Routinized Assessment of Suicide Risk in Clinical Practice: An Empirically Informed Update

From identity-based distress to thinking "I am better off being dead:" Minority stress, posttraumatic cognitions, and suicidal ideation

BACKGROUND

Suicidal ideation (SI) disproportionately impacts individuals with minoritized race/ethnicity, gender, and sexual orientation. Minority stress - i.e., traumatic, insidious distress that results from acts of discrimination - may lead to the formation of posttraumatic cognitions that may generalize to suicidal ideation, elevating SI risk in minoritized populations. The current study aimed to test this potential relationship by examining whether minority stress and posttraumatic cognitions accounted for the association between discrimination and SI.

METHODS

Series of structural equation models, including multigroup confirmatory factor analyses conducted to test invariance of latent constructs, were estimated on cross-sectional data collected from minoritized young adults (n = 337).

RESULTS

Results supported the hypothesized model: experience of discrimination indirectly associated with SI via correlations shared between minority stress and posttraumatic cognitions. Experiences of discrimination lacked a significant correlation with SI while accounting for minority stress and posttraumatic cognition variance. Invariance testing conducted to account for applicability of the model across race, ethnicity, sexual orientation, and plurality of minoritized identities all demonstrated that the model was applicable across these identity dimensions.

LIMITATIONS

Granular inspection of identity dimensions was infeasible due to sample size and causal inferences cannot be drawn given cross-sectional nature of the data used.

CONCLUSIONS

Posttraumatic cognitions within the context of discrimination may be effective treatment targets for minoritized individuals who present with minority stress and SI. Future studies should aim to replicate such findings longitudinally to infer temporality.

Beyond words: Semantic satiation and the mental accessibility of the concept of suicide

Disrupting the accessibility of the mental representation of suicide may be a possible pathway to a strategy for suicide prevention. Our study aims to theoretically evaluate this perspective by examining the impact of temporarily disrupting the concept of suicide on perceptions of suicide. Using a within-subject design, we tested the effects of semantic satiation targeting the word "suicide" on the perceptual judgment of suicide-relevant pictures in 104 young adults. On each trial, participants repeated aloud one of the three words (i.e., "accident," "murder," or "suicide") either three times (priming) or 30 times (satiation) and indicated whether a subsequent picture matched with the word. Results indicated that satiation of the word "suicide" slowed the accurate categorization of pictures related to all three words, and satiation of "murder" and "accident" delayed participants' judgment of suicide-relevant pictures. Our findings support that semantic satiation can render the suicide concept temporarily less accessible, thereby providing preliminary support for the strategy of concept disruption in suicide prevention.

Machine learning approach for the development of a crucial tool in suicide prevention: The Suicide Crisis Inventory-2 (SCI-2) Short Form

The Suicide Crisis Syndrome (SCS) describes a suicidal mental state marked by entrapment, affective disturbance, loss of cognitive control, hyperarousal, and social withdrawal that has predictive capacity for near-term suicidal behavior. The Suicide Crisis Inventory-2 (SCI-2), a reliable clinical tool that assesses SCS, lacks a short form for use in clinical settings which we sought to address with statistical analysis. To address this need, a community sample of 10,357 participants responded to an anonymous survey after which predictive performance for suicidal ideation (SI) and SI with preparatory behavior (SI-P) was measured using logistic regression, random forest, and gradient boosting algorithms. Four-fold cross-validation was used to split the dataset in 1,000 iterations. We compared rankings to the SCI-Short Form to inform the short form of the SCI-2. Logistic regression performed best in every analysis. The SI results were used to build the SCI-2-Short Form (SCI-2-SF) utilizing the two top ranking items from each SCS criterion. SHAP analysis of the SCI-2 resulted in meaningful rankings of its items. The SCI-2-SF, derived from these rankings, will be tested for predictive validity and utility in future studies.

Obsessive-compulsive symptoms, perceived burdensomeness, and thwarted belongingness: Associations and implications among US veterans

OBJECTIVE

Obsessive-compulsive disorder (OCD) is among the most debilitating psychiatric disorders worldwide, but has gone relatively unnoticed within the US veteran population. Simultaneously, suicide rates continue to remain high within this population despite the high volume of veterans who receive psychiatric care. With recent research demonstrating OCD's unique relationship with suicidality, it is imperative to explore this association and factors that may explain this association within veterans.

METHODS

The present study investigated OCD symptoms and their relationship with two known risk factors of suicide, perceived burdensomeness (PB) and thwarted belongingness (TB), in two samples of veterans.

RESULTS

In the first study (N = 100), OCD symptoms were found to be uniquely related to both PB and TB even after covarying for demographics, trauma exposure, and probable depression. In the second study (N = 99), these relationships were replicated longitudinally. OCD symptoms at baseline were found to be indirectly related to suicidal ideation severity at a 1-month follow-up via PB and TB at post-treatment.

CONCLUSION

This study highlights the importance of assessing and addressing OCD symptoms within veterans due to the unique relationship these symptoms have with suicidal constructs. A deeper understanding of the impact of OCD within the veteran population will inform future prevention and intervention efforts.

Rapid screening for suicide risk: An algorithmic approach

INTRODUCTION

In the United States, primary medical care settings are the first accessed resource for both medical and behavioral health care. Thus, there is a clear need for accurate and efficient behavioral health screening in this setting, including routine surveillance screening for suicide risk. The Multidimensional Behavioral Health Screen (MBHS), a broadband but very brief screening tool developed specifically for primary care, has been updated to include an algorithm that classifies suicide risk based on the interpersonal-psychological theory of suicide, and associated interview and decision framework. This study aims to evaluate the predictive accuracy of the new MBHS 2.0 suicide risk algorithm, with actual risk determined by clinical suicide risk interview.

METHOD

Data were collected as part of a larger study that, overall, included 551 college student participants. Of these, 309 completed the MBHS 2.0 and the clinical suicide risk interview, the two measures reported here. The final participant count was 299 following the removal of incomplete or invalid cases. Predicted suicide risk as determined by the MBHS 2.0 (Low, Mild, At least Moderate) was compared to actual risk as determined by clinical interview (Low, Moderate, Severe, Extreme).

RESULTS

Utilizing chi-square analyses, data show a significant association between the predicted suicide risk category based on the MBHS 2.0 algorithm and the actual risk category based on the semi-structured clinical interview. Furthermore, classification analyses suggest that primary care providers will be able to confidently assess the suicide risk level for the majority of their patients when using the MBHS.

CONCLUSION

Findings suggest that the MBHS 2.0 can be an accurate and efficient tool for use by primary care providers in classifying suicide risk. Future research will be useful to evaluate the utility of the suicide risk algorithm among primary care populations.

Negative Urgency, (Lack of) Premeditation, and Sensation Seeking: Indirect Relationships with Suicidal Ideation through Thwarted Interpersonal Needs

OBJECTIVE

Differences in how impulsivity is conceptualized, along with a myopic focus on impulsivity's relationship with historical suicidal behaviors, have resulted in limited implications made from prior research regarding impulsivity and suicidal thoughts and behaviors. The current study investigated the indirect effect facets of impulsivity may have on suicidal ideation, specifically, through thwarted interpersonal needs.

METHODS

Participants were N = 424 undergraduate students who completed a cross-sectional survey. Participants completed the Urgency, Premeditation, Perseverance, Sensation Seeking, Impulsive Behavior Scale (UPPS), the Adult Suicide Ideation Questionnaire (ASIQ), and the Interpersonal Needs Questionnaire (INQ). Parallel mediation models were run to examine the relation between facets of impulsivity, perceived burdensomeness, thwarted belongingness, and suicidal ideation.

RESULTS

Thwarted belonginess and perceived burdensomeness significantly accounted for the variance in the relation between negative urgency and suicidal ideation. Neither thwarted belongingness nor perceived burdensomeness significantly explained variance in the relation between (lack of) premeditation and suicidal ideation. Conversely, perceived burdensomeness and thwarted belonginess significantly explained the inverse relation between sensation seeking and suicidal ideation (i.e., greater sensation seeking was related to lower perceived burdensomeness and thwarted belongingness and in turn lower suicidal ideation).

CONCLUSION

Negative urgency, in particular, is related to suicidal ideation through thwarted interpersonal needs. Future research should continue to differentiate between various types of impulsivity and its relationship with both suicidal ideation and behaviors utilizing both cross-sectional and ambulatory assessments of these constructs.HIGHLIGHTSNegative urgency is related to suicidal ideation.Negative urgency is related to thwarted interpersonal needs.Thwarted interpersonal needs partially explain the relation between negative urgency and suicidal ideation.

Specificity, frequency, and intent: Multiple characteristics of adolescents' suicide plan correlate with their history of suicidal behavior

BACKGROUND

Suicide plans (SP) can be a common precipitant to suicidal behavior (SB) during adolescence, and SPs can vary in how specific they are, how frequently they are thought about, and how strongly they are intended to be enacted. To date, we have limited understanding of how discrete SP characteristics (i.e., specificity, frequency, and intent to act) present among adolescents, and whether they relate to SB. In the current study, we investigated SP characteristics and their association with SB history among adolescents who had previously considered suicide.

METHODS

Participants were 142 community-based adolescents (14-19 years; M = 17.6, SD = 1.4) who reported a history of suicidal ideation. Adolescents provided responses pertaining to their SP history, SP characteristics, and SB history, via the Self-Injurious Thoughts and Behaviors Interview-Revised (SITBI-R).

RESULTS

Greater specificity, frequency, and intent were each associated with modestly increased odds of reporting an SB history. The associations between plan specificity and SB history, as well as between frequency of thinking about one's SP and SB history, were mediated by adolescents' intent to act on their SP.

CONCLUSIONS

It may not only be whether, but how, adolescents plan for suicide that relates to their tendency to engage in SB.

Examining Blunted Initial Response to Reward and Recent Suicidal Ideation in Children and Adolescents Using Event-Related Potentials: Failure to Conceptually Replicate Across Two Independent Samples

A recent study by Tsypes and colleagues (2019) found that children with recent suicidal ideation had blunted neural reward processing, as measured by the reward positivity (RewP), compared to matched controls, and that this difference was driven by reduced neural responses to monetary loss, rather than to reward. Here, we aimed to conceptually replicate and extend these findings in two samples (n = 264, 27 with suicidal ideation; and n = 314, 49 with suicidal ideation at baseline) of children and adolescents (11 to 15 years and 8 to 15 years, respectively). Results from both samples showed no evidence that children and adolescents with suicidal ideation have abnormal reward or loss processing, nor that reward processing predicts suicidal ideation two years later. The results highlight the need for greater statistical power, as well as continued research examining the neural underpinnings of suicidal thoughts and behaviors.

Impulsivity traits and suicide related outcomes: A systematic review and meta-analysis using the UPPS model

BACKGROUND

The affective, cognitive, and behavioral aspects of impulsivity involved in suicide-related outcomes can be investigated through the UPPS model, which conceptualizes these facets in multidimensional terms related to negative and positive urgency, lack of premeditation and perseverance, and sensation seeking. This systematic review and meta-analysis provided a comprehensive understanding of the role of all facets of impulsivity in the development of suicidal ideation and behaviors.

METHODS

We conducted a systematic search on six databases (PsycINFO, PsycARTICLES, PubMed, MEDLINE, Scopus, and Web of Science) until May 5,2023. Overall, 49 studies met the criteria for systematic review, of which 37 were included in a meta-analysis of data from 17.898 individuals. Additional moderation analyses included age, gender, sample status, country of study conduct, assessment instruments, type of suicide-related outcome, study quality, and research design.

RESULTS

We found significant relationships between aspects of impulsivity and suicide-related outcomes. Specially, affective facets related to impulsivity showed a stronger association with suicidal ideations and attempts than cognitive and behavioral dimensions, recommending the main involvement of emotional aspects-positive and negative-in suicide-related dimensions.

LIMITATIONS

The limited number of studies may have negatively impacted the power of moderation analyses. In addition, for most dimensions of impulsivity, the limited number of longitudinal studies did not allow to test the moderating role of research design.

CONCLUSIONS

This study supports the role of impulsivity in suicidal ideation and behavior, identifying the affective component of impulsivity as the most involved, providing a significant contribution from a clinical and diagnostic point of view.

Self-burdensomeness, other-burdensomeness, and suicidal ideation

Perceiving oneself as a burden to others (other-burdensomeness), as well as perceiving one's selfhood as a burden (self-burdensomeness), have been proposed as risk factors for suicidal ideation. Yet, it is unclear whether the altruistic motive of being a burden to others or the self-oriented motive of being a burden on oneself is more relevant to suicidal ideation. Given this background, two rival mediation models were tested. Data from N = 228 outpatients (64% female; age: M(SD) = 38.69 (12.27), range:17-65) undergoing psychotherapy were collected at two measurement time points over a three-month period (first measurement = T1, second measurement = T2). The significant positive association between other-burdensomeness (T1) and suicidal ideation (T2) was partially mediated by self-burdensomeness (T1). Furthermore, the significant positive association between self-burdensomeness (T1) and suicidal ideation (T2) was partially mediated by other-burdensomeness (T1). Results suggest that suicidal ideation can develop from both an altruistic, self-sacrificial perception of being a burden to others, as well as from a more self-oriented perception of being a burden to oneself. There is no indication that either self-burdensomeness or other-burdensomeness is a stronger indicator in the development of suicidal ideation.

Psychometric Properties of the Self-Injurious Thoughts and Behaviors Interview-Short Form Among U.S. Active Duty Military Service Members and Veterans

We assessed the interrater reliability, convergent validity, and discriminant validity of the Self-Injurious Thoughts and Behaviors Interview-Short Form (SITBI-SF) in a sample of 1,944 active duty service members and veterans seeking services for posttraumatic stress disorder (PTSD) and related conditions. The SITBI-SF demonstrated high interrater reliability and good convergent and discriminant validity. The measurement properties of the SITBI-SF were comparable across service members and veterans. Approximately 8% of participants who denied a history of suicidal ideation on the SITBI-SF reported suicidal ideation on a separate self-report questionnaire (i.e., discordant responders). Discordant responders reported significantly higher levels of PTSD symptoms than those who denied suicidal ideation on both response formats. Findings suggest that the SITBI-SF is a reliable and valid interview-based measure of suicide-related thoughts and behaviors for use with military service members and veterans. Suicide risk assessment might be optimized if the SITBI-SF interview is combined with a self-report measure of related constructs.

A pilot study of sleep scholar: A single-session, internet-based insomnia intervention for college students with a history of suicide ideation

OBJECTIVE

Establish the feasibility and acceptability of Sleep Scholar, a single-session, self-guided, internet-based insomnia intervention.

PARTICIPANTS

College students with a lifetime history of suicide ideation and at least subclinical insomnia symptoms.

METHODS

Participants (N = 38) completed pretreatment sleep diaries, Sleep Scholar, and post-treatment feasibility, acceptability, and clinical measures.

RESULTS

Approximately 33 students could be recruited per semester, the overall attrition rate was 47%, Sleep Scholar was completed in approximately 30 minutes, and the majority of treatment information was retained. Participants reported positive acceptability and satisfaction, and approximately half of participants adhered to their prescribed time in bed recommendations. Most clinical measures had adequate variability and internal consistency, and post-hoc analyses revealed clinically significant reductions in several mental health symptoms.

CONCLUSIONS

Sleep Scholar is feasible in college settings, acceptable for college students, and produced reductions in mental health symptoms during an uncontrolled trial. Implications for a randomized-controlled trial are discussed.

Validation of the Arabic version of the brief irritability test (Ar-BITe) in non-clinical adolescents

BACKGROUND

Despite the substantial clinical relevance of irritability in the development and maintenance of several mental disorders and its negative effects on functioning, no valid and reliable measures are available yet to identify the presence and consequences of irritability as a distinct construct among the Arabic-speaking populations. To bridge this gap, and help advance this field in the under-researched Arab region, we aimed to validate an Arabic-language version of the Brief Irritability Test (BITe).

METHODS

Eligible participants were native Arabic-speaking non-clinical adolescents from Lebanon; 527 participants aged 15.73 ± 1.81 years (56% females) completed the survey.

RESULTS

Utilizing the Confirmatory Factor Analysis approach, we found that the five items of the Arabic BITe loaded into a single factor structure. The scale showed excellent reliability, as both Cronbach's alpha and McDonald's omega coefficient values were of 0.88. Multi-group analyses showed invariance across sex groups in our sample at the configural, metric, and scalar levels. Female adolescents exhibited higher BITe scores than their male counterparts (14.01 vs. 13.25), but this difference did not reach the statistical significance. Good concurrent validity was supported based on positive correlations between irritability scores and measures of aggression, anger and hostility (r Pearson's coefficients ranging from 0.35 to 0.42), as well as positive correlations with insomnia symptoms scores.

CONCLUSION

The present findings allow us to conclude that the Arabic version of the BITe is a unidimensional, reliable, valid, brief, and economic self-report measure of the irritability construct for both male and female Arabic-speakers. Providing an Arabic validated version of the BITe will hopefully foster the research efforts of the Arab scientific community in this area, and promote the implementation of timely, evidence-informed and culturally-sensitive mental health interventions that appropriately address irritability-related problems and consequences among Arab young populations.

Validation of the Farsi version of the Suicide Ideation and Behavior Scale

Objective

Suicide ideation and suicide attempts are prevalent in Farsi speaking populations. The present study aimed at validating the Farsi version of the Suicide Ideation and Behavior Scale (SIBS).

Methods

Reliability and validity of the Farsi version of the SIBS were established in a highly burdened Afghan student sample (N = 279). Internal consistency, convergent and discriminant validity were investigated, and confirmatory factor analysis was conducted.

Results

The Farsi version of the SIBS was shown to have a unidimensional structure with excellent internal consistency, as well as good convergent and divergent validity.

Discussion

The results suggest that the SIBS is a brief, reliable, and valid measure of current suicidal ideation and behavior that can be used in Farsi speaking populations.

Appearance-related safety behaviors predict symptoms of body dysmorphic disorder following internet-based treatment

Recent experimental evidence has found that appearance related safety behaviors (i.e., practices meant to avoid a perceived feared outcome) likely play a crucial role in maintaining symptoms of body dysmorphic disorder (BDD). The present study sought to determine if these behaviors predicted BDD symptom severity following treatment. Participants (N = 50) with BDD were randomized to either eight sessions of interpretation bias modification or progressive muscle relaxation. Both treatments led to reductions in BDD symptom severity and appearance-related safety behaviors, though moderate levels of safety behaviors persisted at both posttreatment and follow-up. Importantly, post-treatment appearance related safety behaviors significantly predicted BDD symptom severity at three-month follow-up. Taken together, the present findings suggest appearance related safety behaviors maintain BDD symptoms following effective computerized treatments and provide further evidence for their importance in the treatment of BDD.

Examining sleep disturbance components as near-term predictors of suicide ideation in daily life

Suicide ideation emerges and fluctuates over short timeframes (minutes, hours, days); however, near-term predictors of such fluctuations have not been well-elucidated. Sleep disturbance is a distal suicide risk factor, but less work has examined whether daily sleep disturbance predicts near-term changes in suicide ideation. We examined subjective sleep disturbance components as predictors of passive and active suicide ideation at the within-person (i.e., day-to-day changes within individuals relative to their own mean) and between-persons (individual differences relative to the sample mean) levels. A transdiagnostic sample of 102 at-risk young adults ages 18-35 completed a 21-day ecological momentary assessment protocol, during which they reported on sleep and passive and active suicide ideation. At the within-persons level, nightmares, sleep quality, and wake after sleep onset predicted passive suicide ideation, and sleep quality and wake after sleep onset predicted active suicide ideation. At the between-persons level, nightmares, sleep onset latency, and sleep quality were associated with passive suicide ideation, and sleep onset latency was associated with active suicide ideation. In contrast, suicide ideation did not predict subsequent sleep at the within-person level. Specific sleep disturbance components are near-term predictors of intraindividual increases in suicide ideation and may hold promise for suicide prevention and intervention.

The impact of social connection on near-term suicidal ideation

While predominant suicide theories emphasize the role of social connectedness in suicidal thinking, there is a need to better understand (a) how specific aspects of social connection relate to suicidal ideation and (b) the timeframe over which these relationships persist. The current study examined ecological momentary assessment data over a 30-day period from 35 participants with past-year suicidal thoughts or behaviors (mean age = 25.88; 62.9% women; 68.6% White) to address these questions. Results demonstrated that absence of social contact was associated with next timepoint suicidal ideation, even after considering the suicidal ideation autoregressive effect (i.e., concurrent), with effects strongest in the short-term. Findings provide preliminary evidence of the need to assess for the presence of social contact, and for assessments to occur in close proximity (i.e., a few hours), to capture the true dynamics of risk for suicidal ideation. Although needing replication, results suggest importance of just-in-time interventions targeting suicidal ideation.

Perceived Burdensomeness and Thwarted Belongingness in Text Messages of Suicide Attempt Survivors

OBJECTIVE

Perceived burdensomeness and thwarted belongingness are considered interpersonal risk factors for suicide. Examining these themes in personal text messages may help identify proximal suicide risk.

METHOD

Twenty-six suicide attempt survivors provided personal text messages and reported dates for past periods characterized by positive mood, depressed mood, suicidal ideation (with no attempt), or the two-week period leading up to suicide attempt(s). Texts were then classified into the applicable period based on matching dates. Texts (N = 194,083; including n = 86,705 outgoing texts) were coded for perceived burdensomeness and thwarted belongingness by masked trained raters. Multilevel models were fit to examine whether the target themes (combined into one overall interpersonal risk variable due to low base rate) were more prevalent in texts sent during higher risk episodes (e.g., suicide attempt vs. depressed mood episodes).

RESULTS

0.57% of outgoing texts contained either target theme. As hypothesized, logistic models showed participants were more likely to send texts containing the target themes during suicide attempt episodes relative to suicidal ideation (with no attempt) episodes, depressed mood episodes, and positive mood episodes, and during suicidal ideation (with no attempt) episodes relative to positive mood episodes. All contrasts were robust to post-hoc correction except for suicide attempt episodes vs. ideation (with no attempt) episodes. No other significant pairwise differences for episode type emerged.

CONCLUSIONS

Despite the small sample size and low base rate of target themes in the texts, perceived burdensomeness and thwarted belongingness were associated with intra-individual suicide risk severity in personal text messages.

Mediators of the Relationship Between Adverse Childhood Experiences (ACEs) and Symptoms of Anxiety, Depression, and Suicidality among Adults

Adverse childhood experiences (ACEs) are consistently found to be negatively associated with physical, psychological, and psychosocial well-being throughout the lifespan. While previous research has established risk factors and noxious outcomes arising post-ACEs, less attention has been given to factors such as resilience, perceived social support, and subjective well-being that may help explain the relationship between ACEs and psychopathology. Hence, the objectives of this study are to examine: (1) the relationships among ACEs and symptoms of anxiety, depression, and suicidality in adulthood, and (2) whether resilience, social support, and subjective well-being mediate the relationship between ACEs and psychopathological symptoms. Cross-sectional data on ACEs, psychological factors, potential mediating variables, and sociodemographic factors were collected from a community sample of adults aged 18-81 (N = 296) via an on-line survey. Endorsing ACEs was significantly and positively correlated with symptoms of anxiety, depression, and suicidality. Results of parallel mediation analyses showed that social support, negative affect, and life satisfaction statistically mediated the relationships between ACEs and psychopathological outcomes in adulthood. These results highlight the importance of identifying potential mediators of the ACEs-psychopathological symptoms relationship to aid in the development of screening and intervention practices that could bolster developmental outcomes following traumatic childhood experiences.

Predictive value of suicidal risk assessment using data from China's largest suicide prevention hotline

BACKGROUND

Suicide hotlines are widely used, with potential for identification of callers at especially high risk.

METHODS

This prospective study was conducted at the largest psychological support hotline in China. From 2015 to 2017, all distressed callers were consecutively included and assessed, using a standardized scale consisting of 12 elements, yielding scores of high risk (8-16), moderate risk (4-7), and low risk (0-3) for suicidal act. All high-risk and half of moderate- and low-risk callers were scheduled for a 12-month follow-up. Main outcomes were suicidal acts (nonlethal attempt, death) over follow-up.

RESULTS

Of 21,346 fully assessed callers, 5822, 11,791, and 3733 were classified as high-, moderate-, or low-risk for suicidal acts, with 8869 callers (4076 high-, 3258 moderate-, and 1535 low-risk) followed up over 12 months. Over follow-up, 802 (9.0 %) callers attempted suicide or died by suicide. The high-risk callers (15.1 %) had 3-fold higher risk for subsequent suicidal acts than moderate- (5.1 %) and 12-fold higher risk than low-risk callers (1.3 %). The weighted sensitivity, specificity, and positive predictive value of high risk scores were 56.4 %, 74.9 %, and 14.4 %.

LIMITATIONS

Assessed callers with different risk levels were followed disproportionally.

CONCLUSIONS

Suicidal risk assessment during a hotline call is both feasible and predictive of risk, guiding resource allocation to higher risk callers.

Cross-national presence and sociodemographic correlates of the suicide crisis syndrome

BACKGROUND

The Suicide Crisis Syndrome (SCS) has been proposed as an acute, pre-suicidal mental state that precedes imminent suicidal behavior; however, its cross-national applicability and sociodemographic correlates have not yet been determined. The present study assessed the presence and severity of the SCS in ten countries and examined several potential sociodemographic correlates (i.e., age, gender, marital status, race/ethnicity) of the SCS.

METHODS

5528 community-based adults across 10 participating countries provided information on their SCS symptoms and sociodemographic characteristics in an anonymous online survey obtained via convenience sampling during the first year of the COVID-19 pandemic.

RESULTS

The SCS occurred cross-nationally, with rates ranging from 3.6% (Israel) to 16.2% (Poland). Those in the United States, South Korea, Poland, and Turkey had the highest severity of symptoms. Participants who were older, identified as cisgender men, and married tended to have lower rates of the SCS than their respective counterparts. There were minimal differences in the SCS by race/ethnicity.

LIMITATIONS

These data were both cross-sectional and collected via convenience sampling, limiting generalizability of findings and information about the SCS's predictive utility.

CONCLUSIONS

These findings support the cross-national presence of the SCS during the COVID-19 pandemic. Sociodemographic correlates aligned with those of suicidal behavior more generally, providing additional evidence for the concurrent/predictive validity of the SCS.

Evaluating the long-term (Three Year) durability of brief interventions targeting risk factors for psychopathology

Despite their brevity, prior work indicates that computer-based interventions can substantially impact risk factors for psychopathology including anxiety sensitivity (AS), thwarted belongingness (TB), and perceived burdensomeness (PB). However, very few studies have assessed the long-term (> 1 year) effects of these interventions. The primary aim of the current study was to evaluate post-hoc, the long-term (3 year) durability of brief interventions targeting risk factors for anxiety and mood psychopathology using data from a pre-registered randomized clinical trial. Moreover, we were interested in evaluating whether mitigation in these risk factors mediated long-term symptom change. A sample determined to be at-risk for anxiety and mood pathology based on elevations on several risk factors (N = 303) was randomly assigned to one of four experimental conditions focused on: (1) reducing TB and PB; (2) reducing AS, (3) reducing TB,PB, and AS; or (4) a repeated contact control condition. Participants were assessed at post-intervention, one, three, six, 12, and 36 month follow-ups. Participants in the active treatment conditions showed sustained reductions in AS and PB through long-term follow-up. Mediation analyses suggested that reductions in AS mediated long-term reductions in anxiety and depression symptoms. These findings suggest that brief and scalable risk reduction protocols have long-term durability and efficacy both in terms of reducing risk factors for psychopathology.

Is physical pain causally related to suicidal behavior: An experimental test

Existing evidence suggests a link between physical pain and suicide, but the nature of this relationship remains unknown. To address this critical gap in knowledge, the present study leveraged a validated virtual reality (VR) suicide paradigm to experimentally examine the causal effects of physical pain on subsequent virtual suicidal behaviors. Based on previous findings, we hypothesized that physical pain would causally drive virtual suicidal behavior only if suicide was conceptualized as having desirable anticipated consequences (e.g., a means of escaping from current pain; an opportunity to avoid future pain). We tested this by randomizing 326 participants across four different conditions: a physical pain condition, an anticipated escape condition, an anticipated avoidance condition, and a control condition. As predicted, physical pain alone did not result in statistically significant increases in VR suicide rates; however, the anticipation that virtual suicidal behavior would result in the avoidance of future physical pain had a large causal effect on VR suicide rates (B = 1.61, p < .001, IRR = 5.01). We failed to find evidence that anticipating that VR suicide would provide an escape from currently experienced physical pain increases the likelihood of VR suicide. Our findings add to a growing body of evidence suggesting that the anticipated consequences of suicide (e.g., avoidance of future physical pain) may serve as primary causes of suicidal behavior.

Temporal dynamics of interoceptive attention and positive and negative affect in adults engaging in disordered eating and nonsuicidal self-injury

OBJECTIVE

Interoception (the sense of the body's state) is associated with eating disorders and nonsuicidal self-injury, potentially through relationships with affect. We examined the relationship between interoceptive attention and both positive and negative affect.

METHODS

Participants (N = 128) who reported recent self-harm (i.e., disordered eating and/or non-suicidal self-injury) completed ecological momentary assessment for 16 days. Participants completed multiple daily assessments of affect and interoceptive attention. We then tested the temporal dynamic relationship between interoceptive attention and affect.

RESULTS

There was a relationship between positive affect and interoceptive attention such that people with higher average positive affect, and times when people were above their typical positive affect, were associated with higher interoceptive attention. There was a negative relationship between negative affect and interoceptive attention, such that people with higher average negative affect, and times when people were above their own typical negative affect, were associated with lower interoceptive attention.

CONCLUSIONS

Better mood may associate with greater willingness to attend to body sensations. Our findings support active inference models of interoception and highlight the importance of refining our understanding of the dynamic nature of interoception and its relationship with affect.

Therapeutic alliance and change in suicide ideation among psychiatric inpatients at risk for suicide

BACKGROUND

Therapeutic alliance is thought to be essential in the treatment of suicidality. Surprisingly, studies about the association between therapeutic alliance and change in suicide ideation over the course of treatment are sparse and reported inconsistent results. Furthermore, theoretically important moderators were rarely explored empirically.

METHODS

We investigated the association between therapeutic alliance and change in suicide ideation (difference between intake and discharge), unadjusted and adjusted for potential confounding variables (diagnoses, sociodemographics etc.) in a sample of 351 inpatients treated in a psychiatric department specialized in crisis intervention and suicide prevention. We also explored if the association was moderated by suicide ideation at intake, history of suicide attempts, and borderline personality disorder (BPD). We ran sensitivity analyses for different diagnostic subgroups, history of suicide attempts, and a quantitative measure of BPD symptoms.

RESULTS

We found a moderate association between therapeutic alliance and change in suicide ideation (r = 0.30, p < 0.01). This association remained robust after accounting for potentially confounding variables. Suicide ideation at intake, history of suicide attempts, and BPD were not statistically significant moderators. Sensitivity analyses led to similar results.

LIMITATIONS

Therapeutic alliance was assessed only at the end of treatment and causality cannot be inferred from our study method.

CONCLUSIONS

Therapeutic alliance was a robust correlate of improvement in suicide ideation among psychiatric inpatients at risk for suicide, independent from diagnostic groups and other patient characteristics. Our results support the crucial role of therapeutic alliance in the treatment of patients at risk for suicide.

Factor Structure and Validation of the Revised Suicide Crisis Inventory in a Korean Population

OBJECTIVE

Because of the exceptionally high suicide rates in South Korea, new assessment methods are needed to improve suicide prevention. The current study aims to validate the revised Suicide Crisis Inventory-2 (SCI-2), a self-report measure that assesses a cognitiveaffective pre-suicidal state in a Korean sample.

METHODS

With data from 1,061 community adults in South Korea, confirmatory factor analyses were first conducted to test the proposed one-factor and five-factor structures of the SCI-2. Also, an exploratory factor analysis (EFA) was performed to examine possible alternative factor structure of the inventory.

RESULTS

The one-factor model of the SCI-2 resulted in good model fit and similarly, the five-factor model also exhibited strong fit. Comparing the two models, the five-factor was evaluated as the superior model fit. An alternative 4-factor model derived from EFA exhibited a comparable model fit. The Korean version of the SCI-2 had high internal consistency and strong concurrent validity in relation to symptoms of suicidal ideation, depression, and anxiety.

CONCLUSION

The SCI-2 is an appropriate and a valid tool for measuring one's proximity to imminent suicide risk. However, the exact factor structure of the SCI-2 may be culture-sensitive and warrants further study.

Differences in suicide risk correlates and history of suicide ideation and attempts as a function of disability type

BACKGROUND

Disability status is associated with correlates of suicide risk (perceived burdensomeness, thwarted belongingness, negative future disposition, felt stigma, suicidal ideation, and suicide attempts).

AIMS

This study aimed to examine whether suicide-related correlates differ significantly as a function of disability type.

METHODS

Individuals with mobility and vision disabilities (N = 102) completed semistructured interviews and online-based questionnaires. Analysis of variance/analysis of covaiance and Fisher's exact tests were conducted to examine whether mean levels of suicide-related correlates differed significantly between individuals with blindness/low vision (n = 63) versus mobility-related (n = 39) disabilities.

RESULTS

No significant between-group differences were observed for most outcomes; however, individuals with vision disabilities reported higher mean levels of felt stigma and positive future disposition than those with mobility-related disabilities.

LIMITATIONS

The limited representation of disabilities among participants precludes generalization to individuals with other forms of disability and the cross-sectional design prevents inference about causality.

CONCLUSIONS

Interventions targeting cognitive processes that underlie suicide risk may be applicable to people with mobility and vision disabilities.

Examining associations between suicidal desire, implicit fearlessness about death, and lifetime frequency of suicide attempts

INTRODUCTION

Suicide models propose that the capability for suicide, such as fearlessness about death (FAD), is necessary for the transition from suicidal desire to a suicide attempt. Most studies have relied on self-report methods to assess FAD. However, this research has produced equivocal results. As individuals may have limited awareness of learned or pre-existing associations between fearlessness and death, implicit measures of FAD hold promise. This study used a novel implicit association test (IAT), the IAT-FAD, to examine associations between suicidal desire, implicit FAD, and lifetime suicide attempt frequency.

METHODS

Patients in residential substance use treatment (N = 75), a population with increased suicide risk and exposure to painful and provocative events, completed the IAT-FAD and assessments of suicidal desire and past suicide attempts.

RESULTS

Implicit FAD moderated the association between suicidal desire and lifetime frequency of suicide attempts associated with an intent to die and requiring medical attention (although not ambivalent suicide attempts). Suicidal desire related to medically attended suicide attempts only at high implicit FAD levels, and to suicide attempts with a clear intent to die only at high or mean implicit FAD levels.

CONCLUSION

Results provide initial support for the relevance of implicit measures of FAD for understanding suicide risk.

Reduced working memory performance in PTSD and suicide among veterans presenting for treatment

Suicide is among the leading causes of death in the United States, underscoring the continued need to understand the mechanisms underlying suicide risk. A growing body of research has examined the role of working memory deficits in suicidal thoughts and behaviors (STBs), yet little research has evaluated putative pathways via which working memory impairments may heighten suicide risk. Elevated posttraumatic stress symptoms (PTSS) represent one plausible mechanism through which poor working memory performance may increase STBs. The present study utilized data from 140 treatment-seeking veterans who presented for an intake evaluation in the PTSD Clinical Team of a large VA Medical Center. Veterans completed self-report measures, a semi-structured PTSD evaluation, and a digit span working memory test. In addition to concurrent suicidal ideation assessed during the intake, additional information regarding past suicide attempts, presence of a safety plan, documentation of past suicidal behaviors, and engagement with suicide crisis lines were collected via electronic medical records. Consistent with hypotheses, a significant indirect path emerged such that poor working memory performance predicted greater suicidal ideation, greater likelihood of a past suicide attempt, and greater latent suicide risk via increased PTSS. However, no direct effect of working memory on STBs or indirect paths of PTSS on STBs via working memory emerged. These findings suggest that the relation between working memory and STBs may be explained by PTSS severity.

Diminished body trust uniquely predicts suicidal ideation and nonsuicidal self-injury among people with recent self-injurious thoughts and behaviors

INTRODUCTION

Self-injurious thoughts and behaviors (SITBs) are difficult to predict, and novel risk factors must be identified. While diminished interoception is associated with SITBs cross-sectionally, the current study assesses whether multiple measures of interoception predict future SITBs.

METHODS

Adults (N = 43) with recent SITBs completed assessments of interoception during a baseline visit. Participants then completed biweekly assessments for 6 months in which they reported the presence and severity/frequency of suicidal ideation and nonsuicidal self-injury (NSSI).

RESULTS

Multilevel models were performed, where baseline interoceptive measures predicted presence and severity/frequency of suicidal ideation and NSSI at follow-up. The Multidimensional Assessment of Interoceptive Awareness (MAIA) Trusting subscale was the only significant predictor of the presence/severity of suicidal ideation. The MAIA Trusting, Emotional Awareness, and Body Listening subscales significantly predicted the presence of NSSI. The MAIA Emotional Awareness subscale and the Body Perception Questionnaire significantly predicted NSSI frequency.

DISCUSSION

Diminished body trust predicted both suicidal ideation and NSSI, indicating a potential shared risk pathway. However, two interoception measures (Body Listening subscale and Body Perception Questionnaire) were associated with NSSI only, indicating potentially unique risk pathways. Given the differential associations between interoception measures and SITBs, results highlight the importance of clearly defining how interoception is measured.

Suicide plan prevalence, recurrence, and longitudinal association with nonfatal suicide attempt

BACKGROUND

Each year, millions of people develop suicide plans. These plans are assumed to indicate imminent suicide risk, yet this has rarely been tested. The present study seeks to address two questions: (1) how prevalent are specific thoughts of suicide plans among individuals with a history of suicidal thoughts and behaviors and (2) do suicide plans confer risk of future suicide attempts in the short term?

METHODS

Secondary data analysis was performed on a longitudinal dataset (N = 1021). Prevalence and frequencies of suicide planning features (i.e., method, time, place) at baseline and 3, 14, and 28 days post-baseline were calculated. Logistic regressions were conducted to assess whether suicide plans confer risk of suicide attempts across a 28-day follow-up period.

RESULTS

Suicide planning more commonly involved thoughts of method than place and/or time. High variability in suicide planning was evident and thoughts of suicide plans frequently recurred. Contrary to assumptions, suicide plans displayed weak associations with nonfatal suicide attempt across the 28-day follow-up period.

CONCLUSIONS

Suicide plans appear heterogeneous in nature. They do not appear to play a strong role in predicting nonfatal suicide attempts. Re-evaluation of the central role that suicide plans occupy within clinical risk assessments may be warranted.

Assessment of acute and non-acute suicide crisis symptoms: Validation of the Korean version of the acute suicidal affective disturbance inventory

Suicide risk assessment is predominantly based on assessing current/recent suicidal ideation and past suicidal behavior. However, suicidal ideation and lifetime suicide attempt are poor predictors of imminent suicide risk or crisis. The acute suicidal affective disturbance inventory-lifetime (ASADI-L) was developed to assess symptoms of acute suicidal affective disturbance, which includes a drastic increase in suicidal intent, perceptions of social and/or self-alienation, hopelessness, and overarousal. However, the ASADI-L has not yet been validated in a Korean population. Also, the ASADI-L has only been validated for people who experience a drastic increase in suicidal intention over the course of hours or days (i.e., the acute suicidal intention group) and not validated for those who experience suicidal intention for a longer period (i.e., the non-acute suicidal intention group). Thus, the aims of this study were to (1) validate the ASADI-L in a sample of Korean community adults; and (2) compare clinical characteristics of the acute and non-acute suicidal intention groups. Among 1,675 community adults, data from 682 participants who reported a lifetime drastic increase in suicidal intent were analyzed. Results indicated that the ASADI-L has relevant reliability, validity, and a unidimensional factor structure. The acute suicidal intention group had higher ASAD symptoms as well as clinical symptoms than the non-acute group, but the two groups did not differ in history of suicide attempt. Overall, these findings suggest that the ASADI-L is a valid measure of acute and non-acute suicidal affective disturbance among Korean adults. Further investigation of the differences in acute and non-acute suicide risk is warranted.

Suicide Risk Among Military Veterans in the Southwestern United States Before and During the COVID-19 Pandemic

INTRODUCTION

Military Veterans have an increased risk of suicide compared to the general population, but less is known about changes in risk with the onset of the COVID-19 pandemic, or whether any changes have been moderated by psychiatric or demographic factors. The primary objective was to test the hypothesis that the likelihood of suicide attempt or death by suicide was stable during the first year of the pandemic versus the preceding year for the full sample. A second objective was to test the hypothesis that, in contrast, risk increased for Veteran subgroups characterized by traditional risk factors (e.g., psychiatric diagnosis).

MATERIALS AND METHODS

We extracted electronic health record data for 771,570 Veterans who received one or more health care visits between March 13, 2019, and March 12, 2021, at eight VA hospitals across the southwestern United States. Primary outcome measures were suicide attempts and deaths by suicide. Predictor variables included psychiatric diagnoses and demographic factors.

RESULTS

Multivariable models indicated that the odds of death by suicide did not change during the first year of the COVID-19 pandemic, while the odds of making a suicide attempt declined. Veterans treated for major depression were at heightened risk for attempting suicide in both years, but the association was smaller during the pandemic than the year prior. In contrast, the relative risk of attempt for Veterans who were never married and Veterans treated for a non-alcohol, non-opioid substance-use disorder increased during the pandemic.

CONCLUSIONS AND RELEVANCE

The findings suggest that the pandemic has not led to an increase in suicidal behavior, which is consistent with other studies, although the degree of decline varied across diagnostic and demographic groups. Further longitudinal research is needed to evaluate whether the prolonged nature of COVID-19 may lead to changes in risk over time.

Assessing the clinical utility of MMPI-2-RF interpersonal theory of suicide proxy indices in psychiatric hospitalization setting

INTRODUCTION

The Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF Ben-Porath & Tellegen, 2008/2011) has been applied to suicide risk assessment through derived proxy indices of perceived burdensomeness, thwarted belongingness, and the acquired capability for suicide (Anestis et al., 2018, Joiner, 2005). However, limited research has examined the clinical utility of these proxy indices outside the outpatient setting. This study examined the performance of these proxy indices in identifying past-month suicide ideation intensity and attempts upon admission to a psychiatric inpatient program and changes in suicidal ideation intensity at discharge. We expected these indices and their interaction would be associated with suicide ideation intensity and attempts at baseline and with a lack of significant improvement in suicide ideation intensity at discharge, including when controlling for MMPI-2-RF Suicide/Death Ideation (SUI) scale scores.

METHOD

Participants were 1007 patients in a private inpatient psychiatric hospital in the southwestern United States, 968 of whom completed study measures at admission and discharge. Participants were administered the C-SSRS and MMPI-2-RF upon admission, while the C-SSRS was administered again prior to discharge. A series of moderation analyses were conducted to examine the main and interaction effects of the MMPI-2-RF derived proxy indices on suicidal ideation intensity and suicide attempts at admission. Logistic regression analyses were conducted to examine whether MMPI-2-RF proxy index scores at admission were associated with changes in suicidal ideation intensity at discharge.

RESULTS

Neither the proxy indices nor their interaction was associated with all study outcomes. The acquired capability for suicide proxy index and its interaction with other indices were not associated with suicide attempt status at admission. However, high thwarted belongingness proxy index scores were associated with greater suicidal ideation intensity at admission; high perceived burdensomeness proxy index scores were indicative of a lack of significant change in suicide ideation intensity at discharge.

CONCLUSION

These results indicate a need to further examine these proxy indices in high acuity samples.

Comparative clinical utility of screening for Suicide Crisis Syndrome versus suicidal ideation in relation to suicidal ideation and attempts at one-month follow-up

INTRODUCTION

Suicidal ideation (SI) has numerous limitations in predicting suicidal behavior. The Suicide Crisis Syndrome (SCS) is proposed as an alternative method of detecting risk. This study compares the relative utility of SI and SCS in statistically predicting SI and behaviors at one-month follow-up.

METHODS

382 psychiatric patients (98 inpatients, 284 outpatients) completed baseline measures and provided information about suicide-related outcomes one month later. Participants were grouped based on responses to measures assessing SCS and SI.

RESULTS

Rates of follow-up suicidal behavior were significantly higher among those reporting both SCS and SI (22.2%) than those reporting SI alone (6.0%) or neither SCS nor SI (0.9%). SCS alone (8.3%) had descriptively, but not statistically, higher rates of suicidal behavior than those with neither SCS nor SI, and did not differ from SI alone and the combination of SCS and SI. Those reporting SI-with and without SCS-had higher levels of follow-up suicidal thoughts than those without SI.

CONCLUSION

The SCS was equivalent to SI, and incrementally informative alongside SI, in detecting individuals at risk of future suicidal behavior, whereas SI was more strongly related to future SI than SCS. The combination of SCS and SI may be clinically useful in detecting individuals who are at risk for suicide.

Firearms Access among Pediatric Patients at Risk for Suicide

BACKGROUND

Approximately 2,900 youth who die by suicide each year in the United States use a firearm. To inform lethal means safety counseling efforts, this study aimed to describe firearm access among youth deemed at risk for suicide in pediatric medical settings.

METHODS

Youth who presented to one of four urban pediatric medical centers were screened for suicide risk and access to firearms. Suicide risk was determined by a positive screen on the Ask Suicide-Screening Questions (ASQ) tool. Firearm access was assessed via a structured questionnaire.

RESULTS

This secondary analysis analyzed data from 1065 youth aged 10 to 17 years. Overall, 110 (10.3%) participants screened positive for suicide risk. Among those at risk, 28% (31/110) reported guns kept in or around their home, 8% (9/110) had access to a firearm, and 5% (6/110) reported that bullets were not stored separately from the guns.

CONCLUSIONS

Over a quarter of youth at risk for suicide reported a firearm stored in or around their home. To ensure the safety of young people at risk for suicide, clinicians should assess whether youth have access to firearms and conduct lethal means safety counseling with youths, as developmentally appropriate, and their parent/caregivers.HIGHLIGHTS28% of pediatric patients deemed "at risk" for suicide in this study reported a firearm kept in or around their home.Among youth at risk for suicide, 8% reported having access to a firearm.These results add further evidence that it is important for clinicians to conduct lethal means safety counseling with patients and their families.

Examining Factors Influencing the Differential Reporting of Suicide Attempt History Among Undergraduates at Elevated Suicide Risk

AIM

Prior studies suggest that individuals may respond inconsistently to different assessments of suicide attempt (SA) history; yet, little is known regarding why inconsistent reporting of SA history may occur. The overarching goal of this study was to examine individuals' self-reported reasons for inconsistently responding to different self-report measures designed to assess SA history.

METHODS

Young adults who reported a lifetime history of suicidal ideation (N = 141) completed three different self-report measures of SA history: the (1) Beck Scale for Suicide Ideation (BSS), (2) Suicidal Behaviors Questionnaire-Revised (SBQ-R), and (3) Self-Injurious Thoughts and Behaviors Interview-Short Form (SITBI-SF). All measures were administered in a randomized order to control for potential order effects. Descriptive statistics were used to test study aims.

RESULTS

Of the sample, 75% of participants denied an SA history across all three measures, 16% reported an SA history across all measures ("consistent responders"), and 9% responded inconsistently to SA history measures ("inconsistent responders"). Of the 9% (n = 12) of participants who inconsistently responded to SA history measures, the most commonly reported reasons for inconsistent reporting were that the definition of the term "attempt" was not made clear and that the participant did not read the SA history probes carefully.

CONCLUSION

Findings from this study underscore a need for increased efforts to improve SA history assessments.HIGHLIGHTSSome individuals may provide inconsistent responses across different suicide attempt measures.Confusion about the definition of a "suicide attempt" may lead to inconsistent responding.Further research is needed to improve our assessment of suicide attempt history.

Differential disclosure of suicidal intent to clinicians versus researchers: Associations with concurrent suicide crisis syndrome and prospective suicidal ideation and attempts

Several patient and setting characteristics have been found to predict disclosure of suicidality to clinicians versus researchers. Less understood, however, is whether differential disclosure of suicidality predicts concurrent indirect indicators of suicide risk and future suicide-related outcomes. The present study examined differential disclosure of suicidal intent in clinical versus research settings as a predictor of (1) concurrent symptoms of the Suicide Crisis Syndrome (SCS); and (2) suicidal ideation and attempts within one month in patients (n = 1039) and their clinicians (n = 144), who completed a battery of self-report and interview measures at baseline. Patients who reported suicidal intent to anyone had higher concurrent SCS symptoms than those who denied suicidal intent, with no differences between those who reported intent to clinicians versus researchers only. Severity of suicidal ideation and rates of suicide attempts at one-month follow-up were higher among those who disclosed suicidal intent to a research assistant than among those who did not-regardless of whether suicidal intent was disclosed to their clinician. Overall, an improved understanding of the factors contributing to differential disclosure will improve both scientific inquiry and patient safety.

Future Well-Being Among U.S. Youth Who Attempted Suicide and Survived

To what extent does a suicide attempt impair a person's future well-being? We estimated the prevalence of future well-being (FWB) among suicide attempt survivors using a nationally representative sample of 15,170 youths. Suicide attempt survivors were classified as having high FWB if they reported (a) a suicide attempt at Wave I, (b) no suicidal ideation or attempts over the past year at Wave III (7 years after), and (c) a well-being profile at or above the top quartile of nonsuicidal peers. Seventy-five of 574 suicide attempt survivors (∼13%) met criteria for FWB at Wave III, compared to 26% of nonsuicidal peers. Wave I well-being levels, not depressive symptoms, predicted the likelihood of FWB at Wave III (OR = 1.23, 95% CI [1.05, 1.44], p < .05). In conclusion, a nonfatal suicide attempt reduced but did not preclude FWB in a large national sample. The observation that a segment of the population of suicide attempt survivors achieves FWB carries implications for the prognosis of suicidal behavior and the value of incorporating well-being into investigations of suicide-related phenomena.

When people die by suicide: Introducing unacceptable loss thresholds as a potential missing link between suicide readiness states and actively suicidal clinical states

INTRODUCTION

Contemporary models of suicide have largely overlooked why a person at high risk for suicide attempts suicide at a specific time. We propose the construct of unacceptable loss thresholds (i.e., a person's tolerance limit for a negative life event, which if violated results in an increase in suicide risk), which addresses many paradoxes in the literature related to suicide triggers. The aim of this paper is to provide preliminary proof of concept and to stimulate replication and further empirical study.

METHODS

We recruited an online community sample of individuals with a suicide attempt history (n = 144). These individuals answered questions about the time leading up to their most recent suicide attempt.

RESULTS

The majority (70.8% yes; 18.1% cannot remember; 11.1% no) reported creating a threshold of unacceptable loss, and that relatively small events were enough to trigger feelings that life was not worth living (63.9% yes; 30.6% maybe; 5.6% no). Further, the majority (57.6% yes; 21.5% yes, but only if asked; 20.8% - no) reported they would be willing to tell their therapist/doctor about their thresholds of unacceptable loss.

CONCLUSION

The construct of unacceptable loss deserves further empirical inquiry. Individuals contemplating suicide set them and if the loss occurs, it may trigger suicidal action in suicide ready individuals. Thresholds could provide risk assessment and safety planning data currently being overlooked.

A comparative study of suicidal and nonsuicidal self-injury characteristics in heterosexual versus sexual minority females

Sexual minorities are at heightened risk for nonsuicidal self-injury (NSSI), suicidal ideation and attempts. We tested whether sexual minority and heterosexual females differ on these characteristics. Sexual minority females (n = 45) had higher lifetime frequency of NSSI and higher thwarted belonginess compared to heterosexual females (n = 47). These specific factors may contribute to the higher rates of suicide attempts among sexual minorities than heterosexual individuals.

Follow-Up Mental Health Care in Youth and Young Adults With Type 1 Diabetes After Positive Depression Screen and/or Suicidal Ideation

Individuals with type 1 diabetes have higher rates of depression and suicidal ideation than the general population, and symptoms of depression are often associated with higher A1C levels and complications. This study evaluated mental health follow-up rates in youth and young adults with type 1 diabetes who screened positive for depressive symptoms or suicidal ideation and identified differences between those who obtained follow-up mental health care and those who did not. Specifically, males were less likely to obtain follow-up, and those who had mental health follow-up had decreasing A1C over the following year. These findings suggest increased assistance and monitoring are needed to ensure follow-up mental health care is obtained.

[Case Report on the Treatment of Inner Restlessness with Biofeedback and Behavior Therapy]

BACKGROUND

Inner restlessness is a frequently mentioned symptom in psychiatric-psychotherapeutic clinical practice, from which patients with various mental illnesses suffer.

METHOD

A patient with major depression was treated with a total of eight biofeedback sessions with the physiological parameter heart rate variability and three behavioral therapy sessions. Questionnaires were used to assess the symptom of inner restlessness and a possible success of the therapy.

RESULTS

Inner restlessness, ability to relax, disease burden and self-efficacy improved significantly over the 3-week treatment period.

DISCUSSION

Inner restlessness could be treated surprisingly successfully.

CONCLUSION

More importance should be given to the treatment of inner restlessness.

A call for change from impersonal risk assessment to a relational approach: professionals' reflections on the national guidelines for suicide prevention in mental health care in Norway

PURPOSE

The purpose of the study is to explore how professionals working with suicide prevention experience the influence of the national guidelines on mental healthcare, and to gather recommendations for which steps to take next.

METHODS

This is a qualitative study with an explorative design. We interviewed 22 professionals responsible for implementing suicide prevention action plans and guidelines, and/or conducting relevant research. We analysed the data by means of thematic analysis.

RESULTS

We found that the participants had an ambivalent view on risk assessment-it may be a tool, but it may also compromise other important aspects in prevention. Moreover, the possibility of liability has resulted in the need for self-protection. Instead, the participants recommended a relational approach to suicide prevention.

CONCLUSIONS

We found that the emphasis on standardized suicide risk assessment has negatively influenced suicide prevention in mental healthcare, and an approach emphasizing relational aspects is recommended. However, the prevailing objectifying concept of knowledge, the epistemological debate and the emergence of the New Public Management ideology may obstruct a fundamental emphasis on relationships. A paradigm shift in mental healthcare is called for with respect to the concept of knowledge, which forms our understandings and practices.

Association Between Disability and Suicide-Related Outcomes Among U.S. Adults

INTRODUCTION

Although research has analyzed the sociodemographic and socioeconomic risks for suicide, only recently has suicide risk for people with disabilities been examined. This study investigates the associations between disability and distinct suicide-related outcomes, including suicidal ideation, suicide planning, and suicide attempt.

METHODS

This nationally representative, cross-sectional study comprised secondary analyses of the 2015-2019 National Survey on Drug Use and Health conducted in 2020 (N=198,640, representing 229,556,289 U.S. adults). Disability status comprised the presence of any disability; hearing, vision, mobility, cognitive, complex activity, or ≥2 limitations; and 1, 2, 3, 4, or ≥5 limitations. Suicide-related outcomes in the past year included none, suicidal ideation only, suicide planning, and suicide attempt. Multivariable logistic regression was applied to estimate the AORs.

RESULTS

Overall, 19.8% reported any disability. Results showed that people with disabilities were significantly more likely than those without disabilities to report suicidal ideation (AOR=2.13, 95% CI=1.93, 2.36), suicide planning (AOR=2.66, 95% CI=2.27, 3.11), and suicide attempt (AOR=2.47, 95% CI=2.05, 2.98). Furthermore, individuals within each limitation count group were significantly more likely than people without disabilities to report suicide-related outcomes (p<0.001), with the largest magnitudes among those with ≥5 limitations for suicidal ideation (AOR=3.80, 95% CI=2.32, 6.23), suicide planning (AOR=6.45, 95% CI=3.52, 11.80), and suicide attempt (AOR=8.19, 95% CI=4.45, 15.07).

CONCLUSIONS

People with various types of functional disabilities had an elevated risk for suicide-related outcomes, compared with people without disabilities. The more limitations a person had progressively increased their risk. These findings call for focused attention to the mental health of people with disabilities, including suicide prevention efforts that accommodate their needs.

Validity of the modular assessment of risk for imminent suicide in predicting short-term suicidality

OBJECTIVE

The Modular Assessment of Risk for Imminent Suicide (MARIS) is a clinical assessment tool, consisting of four modules assessing (1) a pre-suicidal cognitive-affective state (Module 1); (2) patients' attitudes toward suicide (Module 2); (3) clinicians' assessment of suicide risk factors (Module 3); and (4) clinicians' emotional responses to patients (Module 4) that assesses short-term suicide risk. Initial evidence provided evidence for its reliability and concurrent validity. The present study extended these findings by examining the MARIS's predictive validity in relation to suicidal thoughts and behaviors at one-month follow-up.

METHODS

A sample of 1039 psychiatric patients (378 inpatients, 661 outpatients) and their clinicians (N = 144) completed a battery of measures at baseline; 670 patients completed the one-month follow-up assessment.

RESULTS

MARIS total scores predicted suicidal thoughts and behaviors at one-month follow-up, even after controlling for baseline suicidal thoughts and behaviors. Moreover, both Module 1 and the Distress subscale of Module 4 were uniquely associated with suicidal thoughts and behaviors at one-month follow-up, controlling for baseline suicidal thoughts and behaviors. Modules 2 and 3, on the other hand, exhibited poor internal consistency.

CONCLUSION

Overall, both patient- and clinician-rated indices are uniquely predictive of suicidal thoughts and behaviors at one-month follow-up, highlighting the need for integrating clinicians' emotional responses into suicide risk assessment. Pending replication and extension of these findings in external samples, a briefer, two-module version of MARIS (MARIS-2) may be such an integrative, psychometrically sound, and clinically useful instrument that can be utilized to assess short-term suicide risk.

Interoceptive dysfunction indicates presence and severity of self-injurious behaviors in a clinically severe transdiagnostic sample

Interoceptive dysfunction (ID) is associated with self-injurious behaviors, as disconnection from the body is thought to enable bodily harm. This study tested differences in ID among those with and without history of self-injurious behaviors, as well as the relationship between ID and lethality of past suicide attempts. Adults (N = 344; 61.3% female; mean age 27.68) seeking psychological treatment completed self-report measures and clinical interviews during intake at a community-based clinic. Overall symptom severity was substantial (e.g., approximately 40% reported current suicidal ideation and two-thirds met a clinical cut-off score of ≥ 16 on the Beck Depression Inventory). Orthogonal contrasts were used to test whether mean levels of ID differed across lifetime self-injurious behavior groups. Attempt lethality was regressed on interoceptive dysfunction, covarying depressive symptom severity, age, and gender. Participants with suicide attempt history demonstrated greater ID than those without. Participants who had engaged in non-suicidal self-injury demonstrated greater ID than those with no history of self-injurious behaviors. Greater ID was associated with higher lethality of past suicide attempt, above demographic and clinical covariates. ID may have transdiagnostic relevance for risk assessment and management of self-injurious behaviors.

Suicide Notes, Attempts, and Attempt Lethality During Episodes of Ideation Among Suicidal Soldiers and Marines

OBJECTIVE

Suicide remains a significant public health problem among military personnel despite expanded suicide prevention efforts over the last two decades. It is important to understand the behavioral antecedents of suicide, including the writing of a suicide note, to inform efforts to identify imminent risk. However, the completion of a suicide note increasing the likelihood of making a suicide attempt (SA) and predicting a higher lethality SA during episodes of suicidality have not been evaluated.

METHOD

To determine whether or not the completion of a suicide note increased the likelihood of making a SA during a given episode of suicidal ideation (current or worst) and predicted a higher lethality SA, we conducted secondary data analysis with a sample of 657 help-seeking, active-duty U.S. Soldiers and Marines. We hypothesized that service members who completed a suicide note would be more likely to make a SA during that given episode of suicidality and make a higher lethality SA.

RESULTS

Completion of a suicide note increased the likelihood of making a SA in both current and worst episodes of suicidal ideation. Additionally, writing a suicide note predicted making a higher lethality SA during a service member's current episode of ideation but not their worst episode.

CONCLUSIONS

This is the first study to examine note-writing behavior during episodes of suicidal ideation rather than following a suicide death or attempt, demonstrating a non-trivial number (17%) had written a suicide note and this increased the likelihood of making a SA and a higher lethality SA.HIGHLIGHTSThe first study of suicide notes during periods of ideation regardless of attempt.A suicide note written during an episode of ideation predicted making an attempt.A suicide note predicted making a more lethal suicide attempt.

Raising doubt about the anticipated consequences of suicidal behavior: Evidence for a new approach from laboratory and real-world experiments

OBJECTIVE

Converging evidence from basic science and experimental suicide research suggest that the anticipated consequences of suicide may have direct causal effects on suicidal behavior and accordingly represent a promising intervention target. Raising doubt about individuals' desirable anticipated consequences of suicide may be one means of disrupting this target. We tested this possibility across two complementary experimental studies.

METHOD

Study 1 tested the effects of raising doubt about desirable anticipated consequences on virtual reality (VR) suicide in the lab, randomizing 413 participants across four conditions. In Study 2, 226 suicidal adults were randomized to an anticipated consequence manipulation or control condition then re-assessed at 2- and 8-weeks post-baseline.

RESULTS

In Study 1, anticipating that engaging in VR suicide would guarantee a desirable outcome significantly increased the VR suicide rate; conversely, raising doubt about the desirable anticipated consequences significantly reduced the VR suicide rate. In Study 2, raising doubt about the anticipated consequences of attempting suicide by firearm significantly reduced the perceived lethality of firearms as well as self-predicted likelihood of future suicide attempts, with effects sustained at 2-week follow-up.

CONCLUSIONS

Findings suggest that raising doubt about desirable anticipated consequences of suicide merits further research as one potential approach to inhibit suicidal behavior.

Suicidal thoughts, behaviors, and event-related potentials: A systematic review and meta-analysis

Suicidal thoughts and behaviors (STBs) are thought to result from, at least in part, abnormalities in various neural systems. Event-related potentials (ERPs) are a useful method for studying neural activity and can be leveraged to study neural deficits related to STBs; however, it is unknown how effective ERPs are at differentiating various STB groups. The present meta-analysis examined how well ERPs can differentiate (a) those with and without suicidal ideation, (b) those with and without suicide attempts, (c) those with different levels of suicide risk, and (d) differences between those with suicide attempts versus those with suicidal ideation only. This meta-analysis included 208 effect sizes from 2,517 participants from 27 studies. We used a random-effects meta-analysis using a restricted maximum likelihood estimator with robust variance estimation. We meta-analyzed ERP-STB combinations that had at least three effect sizes across two or more studies. A qualitative review found that for each ERP and STB combination, the literature is highly mixed. Our meta-analyses largely did not find significant relationships between STBs and ERPs. We also found that the literature is likely severely underpowered, with most studies only being sufficiently powered to detect unrealistically large effect sizes. Our results provided little-to-no support for a reliable relationship between the ERPs assessed and STBs. However, the current literature is severely underpowered, and there are many methodological weaknesses that must be resolved before making this determination. We recommend large-scale collaboration and improvements in measurement practices to combat the issues in this literature.
