Implicit Measure of Life/Death Orientation Predicts Response of Suicidal Ideation to Treatment in Psychiatric Inpatients

Implicit Identification with Death, Clinician Evaluation and Suicide Ideation among Adolescent Psychiatric Outpatients-The Mediating Role of Depression

Implicit identification with death (i.e., subconsciously self-associating oneself with death), measured by the Death-Suicide Implicit Association Test (D/S-IAT), is associated with Suicide Ideation (SI). Our understanding of the mechanisms underlying this association is limited. The current study examined (1) the mediating role of depression between D/S-IAT and recent SI and (2) the association between SI, D/S-IAT, and clinician evaluation of SI among a clinical sample of adolescents. 148 adolescents aged 10-18 years (69.4% female) from two outpatient clinics were assessed at intake. Participants completed D/S-IAT and self-report measures for recent SI and depression during intake. Findings indicate that depression is a mediator between D/S-IAT and recent SI, controlling for gender, site differences, and past suicidal thoughts and behaviors. D/S-IAT and clinician evaluation were correlated with recent SI but not beyond depression. Our findings highlight the importance of examining the underlying psychological mechanisms regarding the association between D/S-IAT and suicide.

Alterations in performance and discriminating power of the death/suicide implicit association test across the lifespan

The Death/Suicide Implicit Association Test (d/s-IAT) has differentiated individuals with prior and prospective suicide attempts in previous studies, however, age effects on test results remains to be explored. A three-site study compared performance on the d/s-IAT among participants aged 16-80 years with depression and prior suicide attempt (n = 82), with depression and no attempts (n = 80), and healthy controls (n = 86). Outcome measures included the standard difference (D) score, median reaction times, and error rates. Higher D scores represent a stronger association between death/suicide and self, while lower scores represent a stronger association between life and self. The D scores differed significantly among groups overall. Participants with depression exhibited higher scores compared to healthy controls, but there was no difference between participants with and without prior suicide attempts(F[2,242]=8.76, p<.001). Response times for participants with prior attempts differed significantly from other groups, with no significant differences in error rates. The D score was significantly affected by age (β =-0.007, t = 3.65, p<.001), with slowing of response times in older ages. Results suggest reaction time d/s-IAT D scores may not distinguish implicit thinking about suicide as response times slow with age, but slowed response times may be sensitive to suicide risk potentially indicating basic information processing deficits.

Predicting suicidal ideation in psychiatrically hospitalized veterans using the death/suicide Implicit Association Test: A prospective cohort study

INTRODUCTION

We investigated whether the Death/Suicide Implicit Association Test (D/S-IAT) predicted suicidal ideation (SI) in psychiatric inpatients.

METHODS

One hundred eighty veterans admitted for either SI or suicidal behavior (SB) (the primary sample) (N = 90) or alcohol detoxification (N = 90) completed the D/S-IAT and scales measuring SI. Correlation and regression coefficients were measured between the D/S-IAT (as a full-scale or dichotomized score [D > 0]) and self-reported current or imminent SI (over the next 1-3 days).

RESULTS

In the primary sample, the full-scale D/S-IAT was significantly correlated with the intensity of current SI (r = 0.22, p = 0.04) and especially with wishes to be dead (r = 0.35, p < 0.001). The intensity of imminent SI was significantly predicted by the full-scale (p = 0.02) and dichotomized D/S-IAT score (p = 0.05) in a multiple regression model. However, no significant associations were observed when both the D/S-IAT score and current (present/absent) or imminent SI (occurred/did not occur) were dichotomous measures. In participants receiving alcohol detoxification, the D/S-IAT significantly predicted only wishes to be dead (r = 0.33, p < 0.001).

CONCLUSION

The full-scale D/S-IAT score predicted the current intensity of wishes to be dead in both inpatient samples, and current and imminent SI in participants admitted for SI/SB. The dichotomized D/S-IAT score did not predict the simple occurrence of SI.

Toward objective characterizations of suicide risk: A narrative review of laboratory-based cognitive and behavioral tasks

Although suicide is a leading cause of preventable death worldwide, current prevention efforts have failed to substantively mitigate suicide risk. Suicide research has traditionally relied on subjective reports that may not accurately differentiate those at high versus minimal risk. This narrative review supports the inclusion of objective task-based measures in suicide research to complement existing subjective batteries. The article: 1) outlines risk factors proposed by contemporary theories of suicide and highlights recent empirical findings supporting these theories; 2) discusses ongoing challenges associated with current risk assessment tools and their ability to accurately evaluate risk factors; and 3) analyzes objective laboratory measures that can be implemented alongside traditional measures to enhance the precision of risk assessment. To illustrate the potential of these methods to improve our understanding of suicide risk, the article reviews how acute stress responses in a laboratory setting can be modeled, given that stress is a major precipitant for suicidal behavior. More precise risk assessment strategies can emerge if objective measures are implemented in conjunction with traditional subjective measures.

Implicit identification with death detects and predicts short-term suicide risk among adolescents discharged from the emergency room

BACKGROUND

Implicit identification with death, measured by the Death-Suicide-Implicit Association Test (D/S-IAT), has been found to predict long-term suicide risk among adolescents. However, previous studies did not examine the predictive utility of D/S-IAT on short-term suicide risk trajectories among adolescents, especially during the critical period following discharge from the emergency room (ER) due to suicide behaviors.

OBJECTIVE

This study examined the ability of the D/S-IAT to discriminate and predict suicide risk trajectories during the month following initial suicide risk assessment, among adolescents recently discharged from the ER.

METHODS

One hundred and fifteen adolescents aged 9-18 years (77.4% female) were assessed at clinic intake. All participants completed D/S-IAT and self-report measures for suicide risk, depression, and anxiety during intake and 1-month follow-up.

RESULTS

The D/S-IAT distinguished and predicted participants with continued heightened suicide risk at follow-up, above and beyond depression, anxiety, and suicide risk level at intake.

CONCLUSIONS

Along with conventional measures, D/S-IAT may be utilized to predict short-term suicide risk during post-ER discharge.

Nighttime Sleep Quality and Daytime Sleepiness Predicts Suicide Risk in Adults Admitted to an Inpatient Psychiatric Hospital

As sleep problems have been identified as an important, yet understudied, predictor of suicide risk, the present study analyzed the relationship between daytime sleepiness and nighttime sleep disturbance in a high-risk population of adults admitted to an inpatient psychiatric hospital. Objectives were to (1) examine the time course of subjective daytime sleepiness, nighttime sleep disturbance, and suicide risk throughout inpatient psychiatric treatment, (2) examine pre- to post-treatment changes in sleep disturbance with treatment as usual in an inpatient psychiatric setting, and (3) investigate whether daytime sleepiness and nighttime sleep disturbance predicted suicide risk above and beyond anxiety and depression. Participants were 500 consecutively admitted adults admitted to an intermediate length of stay (4-6 weeks) inpatient psychiatric hospital (47% female; 18-87 years of age). Measures of sleep, suicide risk, depression, and anxiety were completed at admission, weeks 1 through 4, and at discharge. Latent growth curve modeling (LGM) and hierarchal linear modeling (HLM) were conducted. The LGM analysis demonstrated that daytime sleepiness, nighttime sleep disturbance, and suicide risk all improved throughout inpatient treatment. Further, HLM showed that daytime sleepiness predicted suicide risk above and beyond symptoms of anxiety, depression, major sleep medications, and prior suicidal ideation and attempts, while nighttime sleep disturbance predicted suicide risk above and beyond symptoms of anxiety, major sleep medications, and prior suicidal ideation and attempts. Findings indicate the need to reevaluate safety protocols that may impact sleep, particularly that may increase daytime sleepiness, and to develop evidence-based sleep interventions for individuals admitted to inpatient psychiatric hospitals.

A comparison of self-reported risk and protective factors and the death implicit association test in the prediction of future suicide attempts in adolescent emergency department patients

BACKGROUND

Concerns have been raised about the utility of self-report assessments in predicting future suicide attempts. Clinicians in pediatric emergency departments (EDs) often are required to assess suicidal risk. The Death Implicit Association Test (IAT) is an alternative to self-report assessment of suicidal risk that may have utility in ED settings.

METHODS

A total of 1679 adolescents recruited from 13 pediatric emergency rooms in the Pediatric Emergency Care Applied Research Network were assessed using a self-report survey of risk and protective factors for a suicide attempt, and the IAT, and then followed up 3 months later to determine if an attempt had occurred. The accuracy of prediction was compared between self-reports and the IAT using the area under the curve (AUC) with respect to receiver operator characteristics.

RESULTS

A few self-report variables, namely, current and past suicide ideation, past suicidal behavior, total negative life events, and school or social connectedness, predicted an attempt at 3 months with an AUC of 0.87 [95% confidence interval (CI), 0.84-0.90] in the entire sample, and AUC = 0.91, (95% CI 0.85-0.95) for those who presented without reported suicidal ideation. The IAT did not add significantly to the predictive power of selected self-report variables. The IAT alone was modestly predictive of 3-month attempts in the overall sample ((AUC = 0.59, 95% CI 0.52-0.65) and was a better predictor in patients who were non-suicidal at baseline (AUC = 0.67, 95% CI 0.55-0.79).

CONCLUSIONS

In pediatric EDs, a small set of self-reported items predicted suicide attempts within 3 months more accurately than did the IAT.

Implicit Cognition Tests for the Assessment of Suicide Risk: a Systematic Review

PURPOSE OF REVIEW

Suicide risk assessment is a challenge in clinical practice. Implicit measures may present with advantages with respect to explicit methods, and therefore may be useful for the assessment of suicide risk. We conducted a systematic review of 2 databases (PubMed and EMBASE) about implicit tests that measure suicide risk to explore their validity and reliability.

RECENT FINDINGS

Initial research revealed 321 articles. After the selection process, 31 articles were included in the review. The most death-related implicit cognition test used was the Death/Suicide Implicit association test (D/S IAT), followed by the Suicide Stroop Task. The Suicide Affect Misattribution Procedure (S-AMP) and the Death version of the Implicit Relational Assessment Procedure (D-IRAP) were also used. We found that the measures reviewed were generally valid for the assessment of past and future suicidal thoughts and behaviors, with statistically significant results regarding retrospective and prospective associations.

Conceptualizing death: How do suicidal adolescents view the end of their lives?

OBJECTIVE

Adolescence marks an important time to detect suicide risk, as suicidal ideation often emerges during this developmental period. Death-themed cognitions represent a promising domain of risk factors for suicidal ideation, but they have been understudied among adolescents. To address this knowledge gap, the present study examines the association between adolescents' attitudes and beliefs about death, hereafter referred to as death conceptualizations, and suicidal ideation.

METHODS

Seventy-four adolescents (12-19 years) completed a self-report measure assessing three types of death conceptualizations: Death Avoidance (i.e., suppression of death-related thoughts), Neutral Acceptance (i.e., belief that death is a natural part of life), and Escape Acceptance (i.e., belief that death is a viable escape from pain). Suicidal ideation was assessed at baseline, as well as 3 and 6 months later.

RESULTS

At baseline, suicidal adolescents endorsed higher Escape Acceptance and lower Death Avoidance. Suicidal and nonsuicidal adolescents did not differ in their degree of Neutral Acceptance. Death conceptualizations, especially Escape Acceptance, also predicted future suicidal ideation.

CONCLUSIONS

Initial findings suggest that suicidal adolescents are more likely to believe that death is a viable escape from pain and that this death-related cognition is a risk factor for suicidal ideation.

The death-implicit association test and suicide attempts: a systematic review and meta-analysis of discriminative and prospective utility

Suicide risk assessment involves integrating patient disclosure of suicidal ideation and non-specific risk factors such as family history, past suicidal behaviour, and psychiatric symptoms. A death version of the implicit association test (D-IAT) has been developed to provide an objective measure of the degree to which the self is affiliated with life or death. However, this has inconsistently been associated with past and future suicidal behaviour. Here, we systematically review and quantitatively synthesize the literature examining the D-IAT and suicide attempts. We searched psychINFO, Medline, EMBASE, and the Cochrane Central Register of Controlled Trials (CENTRAL) from inception until 9 February 2021 to identify publications reporting D-IAT scores and suicide attempts (PROSPERO; CRD42020194394). Using random-effects models, we calculated standardized mean differences (SMD) and odds ratios (ORs) for retrospective suicide attempts. We then calculated ORs for future suicide attempts. ORs were dichotomized using a cutoff of zero representing equipoise between self-association with life and death. Eighteen studies met our inclusion criteria (n = 9551). The pooled SMD revealed higher D-IAT scores in individuals with a history of suicide attempt (SMD = 0.25, 95% CI 0.15 to 0.35); however, subgroup analyses demonstrated heterogeneity with acute care settings having lower effect sizes than community settings. Dichotomized D-IAT scores discriminated those with a history of suicide attempt from those without (OR 1.38 95% CI 1.01 to 1.89) and predicted suicide attempt over a six-month follow-up period (OR 2.99 95% CI 1.45 to 6.18; six studies, n = 781). The D-IAT may have a supplementary role in suicide risk assessment; however, determination of acute suicide risk and related clinical decisions should not be based solely on D-IAT performance.

On loving thyself: Exploring the association between self-compassion, self-reported suicidal behaviors, and implicit suicidality among college students

Suicide is a major public health concern. It is unknown whether self-compassion is associated with suicide risk above and beyond suicide risk factors such as self-criticism, hopelessness, and depression severity. Participants: Participants were 130 ethnically diverse undergraduate college students. Methods: Participants completed self-report measures of self-compassion, self-criticism, hopelessness, depression severity, and suicidal behaviors, as well as an implicit measure of suicidality. Results: Self-compassion was significantly associated with self-reported suicidal behaviors, even when controlling for self-criticism, hopelessness, and depression severity. Self-compassion was not significantly associated with implicit suicidality. Conclusions: The findings suggest that self-compassion is uniquely associated with self-reported suicidal behaviors, but not implicit suicidality, and that self-compassion is a potentially important target in suicide risk interventions. Limitations and future research directions are discussed.

The relationship between suicide-specific rumination and suicidal intent above and beyond suicidal ideation and other suicide risk factors: A multilevel modeling approach

Suicide-specific rumination, characterized by perseveration on and difficulties disengaging from suicidal thoughts and ideas, has been linked to increased suicide risk; however, previous studies were limited by the use of a cross-sectional design and relatively lower risk samples. This study aimed to replicate and extend previous findings by examining the short-term longitudinal association between suicide-specific rumination and suicidal intent, controlling for numerous robust covariates, in a sample of community-based adults at high risk for suicide, who were recruited from suicide-related forums online. Ninety-one adults with significant suicidal ideation (M_age = 27.03, SD = 8.64; 53.8% female, 44.0% male, 1.1% non-binary, 1.1% transgender female) completed brief online self-report measures at six time-points, each three days apart. Multilevel modeling analyses indicated that suicide-specific rumination was associated with suicidal intent, above and beyond suicidal ideation, perceived burdensomeness, thwarted belongingness, agitation, insomnia, nightmares, and sociodemographic characteristics. Further, a lagged model demonstrated that suicide-specific rumination predicted subsequent time-point suicidal intent, controlling for current suicidal intent and all other covariates. Overall, these findings suggest that perseverating on one's suicidal thoughts may serve as a proximal factor that increases suicide risk. Future investigations should explore potential mechanisms of this association, as well as interventions that may reduce suicide-specific rumination.

A Preliminary Investigation Into a Range of Implicit and Explicit Offense Supportive Cognitions in Perpetrators of Physical Intimate Partner Violence

The current study assessed a wide range of offense supportive cognitions in relation to the perpetration of physical intimate partner violence (IPV). This research used both implicit and explicit measures in a U.K. sample of 19 male IPV perpetrators recruited from a community-based IPV intervention program and 20 men from the community with no history of IPV. The study also explored the ability of the implicit measures to differentiate between the two groups. The cognitions assessed included gender-role stereotype, attitudes condoning violence against a partner, attitudes condoning violence in general, hostile attitudes toward women, sense of entitlement in the relationship and over the intimate partner (control and dominance), and general sense of entitlement. Participants completed a number of established self-report measures and a series of computer-based reaction time tasks including two implicit association tests, one go/no-go association task, and four sentence judgment tasks. Significant group differences emerged across all measures both at the explicit and at the implicit level. Most implicit measures had very good discriminatory power, and the combination of all implicit measures showed excellent discriminatory power, equal to that of the explicit measures combined. These findings suggest that some IPV perpetrators hold offense supportive cognitions that may have become fairly well established and have started to operate at an automatic level. Implicit measures could be useful tools for risk assessment purposes and identification of treatment needs alongside already established measures.

New Methods for Assessing Rapid Changes in Suicide Risk

Rapid-acting interventions for the suicide crisis have the potential to transform treatment. In addition, recent innovations in suicide research methods may similarly expand our understanding of the psychological and neurobiological correlates of suicidal thoughts and behaviors. This review discusses the limitations and challenges associated with current methods of suicide risk assessment and presents new techniques currently being developed to measure rapid changes in suicidal thoughts and behavior. These novel assessment strategies include ecological momentary assessment, digital phenotyping, cognitive and implicit bias metrics, and neuroimaging paradigms and analysis methodologies to identify neural circuits associated with suicide risk. This review is intended to both describe the current state of our ability to assess rapid changes in suicide risk as well as to explore future directions for clinical, neurobiological, and computational markers research in suicide-focused clinical trials.

Implicit measure of suicidal ideation in patients with depression

The death/suicide implicit association test (IAT) may be more resilient to accurately assess suicide risk than self-reports. We examined the IAT in 130 patients with depression and 125 healthy controls, along with self-reported suicidal ideation. IAT could differentiate patients with suicide attempts from patients without suicide attempts and controls. IAT measures were significantly correlated to explicit suicidal ideation and clinical symptoms in patients. Moreover, the IAT-symptom correlations were significant in female but not male patients. The IAT showed promise as a valid tool to estimate suicide risk in patients with depression and may be particularly useful in female patients.

Decomposing implicit associations about life and death improves our understanding of suicidal behavior

The Death/Suicide Implicit Association Test (IAT) is effective at detecting and prospectively predicting suicidal thoughts and behaviors. However, traditional IAT scoring procedures used in all prior studies (i.e., D-scores) provide an aggregate score that is inherently relative, obfuscating the separate associations (i.e., "Me = Death/Suicide," "Me = Life") that might be most relevant for understanding suicide-related implicit cognition. Here, we decompose the D-scores and validate a new analytic technique called the Decomposed D-scores ("DD-scores") that creates separate scores for each category ("Me," "Not Me") in the IAT. Across large online volunteer samples (N > 12,000), results consistently showed that a weakened association between "Me = Life" is more strongly predictive of having a history of suicidal attempts than is a stronger association between "Me = Death/Suicide." These findings replicated across three different versions of the IAT and were observed when calculated using both reaction times and error rates. However, among those who previously attempted suicide, a strengthened association between "Me = Death" is more strongly predictive of the recency of a suicide attempt. These results suggest that decomposing traditional IAT D-scores can offer new insights into the mental associations that may underlie clinical phenomena and may help to improve the prediction, and ultimately the prevention, of these clinical outcomes.

Implicit bias for suicide persists after ideation resolves

Individuals with suicidal ideation (SI), demonstrate an association between suicide-related information and the self that is automatic and outside conscious control (i.e., implicit). However, it is unclear whether this implicit bias is a state-like processes that will resolve with the reduction of SI or whether it is more trait-like and enduring. Given that implicit bias has been proposed as an indirect measurement of SI, understanding its dynamic nature is important. To investigate this, we recruited 79 (22 with a history of, but no current, SI; 57 with no lifetime history of SI) young adults who completed a structured interview assessing current and past SI. Participants also completed the Suicide Affect Misattribution Procedure assessing implicit association with suicide-relevant, negative but not suicide relevant, positive, and neutral stimuli. Participants with a history of SI demonstrated greater implicit bias for suicide compared to participants with no lifetime history, but did not significantly differ in their responses to negative, positive, or neutral stimuli. This indicates that suicide-relevant implicit bias may be a trait-like process that endures after resolution of SI. This has important implications for the conceptualization of cognitive bias in suicide and the use of these biases as implicit markers of SI.

Functional Imaging of the Implicit Association of the Self With Life and Death

OBJECTIVE

A critical need exists to identify objective markers of suicide ideation. One potential suicide risk marker is the Suicide Implicit Association Task (S-IAT), a behavioral task that uses differential reaction times to compare the implicit association between the self and death to the implicit association between the self and life. Individuals with a stronger association between the self and death on the S-IAT are more likely to attempt suicide in the future. To better understand the neural underpinnings of the implicit association between self and either life or death, a functional magnetic resonance imaging (fMRI) version of the S-IAT was adapted and piloted in healthy volunteers.

METHOD

An fMRI version of the S-IAT was administered to 28 healthy volunteers (ages 18-65, 14F/14M).

RESULTS

Behavioral results were comparable to those seen in non-scanner versions of the task. The task was associated with patterns of neural activation in areas relevant to emotional processing, specifically the insula and right ventrolateral prefrontal cortex.

CONCLUSIONS

Performance on the S-IAT fMRI task may reflect scores obtained outside of the scanner. In future evaluations, this task could help assess whether individuals at increased risk of suicide display a different pattern of neural activation in response to self/death and self/life stimuli.

The psychological scars of suicide: Accounting for how risk for suicidal behavior is heightened by its past occurrence

Not only is suicidal behavior strongly predicted by its past occurrence, but the risk for recurrence appears to increase with each subsequent attempt. The current paper discusses a potential explanation for this phenomenon, that suicide attempts may leave a residual psychological scar that heightens risk for future attempts. This possibility is evaluated against two alternatives: (i) risk for first and subsequent suicide attempts is accounted for by a shared diathesis pre-existing the first lifetime attempt, and (ii) different rates of developmental decline in risk factors account for differences in prospective number of attempts. In this discussion, a formalized conceptual framework of psychological scarring is presented, along with considerations of particular relevance to its study. Finally, the clinical implications of determining the processes underlying the association between suicide attempts and heightened risk for recurrence are discussed.

Implicit Identification with Death Predicts Suicidal Thoughts and Behaviors in Adolescents

Prior research indicates that adults' implicit identification with death can be used to predict suicidal thoughts and behaviors (STBs) in the community. However, no studies have examined whether this effect is found among adolescents-a group for whom suicide is the 2nd leading cause of death. The current study tested the utility of implicit identification with death, using a Death Implicit Association Test (IAT), for detecting and predicting STBs in adolescents. Participants were 141 adolescents 12-19 years of age (81.6% female, 74.5% White) with a current psychiatric disorder and/or currently receiving outpatient psychiatric treatment. All participants completed the Death IAT and self-report measures of STBs at baseline, as well as self-report measures of STBs at 6-month and 1-year follow-ups. At baseline, stronger implicit identification with death (higher Death IAT score) was related to greater suicide ideation (SI) frequency, severity, and duration, but did not differ based on suicide attempt history. Prospectively, higher Death IAT scores predicted any occurrence (but not frequency) of SI over the subsequent year, but not when controlling for prior SI. Death IAT scores were higher among adolescents with prior attempts who reattempted suicide over the follow-up. Examination of stimuli-level results suggested that Death IAT differences may be driven by responses on trials with specific words, including suicide and die. Implicit identification with death may be a useful behavioral indicator of suicide risk in adolescents. Preliminary findings suggest that the Death IAT may aid in predicting STBs among youth receiving outpatient treatment.

Implicit identification with death predicts change in suicide ideation during psychiatric treatment in adolescents

BACKGROUND

Suicidal thoughts and behaviors are major public health concerns in youth. Unfortunately, knowledge of reliable predictors of suicide risk in adolescents is limited. Promising research using a death stimuli version of the Implicit Association Test (Death IAT) indicates that stronger identification with death differs between adults with and without a history of suicidal thoughts and behaviors and uniquely predicts suicide ideation and behavior. However, research in adolescents is lacking and existing findings have been mixed. This study extends previous research by testing whether implicit identification with death predicts changes in suicide ideation during psychiatric treatment in adolescents.

METHODS

Participants included 276 adolescents, ages 13-19, admitted to a short-term residential treatment program. At hospital admission and discharge, adolescents completed the Death IAT and measures of recent suicidal thoughts.

RESULTS

At admission, implicit identification with death was associated with recent suicide ideation, but did not differ between those who engaged in prior suicidal behavior and those who did not. Prospectively, adolescents' implicit identification with death at admission significantly predicted their suicide ideation severity at discharge, above and beyond explicit suicide ideation. However, this effect only was significant for adolescents with longer treatment stays (i.e., more than 13 days).

CONCLUSIONS

Implicit identification with death predicts suicidal thinking among adolescents in psychiatric treatment. Findings clarify over what period of time implicit cognition about death may predict suicide risk in adolescents.

Recognizing and addressing unique vulnerabilities of suicidal patients: Suicide research at The Menninger Clinic

Suicide risk is an inescapable presence in the treatment of people with psychiatric disorders, a fact that applies especially in inpatient psychiatric settings. This article summarizes a several-year research initiative at The Menninger Clinic aimed at better understanding psychological contributors to suicidality and developing more effective clinical interventions. Two areas of research are described, an outcomes arm focused on assessing the feasibility and effectiveness of a suicide-specific intervention (The Collaborative Assessment and Management of Suicidality) and an exploratory arm whose objective is to learn about psychological vulnerabilities that distinguish suicidal from nonsuicidal patients, with an eye toward developing interventions that address such vulnerabilities. The author concludes that, combined with other developments in the field, this body of work strongly supports the view that suicidal patients should be treated with interventions that specifically target vulnerabilities that seem to set the stage for suicidal episodes.

A controlled comparison trial of the Collaborative Assessment and Management of Suicidality (CAMS) in an inpatient setting: Outcomes at discharge and six-month follow-up

This controlled comparison trial evaluated a suicide-specific intervention, the Collaborative Assessment and Management of Suicidality (CAMS), in an extended-stay psychiatric inpatient setting. Multiple outcomes were examined for 104 patients, half of whom received individual therapy from therapists trained in CAMS. The comparison group was selected from a larger pool through Propensity Score Matching to ensure comparability on age, sex, treatment program, number of prior suicide attempts, and severity of suicidal ideation. Results showed that a) all patients improved significantly across a wide range of measures, including depression, suicidal ideation, functional disability, and well-being; b) these gains were durable over a 6-month post-discharge period; and c) patients treated by a CAMS-trained individual therapist improved significantly more from admission to discharge across all measures. Differences between CAMS and non-CAMS patients were no longer statistically significant at 6-month follow-up, although statistical power was compromised due to attrition. Although replication studies are needed, these findings suggest that interventions specifically tailored for suicidal patients may have advantages compared to usual, intensive inpatient treatment, perhaps by addressing psychological vulnerabilities specific to the population. The lack of significant differences at follow-up suggest that post-treatment contact may be needed to maintain advantages associated with this and similar interventions.

Moving Beyond Self-Report: Implicit Associations about Death/Life Prospectively Predict Suicidal Behavior among Veterans

Reliance on self-report limits clinicians' ability to accurately predict suicidal behavior. In this study the predictive validity of an objective measure, the death/suicide Implicit Association Test (d/sIAT), was tested among psychiatrically hospitalized veterans. Following acute stabilization, 176 participants completed the d/sIAT and traditional suicide risk assessments. Participants had similar d/sIAT scores regardless of whether they had recently attempted suicide. However, d/sIAT scores significantly predicted suicide attempts during the 6-month follow-up above and beyond other known risk factors for suicidal behavior (OR = 1.89; 95% CI: 1.15-3.12; based on 1SD increase). The d/sIAT may augment the accuracy of suicide risk assessment.

Implicit Measures of Suicide Risk in a Military Sample

Suicide has become an issue of great concern within the U.S. military in recent years, with recent reports indicating that suicide has surpassed combat related deaths as the leading cause of death. One concern regarding suicide risk in the military is that existing self-report measures allow service members to conceal or misrepresent current suicidal ideation or suicide plans and preparations. Implicit association tests (IATs) are computer-based, reaction time measures that have been shown to be resilient to such masking of symptoms. The death/suicide implicit association test (d/s-IAT) is an empirically supported IAT that is specific to death and suicide. The present study examined whether the performance of 1,548 U.S. military service members on the d/s-IAT significantly predicted lifetime suicidal ideation and depression. Zero-inflated negative binomial regression analyses were used to test these associations. Results indicated that the d/s-IAT was neither associated with history of suicidal ideation nor history of depression.
