Predictors of suicide attempt status: acquired capability, ideation, and reasons

Development and Validation of the Fearlessness About Suicide Scale

Recent work has identified fearlessness about suicide, rather than fearlessness about death, as more theoretically relevant in the assessment of capability for suicide and thus a more appropriate construct of measurement. The aim of the current project was to develop and validate a scale specifically assessing fearlessness about suicide. Across two studies, support for a 7-item, single-factor structure of the Fearlessness About Suicide Scale (FSS) emerged. The FSS factor structure demonstrated a good fit in the first study and was replicated in the second study. Measurement invariance was examined across those identifying as men and women and found to be comparable. The FSS also demonstrated test-rest reliability and good convergent and divergent validity in community and undergraduate samples. Overall, findings indicate that the FSS has a replicable factor structure that generalizes across those identifying as men and women and may better assess components of capability for suicide than existing scales.

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.

Theory of mind and suicide ideation and attempt in adolescent inpatients

BACKGROUND

Suicide ideation and attempt are alarmingly prevalent in adolescents, and even more so for youth in psychiatric settings. Interpersonal factors have been emphasized as important in the etiology and maintenance of suicide ideation and attempt in adolescents. Evaluating social cognitive deficits offers important insight into processes underlying interpersonal problems associated with suicide ideation and attempt; however little social-cognitive research has been conducted in this area. The aim of the current study was to explore the relation of theory of mind (ToM) impairments and suicide ideation and attempt among adolescent inpatients.

METHODS

A sample of 391 adolescent inpatients completed measures on ToM, suicidal ideation and attempt, clinical symptoms and sociodemographics.

RESULTS

Binary logistic regression analyses revealed significant relations between excessive ToM (hypermentalizing) and two suicide outcome variables (suicide ideation in the past four weeks, suicide attempt in the past year), while covarying for sociodemographics and multiple clinical symptom scales.

CONCLUSIONS

Excessive ToM, or over-attributing the mental/emotional states of others, appears to share a salient relation to recent suicidal thoughts and behavior in adolescent inpatients. Current findings may indicate that interventions incorporating social cognitive components (e.g., Mentalization Based Therapy and Cognitive Behavioral Therapy) may be of promise to treating youth with suicidal thoughts and behaviors and excessive ToM.

LIMITATIONS

The current study uses cross-sectional data and discrepancies exist in time periods assessed by primary measures.

Do suicide attempters and suicide ideators differ in capability for suicide?

Suicide ideation is a prerequisite for suicide attempts. However, the majority of ideators will never act on their thoughts. It is therefore crucial to understand what differentiates those who consider suicide from those who attempt suicide. The aim of this study was to investigate the role of different aspects of capability for suicide (fearlessness about death, subjective pain tolerance, objective pain persistence) in differentiating suicide ideators from suicide attempters, single attempters from multiple attempters and recent attempters from distant attempters. A total of 308 psychiatric inpatients (53.6% female; age: M=36.92, SD=14.30) suffering from suicide ideation with or without lifetime suicide attempts were compared regarding fearlessness about death, subjective pain tolerance and objective pain persistence (assessed with a pressure algometer). No differences in fearlessness about death, subjective pain tolerance and objective pain persistence were found in suicide ideators vs. attempters, single vs. multiple attempters and recent vs. distant attempters. It might be presumed that fearlessness about death, subjective pain tolerance and objective pain persistence do not offer useful information for the differentiation between suicide ideators and attempters, however, there are several limitations to take into account. Further effort is needed to understand more clearly what differentiates suicide ideators from suicide attempters.

Differentiating Suicide Attempters from Suicide Ideators: The Role of Capability for Suicide

This study examined whether different components of capability for suicide (i.e., fearlessness about death, pain tolerance, pain insensitivity, preparation for suicide, suicide plan, and courage), as well as painful and provocative events, nonsuicidal self-injury, depressive symptoms, and hopelessness, could distinguish between suicide attempters, suicide ideators, and non-suicidal controls. A total of 930 Chinese adolescents completed questionnaires, and a multinomial logistic regression was conducted to identify factors that could distinguish among the 3 groups. We found that higher levels of pain tolerance, more detailed suicide plans, more positive attitudes towards suicide, as well as more painful and provocative experiences and more severe depressive symptoms were positively associated with increased likelihood of the engagement in both suicide ideation and suicide attempts. Only nonsuicidal self-injury increased the likelihood of falling in the suicide attempt group as compared to the suicide ideation group. Findings of this study emphasize the role of nonsuicidal self-injury in intervening suicidality.

Health-Care Workers’ Perception of Patients’ Suicide Intention and Factors Leading to It: A Qualitative Study

This study explored health-care workers’ perception of patients’ suicide intention and their understanding of factors leading to particular interpretations. Semistructured face-to-face in-depth interviews were conducted with 32 health-care workers from a general hospital in Klang Valley, Malaysia. Interview data were transcribed verbatim and analyzed using the interpretative phenomenological analysis. The health-care workers were found to have four types of perceptions: to end life, not to end life, ambivalence about intention, and an evolving understanding of intention. Factors leading to their perceptions of patients’ suicide intention were patient demographics, health status, severity of ideation/attempt, suicide method, history of treatment, moral character, communication of suicide intention, affective/cognitive status, availability of social support, and health-care workers’ limited knowledge of patients’ condition/situation. Insufficient knowledge and negative attitudes toward suicidal patients led to risk minimization and empathic failure, although most health-care workers used the correct parameters in determining suicide intention.

Suicide Evaluation in the Pediatric Emergency Setting

Suicide is 1 of the top 3 leading causes of death in the pediatric population and a serious public health concern. There are evidence-based screening tools for suicide in the pediatric population; however, predicting suicide risks can be a difficult task. The emergency department is an essential source of mental health care for youths and can serve as an important opportunity for suicide screening and subsequent targeted interventions and resource management. More research is needed in emergency department-based screening algorithms and evidence-driven interventions in the pediatric population.

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
