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.

The purpose of this paper is to examine the role of suicide-related mental imagery in suicidal behavior. It was hypothesized that greater frequency and vividness of suicide-related imagery would be associated with more suicidal behaviors, and acquired capability for suicide was expected to mediate this relationship. Hypotheses were tested by surveying 237 undergraduate students (59 percent female; mean age=20) who completed self-report measures that assessed suicidal cognitions, acquired capability for suicide, and history of self-harm behaviors.

Hypotheses were tested by surveying 237 undergraduate students (59 percent female; mean age=20) who completed self-report measures that assessed suicidal cognitions, acquired capability for suicide, and history of self-harm behaviors.

Results suggested that frequency and vividness of suicide-related imagery were positively correlated with suicidality. Acquired capability was not related to study variables; thus additional mediational analysis was unwarranted.

Few studies have examined suicidal imagery and how it relates to actual self-harm behavior. The current study provides an exploratory view of features of imagery related to suicidal thoughts; findings imply that understanding mental imagery may play an important role in clinical risk assessment and treatment for suicidality.

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.

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.

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.

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.

The therapeutic community (TC) is a widely used treatment approach for substance use disorders. Several psychological theories have been used to explain its processes but have put less emphasis on the specific contributions of the person’s cognitive resources. This paper aims to offer a theoretical conceptualization using the locus-of-hope theory which expounds on the person’s goal-directed thinking and how it bolsters the TC process.

This paper reviewed contemporary theoretical perspectives on TCs and studies on locus-of-hope theory to provide arguments for locus-of-hope’s utility in understanding TCs. From this review, this paper discusses a formal conceptualization of TCs using the locus-of-hope model.

In this conceptualization, the authors explained that the TC becomes a co-agent in the person’s goal-pursuit by strengthening the individual’s beliefs regarding one’s capability to develop goals together with the will and strategies to attain these important recovery goals. The person’s hopeful thinking boosts the TC protocols in a dynamic fashion.

This paper offers a locus-of-hope perspective that considers the person’s contributions in bolstering the TC process. Reflections on clinical and research implications were provided. This paper aids further in unboxing of the TC.

This study was the first to examine two related constructs within the context of leadership. Stoicism is an ancient philosophy offering practical advice for a virtuous and eudaemonic life. As a method to examine one’s emotional experiences (Sellars, 2006), leaders such as Roman Emperor Marcus Aurelius and Teddy Roosevelt (Aurelius, ca. 160 A.D., 2002) practiced Stoicism, yet mentions of it within the field of leadership research have been scant. Leadership academics contrast desirable emotional intelligence behaviors with Stoicism (Grewal & Salovey, 2005; Mayer et al., 2008). Regardless, these two constructs are both concerned with effectively managing emotions, practicing self-awareness, high levels of motivation, and sensitivity to the expression of emotion in others (Goleman, 2005; Pigliucci, 2017; Salzgeber, 2019).

Undergraduate students in a leadership minor (_N_ = 445) at a public university completed the Emotional and Social Competency Inventory - University and the Liverpool Stoicism Scale. Analysis included a description of assessment results, an examination or the relationship between variables and differences in participant’s scores based on race, gender, and age. Stoicism and emotional self-awareness showed a moderate, statistically significant negative correlation (_r_ = - 0.391, _p_ = .05). A low, statistically significant negative relationship was reported between stoicism and the relationship management competency of teamwork (p = .003, r = -.018), and a low statistically significant positive relationship between self-management competencies, adaptability (p = .043, r = .189) and emotional self-control (p = .039, r = .192). Student’s Stoicism scores were significantly correlated with gender (_t_(113) = 2.479; _p_ = .015, _d_ = .564).

The research findings provided baseline statistics for continued exploration of Stoicism within the context of leadership. Future research that better aligns with the original doctrines of the philosophy is recommended, particularly in the interest of leadership development.

Non-suicidal self-injury (NSSI) is distinguishable from suicide attempts (SAs) on a number of psychological and motivational factors. However, in corrective services settings, NSSI and SA are not clearly distinguished in assessment impacting on intervention. The purpose of this paper is to examine if any attributes differentiate lifetime history of SA+NSSI, NSSI and SA presentations in inmates who had recently been assessed in custody by a risk intervention team.

A comprehensive clinical assessment and file review was conducted with 87 male inmates (including a no self-injury control group) in two large correctional centres in New South Wales, Australia, to determine if three self-injury groups differ from the control group and if the three self-injury groups differ from each other across a range of static, trait, environmental and clinical characteristics.

The SA+NSSI group was most different from the control group (27/59 variables), and from the SA group (10/59 variables), predominantly across trait and clinical correlates. The SA group was least different from the control group (2/59 variables: suicide ideation, childhood physical abuse).

It was found that the presence of SA+NSSI history is an indicator of increased psychopathology. A history of SA only appears not readily associated with psychopathology. The self-injury subgroups reflected different clinical profiles with implications for risk assessment and treatment planning.
