Mood,Anxiety, and Substance‐Use Disorders and Suicide Risk in a Military Population Cohort

There are meager prospective data from nonclinical samples on the link between anxiety disorders and suicide or the extent to which the association varies over time. We examined these issues in a cohort of 309,861 U.S. Air Force service members, with 227 suicides over follow‐up. Mental disorder diagnoses including anxiety, mood, and substance‐use disorders (SUD) were based on treatment encounters. Risk for suicide associated with anxiety disorders were lower compared with mood disorders and similar to SUD. Moreover, the associations between mood and anxiety disorders with suicide were greatest within a year of treatment presentation.     

Suicide on Railroad Rights‐of‐Way: A Psychological Autopsy Study

Findings from 55 psychological autopsies of decedents who perished on U.S. railroad rights‐of‐way between October 1, 2007, and September 30, 2010 are reported. Described are distal, proximal, and contextual factors of risk; understandings of why these suicides occurred on railroad rights‐of‐way; and opportunities for prevention of similar suicides. International comparisons of suicides on railroad rights‐of‐way are made to highlight distinct findings regarding U.S. cases. Decedents studied exhibited considerable predisposing risk for suicide, with a high prevalence of severe mental disorders and substance abuse. In addition, a number of acute risk factors were commonly observed, notably suicide ideation, hopelessness, anxiety, and anger. In the context of that acute risk, associated situational variables and a relative absence of protective factors are described.     

Longitudinal Associations between Violence and Suicidality from Adolescence into Adulthood

The link between violence and suicide is well documented. Previous studies, however, largely rely on cross‐sectional designs or only consider violence as an antecedent of suicide. The purpose of the current study was to investigate the longitudinal relationship between violence and suicide from adolescence into young adulthood. Data were derived from Wave II (1995–1996), Wave III (2001–2002), and Wave IV (2007–2008) of the National Longitudinal Study of Adolescent Health (N = 8,966). We tested (2011–2013) a series of path analysis models in Mplus to determine the longitudinal associations between violence and suicidality. Results from the path analyses indicated that violence and suicidality mutually affect each other from adolescence into young adulthood. We found some evidence that the association between suicidality and violence was stronger for males compared to females, particularly in early and young adulthood. The current study confirms previous findings by demonstrating that violence is a risk factor for future suicide. We also extended the previous literature by demonstrating that a history of suicidality is associated with future risk for violence. Our findings highlight the importance of further integrating prevention efforts to reduce violence and suicidality during adolescence and early/young adulthood.     

Trauma‐Related Guilt Mediates the Relationship between Posttraumatic Stress Disorder and Suicidal Ideation in OEF/OIF/OND Veterans

Posttraumatic stress disorder (PTSD) and trauma‐related guilt are risk factors for suicidal ideation (SI) in veterans. Components of trauma‐related guilt were examined as serial mediators of the relationship between PTSD and SI. In a sample of 53 OEF/OIF/OND combat veterans, PTSD had an indirect effect on SI through a serial mediation chain of guilt cognitions, distress, and global guilt, suggesting that trauma‐related guilt via cognitions, distress, and global guilt is a pathway from PTSD to SI. Attention should be given to assessing and addressing trauma‐related guilt in veterans experiencing PTSD to prevent SI.     

Mindfulness Moderates the Association Between Perceived Burdensomeness and Suicide Ideation in Adults With Elevated Depressive Symptoms

A conceptual model in which the associations between perceived burdensomeness and suicide ideation, and between thwarted belongingness and suicide ideation, are moderated by mindfulness was examined. Participants were 218 undergraduates (mean age = 20.81) with moderate‐to‐severe depressive symptoms. Mindfulness significantly moderated the association between perceived burdensomeness and suicide ideation; participants with thoughts of burdensomeness experienced lower levels of suicide ideation if they were high, as opposed to low, in mindfulness. Mindfulness did not significantly moderate the association between thwarted belongingness and suicide ideation. Implications for intervention and elaboration of the interpersonal psychological theory of suicide are discussed.     

Dating Violence Victimization,Dispositional Aggression,and Nonsuicidal Self‐Injury among Psychiatrically Hospitalized Male and Female Adolescents

The objective of the current study was to characterize the association between dating violence victimization and dispositional aggression in predicting nonsuicidal self‐injury (NSSI) among psychiatrically hospitalized male and female adolescents. One hundred fifty‐five adolescents (ages 13–17) and their parents completed the Schedule for Affective Disorders and Schizophrenia for School‐Age Children clinical interview to assess NSSI and child abuse; adolescents completed self‐report measures of aggression and dating violence victimization (verbal, physical, and sexual). Dating violence victimization and NSSI were found to be highly prevalent among both males and females in this psychiatric inpatient sample. Two moderational models were supported, wherein dating violence was associated with NSSI in the context of elevated trait anger in males and indirect aggression in females. Findings suggest that helping victims of dating violence acquire skills to address certain forms of dispositional aggression may attenuate NSSI.     

Correlates of Suicide Stigma and Suicide Literacy in the Community

Public knowledge and attitudes toward suicide may influence help‐seeking for suicidality. This study aimed to identify correlates of suicide attitudes and knowledge. Australian adults were invited to complete an online survey, with 1,286 responders. Less exposure to suicide, older age, male gender, less education, and culturally diverse backgrounds were associated with poorer knowledge; while younger age, male gender, and culturally diverse backgrounds were associated with more stigmatizing attitudes toward people who die by suicide. The results suggest suicide literacy and stigma reduction programs would benefit community members, particularly males and individuals from culturally diverse backgrounds.
