Interpersonal violence, alcohol use, and acquired capability for suicide

Acquired Capability for Suicide: An Evolutionary Concept Analysis

While virtually all suicide attempters experience ideations, not all who think about suicide will attempt or die by suicide. The ideation-to-action framework has led to new theories distinguishing suicide ideators from suicide attempters. The framework suggests that suicide progresses on a spectrum of thoughts and behaviors with different identifiers and explanations. The concept of acquired capability for suicide (ACS), conceptualized by the Interpersonal Psychological Theory of Suicide, is the first to explain the movement from ideation to action. This concept analysis of ACS is timely and relevant for greater clarification of the role ACS has in the movement from ideation to action. Rodgers' evolutionary concept analysis method is used. The six-step evolutionary method highlights the concept's attributes, antecedents, and consequences and provides a basis for further inquiry and development rather than a final definition.

Alcohol use disorder and risk of specific methods of suicide death in a national cohort

INTRODUCTION

Alcohol use disorder (AUD) is among the strongest correlates of suicide death, but it is unclear whether AUD status is differentially associated with risk of suicide by particular methods.

METHODS

The authors used competing risks models to evaluate the association between AUD status and risk of suicide by poisoning, suffocation, drowning, firearm, instruments, jumping, or other means in a large Swedish cohort born 1932-1995 (total N = 6,581,827; 48.8% female). Data were derived from Swedish national registers, including the Cause of Death Register and a range of medical registers.

RESULTS

After adjusting for sociodemographic factors and familial liability to suicidal behavior, AUD was positively associated with risk of suicide for each method evaluated (cumulative incidence differences: 0.006-1.040 for females, 0.046-0.680 for males), except the association with firearm suicide in females. AUD was most strongly associated with risk of suicide by poisoning. Sex differences in the effects of AUD and family liability were observed for some, but not all, methods. Furthermore, high familial liability for suicidal behavior exacerbated AUD's impact on risk for suicide by poisoning (both sexes) and suffocation and jumping (males only), while the inverse interaction was observed for firearm suicide (males only).

CONCLUSIONS

AUD increases risk of suicide by all methods examined and is particularly potent with respect to risk of suicide by poisoning. Differences in risk related to sex and familial liability to suicidal behavior underscore AUD's nuanced role in suicide risk. Future research should investigate targeted means restriction effectiveness among persons with AUD.

Embracing Emotional Pain: A Case Study of Adolescent Suicidality and Spirituality

BACKGROUND

Suicidality continues to be the second leading cause of adolescent death. Nurses are in a prime position to address the emotional pain associated with adolescent suicidality but report skepticism and discomfort. Moreover, spirituality is identified as a protective factor against suicidality, yet a gap exists related to exploring spirituality within the context of the emotional pain associated with adolescent suicidality. Building awareness of adolescents' spirituality and emotional pain associated with suicidality is essential to address nurse skepticism and discomfort.

AIMS

The purpose of this study was to explore young adults' experiences of suicide attempt(s) during adolescence in the context of spirituality using a case study application of participant narratives to Minton and Antonen's B.L.E.S.S. acronym.

METHOD

A multiple-case study design was used to provide an alternative perspective for understanding adolescent suicidality from a spiritual context. Reed's theory of self-transcendence and the B.L.E.S.S. acronym guided the analysis and interpretation. Convenience online sampling resulted in six adult participants who provided email narratives of their adolescent experiences. Email data collection was guided by Fritz and Vandermause. Analysis of participant narratives followed the protocol of Baxter and Jack.

RESULTS

Participant's narratives revealed self-transcendence that paralleled the five truths about emotional pain and spirituality inherent in the B.L.E.S.S. acronym.

CONCLUSION

This case study provides nurses a guide for counteracting the barriers of skepticism and stigma to promote help-seeking behavior associated with adolescent suicidality. Further research is needed for the application of the B.L.E.S.S. acronym with other population samples.

Depressive Symptoms Moderate the Association Between the Recent History of Alcohol Use Severity and Suicide Attempt History Among Adults in a Pretrial Jail Diversion Program

Background: Justice-involved individuals are at elevated risk for suicidal behavior; however, research examining risk for suicidal behavior in pretrial jail diversion programs (pretrial diversion) is limited. Aims: We aimed to test (1) associations between depressive symptoms and alcohol and drug use, and suicide attempt history (SAH), and (2) interactions between depressive symptoms and alcohol and drug use in relation to SAH among adults in an urban pretrial jail diversion program. Method: The design was cross-sectional, including self-report assessments and file reviews of historical information. Adults (N = 274; Mage = 33.72; 73.7% men; 52.6% non-Hispanic Black) completed assessments within two weeks of beginning the pretrial program. Results: Depressive symptoms were positively associated with SAH after adjusting for other covariates. The significant depressive symptoms by alcohol use interaction indicated that adults with low to average depressive symptoms evidenced a similar likelihood of SAH to those with high depressive symptoms when they also had elevated alcohol use scores. Limitations: We used cross-sectional self-report data. Conclusion: It may be important to conduct suicide risk assessments for justice-involved people who use alcohol even when depressive symptoms are low.

Substance Use Frequency Relates to Suicidal Ideation Through Perceived Burdensomeness and to Suicide Attempts Through Capability for Suicide

BACKGROUND

Although substance use has been linked to both suicidal ideation and suicide attempts, the factors underlying these relations remain unclear. The Interpersonal-Psychological Theory of Suicide (ITS) provides a framework for understanding how substance use may increase suicide risk. The purpose of the current study was to examine if frequency of substance use is indirectly related to suicidal ideation and suicide attempts through core ITS variables (i.e., burdensomeness, thwarted belongingness, and suicide capability).

METHODS

An online sample of Mechanical Turk workers (N = 365) completed measures assessing substance use frequency, burdensomeness, thwarted belongingness, suicide capability, suicidal ideation, and suicide attempts.

RESULTS

After controlling for relevant clinical and demographic covariates, substance use frequency was indirectly related to suicidal ideation through burdensomeness but not thwarted belongingness. Substance use frequency was indirectly related to suicide attempts through suicide capability only.

LIMITATIONS

The cross-sectional design precludes conclusions about the precise nature and direction of the relations examined. The use of a community sample limits generalizability to more severe substance using samples.

CONCLUSIONS

Results highlight the relevance of distinct ITS factors in the relation between substance use frequency and both suicidal ideation and suicide attempts. Results may inform specific targets for novel interventions aimed at reducing suicide risk among substance-using individuals.HighlightsSubstance use frequency was indirectly related to SI through burdensomeness.Substance use frequency was not indirectly related to SI through thwarted belongingness.Substance use frequency was indirectly related to SA only through suicide capability.

What Differentiates Prisoners Who Attempt Suicide from Those Who Experience Suicidal Ideation? A Nationally Representative Study

OBJECTIVE

Many people who think about suicide do not engage in suicidal behavior. Identifying risk factors implicated in the process of behavioral enaction is crucial for suicide prevention, particularly in high-risk groups such as prisoners.

METHOD

Cross-sectional data were drawn from a nationally representative sample of 17,891 prisoners (79% men) in the United States. We compared prisoners who attempted suicide (attempters; n = 2,496) with those who thought about suicide but never made an attempt (ideators; n = 1,716) on a range of established risk factors.

RESULTS

More than half (59%) of participants who experienced suicidal ideation had also attempted suicide. Violent offending, trauma, brain injury, alcohol abuse, and certain mental disorders distinguished attempters from ideators.

CONCLUSION

Our results fit within recent ideation-to-action theories that emphasize the role of a capability for suicide in the transition from thoughts to acts of suicide.

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 theoretically distinct points along the trajectory from suicidal thinking to behavior (i.e., desire, plans and preparations, suicide attempt) in a manner consistent with the Three-Step Theory and an ideation-to-action framework. The sample included 197 adult inpatients (60% male, 40% white) hospitalized due to ideation or a recent suicide attempt.

RESULTS

Psychological pain and fearlessness about death were associated with desire and plans and preparations for suicide. There were no significant differences in suicide risk correlates between ideators and attempters.

LIMITATIONS

The primary limitations of the current study relate to the cross-sectional design and the nature of the sample, which do not allow for inference of causal relations, or generalizability to outpatient and community samples or to individuals who die by suicide.

CONCLUSIONS

Psychological pain and fearlessness about death may function as transitional factors that are associated with the transition from desire to suicidal intent in psychiatric inpatients. Findings have important implications for clinical practice. Treatment interventions should reduce psychological pain, increase safety, and reduce access to means.

Interpersonal Risk Factors for Suicide in Cocaine Dependence: Association with Self-Esteem, Personality Traits, and Childhood Abuse

OBJECTIVE

Studies have linked cocaine dependence to suicidality. According to the Interpersonal Theory of Suicide, suicidal behavior becomes likely with the simultaneous presence of perceived burdensomeness (PB), lack of (or thwarted) belongingness (TB), and acquired fearlessness about death (FAD). Here, we examined personality and other variables, including depression, self-esteem, childhood abuse, and substance use, as predictors of these risk factors in cocaine-dependent individuals (CDs).

METHODS

Seventy CDs and 70 healthy controls (HCs) participated. We examined group differences in a group-by-sex analysis of variance and identified predictors of PB, TB, and FAD in stepwise regressions.

RESULTS

CDs exhibited elevated PB and TB but not FAD, compared to HCs. CDs also exhibited elevated harm avoidance, novelty seeking, depression, and lower self-esteem and reward dependence. Females reported elevated sexual abuse, harm avoidance, reward dependence, depression, but lower FAD, relative to males, among CDs and HCs. Among CDs, PB was predicted by lower self-esteem and greater emotional abuse; TB was predicted by lower self-esteem and reward dependence, as well as greater emotional and sexual abuse; and FAD was predicted by lower harm avoidance and greater physical abuse.

CONCLUSIONS

Interventions targeting suicidality in cocaine dependence should take into consideration self-esteem, personality traits, and childhood abuse.

Masculine gender-related personality traits and acquired capability for suicide

In most countries, substantially more men than women die by suicide, implicating masculine gender-related personality (MGP) traits as a risk factor for suicide. The Interpersonal Theory of Suicide posits that acquired capability for suicide (ACS) is needed to end one's life. To investigate MGP traits and ACS, college students (N = 149) completed measures of stoicism, sensation seeking, physical aggression, and ACS. For both genders, most MGP traits were associated with increased ACS. Physical aggression mediated relations between both stoicism and sensation seeking and ACS, but gender did not moderate these associations, suggesting similar patterns for men and women.

Evaluating the Interpersonal-Psychological Theory of Suicide among Latina Adolescents using Qualitative Comparative Analysis

The Interpersonal-Psychological Theory of Suicide (IPTS) has emerged as an empirically supported theory of suicide risk, yet few studies have utilized IPTS to examine the suicidal behaviors of Latina adolescents. In this study, we explore the cultural and developmental appropriateness, as well as the explanatory fit, of IPTS within a sample of Latina adolescents. Data for this project were drawn from qualitative interviews conducted with Latina adolescents with (n=30) and without (n=30) histories of attempted suicide. We employed a deductive qualitative approach to define and compare core constructs of IPTS (perceived burdensomeness, thwarted belongingness, and acquired capability), and then use qualitative comparative analysis to evaluate how core constructs were linked with the occurrence of a suicide attempt. Consistent with IPTS, perceived burdensomeness, thwarted belongingness, and acquired capability were present in 20 of the 30 adolescents who had attempted suicide, and absent in 22 of the 30 adolescents with no lifetime history of suicidal behaviors. Notably, alternative combinations of IPTS constructs were found in 10 cases of adolescents who attempted suicide, suggesting a need to adjust IPTS to fit the developmental and cultural contexts of Latina teens. Although our results suggest predominantly positive support for IPTS, participants varied in terms of how their experiences resonated with the conceptual definitions put forward by the theory. Ultimately, our findings point to the ways in which developmental tensions are exacerbated by broader sociocultural dynamics, contributing to a broader understanding of suicide risk among ethnic minority adolescents.

A Preliminary Test of the Interpersonal-Psychological Theory of Suicide in Women Seeking Shelter From Intimate Partner Violence

Women seeking shelter from intimate partner violence (IPV) are at greater risk of suicide ideation and attempts compared with women in the general population. A theoretically grounded understanding of suicide risk in shelter-seeking women is critical to improve assessment and management of suicide risk in this population. The interpersonal-psychological theory of suicide (IPTS) proposes that suicide ideation results from hopelessness about thwarted belongingness and perceived burdensomeness. However, suicide ideation does not progress to death by suicide unless one has acquired the capability for suicide (i.e., pain tolerance and fearlessness about death) via repeated exposure to painful and fearsome events. The present study provides a preliminary test of the IPTS in a sample of 134 women seeking shelter from IPV. First, we examined factors theoretically related to suicide ideation, demonstrating that only at high levels of hopelessness was perceived burdensomeness associated with suicide ideation. The study also examined factors theoretically related to the acquired capability for suicide (ACS), indicating that physical partner violence perpetration was associated with ACS. These findings suggest that perceived burdensomeness, particularly in the context of increased hopelessness, is important in the assessment and treatment of suicide ideation. Furthermore, violence perpetration may indicate greater risk of the capability to die by suicide among women seeking shelter from IPV.

An Exploratory Analysis of Violent Offending and the Acquired Capability for Suicide in Male Prisoners

Recently, the Interpersonal Theory of Suicide has offered some understanding as to why inmates are at a disproportionately high risk to die by suicide. The present study was designed to investigate how one aspect of the theory, the acquired capability for suicide, may differ between prison inmates with violent offenses versus those without. Data from 343 male prisoners within the Mississippi Department of Corrections were used to examine potential differences between these two groups on scales of the Acquired Capability for Suicide Scale. Contrary to the hypothesis that violent offenders would evidence higher levels of acquired capability, only the Spectator Enjoyment of Violence subscale was significantly different between the two groups, with nonviolent offenders producing higher scores. Potential explanations for these findings and implications for correctional mental health care providers are discussed.

Correlates of suicide ideation and behaviors among transgender people: A systematic review guided by ideation-to-action theory

Transgender people are at high risk for suicide ideation, attempts, and deaths compared to the general population. Several correlates of suicide ideation and attempts have been identified empirically to understand this increased risk. However, few attempts have been made to systematically review this literature. Further, a theory to understand and identify targetable factors for intervention has rarely been applied to this population. In the first systematic review guided by ideation-to-action frameworks of suicide, we systematically reviewed the literature from January 1991 to July 2017 regarding correlates of suicide ideation, attempts, and deaths among transgender people. To be included in the review, articles must have been reported in English, reported on empirical data, included a sample or subsample of transgender people, and reported separately on correlates of suicide ideation, attempts, or deaths. Two independent reviewers searched three major databases, references of included articles, and unpublished literature, which produced 45 articles for review. The review suggested that ideation-to-action frameworks would be worth investigating within this population, with attention to sources of psychological pain, social connectedness, and capacity/capability for suicide unique to this population. Additionally, other aspects of cultural identity were often studied (e.g., race, religion), suggesting the need to understand intersectionality of identities among transgender people and their effects on suicide risk. Finally, the review highlighted important limitations of the literature, namely measurement of suicide ideation and attempts and sampling method, which future work should seek to improve.

The interpersonal theory of suicide: A systematic review and meta-analysis of a decade of cross-national research

Over the past decade, the interpersonal theory of suicide has contributed to substantial advances in the scientific and clinical understanding of suicide and related conditions. The interpersonal theory of suicide posits that suicidal desire emerges when individuals experience intractable feelings of perceived burdensomeness and thwarted belongingness and near-lethal or lethal suicidal behavior occurs in the presence of suicidal desire and capability for suicide. A growing number of studies have tested these posited pathways in various samples; however, these findings have yet to be evaluated meta-analytically. This paper aimed to (a) conduct a systematic review of the unpublished and published, peer-reviewed literature examining the relationship between interpersonal theory constructs and suicidal thoughts and behaviors, (b) conduct meta-analyses testing the interpersonal theory hypotheses, and (c) evaluate the influence of various moderators on these relationships. Four electronic bibliographic databases were searched through the end of March, 2016: PubMed, Medline, PsycINFO, and Web of Science. Hypothesis-driven meta-analyses using random effects models were conducted using 122 distinct unpublished and published samples. Findings supported the interpersonal theory: the interaction between thwarted belongingness and perceived burdensomeness was significantly associated with suicidal ideation; and the interaction between thwarted belongingness, perceived burdensomeness, and capability for suicide was significantly related to a greater number of prior suicide attempts. However, effect sizes for these interactions were modest. Alternative configurations of theory variables were similarly useful for predicting suicide risk as theory-consistent pathways. We conclude with limitations and recommendations for the interpersonal theory as a framework for understanding the suicidal spectrum. (PsycINFO Database Record

Belongingness and Burdensomeness in Adolescents: Slovene Translation and Validation of the Interpersonal Needs Questionnaire

The Interpersonal Needs Questionnaire (INQ) for assessing thwarted belongingness (TB) and perceived burdensomeness (PB) has not been validated with community adolescents. We translated and administered the INQ to 307 Slovenian adolescents twice over 2-3 months and found that the 15-item version (INQ-15) did not fit without modification. TB and PB scales correlated with concurrent and later suicide ideation and lifetime suicide attempt history. The latent PB factor was associated with concurrent and later ideation controlling for TB, age, gender, depressive symptoms, binge drinking, and peer victimization. Suicide ideation and binge drinking were independently related to attempt history. Assessing and intervening on PB and binge drinking may be promising approaches to suicide prevention with community adolescents.

A test of the interpersonal-psychological theory of suicide among arrested domestic violence offenders

Little is known about risk factors for suicide ideation and attempts among domestic violence offenders. Guided by the interpersonal-psychological theory of suicide, this cross-sectional study examined risk factors for suicide ideation and attempts among 312 men and 84 women arrested for domestic violence and mandated to attend batterer intervention programs. Men reported greater capability for suicide, but no gender differences were found in perceived burdensomeness and thwarted belongingness. After controlling for correlates of suicide ideation, perceived burdensomeness-but not thwarted belongingness or its interaction with perceived burdensomeness-associated with suicide ideation. Suicide attempters exhibited greater perceived burdensomeness, drug use and problems, borderline personality disorder symptoms, depressive symptoms, and suicide ideation, but not capability for suicide, than nonattempters. Gender did not moderate the associations of the IPTS constructs with suicide ideation and attempts. These findings parallel tests of the interpersonal-psychological theory in other samples. Additional work is needed to identify factors that distinguish risk for suicide ideation from risk for suicide attempts among domestic violence offenders.

Dimensionality, psychometric properties and population-based norms of the German version of the Revised Acquired Capability for Suicide Scale (ACSS-FAD)

The aim of the present study was the validation of the Acquired Capability for Suicide Scale-Fearlessness about Death (ACSS-FAD) in a large population sample to further establish its reliability and validity, and to provide norm values. We assessed the ACSS-FAD, measures of depression, history of suicidal behavior, and anxiety in a representative sample of the German population (N=2513) and analyzed its dimensionality, invariance across sex and construct validity by means of confirmatory factor analysis, correlational analysis and analysis of variance. The one-factorial structure achieved satisfactory model fit after introducing several correlating error terms. Across sex, partial scalar invariance could be established. Depression and anxiety showed negative associations with the ACSS-FAD while no relation with past suicidal behavior was found. Because mean scores in the ACSS-FAD were affected by sex and age group, sex and age-specific norm values were calculated. Our findings support the one-factorial structure of the ACSS-FAD when the measurement model is slightly modified, pointing out the need of revising the wording of some items. The validity of the measure should be further examined in clinical samples.
