Sexual minority young adults (SM-YAs) experience high rates of interpersonal discrimination, which increases their risk of suicidal ideation. However, little is known about the mechanisms that underly this association. According to the Anxiety Buffer Disruption Theory (ABDT) exposure to interpersonal discrimination can influence the development of a negative social worldview (i.e., antagonistic perceptions of others and the future of society) leading to the onset and maintenance of suicidal ideation. We aimed to test the utility of ABDT in articulating the association between exposure to interpersonal discrimination and suicidal ideation by examining the mediating role of negative social worldview.

Suicide is the leading cause of death on the railway networks, yet little is known about the geography and socio-environmental determinants of such deaths in England.

Perseverative coping refers to the persistent use of ineffective coping strategies, including the repetition of previously abandoned approaches. No empirical studies explored the mechanisms of stress and perseverative coping influences on suicide. Drawing on the stress and coping model of suicide risk and the diathesis-stress model of suicide, this study assessed the hypothesis that perceived stress moderates the relationship between perseverative coping and suicidal thoughts/suicide attempts.

Employment pressure has emerged as a significant stressor among Chinese university students, yet the psychological mechanisms linking this pressure to suicidal ideation remain underexplored. This study investigated how expressive suppression and depressive symptoms mediate the relationship between employment pressure and suicidal ideation. Data were collected between March and June 2024. A sample of 10,839 Chinese university students completed standardized measures of employment pressure, expressive suppression, depressive symptoms, and suicidal ideation through an online survey. Path analysis revealed that employment pressure positively predicted suicidal ideation both directly and indirectly. Expressive suppression significantly mediated the relationship between employment pressure and suicidal ideation. Furthermore, expressive suppression and depressive symptoms serially mediated the association between employment pressure and suicidal ideation. These findings suggest that employment pressure maybe associated with increased suicidal ideation through pathways involving expressive suppression, which in turn may exacerbate depressive symptoms. Interventions targeting emotion regulation strategies and depressive symptoms may help mitigate the negative psychological impact of employment pressure among Chinese university students facing competitive job markets.

Insomnia and nightmares have been identified as significant predictors of suicidal ideation (SI), but the specific psychological processes underlying this relationship remain unclear. The current study aimed to examine the insomnia/nightmares-SI relationship, concerning the mediating role of defeat and entrapment according to the integrated motivational-volitional (IMV) model in the Iranian population.

Men are more likely than women to die by suicide, while women are more likely to report suicidal ideation and make suicide attempts. To understand this, it is necessary to consider the ways in which men and women are exposed to divergent pressures in gendered social roles. We reviewed the literature to identify a set of seven pathways by which masculinity may impact upon suicidality (moderation of the relationship between masculinity and suicidality by adverse life events, mediation of the relationship between masculinity and suicidality by help-seeking, social support, maladaptive coping, impulsivity, and mental health, and a protective function of positive masculine psychological characteristics on suicidality), and tested these in two samples.

Universal screening improves suicide risk detection in individuals presenting to the emergency department (ED) who are not presenting with a psychiatric chief complaint, what we refer to as incidental risk. We sought to better understand characteristics of individuals who present with incidental risk and to evaluate their suicide-related outcomes after the ED visit.

Negative affective states are known risk factors for suicidal ideation (SI). However, most research to date has used cross-sectional or longitudinal designs with long follow-up periods to understand these relationships. Thus, the current study aimed to understand how specific negative affective states may act as acute risk factors for same day SI and predict next day SI.

Assessing psychological pain is crucial for evaluating suicide risk. This study examined differences in psychological pain between patients with suicide attempts, those with suicidal ideation, clinical, and non-clinical controls using a newly translated German version of the (MBPPAS).

Family conflict is associated with adolescent depression and suicidality. Whether the conflict level differs among adolescents based on presenting concern is unknown. This study compared family conflict between adolescents with self-injurious thoughts and behavior (SITB), those with depression, and healthy controls with neither condition.

Deaths by suicide have significant impacts on those bereaved. This study examined the utilization of supports by adults bereaved by suicide and associations with personal growth.

Suicide on railways cause immense emotional distress for families, bystanders, and railway staff and carries substantial economic costs. Although behaviors suggesting ambivalence have been identified in individuals dying by suicide at railway stations, relatively little is known about this phenomenon. We conducted a scoping review to examine the prevalence and characteristics of ambivalence among individuals who died by suicide at railway stations and, secondly, to identify factors, which may influence ambivalence in the suicidal process.

According to the Cognitive Emotional Model of Non-Suicidal Self-Injury (NSSI), this behavior is governed by a complex interplay of NSSI-related cognitions (i.e., a person's expected outcomes of self-injury and self-efficacy to resist NSSI) and emotion-regulatory strategies (i.e., cognitive reappraisal and expressive suppression). To empirically test this proposition, the current study examined the moderating roles of self-efficacy to resist NSSI, cognitive reappraisal, and expressive suppression in the relationships between outcome expectancies and NSSI frequency among university students.

Harsh parenting is a family risk factor that can lead to non-suicidal self-injury (NSSI) in adolescents. Based on the developmental psychopathology model and the identity disruption model, this study aimed to investigate the mechanism underlying the relationship between harsh parenting and NSSI using a one-year longitudinal design. Specifically, the study focused on the mediating role of identity confusion and the moderating role of intentional self-regulation in this association.

Suicide is the second leading cause of death for adolescents globally. Offset (both early and late) pubertal timing exposes adolescents to additional biological and psychosocial challenges, rendering them at heightened risk for psychopathology. Few studies have examined the relations between pubertal timing and suicidal ideation and attempts, as well as associated underlying mechanisms.

Healthcare services are potential interventions points before suicide. The aim of the current study was to explore whether mental health (MH) multimorbidity is associated with contact with healthcare services before suicide.

Families are amongst those most impacted by a suicide attempt. Young people exposed to the suicide attempt of a family member experience high levels of distress and are at risk of suicide themselves. Yet, there is a lack of knowledge about their lived experience and needs. Thus, this study aimed to explore the lived experience of young people with a family member who has attempted suicide.

Autobiographical memory, a critical cognitive process for recalling personal events, is closely linked to mental health. Depressive disorders are characterized by overgeneralized and negative memory patterns, which impair future-oriented thinking and exacerbate hopelessness. Current evaluations of autobiographical memory are subjective and limited by human bias. In this study, we applied Natural Language Processing using Large Language Models (LLMs) to analyze autobiographical memory narratives, uncovering that their valence can predict depression, suicidal ideation, and prior suicide attempts. Furthermore, valence correlated with core components of the Three-Step Theory of suicide, such as hopelessness and lack of connectedness. By integrating advanced computational techniques, our approach demonstrated high predictive accuracy and offers a scalable, objective method for assessing suicide risk. These findings highlight the potential of LLM-based analysis in enhancing psychological assessment and informing interventions, paving the way for innovative clinical applications in mental health care.

Suicide is a significant global public health issue, with occupations like farming-marked by financial instability and isolation-facing elevated risks. Despite international evidence, suicidality among Austrian farmers remains unstudied. This study compared suicidal ideation between Austrian farmers (n = 2,006) and the general population (n = 2,007), while identifying sociodemographic, occupational, and behavioral risk factors of suicidality in farmers.

Research indicates that non-heterosexual students face a higher risk of suicidal thoughts and attempts compared to heterosexual peers. However, differences in suicidal behavior between sexual orientation groups among students in Lithuania remain underexplored.

Given the well-documented association between emotion regulation (ER) deficits and suicidal thoughts and behaviors (STBs), and the limited understanding of their neural mechanisms, we reviewed studies across five databases that included validated ER tasks and neuroimaging techniques such as functional magnetic resonance imaging and electroencephalography. This systematic review synthesizes evidence from 11 neuroimaging studies to explore the neural correlates of ER deficits in individuals with STBs. Findings revealed that individuals with STBs exhibit heightened activation in the dorsolateral and ventrolateral prefrontal cortex during ER tasks, alongside increased amygdala reactivity to negative stimuli (e.g., sad facial expressions), in implicit ER paradigms. Heterogeneity in prefrontal cortex activation suggests that task- and population-specific neural signatures may influence these patterns. Our review also identifies methodological limitations in the current literature, including a reliance on cross-sectional designs and small sample sizes, which limit generalizability. These limitations highlight the need for longitudinal and multi-modal studies to better understand the dynamic neural patterns associated with ER and STBs. By elucidating the neural underpinnings of ER deficits in STBs, these findings may enable earlier identification of at-risk individuals and the development of personalized, targeted interventions (e.g., transcranial magnetic stimulation).

Individuals who have experienced suicidal thoughts or behaviors report experiencing stigma from social contacts and treatment providers. Although research has measured experiences of stigma related to suicide, tools measuring destigmatizing or adaptive cognitions related to suicide are limited. This study adapted a resource from NowMattersNow.org listing 10 things people with lived experience of suicide said they wished they knew when they were suicidal. These 10 things were modified into pilot items for the development of a measure of adaptive cognitions about suicide. Participants ( = 1,258) completed the pilot items, demographic items, and convergent/divergent measures. The sample was randomly split 25% ( = 314)/75% ( = 944) for exploratory and confirmatory analyses. Exploratory factor analysis, confirmatory factor analysis, internal consistency estimates, measurement invariance testing, and correlations with other measures were performed. A two-factor model was identified, with one factor related to coping beliefs and one factor related to destigmatizing beliefs. Four items that did not clearly load into the two identified factors were dropped, leaving six items in the final scale (three for each factor). This obtained a good fit in a CFA framework. Scores on the two factors correlated in the expected directions with measures related to stigma, mental health, and experiences with suicide. The measure was invariant across gender. However, lower-than-desirable internal consistency estimates were obtained. The resultant measure, the Adaptive Suicide Cognitions Scale, assesses two constructs that may be useful to examine further, with the goal of reducing the severity and impacts of suicide-related stigma.

Suicide is widely acknowledged as a pervasive global public health issue. Support for those bereaved by suicide (postvention) is a neglected area of research. Suicide loss survivors struggle with guilt, stigma, and a drive to comprehend. This study aimed to assess the ramifications of bereavement by suicide within a cohort of peer-support group members.

We aimed to examine the associations between various magnitudes of declines in the Taiwan Stock Exchange Capitalization-Weighted Stock Index (TAIEX) and suicides on the day following these declines and its possible moderating effects.

Previous research has linked NSSI to various psychological, social, and environmental factors, but the relative importance of these factors across different developmental stages remains unclear. This study investigates the multidimensional factors associated with NSSI among middle and high school students in China using a Random Forest Classifier to inform targeted interventions.

Cross-sectional and qualitative studies suggest that online peer counseling have potential benefits in addressing suicidality among adolescents and young adults. The present study aims to evaluate the effectiveness of [U25], a low-threshold online peer counseling service provided in Germany.

Non-suicidal self-injury (NSSI) is a significant global public health concern among adolescents. Prior research has confirmed the importance of perceived family invalidation in contributing to NSSI engagement. However, the mechanism underlying this association remains unclear. The current study hypothesized that perceived family invalidation would be associated with NSSI through a serial mediation pathway via shame-proneness and depressive symptoms. A sample of 3,875 Chinese adolescents from 12 to 18 years old ( = 14.43,  = 1.38, 50.8% females) completed self-report questionnaires with outcome variables of perceived family invalidation, shame-proneness, depressive symptoms, and NSSI. Results showed that the prevalence of lifetime NSSI was 13.6%. Perceived family invalidation, shame-proneness, and depressive symptoms were all positively correlated with NSSI. The mean scores of all variables in the NSSI group were significantly higher than the non-NSSI group. The association between perceived family invalidation and NSSI was not directly mediated by shame-proneness. Still, it was mediated by depressive symptoms, while this link was also serially mediated by shame-proneness and depressive symptoms. Findings demonstrate a potential psychopathological mechanism underlying the pathway from perceived family invalidation to NSSI through shame-proneness and depressive symptoms. Furthermore, it provides empirical evidence for future specific intervention and prevention directions for mental health services providers working with adolescents of elevated perceived family invalidation as well as shame-proneness to reduce the risk of NSSI.

Conducting youth suicide research comes with inherent challenges related to topic and age sensitivities. Despite this, there is a paucity of knowledge about how young people experience their research involvement. This study aimed to explore the experiences of young people with lived or living experience of suicide of being involved as collaborators or participants in suicide research.

Suicidality is a critical public health concern, especially among emerging adults who have experienced trauma. However, limitations remain in understanding the associations of suicidal risk and stress-responding. The current study experimentally evaluated the extent to which suicidal thoughts and behaviors (lifetime ideation/attempts, past-year suicidal ideation, threat of suicide attempt, likelihood of suicide in the future) were associated with self-reported psychological and physiological reactivity to a trauma-relevant stress induction task breathing tasks.

Text-based crisis services often gather information on users' suicide risk prior to intervention. 's crisis chat service uses a triage questionnaire combining a screening question on suicidal intent with the Suicidal Ideation Attributes Scale (SIDAS) to help identify users at highest risk. This study aimed to: (1) evaluate the SIDAS's psychometric properties in a real-world setting; and (2) assess its predictive validity in identifying users likely to be classified as high risk by counselors; and (3) examine whether combining the SIDAS with the suicidal intent question improves detection of high-risk users.
