Suicide and Life-Threatening Behavior最新文献

Background: Substance use treatment programs are ideal places for suicide prevention interventions. People who misuse substances are at elevated risk for suicide compared to the general population. However, most treatment programs do not incorporate suicide prevention, and none have been adapted for American Indian and Alaska Native (AI/AN) people. Preventing Addiction Related Suicide (PARS) is a suicide prevention module developed for use with people in treatment for substance misuse. A previous study demonstrated increased suicide help-seeking among this population.

Objective: Culturally adapt PARS for use with AI/AN communities.

Methods: We conducted focus groups and interviews with stakeholders in three Tribal health systems. We elicited feedback on PARS content, structure, and implementation. Data were analyzed using constant comparison. Results were used to adapt PARS and member checking was used to refine it.

Results: Participants unanimously endorsed using PARS in their health systems. Suggested adaptations included shortening the module, using community-specific information, removing jargon and stigmatizing language, and emphasizing cultural connectedness.

Discussion: This community-based, qualitative study adapted the PARS module for use with AI/AN communities. Research is needed to evaluate the clinical effectiveness of the adapted module. If found effective, this would represent the first evidence-based suicide prevention intervention among AI/AN individuals in treatment for substance misuse.

Background: Insomnia is common in schizophrenia and associated with suicide. Clozapine has anti-suicidal properties and beneficial effects on sleep. Whether effects on insomnia mediate the anti-suicidal properties of clozapine remains unclear.

Methods: In n = 76 patients from the Clinical Antipsychotic Trials of intervention effectiveness schizophrenia trial using a within-subjects design, we investigated whether improvement in terminal insomnia was associated with improvement in suicidal ideation (SI) after treatment with non-clozapine antipsychotics, and then after treatment with clozapine, using binary logistic regression. Terminal insomnia and SI over the past 2 weeks were assessed before and after both non-clozapine antipsychotic and clozapine treatment with the Calgary Depression Scale for Schizophrenia.

Results: There was no association between improved terminal insomnia and resolution of SI after treatment with non-clozapine antipsychotics (OR = 0.2, 95% CI 0.0-9.0, p = 0.41). In the same patients, improved terminal insomnia was associated with resolution of SI after clozapine treatment (OR = 14.6, 95% CI 1.7-129.2, p = 0.02).

Conclusions: Improved terminal insomnia is associated with improved SI following clozapine treatment. Findings warrant replication in a larger sample with standard instruments in the assessment of insomnia and suicide, but suggest beneficial effects on sleep as a mediator of the anti-suicidal properties of clozapine. Future mechanistic studies are also needed.

Introduction: As suicide remains a global public health concern, recent work has sought to characterize mechanisms underlying the transition from suicidal ideation to action. Acquired capability for suicide, or fearlessness about death, has been identified as one key factor underlying this transition; however, understanding how this capability emerges remains limited. This study sought to extend previous work on the correlates of fearlessness about death by examining its relationship with painful and provocative events and emotional reactivity.

Methods: We tested the extent to which trait emotional reactivity and past self-injurious behavior moderated the relationship between assaultive trauma exposure and fearlessness about death in a diverse sample of 273 community adults (aged 18-55, M/SD = 32.77/10.78).

Results: A three-way interaction emerged, such that among individuals with heightened emotional reactivity and a history of self-injurious behavior (suicide attempt or non-suicidal self-injury), assaultive trauma was associated with increased fearlessness about death. In contrast, among adults with low emotional reactivity and a history of self-injurious behavior, assaultive trauma was associated with reduced fearlessness about death.

Conclusions: Results suggest that emotional reactivity may be a key dispositional factor that influences how trauma exposure and self-injurious behavior impact fearlessness about death.

Introduction: Previous research has identified a variety of barriers to mental health care among military personnel and veterans, despite high rates of mental health symptoms. The current study is the first to examine beliefs about mental health treatment barriers among post-9/11 military personnel and veterans at elevated suicide risk not involved in treatment and whether these beliefs are associated with treatment initiation, engagement, or suicidal behaviors.

Methods: Four hundred and twenty-two participants reported on beliefs about treatment during a cognitive behavioral treatment session and responded to follow-up questionnaires on mental health treatment initiation, engagement, and suicidal behaviors over 12 months. Beliefs identified in the therapy session were coded thematically, and rates of treatment initiation, engagement, and suicidal behavior were examined by belief category.

Results: Nine belief themes emerged. Participants reporting logistical barriers and preferences about treatment type were least likely to initiate mental health treatment and participated in the fewest number of sessions, respectively. Participants endorsing beliefs about stigma or using other ways to cope were most likely to engage in suicidal behavior.

Conclusions: The current findings point to specific beliefs that may identify individuals who would benefit from systemic and individual interventions for mental health treatment engagement.

Introduction: Suicidal ambivalence is a recognized phenomenon in suicidology, yet not much is known about it in the context of progression from suicidal ideation to action. The current study addresses this gap. We explore narrative dynamics of suicidal ambivalence in stories about transition from suicidal ideation to action.

Methods: We employ an experiential qualitative approach to gain in-depth understanding of narrated experience of suicidal ambivalence. We conducted semi-structured interviews with 22 patients hospitalized after a suicide attempt. For a detailed analysis, we selected 11 interviews in which the interviewees' accounts spontaneously referred to their ambivalence about attempting suicide. We used a text-oriented version of Critical Discourse Studies (CDS) to analyze the semantics and syntax, as well as the functions of what was said within the local context, and the social actions thus accomplished.

Results: Our study shows primarily that ambivalence is not resolved. Rather, it is set aside and removed from the narrative and replaced by an action-focused narrative with no references to mental activities.

Conclusion: We propose that ambivalence recedes and gives way to action and that qualitative research provides a useful evidence base for conceptualizing and understanding the role of ambivalence in transition from suicidal ideation to action.

Introduction: Suicidal ambivalence is increasingly understood as the result of the interplay of two conflicting motivational orientations, the wish to die (WTD) and wish to live (WTL). However, research is scarce regarding the nature of their relationship, their temporal structure, and their relevance in predicting suicidal desire.

Methods: Fifty psychosomatic/psychiatric inpatients (17 reporting suicide attempts) took part in an intensive longitudinal design with 10 signal-contingent prompts per day over 10 days; assessing WTD, WTL, and suicidal desire. We calculated mean values and variability of WTD, WTL, suicidal ambivalence, and suicidal desire and tested mixed-effects models of suicidal desire.

Results: The mean number of answered prompts was 40.98 (SD = 21.68). Repeated-measures correlation of WTD and WTL was r = -0.60. Patients with a history of suicide attempts reported higher WTD, lower WTL, more suicidal ambivalence, stronger suicidal desire, and showed higher variability in all constructs. At the same assessment, WTD was the strongest statistical predictor of suicidal desire. Only WTL and the interaction of WTD and WTL predicted suicidal desire prospectively.

Conclusion: Wish to die and WTL are likely two distinct (although correlated) constructs that should not be reduced to a single ambivalence score. A stronger focus on WTL holds potential for suicide research and practice.

Background: Suicidal ambivalence is considered a characteristic condition of suicidal individuals. At the same time, there is a lack of a uniform definition, conception and assessment of suicidal ambivalence. On this background, the current scoping review aims to explore the extent, range, and nature of research activity on suicidal ambivalence and to summarize research findings.

Methods: A systematic literature search was conducted in four different databases (PubMed, Psychinfo, Web of Science, and Google Scholar) using an array of search terms (e.g., ambivalence, internal suicide debate, reasons for living and reasons for dying, wish to live and wish to die).

Results: In total, 28 articles published between 1977 and 2023 were included in the scoping review. The study situation lacks a clear definition, conceptualization and operationalization of suicidal ambivalence. Nonetheless, suicidal ambivalence is a common experience in persons contemplating suicide and suicidal ambivalence seems to be present before, during and after a suicide attempt. Suicidal ambivalence is associated with diverse markers of negative/positive mental health as well as suicidal ideation and behavior.

Conclusion: Results point to the relevance of suicidal ambivalence. At the same time, there are large gaps in knowledge about the development, impact and therapeutic responsiveness of suicidal ambivalence.

Objective: Suicide risk is highly fluctuating. There is a need for predictors of short-term change in suicide risk to optimize risk assessment and treatment, especially among individuals who already attempted suicide.

Methods: Based on 1776 daily assessments of 16 former psychiatric inpatients with a history of suicide attempts, we examined how suicidal ambivalence and, respectively, wish to die (WTD) and wish to live (WTL) predicted same-day and change in perceived suicide risk (i.e., next-day perceived suicide risk, controlled for same-day perceived suicide risk) in multilevel regression models. Additionally, based on the assumptions of nonlinear dynamics, we examined the associations between levels of fluctuations in the WTD/WTL and perceived suicide risk within the same time period.

Results: Suicidal ambivalence, WTD, and a WTL significantly correlated with same-day suicide risk. Suicidal ambivalence and WTD significantly predicted change in suicide risk. Fluctuations in WTD were significantly associated with concurrent suicide risk.

Conclusion: The results suggest that suicidal ambivalence and WTD are drivers of suicide risk among individuals who already attempted suicide. The association between fluctuations in WTD and suicide risk was small and warrants further investigation on the practical utility as a warning sign.

Introduction: Research has largely conceptualized suicidal ambivalence as the difference between one's wish to live and wish to die without fully considering other suicide ideation (SI) experiences included on measures like the Beck Scale for Suicide Ideation (BSS). We utilized BSS items to identify SI latent classes and examined relevant correlates and outcomes.

Methods: We collected self-report data from two samples of US adults who: (1) self-identified as LGBTQ+ (N = 349; cross-sectional) and (2) self-reported past-week SI (BSS score ≥ 11; N = 133; 3 timepoints).

Results: Latent class analyses supported three-class (Sample 1) and four-class solutions (Sample 2), which included ambivalent classes. In Sample 1, sexual orientation, gender, depression, anxiety, SI, and suicide-specific rumination were concurrently associated with class membership. In Sample 2, depression, SI, suicide-specific rumination, and physical/psychological distance from suicide methods were concurrently associated with class membership. In Sample 2, at both follow-ups, suicide plans/preparations and Acute Suicidal Affective Disturbance symptom frequencies were provided by class membership, and suicidal intent significantly differed by class membership.

Conclusions: SI classes differed by sample and evidenced nuances in SI and suicidal ambivalence. Risk factors and suicide-related outcomes also differed by class membership. Implications and limitations are discussed.

Background: Ambivalence in attitudes towards life and death are associated with suicide ideation (SI) among adolescents. However, previous research was mainly cross-sectional and did not examine through which psychopathological mechanisms (such as depression) attitudes towards life and death are associated with SI.

Objective: The current longitudinal study examined the mediating role of depression at follow-up in the association between attitudes towards life and death at baseline and SI at follow-up among at-risk adolescents referred to an outpatient psychiatric clinic.

Methods: 129 adolescents aged 10-18 years (75.2% females) with a history of suicidal thoughts and behaviors were assessed at clinic intake and 1 month follow-up (80% retention rate at follow-up). All participants completed a questionnaire assessing attitudes towards life and death and SI severity at clinic intake, and depression and SI severity at 1 month follow-up.

Results: While controlling for SI severity at intake, attraction towards life at baseline, rather than attraction and repulsion towards death at baseline, led to higher SI severity at follow-up, while depression at follow-up fully mediated this association.

Conclusions: Attitudes towards life, as well as depression play critical roles in the development of SI among adolescents. Interventions targeting reasons for living and promoting meaning of life may be beneficial in preventing depression and SI.
