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 explore risk and protective factors associated with suicidal ideation among law enforcement personnel.

The methodology employed is based on the “Best Evidence Synthesis” approach, whereby researchers systematically examine and integrate the most empirically sound available research on the topic under investigation.

Results of studies showed that the interaction of multiple risk factors had a cumulative effect in increasing the risk for suicidal ideation. In total, five prominent aspects of policing were associated with risk for suicidal ideation: organizational stress; critical incident trauma; shift work; relationship problems; and alcohol use and abuse. Studies also indicated that protective factors and preventative measures had stress‐buffering effects which decreased the impact of police stressors.

The model is limited because few studies have employed methodologically‐sound research designs to test risk and protective factors related to police suicide. This conceptual overview may facilitate theory development and provide directions for future research.

Law enforcement agencies which implement programs that assist police personnel in developing active coping styles, identify and access available social support systems, as well as utilize community‐based services may decrease risk for suicidal ideation. This review provides practical applications for law enforcement training, education, and program development.

The paper represents the most recent review of risk and protective factors related to suicidal ideation among police personnel. This integration of research provides police practitioners with an evidence‐based ecological framework that can be applied universally in police management settings.

The phenomenon of murder-suicide (aka. homicide-suicide) makes a sizeable impact on current public perceptions and policies regarding mental illness and risk for violence. However, within the past 25 years, our understanding of murder-suicide has remained relatively stable, and so has our relative inability to reliably predict and prevent it. The purpose of this paper is to propose pathways for furthering a cogent understanding of murder-suicide that may inform specific predictive and preventative practices.

Research literature regarding empirical and theoretical positions in the fields of murder-suicide, homicide, and suicide are reviewed and discussed.

While murder-suicide has many similarities to both homicide and suicide, no current theories of either alone have been successful in fully incorporating the phenomenon of murder-suicide. Theories specific to murder-suicide as a unique form of violence are in need of further research.

Developing and empirically testing theories of murder-suicide may lead to a vast and needed improvement of our understanding, prediction, and prevention of these tragedies.

Anecdotal accounts of suicide among temporary low-wage migrant workers in the UAE are numerous, but unofficial and qualitative accounts remain unexplored. This study aims to examine how the socio-environmental context can lead some low-wage migrants, irrespective of their nationality or culture, to contemplate suicide for the first time after arriving in the host country.

The findings draw from ten months of qualitative fieldwork (2015–2016) and in-depth interviews conducted with 44 temporary migrant workers from sub-Saharan Africa and South Asia, earning in the lowest wage bracket in Dubai. The study used a non-probabilistic, purposive sampling approach to select participants. Three criteria drove eligibility: participants had to reside in the UAE, be non-national and earn Dh1500 (US$408) or less a month. Otherwise, diversity was sought in regard to nationality, occupation and employer.

Eight (18%) of the 44 study participants interviewed admitted to engaging in suicidal thoughts for the first time after arriving in the UAE. The findings suggest that for low-wage migrants working in certain socio-environmental contexts, the religious, gendered or other cultural or group characteristics or patterns that may be predictors of suicide in migrants’ country of origin may become secondary or possibly even irrelevant when one is forced to survive under conditions that by most objective standards would be deemed not only oppressive but extremely exploitative and abusive.

This study contributes to understandings of how the emotional and psychological well-being of temporary foreign low-wage migrant workers can be impacted by the socio-environmental context of the host country. It is a first step in understanding the intimate thoughts of low-wage migrant workers on the topic of suicidality, furthering our understanding of suicidal ideation and the factors that can contribute to it.
