In recent years, the prevalence of non-suicidal self-injury (NSSI) and suicidal ideation (SI) has been continuously increasing among adolescents, making it a global public health concern. While previous studies have identified a close relationship between NSSI and SI, few have delved into their reciprocal relationship and the underlying mechanisms.

The 15%-20% of adolescents worldwide who engage in nonsuicidal self-injury (NSSI) face an increased risk of transitioning from suicidal ideation to suicide attempt. To resist NSSI urges, young people often seek peer support online. We examined adolescent help-seeking on a purpose-built online mental health peer support platform, which is a critically understudied help-seeking venue.

Suicide is a major public health problem in the United States. This retrospective exploratory study examined clinician-identified state-related risk factors observed within 30 days prior to death by suicide, comparing 24 decedents with psychosis-related suicide and 133 non-psychosis-related suicide. A secondary descriptive analysis was conducted for 47 patients who were evaluated and denied suicidal ideation within 48 h of death by suicide.

In 1997, the Heaven's Gate religious group died by mass suicide. Before their deaths, many members left videotaped final messages ("exit statements"), recording a functional equivalent to a suicide note. This study used natural language processing to compare the proportion of emotion keywords present in these statements to a collection of traditional suicide notes to examine whether the psychological state of individuals differs from more traditional cases of suicide.

Suicide is the second leading cause of death in adolescents in the United States. There is an urgent need to advance understanding of risk mechanisms in adolescents to guide early interventions. While prior research has implicated cognition, neural connectivity, and psychopathology in relation to adolescent suicidal ideation (SI) and nonsuicidal self-injury (NSSI), there is a relative lack of clarity regarding the causal structure of these factors, particularly in early adolescence.

In the past two decades, suicide attempts and deaths involving prescription opioids have sharply increased. Research is needed to understand how prescription opioid misuse may increase suicide risk. Contemporary suicide theories suggest opioid use may increase suicide capability by increasing pain tolerance, altering fears related to death, or increasing one's understanding of lethal doses and/or access to means. This study examined the role of these dimensions of suicide capability in the association between prescription opioid misuse and self-reported likelihood of future suicidal behaviors.

Sleep disturbances are established risk factors for suicidal thoughts and behaviors (STB) in adolescents. Nightmares are understudied in this context. The Interpersonal Psychological Theory of Suicide (IPTS) proposes that suicide ideation (SI) alone is not a risk factor for suicide attempt (SA); instead, high levels of SI interact with capability (i.e., factors that enable ideators to make attempts). Through the lens of the IPTS, this study explored the role of nightmares as correlates of variables associated with STB and as potential indicators of capability.

Suicide is a leading cause of preventable death worldwide, with approximately 700,000 individuals dying by suicide annually. Recent studies have highlighted the importance of text-based risk assessments and the use of artificial intelligence technologies such as ChatGPT in suicide prevention. This study examined how intolerable interpersonal situations influence text communication, focusing on the relationship between perceived burdensomeness and the expression of apologetic messages.

Caring Cards is a novel adaptation of caring contacts, where Veterans with a history of suicidality (card makers) create cards for Veterans with active suicidality (recipients). Aims included (1) establishing Caring Cards' feasibility and acceptability, including an optional meetup group, and (2) evaluating pre-/postchanges in thwarted belongingness, perceived burdensomeness, social connectedness, and suicide ideation. Participants included 30 card makers and 50 recipients receiving care at a Veterans Affairs Center. Groups of 5-10 card makers met weekly for 3-6 months to create cards; recipients received cards monthly for 6 months. Outcomes were collected at baseline and follow-up (one month postparticipation completion). Card makers demonstrated marginal feasibility (69.4% average attendance). Card maker attrition was greater than expected (60%). These rates may have been impacted by COVID-19. Card maker follow-up was feasible (70%). There was 0% attrition for recipients; however, follow-up was marginally feasible (68%). The optional meetup group was not feasible (36.4% attendance). All participants found the intervention acceptable (> 75% average satisfaction). There were no significant pre-/postdifferences across card maker outcomes. Recipients reported significant reductions in thwarted belongingness (d = 0.27) and perceived rejection (d = 0.41). Results highlight the promise of Caring Cards as a low-cost, highly scalable intervention.

Among patients with substance-related disorders (SRDs) and suicide attempts in 2014-2021, we identified care trajectories within a 3-year period preceding their last suicide attempt (index date). We also determined associations between care trajectories and patients sociodemographic and clinical characteristics, quality of care received, and risk of death in the following year.

Active suicidal ideation and passive suicidal ideation are distinct but related constructs, each carrying significant clinical implications. However, their real-time predictors remain underexplored in intensive longitudinal studies. This ecological momentary assessment (EMA) study investigated the associations of thwarted belongingness (TB), perceived burdensomeness (PB), and hopelessness with changes in both types of ideation at 2-4 h intervals, and whether a history of suicide attempts moderates these relationships.

Gendered racism, which emasculates and denigrates the masculinity self-concept and the desirability of Asian American men, has been associated with greater endorsement of suicide ideation. However, no research has examined culturally informed gendered racial factors that could moderate the risk of suicide ideation associated with gendered racism. Based on the potential of affirming gendered racial experiences that can validate and empower Asian American men to resist internalizing the harms of gendered racism, we examined whether affirmative body positive and positive intimacy experiences could moderate the link between gendered racism and suicide ideation.

The fearlessness about suicide scale (FSS) was developed in response to evidence suggesting fearlessness about suicide is more relevant to the capability for suicide than fearlessness about death. To extend its psychometric validation, this study provides a cross-sectional comparison of the FSS and the acquired capability for suicide-fearlessness about death (FAD) scale.

Brief contact interventions (BCI) refer to short messages delivered proactively to a specific target population. The aim of this study was to test the effectiveness of a mobile phone short-message service (SMS) BCI for people bereaved by suicide.

Both daily stressful events and suicidal ideation (SI) are common experiences in adolescence. Different sources of stress have been associated with SI, but few studies have compared how they might differentially predict short-term SI.

While Joiner's Interpersonal Psychological Theory of Suicidal Behavior (IPTSB) has been shown relevant to understanding suicide behaviors among Ghanaian adolescents, the integration of sociocultural factors into the theory is important due to Ghana's diverse cultural setting.

The Interpersonal Theory of Suicide (ITS) identifies key dynamic factors, including thwarted belongingness, perceived burdensomeness, and interpersonal hopelessness, that may aid in assessing and preventing suicidal thoughts and behaviors. These constructs can also be understood within the framework of the Five Factor Model (FFM) of personality. This study aimed to examine the relationship between personality profiles, the severity of suicide-related histories, and ITS-related risk factors. Additionally, we sought to determine whether the relationship between ITS-related risk factors and the severity of suicide-related histories was moderated by personality profiles.

Suicide stigma is a multifaceted social issue with far-reaching consequences for mental health. While previous research has linked it to suicidal thoughts and behaviors (STBs), the roles of perceived and internalized forms of suicide stigma in influencing STBs remain unclear.

This study examines longitudinal models of self-directed violence among 584 Black people (44% female) in a community-based sample living in areas of concentrated disadvantage.

We investigated predictors of suicide among Add Health longitudinal survey participants with over 20,000 high school students using National Death Index (NDI) mortality records, exploring behavioral, attitudinal, and demographic correlates of suicide risk.

Despite the burgeoning literature on mental health problems during the COVID-19 pandemic, little is understood about the heterogeneous developmental trajectories of depressive symptoms and their subsequent mental health outcomes.

The Brief Suicide Cognitions Scale (B-SCS) is a self-report measure of suicidogenic cognitions. This study evaluated measurement invariance of the B-SCS among different subgroups. Secondarily, this study sought to evaluate the replicability of the psychometric validity, reliability, and factor structure of the B-SCS.

Suicidal crises can occur when a clinician is not available to intervene. Safety planning-type interventions, such as the Crisis Response Plan (CRP) and the self-guided Safety Plan (SP), were developed to provide patients with skills to manage their suicide risk in daily life. These plans are similar in makeup, but differ in terms of how they are created. This study examined whether plan type moderated associations between frequency of plan use and suicide ideation and affect.

Emphasis on medical severity when assessing the lethality of suicide attempts may overlook important contextual factors. We examined if distinguishing between medical severity and chance of rescue improves evaluation and understanding of suicidal mental states.

Assessing suicide risk in clinical settings is challenging, as conventional self-report scales have limited predictive validity. The Death Implicit Association Test (D-IAT) was developed to explore implicit associations related to death and the self-concept. However, it omits the emotional association with death that may be crucial in suicide risk assessment. This cross-sectional study on individuals with current suicidal ideation integrates the implicit emotional association with death into the conventional D-IAT.

US Veterans are at higher risk for suicide compared to the general population. Access to evidence-based practices for suicide prevention (EBP-SPs) is limited; however, emerging research supports the delivery of EBP-SPs through telehealth. The Veterans Health Administration's (VHA) Suicide Prevention (SP) 2.0 Clinical Telehealth Program aims to increase nationwide access to EBP-SPs for Veterans with recent suicidal self-directed violence (SSDV). This paper describes initial outcomes of SP 2.0's Cognitive Behavioral Therapy for SP (CBT-SP).

Suicidal ideation and attempts as well as eating disorders (EDs) are common among Iranian individuals. Additionally, ED symptoms are associated with suicidality. According to the interpersonal-psychological theory of suicide (IPTS), factors such as thwarted belongingness, perceived burdensomeness, and capability for suicide must combine for suicidality to occur. The tenets of IPTS have been supported among individuals with ED symptoms from Western countries. However, no study has yet explored how ED symptoms might co-occur with IPTS factors and potentially relate to suicidal ideation and attempts using latent profile analysis (LPA).

Nondisclosure of suicidal ideation (SI) presents a challenge to assessing suicide risk, as assessments often rely on self-reported SI. Cross-national comparisons of rates of, and reasons for, SI nondisclosure remain understudied. The present study examined whether rates of SI nondisclosure from clinicians differed, and if there were differences in rates of reasons for SI nondisclosure, across 12 countries.

Increases in suicide attempts in preadolescents represent a serious public health concern. This study aimed to identify prospective and concurrent risk factors that differentiate children with suicidal ideation (SI) from those with a suicide attempt (SA) across childhood.

Major depressive disorder (MDD) is associated with maladaptive self-reported interoception, that is, abnormal bodily self-experience. Although diminished body trust predicts suicidal ideation, interoceptive measures have not been considered in depressed inpatients, whose suicide risk regularly peaks post-discharge. This study aims to explore interoceptive characteristics at admission that help identify inpatients at risk for suicidal ideation at discharge.
