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.

Warning signs for suicide attempts in psychiatric inpatients: Patient and informant perspectives.

OBJECTIVE: Warning signs can help prevent suicide attempts and death. It is important to develop an evidence base for warning signs that considers both self-perspectives (i.e., those at risk for suicide) and informant-perspectives (i.e., those who observe individuals at risk for suicide). METHODS: A questionnaire assessing a diverse set of 80 potential warning signs ("present in the minutes, hours, or days before the suicide attempts") was developed based on literature searches, lived experience consultations, and the American Association of Suicidology (AAS) expert consensus list. This questionnaire was administered to two samples: psychiatric inpatients who had attempted suicide (n = 476), and informants identified as friends, family, or caretakers of patients (n = 120). RESULTS: Hopelessness, anxiousness, and unbearable pain were each endorsed as warning signs by >80% of inpatients and informants. Warning signs were similar across patient and informant perspectives, and across sociodemographic and clinical characteristics. Some AAS warning signs were endorsed by few patients and informants (risky behaviors, alcohol or drug use, seeking revenge) and may warrant re-evaluation. CONCLUSIONS: Findings are consistent with models of suicide risk emphasizing pain, hopelessness, and anxiousness. Existing lists of warning signs may benefit from revision as the evidence base continues to develop.

"Psychotherapy in the Pressure Cooker": A Systematic Review of Single Session Psychosocial Interventions in Emergency Departments for Suicide-related Thoughts or Behaviors.

OBJECTIVES: Up to 20% of individuals who die by suicide have visited an emergency department (ED) within 4 weeks of their death. Limited guidance is available regarding the modification of clinical outcomes following a psychosocial intervention in the ED for pediatric and adult populations. METHODS: A systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines was conducted to identify studies focused on single-session psychosocial interventions for pediatric and adult patients experiencing suicide-related thoughts or behaviors (SRTB) in the ED. Two reviewers independently screened articles identified using the key terms suicide/self-harm, emergency department, and interview. Medline, PubMed, Embase, PsycINFO, CINAHL, and CENTRAL were searched from inception to August 2018. RESULTS: After screening 3234 abstracts, 29 articles were selected for full-text review and 14 articles, representing 8 distinct studies (N=782), were included. A high level of heterogeneity was present in the included articles, with 7 randomized-controlled trials, 2 nonrandomized-controlled trials, 2 cohort studies, 2 observational studies, and 1 feasibility study. Most of the included studies focused on adolescents (6 articles) or military veterans (7 articles). Strong statistical evidence of ED interventions improving outpatient service linkage was supported (χ2: 81.80, P<0.0001, 7 studies). CONCLUSIONS: The findings of this study suggested promising outcomes for patients presenting to the ED with SRTB who receive a single-session psychosocial intervention. All of the studies that measured such outcomes found significantly increased follow-up care in the intervention arm. Further research is needed to strengthen the evidence base, provide better patient representation, and improve our understanding of the mechanisms by which the psychosocial intervention for SRTB in the ED ameliorates patient outcomes (CRD42020156496).

Identifying suicide ideation in mental health application posts: A random forest algorithm.

The growing use of digitized mental health applications requires new reliable early screening tools to identify user suicide risk. We used a lexicon-based random forest machine learning algorithm to predict suicide ideation scores from 714 online community text posts from December 2019 to April 2020. We validated predicted scores against expert-rated suicide ideation scores. The algorithm-predicted scores offered high validity and a low error rate and correctly identified 95% of expert-rated high-risk suicide ideation posts. Our findings highlight a potential new method to detect suicidal ideation of digital mental health application users.

Mental Disorders and Beyond in the Quest to Understand Suicide: A Reply to Joiner and Robison.

We reply to the thoughtful commentary by Joiner and Robison (this issue) about the documentary Robin's Wish. Joiner and Robison suggest that a major depressive episode may have been a proximal cause of Robin Williams' suicide, but that stigma surrounding mental illness led the documentary to eschew a role for depression. We find this perspective compelling and important. Mental illness can be an important cause of suicide, and stigma can harm our ability to understand and treat mental illness and suicide risk. As a complementary perspective, we discuss research and theory suggesting that mental illness does not explain all deaths by suicide. We present research and theory suggesting that suicide is motivated by pain and hopelessness, and that pain and hopelessness can be caused not only by mental illness but by other factors such as overwhelming interpersonal struggles or loss, seemingly insurmountable financial problems, chronic medical conditions, and systematic discrimination and persecution. Finally, we reaffirm Joiner and Robison's belief that understanding and preventing suicide requires the pursuit of accurate knowledge, unburdened by stigma that can harm progress and people.

Examining protective factors for substance use problems and self-harm behavior during adolescence: A longitudinal co-twin control study.

Sports participation, physical activity, and friendship quality are theorized to have protective effects on the developmental emergence of substance use and self-harm behavior in adolescence, but existing research has been mixed. This ambiguity could reflect, in part, the potential for confounding of observed associations by genetic and environmental factors, which previous research has been unable to rigorously rule out. We used data from the prospective, population-based Child and Adolescent Twin Study in Sweden (n = 18,234 born 1994-2001) and applied a co-twin control design to account for potential genetic and environmental confounding of sports participation, physical activity, and friendship quality (assessed at age 15) as presumed protective factors for adolescent substance use and self-harm behavior (assessed at age 18). While confidence intervals widened to include the null in numerous co-twin control analyses adjusting for childhood psychopathology, parent-reported sports participation and twin-reported positive friendship quality were associated with increased odds of alcohol problems and nicotine use. However, parent-reported sports participation, twin-reported physical activity, and twin-reported friendship quality were associated with decreased odds of self-harm behavior. The findings provide a more nuanced understanding of the risks and benefits of putative protective factors for risky behaviors that emerge during adolescence.

A Longitudinal Study of Correlates, Discharge Disposition, and Rate of Re-presentation to Emergency Services of Adults who Engage in Non-suicidal Self-injury.

OBJECTIVE: In DSM-5, non-suicidal self-injury (NSSI) and suicide attempts (SA) are classified as distinct disorders in the section of conditions for further study. However, some have questioned the validity of distinguishing NSSI from SA. The objective of this study was to longitudinally examine the correlates, discharge disposition, and rate of re-presentation to emergency services of adults who engaged in NSSI and compare them to (a) adults who engage in SA and (b) adults with no self-harm or suicidal ideation (SI). METHOD: Data came from 4,772 presentations to adult psychiatric services in the emergency departments of tertiary care hospitals in Winnipeg, Canada between January 2009 and June 2012. Chart reviews were conducted for all presentations with NSSI (n = 158), and a sample of those with SA (n = 172) and no SH or SI (n = 173). RESULTS: Among the adults who returned to emergency services, those who originally presented with SA re-presented significantly sooner than those who presented with NSSI. (χ2(1) = 7.457, p = 0.006). Those who originally presented with NSSI that returned to hospital did not return with repeat NSSI, but instead the majority re-presented with suicidal thoughts and SA. Further, those who re-presented with NSSI and SA were less likely to be hospitalized or to receive a referral to mental health services, and more likely to be discharged to usual care at time of initial presentation. CONCLUSIONS: Overall, these findings indicate a trajectory of escalation of self-harm behavior for certain people who engage in NSSI, especially those who re-present to emergency services.HIGHLIGHTSA quarter of people with self-harm re-present to emergency services within four-and-a-half years.Those with suicide attempts re-presented significantly sooner than non-suicidal self-injury.There is a need for increased interventions in emergency services for those with self-harm.

Nonsuicidal Self-Injury and Intimate Partner Violence: Directionality of Violence and Motives for Self-Injury.

Nonsuicidal self-injury (NSSI) is associated with intimate partner violence (IPV) perpetration and victimization. However, extant research has not distinguished between unidirectional and bidirectional IPV and has not examined relationships between IPV and functions of self-injury. This study of 1,018 university students revealed a significantly higher prevalence of NSSI among those who reported bidirectional IPV compared with nonviolent individuals. However, rates of NSSI in the unidirectional IPV groups are more similar to rates of NSSI in the bidirectional group than in nonviolent individuals. Individuals who engaged in bidirectional IPV were more likely to endorse interpersonal functions of self-injury than those who engaged in unidirectional IPV or no IPV. In contrast, intrapersonal functions of NSSI were not associated with IPV. Findings suggest that the association between IPV and NSSI may be best understood in the context of relationship conflict, rather than as a distinct correlate of either IPV victimization or IPV perpetration.

Clarifying the association of eating disorder features to suicide ideation and attempts.

OBJECTIVE: We examine the relationships of eight eating disorder (ED) features to histories of suicide ideation and suicide attempts. METHOD: Participants were 387 adults (62% female, mean age = 36 years) recruited via an online platform, and oversampled for the presence of ED features, who completed standardized self-report measures of study variables. RESULTS: Different ED features predicted suicide ideation versus attempts. Specifically, Restrictive Eating (d = 0.44), Purging (d = 0.30), and Body Dissatisfaction (d = 0.27) were higher among ideators compared to nonsuicidal participants. In contrast, Muscle Building (d = 0.31), Excessive Exercise (d = 0.26), Cognitive Restraint (d = 0.23), and Restrictive Eating (d = 0.20) were higher among attempters compared to ideators-however, we note that the p-values for these effects range between 0.02 and 0.04 and it is unclear if they would replicate. Independent replication is important. CONCLUSION: Findings have implications for the conceptualization of suicide risk in individuals with EDs.

How the helping process unfolds for clients in suicidal crises: Linking helping-style trajectories with outcomes in online crisis chats.

OBJECTIVES: Crisis counselors' active listening and collaborative problem-solving helping styles have been associated with outcomes for clients in suicidal crises. These associations have been based on static conceptualizations of helping (i.e., helping style for the entire session). Our aim was to further understand how the crisis counseling helping process unfolds (i.e., helping trajectory) and helping trajectories' association with clients' outcomes. METHODS: Online crisis chats (N = 269) with suicidal adults were coded for crisis counselors' helping styles (i.e., active listening and collaborative problem-solving) and clients' outcomes (i.e., resolved or unresolved). Each talk-turn was coded for helping style, which were used to examine helping-style trajectories. RESULTS: Growth-curve models indicated that helping styles varied over the course of chats and that helping trajectories were different for resolved and unresolved chats. In resolved chats, helping styles moved from primarily active listening to primarily problem-solving-with a deceleration in the middle of chats. In unresolved chats, helping initially moved from primarily active listening to primarily problem-solving, but this trajectory decelerated in the middle of chats and then turned back toward primarily active listening. CONCLUSION: Our findings demonstrate that how the helping process unfolds is related to clients' outcomes. Implications for practice and research are discussed.

The three-step theory of suicide: Description, evidence, and some useful points of clarification.

There has been considerable uptake of the Three-Step Theory (3ST) of suicide since its publication in 2015. The 3ST is a concise, evidence-based, and actionable theory that explains suicide in terms of four factors: pain, hopelessness, connection, and capability for suicide. The 3ST has not only been cited in hundreds of scientific papers, but incorporated into continuing education programs, gatekeeper training, and self-help resources. In this context, it is useful to clarify the theory's content and review its scientific support. Thus, the present article describes the 3ST, provides an updated evidence review for each of its premises, and offers several points of clarification so that the claims of the 3ST may be better understood, evaluated, and applied. To date, research (including research on correlates, risk factors, motivations, warning signs, and means-safety interventions) supports the 3ST. At the same time, there are aspects of the theory that are challenging to operationalize and that require further testing.

Clarifying the Relationship of Dissociative Experiences to Suicide Ideation and Attempts: A Multimethod Examination in Two Samples.

Fears of pain, injury, and death may represent key barriers to acting on suicidal thoughts. Dissociation, which involves a disconnection from one's body, may reduce fears and sensations of pain associated with harming the body, in turn facilitating suicide attempts. This study examined whether dissociation differentiated individuals with a history of suicide attempts from those with a history of suicide ideation, and investigated whether other relevant constructs explain this relationship. Sample 1 included 754 undergraduates (Mage = 21, 79% female) who completed a battery of self-report measures. Sample 2 included 247 undergraduates (Mage = 19, 74% female) who completed a self-report measure of dissociation, a clinical interview regarding suicide history, and four counterbalanced behavioral pain tolerance tasks. In both samples, dissociation was elevated in lifetime attempters compared to ideators (d = 0.28; d = 0.46; ps = 0.01) and slightly elevated in lifetime ideators compared to nonsuicidal individuals (d = 0.19, p = .02; d = 0.24, p = .47), though this effect was non-significant in the latter sample. In Sample 1, dissociation no longer differentiated attempters from ideators after controlling for clinical covariates. In Sample 2, dissociation was unrelated to behavioral pain tolerance tasks, and these tasks did not account for the association between dissociation and attempts. Overall, dissociation differentiated individuals with a history of suicide attempts from those with ideation alone in both samples. Pain tolerance did not explain this association; instead, it is possible that the relationship of dissociation to suicide attempts is due to "third variables" associated with both phenomena, such as symptoms of borderline personality disorder or posttraumatic stress disorder.

Intrapersonal and Interpersonal Functions as Pathways to Future Self-Harm Repetition and Suicide Attempts.

Background: Research has identified functions of non-suicidal self-harm/self-injury (NSSH) but whether functions change over time, from adolescence to early adulthood, or predict the continuation of the behavior prospectively remains unclear. This study aimed to prospectively explore whether intrapersonal and interpersonal NSSH functions in adolescence predict repetition of self-harm (regardless of suicidal intent) and incident suicide attempts in early adulthood. Methods: Participants were 528 individuals with NSSH at age 16 years from the Avon Longitudinal Study of Parents and Children (ALSPAC), a population-based birth cohort in the UK. Descriptive statistics were used to explore changes in functions over time from age 16 to 21, and logistic regression used to examine associations between NSSH functions and repeat self-harm and suicide attempts at age 21, 24, and 25 years. Findings: The majority of 16-year-olds with NSSH endorsed intrapersonal (e.g., affect regulatory) functions only (73% at 16 years and 64% at 21 years). Just under half of adolescents (42%) and three quarters of 21 years olds reported more than one function simultaneously. A greater number of intrapersonal functions at 16 years independently predicted future repetition of self-harm at ages 21-25 years, over and above interpersonal functions (OR = 1.46, 95% CI 1.06-2.01). Interpersonal functions during adolescence did not predict repeat self-harm or suicide attempts in adulthood. Discussion: Our findings suggest that intrapersonal but not interpersonal NSSH functions are a prospective risk factor for future self-harm and might also predict incident suicide attempts. The results highlight the central role of underlying affective difficulties and motivations in self-harm maintenance.

Examining the Three-Step Theory (3ST) of Suicide in a Prospective Study of Adult Psychiatric Inpatients.

This study examined the validity and predictive utility of the three-step theory (3ST) of suicide in psychiatric patients. Participants were 190 consecutively admitted adult psychiatric inpatients (53% female, 60% White, ages 18-73) assessed at three time points: baseline, 4 weeks later (n = 112), and 3 months postdischarge (n = 102). Results were broadly supportive of the 3ST. First, at baseline, an interactive model of pain and hopelessness accounted for substantial variability in suicidal desire, even when controlling for depression and lifetime ideation. This result replicated in different genders and age ranges (i.e., 18-32 and 33-73). Further, pain and hopelessness were robust predictors of suicidal desire weeks and months into the future. Second, among those with pain and hopelessness, lower connectedness, as well as the extent to which pain exceeds connectedness, were robust predictors of higher suicidal desire. Last, a baseline measure of practical capability for suicide predicted suicide attempts both retrospectively and prospectively, even when controlling for lifetime ideation-however, dispositional and acquired contributors to capability were less predictive. Results support the validity and predictive utility of the 3ST, and suggest that the theory may have utility for guiding risk assessment and intervention.

Examining suicidal desire through the lens of the three-step theory: A cross-sectional and longitudinal investigation in a community sample.

OBJECTIVE: Advancing evidence-based theories of suicide is critical to improving suicide prevention. The aim of the current study was to investigate suicidal desire through an emerging theory of suicide, the Three-Step Theory (3ST). Specifically, this study investigated the validity and predictive utility of Steps 1 and 2 of the 3ST in a Canadian community sample. METHOD: Participants were 487 adults between the ages of 35 to 90 (M = 59; 64% female, 87% White) who completed self-report measures assessing suicidal ideation and attempt history, hopelessness, psychological pain, and 5 forms of social connectedness at baseline and 6 months later. RESULTS: In support of 3ST predictions, cross-sectional analyses showed (a) the combination of pain and hopelessness strongly correlated with suicidal desire, and (b) connectedness was protective of suicidal desire among those high in pain and hopelessness. Regarding predictive utility, longitudinal analyses showed that pain and hopelessness were strong predictors of future suicidal desire and that connectedness was protective against future suicidal desire. These relationships of pain, hopelessness, and connectedness remained when controlling for baseline suicidal desire. CONCLUSIONS: Results support the validity and predictive utility of 3ST hypotheses related to suicidal desire. Taken together with previous studies, findings suggest that Steps 1 and 2 are useful for conceptualizing suicide risk and prevention. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

A Co-Twin Control Study of the Association Between Bullying Victimization and Self-Harm and Suicide Attempt in Adolescence.

PURPOSE: The aim of the study was to investigate the magnitude of an independent association between bullying victimization and self-harm and suicide attempt in adolescence after adjusting for unmeasured and measured confounding factors. METHODS: Using the Child and Adolescent Twin Study in Sweden, we examined twins born between 1994 and 1999 (n = 13,852). Twins self-reported bullying victimization at age 15 years and self-harm and suicide attempt at age 18 years. We created a factor score of 13 bullying items, on which self-harm and suicide attempt items were regressed in three models: (1) among unrelated individuals; (2) among co-twins, in which a twin exposed to more bullying was compared with his/her co-twin who was exposed to less; and (3) among co-twins while adjusting for indicators of childhood psychopathology. RESULTS: Among unrelated individuals, a one standard deviation increase in bullying victimization was associated with increased odds for self-harm (odds ratio [OR], 1.29 [95% confidence interval, 1.23-1.36]) and suicide attempt (OR, 1.68 [1.53-1.85]). Among co-twins, the odds attenuated for self-harm (OR, 1.19 [1.09-1.30]) and suicide attempt (OR, 1.39 [1.17-1.66]). Finally, when accounting for childhood psychopathology, there was a 14% (1.04-1.25) and 25% (1.03-1.52) relative increase in odds of self-harm and suicide attempt, respectively. CONCLUSIONS: The results suggest that bullying victimization was uniquely associated with self-harm and suicide attempt over and above the confounding because of unmeasured and measured factors (i.e., familial vulnerability and pre-existing psychopathy). However, magnitudes were small, suggesting that additional interventions and screenings are needed to address suicidality apart from bullying interventions.

Sexual orientation and adolescent suicide attempt and self-harm: a co-twin control study.

BACKGROUND: Research has demonstrated that individuals who identify as a sexual minority (e.g., gay/lesbian, bisexual) are at increased risk for suicidality-related outcomes. However, previous research is primarily limited by the lack of adjustment for unmeasured (i.e., genetic and environmental) confounding factors and previous psychopathology. METHODS: Using the Child and Adolescent Twin Study in Sweden, we employed a co-twin control design to examine the extent to which the association between sexual orientation and adolescent suicide attempt and self-harm (SA/SH) was independent of genetic and environmental factors shared by twins, as well as measured symptoms of childhood psychopathology. RESULTS: Adolescents who identified as a sexual minority (i.e., gay/lesbian, bisexual, or other sexual orientation) were at two-fold increased odds for SA/SH (OR, 2.01 [95% confidence interval, 1.63-2.49) compared to heterosexual adolescents. When adjusting for all genetic and shared environmental factors that make twins similar and for measured childhood psychopathology, the association remained positive but attenuated to OR, 1.55 (1.11-2.16). CONCLUSIONS: Identifying as a sexual minority was associated with approximately 50% increased odds of SA/SH in adolescence after adjusting for unmeasured genetic and environmental factors shared by twins and for childhood psychopathology. The results support that environmental factors specifically associated with identifying as a sexual minority likely increase risk for SA/SH. Our findings highlight the need to monitor suicidality risk among this group.

Treatments for Self-Injurious Thoughts and Behaviors in Youth: Progress and Challenges.

Self-injurious thoughts and behaviors (SITBs) remain a common clinical problem in youth. This article reviews the state of knowledge regarding psychosocial treatments for SITBs in youth. Broadly speaking, psychosocial treatments that incorporate parents/family and that emphasize skills development (including emotion regulation and interpersonal skills) appear to produce the best outcomes. We also describe several challenges to the implementation of evidence-based psychotherapy, as well as potential solutions to these challenges, and provide an illustrative case example. Finally, because even evidence-based psychosocial treatments can take weeks to produce effects, increased attention has been given to biological approaches such as esketamine administration and transcranial direct current stimulation that have potential to yield rapid improvement for acute suicidal ideation, though evidence for the safety and efficacy of these approaches is in the early stages.
