Suicide and Life-Threatening Behavior最新文献

Background: This study addresses the suicide risk predicting challenge by exploring the predictive ability of machine learning (ML) models integrated with theory-driven psychological risk factors in real-time crisis hotline chats. More importantly, we aimed to understand the specific theory-driven factors contributing to the ML prediction of suicide risk.

Method: The dataset consisted of 17,654 crisis hotline chat sessions classified dichotomously as suicidal or not. We created a suicide risk factors-based lexicon (SRF), which encompasses language representations of key risk factors derived from the main suicide theories. The ML model (Suicide Risk-Bert; SR-BERT) was trained using natural language processing techniques incorporating the SRF lexicon.

Results: The results showed that SR-BERT outperformed the other models. Logistic regression analysis identified several theory-driven risk factors significantly associated with suicide risk, the prominent ones were hopelessness, history of suicide, self-harm, and thwarted belongingness.

Limitations: The lexicon is limited in its ability to fully encompass all theoretical concepts related to suicide risk, nor to all the language expressions of each concept. The classification of chats was determined by trained but non-professionals in metal health.

Conclusion: This study highlights the potential of how ML models combined with theory-driven knowledge can improve suicide risk prediction. Our study underscores the importance of hopelessness and thwarted belongingness in suicide risk and thus their role in suicide prevention and intervention.

Background: The objective of this systematic review is to describe the scientific evidence for the Suicide Crisis Syndrome (SCS), a presuicidal cognitive and affective state consisting of five symptomatic dimensions: entrapment, affective disturbance, loss of cognitive control, hyperarousal, and social withdrawal. The aim of this article is to summarize the emerging literature on the SCS and to assess the extent to which a uniform syndrome can be assumed.

Methods: A systematic literature search was conducted in three different databases (PubMed, PsycInfo, and Google Scholar) using the search terms "Suicide Crisis Inventory," "Suicide Crisis Syndrome," "Narrative Crisis Model of Suicide," and "Suicide Trigger State."

Results: In total, 37 articles from 2010 to 2022 were identified by search criteria. Twenty-one articles published between 2017 and 2022 were included in the systematic review. All but three studies were conducted in the United States and examined clinical samples of adult high-risk psychiatric in- and outpatients. Sample sizes ranged from N = 170 to 4846. The findings confirm the unidimensional structure of the proposed disorder and support the predictive validity for short-term suicidal behavior above and beyond suicidal ideation.

Conclusion: Despite the promising predictive validity of the SCS, a precise prediction of future suicidal behavior remains difficult.

Introduction: Religion is a salient aspect of patient background in treatment (The psychology of religion and coping: Theory, research, practice; Guilford Press). However, research investigating the role of religion in suicide is lacking and inconsistent (Journal of Religion and Health, 57, 2478-2499). The current study (1) clarifies the association between religious identity and fearlessness about death in a psychiatric sample and (2) tests whether religious identity moderates the association between fearlessness about death and suicidal ideation.

Methods: Participants were 155 patients seeking treatment in a partial hospital program. Religious identity was assessed using the Identities in Treatment Scale (The Behavior Therapist). Fearlessness about death was assessed with two relevant items from the acquired capability with rehearsal for suicide scale (Psychological Assessment, 28, 1452-1464), as in prior studies (Suicide & Le-Threatening Behavior, 50, 1230-1240; Journal of Affective Disorders Reports, 12, 100492).

Results: Fearlessness about death interacted with religious identity to predict suicidal ideation, b = 0.47, 95% C.I. [0.02, 0.91], p = 0.042. Conditional effects showed that greater fearlessness about death was associated with greater suicidal ideation among non-religious patients, b = -0.56, 95% C.I. [-0.88, -0.24], p = 0.001, but not in religious patients, b = -0.09, 95% C.I. [-0.41, 0.22], p = 0.559.

Conclusions: Our results suggest that fearlessness about death is a risk factor for suicidal ideation, but only among those who do not identify as religious. Results from this study inform theories of suicide and elucidate the influence of religious identity on links among suicide risk factors and suicide-related outcomes.

Introduction: Aspects of social relationships have variably been associated with suicidal ideation (SI) and suicide attempts (SAs). This study assessed whether social support and social distress measures have general factors versus measure-specific factors that are associated with suicide risk.

Methods: Adults (N = 455, 60.0% female), admitted to psychiatric inpatient units following a recent suicide attempt or active SI, completed assessments of social support (emotional support, instrumental support, friendship, perceived support from significant others, friends, family) and social distress (loneliness, perceived rejection, perceived burdensomeness, thwarted belongingness). Bifactor modeling examined general and specific factors of social support and distress in relation to SI (week prior to hospitalization, via the Beck Scale for SI) and SAs (past 30 days, via the Columbia Suicide Severity Rating Scale).

Results: SI was significantly associated with the general social support (B = -1.51), the general social distress (B = 1.67), and the specific perceived burdensomeness (B = 1.57) factors. SAs were significantly associated with the specific Perceived Rejection (OR = 1.05) and Thwarted Belongingness (OR = 0.91) factors.

Conclusion: General social support and social distress were associated with SI but not recent SAs. Specific social distress factors were also related to SI and SAs controlling for general social distress, suggesting areas for future interventions.

Introduction: Anxiety and suicidal ideation have been shown to be positively related in adolescents. However, less is known about the strength of this association across different types of anxiety or the mechanisms through which this relation exists. Joiner's interpersonal theory of suicide suggests that thwarted belongingness (TB) and perceived burdensomeness (PB) lead to suicidal ideation; these constructs may explain a pathway through which anxiety and suicidal ideation are related. It was hypothesized that TB would mediate the relation between social anxiety disorder (SAD) symptoms and suicidal ideation, and PB would mediate the relation between generalized anxiety disorder (GAD) symptoms and suicidal ideation.

Methods: These longitudinal mediation models were assessed using data collected from 147 depressed adolescents, who were recently hospitalized for suicidal ideation or behavior, enrolled in a randomized controlled trial (RCT).

Results: Consistent with study hypotheses, PB mediated the relation between GAD symptoms and suicidal ideation severity. However, TB did not mediate the relation between SAD symptoms and suicidal ideation severity.

Conclusion: These results suggest that screening for and addressing PB among youth with GAD may help reduce risk for suicidal behavior.

Introduction: Sexual and gender minority (SGM) people are at increased risk for suicidal thoughts and behaviors relative to their cisgender heterosexual peers. However, most research in this area has focused on youth, limiting our understanding of suicide risk among SGM adults.

Methods: To address this gap in the literature, the present study examined suicidal thoughts and behaviors among SGM adults across different age groups using a sample of 10,620 US adults.

Results: Consistent with the literature on youth, SGM adults showed higher rates of suicidal thoughts and behaviors than cisgender heterosexual adults. When examining prevalence rates across various age groups, young adults (18-24) showed greater lifetime and past month suicidal thoughts and behaviors relative to adults ages 45+. Adults ages 18-24 also showed greater past month suicidal ideation than adults ages 25-44; however, there were no group differences in lifetime suicidal thoughts and behaviors and past month suicidal behavior between adults ages 18-24 and 25-44.

Conclusions: Although suicidal thoughts and behaviors are most common among young SGM adults, other age groups do still show concerning rates of suicidal thoughts and behaviors, suggesting that this risk might extend to later years of life. Additional resources for SGM adults that are not only tailored toward youth and young adults are warranted.

Introduction: High rates of suicidal ideation (SI), suicide attempts (SA), and repetitive nonsuicidal self-injury (NSSI) among some ethnoracially minoritized United States youth populations may be related to adverse childhood experiences (ACEs) with structural roots.

Methods: Using the 2013-2019 Minnesota Student Surveys, we assessed associations of student-reported structural ACEs (parental incarceration, housing instability, food insecurity, and foster care involvement) with SI, SA, and repetitive NSSI within the past 12 months using multilevel logistic regression stratified by ethnoracial group (American Indian/Alaskan Native [AIAN], Hmong, other Asian, Black Latino, other Latino, Somali, other Black/African American [AA], Native Hawaiian/Pacific Islander [NHPI], and multiracial), and adjusted for sex, grade, ACEs experienced within one's household, mental health treatment, and perceived safety.

Results: Structural ACEs were strongly associated with increasing SI, SA, and NSSI. At ≥2 structural ACEs, repetitive NSSI rates ranged from 7% to 29% (female), 8% to 20% (male); SA rates ranged from 13% to 35% (female), 10% to 22% (male); and SI rates ranged from 31% to 50% (female), 20% to 32% (male). Black Latino, NHPI, AIAN, and Black/AA students most often reported structural ACE exposures.

Conclusion: Reducing structural ACEs may reduce SI, SA, and repetitive NSSI among ethnoracially minoritized youth populations. Disaggregating diverse youth groups revealed variations in these outcomes that remain hidden when subpopulations are aggregated.

Introduction: Mentalization-based therapy (MBT) and its adapted version for adolescents (MBT-A) are repeatedly highlighted as promising treatments for reducing self-harm, particularly in borderline personality disorder (BPD). Despite the availability of publications providing evidence of their efficacy in reducing self-harm, recent meta-analyses have yielded mixed results. To inform best-practice clinical decision-making, we conducted a systematic review and meta-analysis. We aimed to disentangle findings for both adolescents and adults on the efficacy of MBT(-A) in reducing self-harm (primary outcome) and symptoms of BPD and depression (secondary outcomes).

Methods: Web of Science, Scopus, Embase, PubMed/Medline, and Cochrane Review Database were searched for eligible studies published until September 2022. In total, 14 studies were identified, comprising 612 participants from nine MBT studies (six pre-post, three RCTs) and five MBT-A studies (two pre-post, three RCTs). Aggregated effect sizes were estimated using random-effects models. Meta-regressions were conducted to assess the effect of moderator variables (treatment duration, drop-out rates, and age) on effect sizes.

Results: Overall, both MBT and MBT-A demonstrated promising effects in reducing self-harm (g = -0.82, 95% CI -1.15 to -0.50), borderline personality disorder (g = -1.08, 95% CI -1.38 to -0.77), and depression (g = -1.1, 95% CI -1.52 to -0.68) symptoms. However, when compared to control interventions (TAU, SCM), MBT(-A) did not prove to be more efficacious, with the exception of MBT showing superior effects on BPD symptoms in adults (g = -0.56, 95% CI -0.88 to -0.24).

Conclusion: Although the pre-post evaluations seem promising, this analysis, including RCTs, showed no superiority of MBT(-A) to control conditions, so that prioritizing the application of MBT (-A) for the treatment of self-harm is not supported. Possible explanations and further implications are discussed.

Introduction: While negative affect and problem-solving deficits have been consistently linked to suicidal thoughts and behaviors, the latter are often conceptualized and studied as time- and/or context-invariant. Though requiring additional empirical support, theory suggests that discrimination may strengthen the relation between rejection sensitivity and increases in negative affect as well as declines in problem-solving abilities following rejection. The aim of the current study was to test this claim using a social rejection paradigm (i.e., Cyberball) with young adults experiencing past-month suicidal ideation.

Methods: The sample consisted of 50 participants. Lifetime discrimination and rejection sensitivity were assessed prior to Cyberball. Negative affect and problem-solving abilities were assessed pre- and post-Cyberball. SPSS and the PROCESS macro were used to test relations among variables of interest.

Results: Rejection sensitivity predicted greater problem-solving decrements, but not negative affect, following rejection among individuals who had experienced higher (vs. lower) levels of lifetime discrimination.

Conclusion: Addressing rejection sensitivity and sources of discrimination within the context of treatment may reduce the impact of social rejection on problem-solving abilities among young adults at risk for suicide.

Objective: One-third of all global suicide deaths occur among adolescents and young adults, making suicide the second leading cause of death among young people. Nearly 80% of suicide deaths occur in low- and middle-income countries, and many African nations have higher rates of suicide than global averages. However, interventions are scarce. We conducted a scoping review of counseling interventions for suicide prevention among youth in Africa.

Method: We performed structured searches of the Medline, Embase, PyscINFO, African Index Medicus, Global Heath Database, and Proquest Dissertations and Theses Global databases. Studies were eligible for inclusion if they described a counseling intervention conducted in Africa, focused on participants under age 22, and included a suicide-related outcome.

Results: After removal of duplicates, 1808 titles and abstracts were screened and 10 studies were identified for full-text review. Of these, six included adult participants and did not disaggregate results for youth, two did not describe an intervention, and two did not include a relevant outcome. Thus, no studies were eligible for inclusion.

Conclusions: This empty review highlights the striking absence of published research on a life-threatening public health challenge, representing a distinct call to action for improved efforts in adolescent suicide prevention in Africa.
