Alterations in performance and discriminating power of the death/suicide implicit association test across the lifespan. Psychiatry Res 2024; 335:115840. [PMID: 38492262 DOI: 10.1016/j.psychres.2024.115840] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/29/2023] [Revised: 02/02/2024] [Accepted: 03/03/2024] [Indexed: 03/18/2024]
Abstract
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.

Abstract
Obsessive-compulsive and related disorders (OCRDs) are associated with increased risk of suicidal thoughts and behaviors (STBs), yet research characterizing suicidality in OCRDs remains limited. A major challenge in assessing STBs is the reliance on explicit self-report. This study utilized multi-method assessment to examine changes in both implicit and explicit STBs in 31 adults receiving partial/residential treatment for OCRDs. Assessments were administered at admission and weekly during treatment. Approximately three-quarters of participants reported lifetime suicidal thoughts, with 16 % reporting a prior suicide attempt. OCD severity was significantly correlated with lifetime suicidal thoughts, and was significantly higher for those with lifetime suicidal thoughts and prior attempts compared to those without. Implicit biases towards death were not associated with OCD severity, and did not predict explicitly endorsed STBs. This is the first study to measure both explicit and implicit STBs in adults with OCRDs. Limitations included small sample size and lack of racial/ethnic diversity. Given the majority had recent suicidal thoughts and one in six had a prior attempt, we emphasize the importance of STB assessment in OCD treatment settings.

Abstract
Implicit self-association with death, measured by the Death/Suicide-Implicit Association Test (D/S-IAT), predicts short-term Self-Injurious Thoughts and Behaviors (SITBs) among adolescents. However, comparing the predictive utility of the D/S-IAT with explicit (i.e. self-report) self-association with life and death was not examined previously. The current study sought to examine whether the D/S-IAT and explicit self-association with life and death predict current and prospective SITBs, and to examine the association between the two measures. One-hundred and thirty-one Jewish Israeli adolescents with SITBs, aged 10-18 years (74.8% female) were assessed at clinic intake. Participants completed D/S-IAT, depression, attitudes toward life and death and suicide risk assessment at intake and one-month follow-up. Implicit, rather than explicit, attitudes toward life and death predicted SITBs at one-month follow-up, beyond depression and past SITBs. The implicit and explicit measures were not significantly related at intake, indicating that they might capture different aspects of SITBs.

Abstract
INTRODUCTION Suicide is a leading cause of death, and decades of research have identified a range of risk factors, including demographics, past self-injury and suicide attempts, and explicit suicide cognitions. More recently, implicit self-harm and suicide cognitions have been proposed as risk factors for the prospective prediction of suicidal behavior. However, most studies have examined these implicit and explicit risk factors in isolation, and little is known about their combined effects and interactions in the prediction of concurrent suicidal ideation. METHODS In an online community sample of 6855 participants, we used different machine learning techniques to evaluate the utility of measuring implicit self-harm and suicide cognitions to predict concurrent desire to self-harm or die. RESULTS Desire to self-harm was best predicted using gradient boosting, achieving 83% accuracy. However, the most important predictors were mood, explicit associations, and past suicidal thoughts and behaviors; implicit measures provided little to no gain in predictive accuracy. CONCLUSION Considering our focus on the concurrent prediction of explicit suicidal ideation, we discuss the need for future studies to assess the utility of implicit suicide cognitions in the prospective prediction of suicidal behavior using machine learning approaches.

Abstract
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.

Abstract
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.

Abstract
BACKGROUND Implicit cognitive markers may assist with the prediction of suicidality beyond clinical risk factors. The aim of this study was to investigate neural correlates associated with the Death/Suicide Implicit Association Test (DS-IAT) via event-related potentials (ERP) in suicidal adolescents. METHODS Thirty inpatient adolescents with suicidal ideations and behaviors (SIBS) and 30 healthy controls from the community were recruited. All participants underwent 64-channel electroencephalography, DS-IAT, and clinical assessments. Hierarchical generalized linear models with spatiotemporal clustering were used to identify significant ERPs associated with the behavioral outcome of DS-IAT (D scores) and group differences. RESULTS Behavioral results (D scores) showed that the adolescents with SIBS had stronger implicit associations between "death" and "self" than the healthy group (P = .02). Within adolescents with SIBS, participants with stronger implicit associations between "death" and "self" reported more difficulty in controllability of suicidal ideation in the past 2 weeks based on the Columbia-Suicide Severity Rating Scale (P = .03). For the ERP data, the D scores and N100 component over the left parieto-occipital cortex had significant correlations. Significant group differences without behavioral correlation were observed for a second N100 cluster (P = .01), P200 (P = .02), and late positive potential (5 clusters, all P ≤ .02). Exploratory predictive models combining both neurophysiological and clinical measures distinguished adolescents with SIBS from healthy adolescents. CONCLUSIONS Our results suggest that N100 may be a marker of attentional resources involved in the distinction of stimuli that are congruent or incongruent to associations between death and self. Combined clinical and ERP measures may have utility in future refinements of assessment and treatment approaches for adolescents with suicidality.

Abstract
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.

Abstract
The SARS-CoV-2 pandemic led to the rapid transition of many research studies from in-person to telephone follow-up globally. For mental health research in low-income settings, tele-follow-up raises unique safety concerns due to the potential of identifying suicide risk in participants who cannot be immediately referred to in-person care. We developed and iteratively adapted a telephone-delivered protocol designed to follow a positive suicide risk assessment (SRA) screening. We describe the development and implementation of this SRA protocol during follow-up of a cohort of adults with depression in Malawi enrolled in the Sub-Saharan Africa Regional Partnership for Mental Health Capacity Building (SHARP) randomized control trial during the COVID-19 era. We assess protocol feasibility and performance, describe challenges and lessons learned during protocol development, and discuss how this protocol may function as a model for use in other settings. Transition from in-person to telephone SRAs was feasible and identified participants with suicidal ideation (SI). Follow-up protocol monitoring indicated a 100% resolution rate of SI in cases following the SRA during this period, indicating that this was an effective strategy for monitoring SI virtually. Over 2% of participants monitored by phone screened positive for SI in the first six months of protocol implementation. Most were passive risk (73%). There were no suicides or suicide attempts during the study period. Barriers to implementation included use of a contact person for participants without personal phones, intermittent network problems, and pre-paid phone plans delaying follow-up. Delays in follow-up due to challenges with reaching contact persons, intermittent network problems, and pre-paid phone plans should be considered in future adaptations. Future directions include validation studies for use of this protocol in its existing context. This protocol was successful at identifying suicide risk levels and providing research assistants and participants with structured follow-up and referral plans. The protocol can serve as a model for virtual SRA development and is currently being adapted for use in other contexts.

Abstract
Suicide screening is critical in pediatric emergency departments (EDs). Behavioral measures of suicide risk may complement self-report measures. The current study examines suicide-specific behavioral measures and tests their potential short-term within-person effects among respondents, ability to discriminate future suicide attempt from suicidal ideation, and translation into interpretable categorical composite scores. The sample included 167 youth (10-17 years), presenting for suicide-related reasons to a pediatric psychiatric ED. During their ED visit, participants completed the Death/Life Implicit Association Test (IAT) and the Suicide Stroop Task. Recurrent suicidal thoughts and attempts were assessed within 6 months of the ED visit via medical records and email surveys. Youth displayed a decrease in the levels of distress and self-injurious desires (negative mood, desire to hurt themselves, and desire to die) after completing the behavioral tasks. The Death/Life IAT prospectively differentiated with 68% accuracy between youth who attempted suicide after their ED visit and those who had suicidal ideation but no attempt, p = 0.04, OR = 5.65, although this effect became marginally significant after controlling for self-report and demographic covariates. Neither the Suicide Stroop Task, nor the categorical composite scores predicted suicide attempts, ps = 0.08-0.87, ORs = 0.96-3.95. Behavioral measures of suicide risk administered in the ED do not appear to increase distress or self-injurious desires. They may be able to distinguish those who go on to attempt suicide (vs. consider suicide) within six months after discharge.

Abstract
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.

Abstract
OBJECTIVE Nonsuicidal self-injury (NSSI) is a robust predictor of suicide ideation and attempts, but it is not clear how and why this connection is so strong. Using the Integrated Motivational-Volitional Model of suicide as a framework, select features of NSSI were examined as motivational moderators between hopelessness and suicide ideation. METHOD Data were collected from 420 emerging adults (mean age = 18.9; 84% female, 92% white), all of whom had past-year NSSI. Participants completed self-report measures that assessed NSSI and suicide history, effectiveness of NSSI in achieving functions, and hopelessness; they also completed the self-injury Implicit Association Test (IAT). RESULTS Moderation analyses revealed that none of the interactions were significant. Additional analyses tested unconditional effects of all predictor variables and found hopelessness, self-rated future likelihood of engaging in NSSI, effectiveness of NSSI in achieving intrapersonal functions, and self-injury IAT scores were each significantly associated with suicide ideation. CONCLUSIONS These results reinforce the important role of hopelessness, perceived effectiveness of NSSI in achieving intrapersonal functions, acknowledgement of future NSSI, and self-identification with NSSI as potential indicators of increased suicide risk, while also emphasizing further study of other possible moderating factors.HIGHLIGHTSFeatures of NSSI did not moderate the hopelessness-suicide ideation relationship.Features of NSSI did associate with increased suicide ideation frequency.Future likelihood of, implicit association with, and intrapersonal effectiveness of NSSI were important.

Abstract
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.

Abstract
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.

Abstract
Objective This study aimed to test the psychometric properties of the suicide stroop task in a Chinese college population. Methods College students (n = 121) who were in the 1st–4th grade, fluent in Chinese, and without color blindness were recruited from a university in Guangzhou, China from September to December 2019. Participants were administered the suicide stroop task at baseline and 1-month follow-up. Results The suicide stroop task showed excellent internal reliability (Cronbach’s α ranged from 0.940 to 0.953). However, the suicide stroop task did not reveal suicide-related attentional biases among current suicide ideators and was not significantly associated with the severity of suicidal ideation, depression, hopelessness, nor anhedonia (all p values > 0.05), indicating a lack of concurrent validity for the task. Additionally, the two-time data of interference scores could not generate intraclass correlation coefficients (ICCs) due to a negative average covariance among data, which indicated poor test–retest consistency for the task. Conclusion The results of this study did not support the use of the suicide stroop task on the identification of suicidal risk among Chinese college students. It is crucial to assess the psychometric properties of behavioral measures rigorously as self-report measures before large applications in clinical and community settings.

Abstract
In a prior publication, I used structural equation modeling of multimethod data to examine the construct validity of Implicit Association Tests. The results showed no evidence that IATs measure implicit constructs (e.g., implicit self-esteem, implicit racial bias). This critique of IATs elicited several responses by implicit social-cognition researchers, who tried to defend the validity and usefulness of IATs. I carefully examine these arguments and show that they lack validity. IAT proponents consistently ignore or misrepresent facts that challenge the validity of IATs as measures of individual differences in implicit cognitions. One response suggests that IATs can be useful even if they merely measure the same constructs as self-report measures, but I find no support for the claim that IATs have practically significant incremental predictive validity. In conclusions, IATs are widely used without psychometric evidence of construct or predictive validity.

Abstract
Individuals with autism are at heightened risk for experiencing suicidality compared to those without autism. Despite this, it is unknown what tools are used to assess suicide risk in research and clinical practice among children and youth with autism. This systematic review examined tools commonly used to measure suicidality in children and youth with and without autism spectrum disorder. Four databases were searched. We identified five tools (C-SSRS, PSS, SITBI, SIQ-JR, BSS) commonly used with youth in the general population; however, we did not identify any tools that were commonly used autistic children and youth. Results highlight the lack of available tools utilized to measure suicidality in autistic children and youth. We propose a framework to facilitate research to fill this gap.

Abstract
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.

Abstract
This article provides an overview of the study protocol for the Teen Inflammation Glutamate Emotion Research (TIGER) project, a longitudinal study in which we plan to recruit 60 depressed adolescents (ages 13–18 years) and 30 psychiatrically healthy controls in order to examine the inflammatory and glutamatergic pathways that contribute to the recurrence of depression in adolescents. TIGER is the first study to examine the effects of peripheral inflammation on neurodevelopmental trajectories by assessing changes in cortical glutamate in depressed adolescents. Here, we describe the scientific rationale, design, and methods for the TIGER project. This article is intended to serve as an introduction to this project and to provide details for investigators who may be seeking to replicate or extend these methods for other related research endeavors.

Abstract
Much of human thought, feeling, and behavior unfolds automatically. Indirect measures of cognition capture such processes by observing responding under corresponding conditions (e.g., lack of intention or control). The Implicit Association Test (IAT) is one such measure. The IAT indexes the strength of association between categories such as “planes” and “trains” and attributes such as “fast” and “slow” by comparing response latencies across two sorting tasks (planes–fast/trains–slow vs. trains–fast/planes–slow). Relying on a reanalysis of multitrait–multimethod (MTMM) studies, Schimmack (this issue, p. 396) argues that the IAT and direct measures of cognition, for example, Likert scales, can serve as indicators of the same latent construct, thereby purportedly undermining the validity of the IAT as a measure of individual differences in automatic cognition. Here we note the compatibility of Schimmack’s empirical findings with a range of existing theoretical perspectives and the importance of considering evidence beyond MTMM approaches to establishing construct validity. Depending on the nature of the study, different standards of validity may apply to each use of the IAT; however, the evidence presented by Schimmack is easily reconcilable with the potential of the IAT to serve as a valid measure of automatic processes in human cognition, including in individual-difference contexts.
