Insomnia Symptoms,Nightmares, and Suicide Risk: Duration of Sleep Disturbance Matters

Duration of insomnia symptoms or nightmares was investigated to see if it was related to suicide risk independent of current insomnia symptoms, nightmares, anxiety symptoms, depressive symptoms, and posttraumatic symptoms. The cross‐sectional study involved analyses of survey responses from undergraduate students who endorsed either insomnia symptoms (n = 660) or nightmares (n = 312). Both insomnia symptom and nightmare duration were significantly associated with suicide risk independent of current insomnia symptoms or nightmares, respectively. Relations were also significant after controlling for anxiety symptoms, depressive symptoms, and posttraumatic symptoms. Results suggest that duration of sleep disturbance is relevant when assessing suicide risk.     

Capable of Suicide: A Functional Model of the Acquired Capability Component of the Interpersonal‐Psychological Theory of Suicide

A functional model of the acquired capability for suicide, a component of Joiner's (2005 ) Interpersonal‐Psychological Theory of Suicide, is presented. A component of Joiner's (2005 ) Interpersonal‐Psychological Theory of Suicide a functional model of the acquired capability for suicide is presented. The model integrates the points discussed by Joiner into a unified and specific conceptualization of acquired capability. Several points are elaborated on, such as the interaction between specific diatheses with life events, the role of short‐term bolstering of the capability for suicide, and how contextual factors moderate the experience of painful and provocative life events; thereby leading to fearlessness and pain insensitivity to the actions and ideas involved in suicide.     

The Effects of the Family Bereavement Program to Reduce Suicide Ideation and/or Attempts of Parentally Bereaved Children Six and Fifteen Years Later

Findings concerning the long‐term effects of the Family Bereavement Program (FBP) to reduce suicide ideation and/or attempts of parentally bereaved children and adolescents are presented. Parental death is a significant risk factor for suicide among offspring (Guldin et al., 2015). This study is a long‐term follow‐up of 244 children and adolescents who had participated in a randomized trial of the FBP, examining the intervention effects on suicide ideation and/or attempts as assessed through multiple sources. Results indicate a significant effect of the FBP to reduce suicide ideation and/or attempts at the 6‐ and 15‐year follow‐up evaluation. The findings support the potential benefits of further research on “upstream” suicide prevention.     

Risk Factors of a Suicide Reattempt by Seasonality and the Method of a Previous Suicide Attempt: A Cohort Study in a Japanese Primary Care Hospital

Suicide has a great impact on the individual whose life is lost and the bereaved family members. The risk of a suicide reattempt is particularly high during the first 12 months after a suicide attempt. In this cohort study, risk factors for a suicide reattempt were explored among 291 patients at suicide risk. Clinical and demographic data were collected from a Japanese primary care hospital. Past psychiatric history and multiple diagnoses were associated with suicide reattempts in both genders. Drug overdose, past psychiatric history, and the summer season were linked to suicide reattempts among males. Past psychiatric history and multiple diagnoses were linked to suicide reattempts among females. Appropriate assessment of past psychiatric history, season and method of suicide attempt, gender, and diagnosis may play a role in preventing suicide.     

Is Cumulative Exposure to Suicide Attempts and Deaths a Risk Factor for Suicidal Behavior Among Firefighters? A Preliminary Study

The association between cumulative exposure to suicide attempts and deaths and suicidal behavior was examined in a sample of 61 professional firefighters. On average, firefighters reported 13.1 (SD = 16.6) exposures over the course of their lifetime. Cumulative exposure to suicide attempts and deaths was positively correlated with suicidal behavior (r = .38, p = .004). Moreover, firefighters with 12+ exposures were more likely to screen positive for risk of suicidal behavior (OR = 7.885, p = .02). Additional research on the potential impact of cumulative exposure to suicide attempts and deaths on firefighters' health and safety is needed.     

Physical Activity,Suicide Risk Factors,and Suicidal Ideation in a Veteran Sample

The association between current level of suicidal ideation and physical activity was tested in a broad sample of veterans seeking care from the Veterans Health Administration. It was hypothesized that the two variables would be significantly inversely related. It was further hypothesized that the relationship would be mediated by depressive symptoms, disturbed sleep, and a measure of heart rate variability based on existing research regarding physical activity and sleep. Due to the first hypothesis not being supported, the second could not be tested. Post hoc correlation analyses did find associations between physical activity and depressive symptoms, in expected directions, and are discussed. Possible explanations for the negative findings along with recommendations for future research to continue exploring links between suicide risk and physical activity are presented. We conclude by suggesting that physical activity may have promise as a risk reduction intervention and that prospective data are more likely to yield significant results than the cross‐sectional methodology employed in the current study.     

Psychiatric and Self‐Injury Profiles of Adolescent Suicide Attempters versus Adolescents Engaged in Nonsuicidal Self‐Injury

To better delineate the unique correlates of self‐injurious behaviors (SIB), psychiatric profiles of mutually exclusive groups of adolescents who made a suicide attempt (SA) versus those engaged in nonsuicidal self‐injury (NSSI) were examined. Contrary to hypotheses, the NSSI group endorsed earlier onsets of SIB and suicidal ideation (SI), as well as higher rates of depression and anxiety compared with their SA counterparts. Future work is warranted to understand the role of SI, including duration of SI and anxiety in the development of NSSI, and to identify risk and resiliency factors useful in predicting an adolescent's SIB status.
