symptoms of PTSD.

    ABSTRACT: Most measures of depression severity are based on the number of reported symptoms, and threshold scores are often used to classify individuals as healthy or depressed. This method – and research results based on it – are valid if depression is a single condition, and all symptoms are equally good severity indicators. Here, we review a host of studies documenting that specific depressive symptoms like sad mood, insomnia, concentration problems, and suicidal ideation are distinct phenomena that differ from each other in important dimensions such as underlying biology, impact on impairment, and risk factors. Furthermore, specific life events predict increases in particular depression symptoms, and there is evidence for direct causal links among symptoms. We suggest that the pervasive use of sum-scores to estimate depression severity has obfuscated crucial insights and contributed to the lack of progress in key research areas such as identifying biomarkers and more efficacious antidepressants. The analysis of individual symptoms and their causal associations offers a way forward. We offer specific suggestions with practical implications for future research.

    ABSTRACT: Increasing research indicates that sleep disturbances may confer increased risk for suicidal behaviors, including suicidal ideation, suicide attempts, and death by suicide. Despite increased investigation, a number of methodological problems present important limitations to the validity and generalizability of findings in this area, which warrant additional focus. To evaluate and delineate sleep disturbances as an evidence-based suicide risk factor, a systematic review of the extant literature was conducted with methodological considerations as a central focus. The following methodologic criteria were required for inclusion: the report (1) evaluated an index of sleep disturbance; (2) examined an outcome measure for suicidal behavior; (3) adjusted for presence of a depression diagnosis or depression severity, as a covariate; and (4) represented an original investigation as opposed to a chart review. Reports meeting inclusion criteria were further classified and reviewed according to: study design and timeframe; sample type and size; sleep disturbance, suicide risk, and depression covariate assessment measure(s); and presence of positive versus negative findings. Based on keyword search, the following search engines were used: PubMed and PsycINFO. Search criteria generated N = 82 articles representing original investigations focused on sleep disturbances and suicide outcomes. Of these, N = 18 met inclusion criteria for review based on systematic analysis. Of the reports identified, N = 18 evaluated insomnia or poor sleep quality symptoms, whereas N = 8 assessed nightmares in association with suicide risk. Despite considerable differences in study designs, samples, and assessment techniques, the comparison of such reports indicates preliminary, converging evidence for sleep disturbances as an empirical risk factor for suicidal behaviors, while highlighting important, future directions for increased investigation.
