RESUMEN
Self-dehumanization, a phenomenon relevant to social psychology, has been somewhat absent from clinical psychology research. Furthermore, measures of self-dehumanization are few, and to our knowledge, no validated and generalizable self-report measure exists. To address this gap, we present a Self-Dehumanization Scale (SDS). This work incorporates evidence from three studies examining the reliability, validity, and factor structure of the SDS in an undergraduate sample, a clinically relevant community sample, and a sample with at least one minoritized identity. The SDS was derived from dehumanization theory and was developed to measure animalistic and mechanistic self-dehumanization. All studies suggested an 8-item SDS, with Study 1 suggesting a single-factor solution with, however, some indication of a two-factor structure, and Studies 2 and 3 affirming a two-factor solution. The SDS, and its respective factors, generally showed discriminant validity from related, yet distinct, measures of self-hate, self-esteem (Study 2), dissociation, and measures of discrimination (in Study 3). Finally, animalistic and mechanistic SDS showed somewhat mixed but promising evidence regarding their associations to minoritized identities and to symptoms of depression, and suicide risk, above and beyond each study's fairly stringent control variables. Thus, self-dehumanization may prove to be a clinically promising leverage point in assessing psychopathology, particularly among minoritized communities.
This work develops and tests a generalizable measure of self-dehumanization, perceiving oneself as nonhuman, as a tool to further understand and assess psychopathology. Findings indicate a validated scale that shares relations to minoritized identity and to symptoms of depression and suicide risk above and beyond known risk factors.
RESUMEN
Theory proposition, empirical evaluation, and resulting support or refutation are core pieces of the scientific process. These steps of theory-testing, however, can be complicated by relative rigidity and dogmatism, in combination with the logistical challenges inherent in conducting comprehensive, real-world tests of theories explicating complex scientific phenomena, especially rare ones. It may be argued that suicide is one such phenomenon, and one for which the field of psychology has struggled to develop satisfactory understanding. One leading theory of suicide, the Interpersonal Theory of Suicide, has garnered attention and, to a considerable degree, has weathered substantial scrutiny. Still, it is arguable that the theory has yet to be tested in full-that is, in accordance with all propositions originally put forth. In this effort, we sought to evaluate the current state of knowledge regarding the Interpersonal Theory of Suicide, as well as to suggest potential directions via which future work may proceed. We draw from the fields of philosophy, psychology, physics, and engineering in the hopes of engendering curiosity and critical thought about the assumptions researchers (ourselves included) bring to their work. We direct particular attention to the role of refutation in theory-testing; the supposed dichotomy of explanatory vs. algorithmic approaches; and the categorization of research programs as progressive vs. degenerative. In doing so, we hope not only to promote these ideas in the study of suicidal behavior but also to empiricists of all creeds and foci. We also include implications for suicide prevention efforts.

OBJECTIVE: Suicidal thoughts and behaviors (STBs) are a serious public health problem in the United States and of particular concern among active-duty service members and veterans. Research indicates hyperarousal, through its relevance across other disorder constructs and correlations with risk factors, may confer suicide risk in this population. Investigation of hyperarousal's connection with STBs and risk factors relevant to military mental health may be illuminating. METHOD: A network analysis was conducted to examine whether hyperarousal transdiagnostically linked STBs with psychopathology symptoms and relevant correlates (i.e., alcohol use disorder symptoms, substance abuse, insomnia, and cognitive anxiety sensitivity [AS]) in a sample of active-duty service members and veterans (N = 1,050). RESULTS: Hyperarousal shared direct associations with suicidal ideation, suicidal intent, and lifetime history of suicide attempts when examined in independence. It indirectly correlated with STBs via cognitive AS and insomnia when psychopathology symptoms and relevant correlates were included in the network. The network structure did not differ between active-duty personnel and veterans. CONCLUSIONS: Hyperarousal examined in independence may appear to directly correlate with STBs but this relationship may be better accounted for by cognitive AS and insomnia.

RESUMEN
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.

Measurement invariance across diverse groups, though crucial for determining the generalizability of a measure, has not yet been tested in many assessments of suicidal thoughts. The present study assessed the measurement invariance and psychometric properties of one such assessment, the Depressive Symptom Inventory-Suicidality Subscale, across multiple identity dimensions in a large data set (n = 1,118) that combined three diverse samples. Findings supported measurement invariance of the scale by race, ethnicity, and sexual orientation when comparing those who were majority-aligning with their minoritized counterparts, as well as good internal consistency and expected convergent validity. The expected one-factor structure fit well for all three of the samples assessed. Overall, the results support measurement invariance and generalizability of the Depressive Symptom Inventory-Suicidality Subscale. Future studies should continue assessing measures of suicidal thoughts and behaviors through testing invariance across identities, especially as it pertains to specific identity subgroups and their intersections.

BACKGROUND: Despite high rates of suicide among people with psychosis, relatively little is known about the mechanisms underlying the transition from suicidal ideation to behavior in this population. The Interpersonal Psychological Theory of Suicide (IPTS) proposes that fearlessness about death (FAD) may play a role in this relationship. The present study tested whether constructs of the IPTS [thwarted belongingness (TB), perceived burdensomeness (PB), and FAD] were associated with the severity of suicidal ideation in a sample of adults with histories of psychosis. METHOD: 261 adults with histories of psychosis completed measures of IPTS constructs, current severity of suicidal ideation, and history of suicidal attempts. We examined differences between those with past suicide attempts and those without and conducted regression analyses to evaluate the associations among TB, PB, FAD and severity of current suicidal ideation. RESULTS: Contrary to expectations, a history of suicidal behavior was not uniquely associated with FAD. Regression analyses revealed TB × PB and FAD × PB interactions emerged as significant correlates of the severity of suicidal ideation, with the relationship between PB and suicidal ideation more pronounced at higher levels of FAD and TB. Interestingly, positive symptoms of psychosis were positively associated with PB. IMPLICATIONS: This study provides support for broadening the investigation of FAD as a contributor to suicidal ideation in individuals with psychotic symptoms. Future research investigating the role of other contributors that may influence capability for suicide (e.g., impulsivity) may add additional understanding of suicide in this population.

OBJECTIVE: Acute Suicidal Affective Disturbance (ASAD) has been proposed to address the need for a suicide-specific diagnostic entity that better accounts for the psychological symptoms that may emerge during an acute suicidal crisis and that may precede imminent suicidal behaviors. However, additional research is needed to establish ASAD's delimitation from preexisting psychological disorders, especially disorders that include suicidal thoughts and behaviors in their diagnostic criteria such as borderline personality disorder (BPD). METHODS: We estimated two Gaussian graphical models (GGMs), exploratory factor analysis (EFA) models, and confirmatory factor analysis models in a sample of psychiatric outpatients (N = 460) to examine the structure of ASAD and BPD symptoms. RESULTS: Our estimated models showed while most ASAD and BPD symptoms largely shared associations with other symptoms belonging to their respective disorder construct, strong associations connected some ASAD symptoms with BPD symptoms, which, in a network model, emerged in the form of nonzero edges among those symptoms, and in EFA models, as factors that featured both ASAD and BPD symptoms as indicators. CONCLUSIONS: Our findings suggest the network structure of the proposed criteria of ASAD features symptoms that are largely distinct to ASAD but do include symptoms that share meaningful correlations with BPD symptoms that suggest ASAD and BPD are correlated constructs.

Two proposed suicide-specific diagnoses, with accumulating research support, characterize the phenomenology of acute suicidal crises: Suicide Crisis Syndrome (SCS) and Acute Suicidal Affective Disturbance (ASAD). Despite conceptual overlap and some similar criteria, the two syndromes have never been compared empirically. The present study addressed this gap by examining SCS and ASAD utilizing a network analysis approach. A sample of 1568 community-based adults (87.6% cisgender women, 90.7% White, Mage = 25.60 years, SD = 6.59) in the United States completed an online battery of self-report measures. SCS and ASAD were first examined in individual network models, followed by a combined network to determine changes in network structure, as well as identify bridge symptoms that connected SCS and ASAD. The proposed criteria of SCS and ASAD formed sparse network structures that were largely unaffected by the influence of the other syndrome in a combined network. Social disconnection/withdrawal and manifestations of overarousal-particularly agitation, insomnia, and irritability-emerged as bridge symptoms that may connect SCS and ASAD. Our findings indicate the network structures of SCS and ASAD exhibit patterns of independence, alongside interdependence between overlapping symptom domains (i.e., social withdrawal, overarousal). Future work should examine SCS and ASAD prospectively to better understand their temporal dynamics and predictive utility in relation to imminent suicide risk.

Recent work has identified fearlessness about suicide, rather than fearlessness about death, as more theoretically relevant in the assessment of capability for suicide and thus a more appropriate construct of measurement. The aim of the current project was to develop and validate a scale specifically assessing fearlessness about suicide. Across two studies, support for a 7-item, single-factor structure of the Fearlessness About Suicide Scale (FSS) emerged. The FSS factor structure demonstrated a good fit in the first study and was replicated in the second study. Measurement invariance was examined across those identifying as men and women and found to be comparable. The FSS also demonstrated test-rest reliability and good convergent and divergent validity in community and undergraduate samples. Overall, findings indicate that the FSS has a replicable factor structure that generalizes across those identifying as men and women and may better assess components of capability for suicide than existing scales.
RESUMEN
OBJECTIVE: This study employed network analysis to characterize central autism spectrum disorder (ASD) traits and suicide symptoms within an active duty military sample as well as to identify symptoms that may bridge between ASD traits and suicidality (i.e., suicidal ideation and behaviors). METHOD: Participants were active duty U.S. military service members (N = 287). Autism spectrum traits, suicidality, depression, and suicide related constructs were assessed online via self-report. RESULTS: Within the combined ASD trait-suicidality network, suicide rumination, suicide behaviors, and depression had the highest strength centrality. The most central bridge symptoms between ASD and suicidality were thwarted belongingness, social skills deficits, and depressive symptoms. CONCLUSIONS: Social skills deficits and thwarted belongingness may function as a meaningful bridge between ASD symptoms and suicidality within active duty members. Individuals with ASD symptoms who additionally present with high levels of thwarted belongingness and/or considerable social skills deficits may be at increased risk for suicidality.HIGHLIGHTSWithin an ASD-suicidality network, social skills deficits, low belonging, and depression had the greatest bridge strength.Although low belonging emerged as a bridge symptom, perceived burdensomeness did not.Suicide rumination, suicide behaviors, and depression were the most central symptom in an ASD-suicidality network.Symptoms related to social skills deficits may connect ASD traits and suicidality.

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.
RESUMEN
OBJECTIVE: Affective states and rumination have each been linked to suicidal ideation; however, to our knowledge, no studies have examined their interactive effect in predicting suicidal ideation in the short term. The present study examined the concurrent and short-term prospective relationships between affective states, rumination, and suicidal ideation using ecological momentary assessment (EMA). METHOD: A sample of 237 community-based adults at high risk for suicide (Mage = 27.12 years, 61.6% cisgender women) responded to six EMA prompts each day for 2 weeks that assessed their momentary affective states (depression, anxiety, happiness, hopelessness, agitation, irritability), rumination, and suicidal ideation. RESULTS: Rumination moderated the relationship between concurrent affective states and suicidal ideation, at both the within-person and between-person levels. Specifically, the relations between affective states and suicidal ideation were stronger at higher levels of rumination. These interaction effects were not found when examining short-term prospective associations. CONCLUSIONS: Affective states and rumination may each confer risk for suicidal ideation in the short term, and rumination may serve as a catalyst of the link between affective states and suicidal ideation when examined concurrently. Clinical implications, limitations, and future research directions are discussed. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Suicide is a public health concern which warrants considerable attention, especially with the onset of the COVID-19 pandemic. The current study sought to examine the relationship between behavioral, psychological, and economic impacts of COVID-19 on suicidal ideation severity in a sample of 90 undergraduate students who completed a comprehensive survey on mental health in January 2020 and were re-assessed in April, June, and July of 2020. Multiple regression analyses showed that changes in experience of loneliness, loneliness due to social distancing, pandemic-related concerns, COVID contagion anxiety, and quarantining alone positively and significantly correlated with peri-pandemic suicidal ideation severity after accounting for pre-pandemic suicidal ideation and sexual orientation, while time spent talking to romantic partner and time spent talking to friends and family were negatively correlated. Findings provide insights into the psychological and behavioral effects of social distancing measures and the pandemic, but further research is needed to generalize findings.

RESUMEN
In this study, we introduce the construct of the suicidal narrative, a hypothetical personal narrative linked to imminent suicide, and explore its relationship to near-term suicidal risk and the suicide crisis syndrome (SCS). Psychiatric outpatients (N = 289) were administered the Columbia Suicide-Severity Rating Scale (C-SSRS), Suicide Crisis Inventory (SCI), and Suicide Narrative Inventory (SNI), a novel instrument combining the documented risk factors of Thwarted Belongingness, Perceived Burdensomeness, Humiliation, Social Defeat, Goal Disengagement, and Goal Reengagement. Dimensional measures of past month, lifetime, and past suicidal phenomena, incorporating ideation and behavior, were calculated from the C-SSRS. Structural equation modeling was used to explore the interaction among variables. Factor analysis of the SNI yielded two orthogonal factors, termed Interpersonal and Goal Orientation. The former factor was comprised of Perceived Burdensomeness, Social Defeat, Humiliation, and Thwarted Belongingness, the latter of Goal Disengagement and Goal Reengagement. The Interpersonal factor correlated with both SCS severity and suicidal phenomena in each time frame and the Goal Orientation factor with no other variable. As hypothesized, the proposed model was significant for the past month only. Our findings support the construct of the suicidal narrative and its function as a near-term suicidal risk factor.
