How do sexual and gender minority people acquire the capability for suicide? Voices from survivors of near-fatal suicide attempts

Despite well-documented disparities by sexual and gender minority (SGM) status in suicide attempt and mortality rates, few studies have investigated the lived experiences that contribute to SGM people’s disproportionate risk of suicide. Having a history of at least one near-fatal (or medically serious) suicide attempt serves as a proxy for suicide mortality, but no known[…]

Diminished responses to bodily threat and blunted interoception in suicide attempters

Psychological theories of suicide suggest that certain traits may reduce aversion to physical threat and increase the probability of transitioning from suicidal ideation to action. Here, we investigated whether blunted sensitivity to bodily signals is associated with suicidal action by comparing individuals with a history of attempted suicide to a matched psychiatric reference sample without[…]

The frequency and subjective impact of painful and provocative events on the acquired capability for suicide

Background: Leading theoretical explanations for suicide state that for suicide death to occur, a person must have sufficient capability to enact an attempt. Exposure to painful and provocative events is hypothesized to play an important role in acquiring the capability for suicide over a lifetime. Unfortunately, assessment tools for painful and provocative events have focused solely[…]

Rising longitudinal trajectories in suicide rates: The role of firearm suicides rates and firearm legislation

Firearms account for approximately half of all US suicide deaths each year despite being utilized in only a small minority of suicide attempts. We examined the extent to which overall suicide rates fluctuated relative to firearm and non-firearm suicide rates across a period of 16years (1999-2015). We further tested the notion of means substitution by[…]

Body investment as a protective factor in the relationship between acquired capability for suicide and suicide attempts

Acquired capability for suicide is associated with increased suicide risk and behaviors, but little research has examined factors that may qualify this relationship. Body investment is proposed as one such factor, as it may engage self-preservation instincts and serve as a buffer to capability for suicide. It was expected that facets of body investment (body[…]

Suicide risk and restricted emotions in women: The diverging effects of masculine gender norms and suicide capability

This study investigated whether gender moderated the association between masculine socialization pressures of restrictive emotionality and suicide risk through suicide capability (i.e., fearlessness about death). A sample of inpatients admitted for recent suicidality (n = 194) completed validated measures of restrictive emotionality, fearlessness about death, and current suicide risk. A moderated mediation effect was found opposite[…]

Comparison of perceived burdensomeness, thwarted belongingness, capability for suicide, and suicidal ideation among heterosexual and sexual minority individuals in Mississippi

This study sought to compare risk factors for suicidal ideation among heterosexual and sexual minority college students from a previously understudied conservative region of the United States. Suicidal ideation, thwarted belongingness (TB), perceived burdensomeness (PB), and capability for suicide were examined. It was found that PB was significantly higher among sexual minorities than heterosexual individuals,[…]

Understanding the transition from suicidal desire to planning and preparation: Correlates of suicide risk within a psychiatric inpatient sample of ideators and attempters

Background: There is a clear need to better understand the trajectory from suicidal ideation to enactment of lethal suicidal behavior. Identification of factors that promote desire and the transition to intent and behavior is critical for the advancement of theory, risk formulation, and prevention. Method: In this cross sectional study, correlates of suicide risk were examined at[…]

Do suicidal behaviors increase the capability for suicide? A longitudinal pretest-posttest study of more than 1,000 high-risk individuals

Despite the prominence of the capability-for-suicide construct in suicide research, fundamental hypotheses about its nature and development remain largely untested. In this study, we tested the primary mechanism proposed to account for its development: habituation to painful or provocative events. More than a thousand adults were recruited worldwide from online suicide, self-injury, and mental health[…]

Validation of the German capability for suicide questionnaire (GCSQ) in a high-risk sample of suicidal inpatients

The German Capability for Suicide Questionnaire (GCSQ) was developed to measure fearlessness of death and pain tolerance – two constructs central to the Interpersonal Theory of Suicide. Initial scale development, definition of the factor structure and confirmation of the two-dimensional factor structure was performed in samples suffering from relatively low levels of suicide ideation/behavior. The[…]
