The interpersonal theory of suicide proposes that fearlessness about death, one aspect of the capability for suicide, may explain men’s greater risk for death by suicide. The purpose of this paper is to examine whether violence perpetration and victimization would mediate the relation of gender with fearlessness about death in suicidal psychiatric inpatients.

The current study used a cross-sectional survey design in a sample of 196 psychiatric inpatients admitted for suicide risk.

Men endorsed greater fearlessness about death compared to women. The relation of gender with fearlessness about death was partially mediated by violence perpetration, but not victimization. Violence perpetration may play a more central role in the development of fearlessness about death, the capability for suicide, and the transition from suicide ideation to action compared to violence victimization.

The current study was cross-sectional and not able to definitively answer questions about the development of the capability for suicide. Future research must examine how fearlessness about death evolves over time.

Suicide risk assessment should include history of violence perpetration, as this may better identify those who may be at greater risk for suicide due to greater fearlessness about death.

The current study adds to the growing literature that aims to understand variables that explain the transition from suicide ideation to action.

The interpersonal theory of suicide proposes that an individual must acquire the capability for suicide to carry out a near-lethal or lethal suicide attempt. This capability develops via habituation in response to painful and provocative life events. Some individuals might be more vulnerable to developing the capability for suicide because they habituate more quickly to stimuli. The purpose of this paper is to examine the relations between the rate of physiological habituation and acquired capability, proxies for acquired capability, and acute risk factors for suicide.

Depressed, suicidal individuals completed self-report assessments and a startle reflex task assessing the rate or speed of physiological habituation in response to repeated bursts of white noise.

Slower habituation was associated with hopelessness and negative stressors. The rate of habituation was not associated with acquired capability.

The current study informs the understanding of how physiological habituation is related to suicide risk factors.

Firearms account for the majority of suicide deaths in the US military and general population. The percentage of suicides resulting from firearms is higher in the military, however, and as such, the ratio of non-lethal to lethal suicide attempts is lower in the military than in the general population. In 2013, Congress passed the National Defense Authorization Act, which facilitated a Department of Defense (DoD) shift toward allowing commanding officers and clinicians to inquire about personal firearms with service members perceived as being at risk and also began giving free cable locks to firearm-owning military personnel. The purpose of this paper is to provide a preliminary understanding of the effectiveness of this change, the authors examined trends in firearm suicide attempts within the US military and general population from 2010 to 2015.

Data on non-lethal and lethal suicide attempts overall and within specific methods were extracted from the Department of Defense Suicide Event Report and the Centers for Disease Control and Prevention’s Web-based Injury Statistics Query and Reporting System (2011–2015).

Contrary to expectations, firearms were not utilized in a smaller proportion of suicide attempts within the military post-law change. Consistent with expectations, however, the ratio of non-lethal to lethal suicide attempts increased, particularly after the change in law, with the ratio in the military converging somewhat with that of the general population.

Overall, results were mixed, with only limited and tangential evidence that the change in law has proven effective. More precise data collection will be required in order to fully evaluate such laws.

The purpose of this paper is to provide a review of law enforcement suicide research from 1997 to 2016.

The PRISMA systematic review methodology was implemented. A SCOPUS search identified a total of 97 documents. After applying all exclusion criteria, the results included a list of 44 articles in the review.

Overall, studies investigating law enforcement suicide rates show conflicting results, with some studies showing lower suicide rates among law enforcement, some showing higher rates, and some showing no difference to comparison populations. Recurring research themes were lack of an appropriate comparison group, and small statistical power, particularly for minority and female officers. Stressors related to suicide among police included lack of organizational support, traumatic events, shift work, stigma associated with asking for help, or problems associated with fitting in with the police culture. Problems associated with domestic relationships and alcohol use were commonly mentioned as precursors to suicide or as correlates of suicidal ideation and were hypothesized to arise from stressful working conditions.

Some limitations in law enforcement suicide research include the lack of theory, under-reporting of suicides, and guarded survey responses from police officers. Future directions in police suicide research include investigating etiological factors such as past adverse life and family experiences, social-ecological variation in suicide, or differences in suicide rates within the law enforcement occupation.

Police work, given chronic and traumatic stress, lack of support, danger, and close public scrutiny is a fertile occupation for increased suicide risk. Awareness of the scope of the problem and associated risk factors can help to initiate prevention programs.

This paper provides a long-term review of literature regarding police suicidality, with suggestions for research and prevention.

Recent reports raise suicidality among asylum seekers as a pertinent issue in current Australian offshore detention centres. However, knowledge on the nature of the suicidality in these centres is very limited. The purpose of this paper is to explore in depth how suicidality arises and develops in offshore detention centres.

A single case study approach was used.

This case study presents the findings on the suicidal process of an asylum seeker who attempted suicide three times while in Nauru Regional Processing Centre, the last of which being a near-lethal one. The prolonged mandatory detention, together with lack of clarity about the timeframes of detention and constant postponing of the legal processes were identified as the main factors driving the suicidal intent. The suicidal behaviour escalated from an interrupted attempt to a near lethal one within two years, which signals lack of adequate suicide prevention within detention.

The resources for mental health being limited in Nauru, it is likely overall changes in refugee status processing may be a more effective suicide prevention strategy rather than implementation of other additional measures.

Studies in offshore processing facilities have been scarce due to barriers for researchers to access the detention centres. This study offers a unique insight into suicidality in this hard to reach population.

Despite evidence that violent daydreaming is a correlate of suicidal ideation, no research has examined the mechanisms underlying this association. The interpersonal theory of suicide may provide insight. This theory postulates that individuals with high suicidal desire experience intractable feelings of perceived burdensomeness (PB) and thwarted belongingness (TB). Violent daydreaming may fuel negative attitudes toward others and oneself and turn attention away from loved ones, thereby increasing feelings that one is a burden on others (PB) and socially disconnected (TB). However, no studies have tested TB and PB as explanatory mechanisms. The purpose of this paper is to examine the relationships between violent daydreaming, PB, TB, suicidal ideation, and depression in two samples (n=818).

Study 1 was comprised of general undergraduates, and Study 2 selected for undergraduates with a history of ideation. Self-report measures were administered and indirect effects analyses were conducted.

In both studies, violent daydreaming was associated with increased feelings of PB, TB, and ideation severity. Consistent with the interpersonal theory, TB and PB were significant parallel mediators of the relationship between violent daydreaming and suicidal ideation, beyond sex and age. In contrast to Study 1, results were no longer significant in Study 2 after accounting for depression.

This was the first study to test TB and PB as mechanisms underlying the relationship between violent daydreaming and suicide risk. Findings highlight the importance of monitoring and addressing violent daydreams and interpersonal functioning throughout treatment to mitigate risk.

Research indicates that a link exists between resting heart rate (RHR) and various forms of antisocial, violent and criminal behavior among community and criminal samples. However, the relationship between RHR and engagement in aggressive/violent encounters among law enforcement has not yet been examined. The purpose of this paper is to examine the link between RHR and engagement in violent encounters using prospective longitudinal data on a sample of law enforcement officers in the USA.

Negative binomial regression, Kaplan-Meier survival analysis and Cox hazard regressions are conducted using a sample of 544 police officers to determine if there a relationship between RHR and engagement in violent encounters by law enforcement, even when controlling for demographics, biological and social covariates.

Results indicate that higher RHR is associated with an increased risk of officers engaging in a violent altercation, as measured by the number of arrests for suspects resisting arrest with violence, even after controlling for all other relevant factors.

This study was the first to examine police officers RHR levels and its associated with violent altercations during arrest using a rigorous statistical methodology.

This brief narrative seeks to capture the 12-year relationship between the author and V. LeRoy Nash, who at 94 has been the oldest death row prisoner in the United States since 1996. LeRoy's life includes many killings, and over 71 years in prison, before Johnson and Nash developed this unique father–son love relationship.

Men make war; women make peace. Men make war; women make children. Men make war because women make children. Because men make war, women make children. Women make peace because they make children.

Critical occupations refer to professions in which workers perform critical duties to protect and serve the public; the nature of these jobs often exposes workers to events and conditions that critically impact their mental and physical well-being. In addition to the traumatic experiences part and parcel to the job, characteristics of these critical occupations – long work hours, nonstandard schedules, dangerous tasks, and a physically demanding work environment – contribute additional stressors. Yet, many workers in these occupations thrive despite the risks. Given the stressful conditions of critical occupations and potential for adverse individual and familial outcomes, it is important to consider why individuals would choose to work in critical occupations, why they might respond differently during stressful work-related events, and why some workers are particularly resilient. We posit that personality research offers intriguing insights into career selection, coping, and resilience for workers in critical occupations. Examining factors that reduce risk and promote resilience for these multiple-stressor occupations has the potential to inform research and policies that better meet the needs of employees and their families.
