    1NewViolent and Nonviolent Suicidal Ideation: Predictors of Suicide Crisis Syndrome Severity in a Longitudinal Study
    Yukti Bhatt, Victoria Witerska,Lisa J. Cohen, Erin Wheeler,Sarah Bloch‐Elkouby, Benjamin N. Johnson, Yael Apter Levy, Ortal Shimon Raz,Igor Galynker

    ABSTRACT Background Suicide Crisis Syndrome (SCS), an acute cognitive‐affective state, has been shown to predict near‐term suicidal behaviors, highlighting the need to understand factors associated with its severity. This study examined the relationship between SCS severity and different types of suicidal ideation (violent, nonviolent, and passive). Methods 622 adult psychiatric inpatients were assessed at intake, discharge, and one‐month post‐discharge follow‐up. Suicidal ideation types (SI) were collected using the Columbia‐Suicide Severity Rating Scale and classified as violent, non‐violent, or passive. One‐way ANOVA, repeated measures ANCOVA, and binary logistic regressions examined SCS differences and temporal patterns across ideation types. Results SCS severity significantly differed by ideation type. Individuals with violent SI had higher SCS severity than those with passive SI. In the exploratory analysis ( N = 56), violent SI showed a steady decline, whereas nonviolent SI increased at one‐month follow‐up. Greater SCS severity at discharge also predicted nonviolent ideation at one‐month follow‐up. Conclusions SI content may provide different information across stages of an acute suicidal crisis. Violent SI may be relevant to concurrent crisis severity, whereas nonviolent SI may warrant attention during the post‐discharge period. Assessing SCS severity alongside SI content may provide a more nuanced understanding of acute risk.

    2NewFeasibility, Acceptability, and Preliminary Outcomes of a Group‐Based Brief Cognitive‐Behavioral Therapy Protocol for Suicide Prevention in a Brazilian Public Mental Health Service: A Mixed‐Methods Pilot Study

    ABSTRACT Introduction We evaluated the feasibility, acceptability, and preliminary outcomes of group‐adapted brief cognitive‐behavioral therapy for suicide prevention (BCBT) in a Brazilian public psychiatric outpatient service. Methods This single‐arm, nonrandomized, mixed‐methods pilot enrolled 27 adults across two cohorts receiving 16 weekly group sessions. Feasibility and acceptability were assessed, and suicidal ideation was monitored weekly using the Beck Scale for Suicide Ideation (BSI). Results Enrollment targets were met; 70.4% had ≥ 4 recorded sessions, and no intervention‐related adverse events were recorded. All six questionnaire respondents rated recommendation at 8–10. Four provided qualitative responses, highlighting shared suffering recognition and an interpretive theme of hope instillation. The linear BSI slope was nonsignificant ( B = −0.29, p = 0.129); multiple imputation yielded B = −0.36 ( p = 0.018). An exploratory quadratic model indicated greater decline later in treatment ( p = 0.008). Among 18 participants with ≥ 4 recorded sessions and baseline BSI, scores decreased by 8.2 points from baseline to the last observation ( d = −0.67; p = 0.011). Conclusions Group‐adapted BCBT showed preliminary feasibility and acceptability, with uncontrolled signals of reduced suicidal ideation. Controlled evaluation is needed to establish efficacy.

    3NewImproved Social Functioning Mediated the Effects of Adolescents' Sports Participation on Self‐Harm and Psychological Wellbeing: A Prospective Cohort Study
    Mark Lawrence Wong

    ABSTRACT Introduction The prevalence of self‐harm, regardless of the presence of suicidal intent or not, has been increasing, and effective and accessible intervention strategies are needed. This study investigated whether sports participation in adolescence serves as a protective factor against the future development of self‐harm or poor psychological wellbeing, as well as the relevant psychosocial mechanisms. Methods A secondary data analysis was conducted using a nationally representative cohort in the United Kingdom, in which participants ( n = 7361, 55.4% female) completed measures of sports participation (age 17), the number of close friends (age 19), life satisfaction (age 20), and self‐harm and poor psychological wellbeing (age 25). Results More frequent sports participation was prospectively associated with a lower risk of self‐harm and better psychological wellbeing. Path analyses supported a significant serial mediation model whereby the effects of sports participation on self‐harm and psychological wellbeing are mediated by an increased number of close friends and higher levels of life satisfaction. Conclusion These findings indicate that sports participation has potential value in optimizing mental health, particularly in reducing the likelihood of self‐harm and improving psychological wellbeing. In addition, improved social relationships and life satisfaction mediated the impact of sports participation on self‐harm and psychological wellbeing. Overall, the findings lay a solid foundation for further testing the benefit of encouraging sports participation among adolescents to optimize interpersonal functioning and mental health outcomes.

    4NewImplementation of Mobile Health Intervention Targeting Belongingness and Burdensomeness: an Ecological Momentary Assessment Study of Self-Injurious Thoughts and Behaviors in LGBTQ+ Individuals.
    Konrad Bresin, Michaela S Ahrenholtz, Julia K Nicholas, MacKenzie Bewley

    OBJECTIVE:The goal of this paper was to test a mobile health intervention designed to reduce self-injurious thoughts and behaviors in LGBTQ+ individuals. The intervention consisted of brief messages aimed at increasing feelings of belongingness and meaning. METHOD:We recruited LGBTQ+ individuals (N = 55) with past-month self-injurious thoughts and/or behaviors. Participants completed 14 days of ecological momentary assessment (EMA) of minority stress, thwarted belongingness, perceived burdensomeness, and self-injurious thoughts and behaviors. Then, participants were randomly assigned to receive brief messages designed to instill belongingness and meaning/purpose, or no intervention for 14 days. Then, participants completed an additional 14 days of EMA. RESULTS:Our results showed that participants in the control condition had significant increases in self-injurious thoughts and planning over time, whereas those in the intervention condition showed no significant change. For self-injurious behavior, thwarted belongingness, and perceived burdensomeness, there were significant decreases in the intervention condition, but no changes in the control condition. CONCLUSIONS:These results provide support for the interpersonal theory of suicide and indicate a potentially scalable mobile health intervention. PUBLIC HEALTH SIGNIFICANCE:This paper found evidence that a brief mobile health intervention reduced suicidal and non-suicidal self-injurious thoughts and behaviors among LGBTQ+ individuals.

    5NewNighttime Sensory-Behavioral Activation and Admission Suicidality in Young Inpatients with Major Depressive Disorder: A Retrospective Clinical-Record Study.
    Xinqi Huang, Xiaolong Kuang, Hongxing Wang

    INTRODUCTION:Suicide risk assessment during psychiatric admission may benefit from clinically observable information beyond overall depressive symptom severity. This study examined whether clinician-documented nighttime sensory-behavioral activation was associated with admission suicidality in young inpatients with major depressive disorder (MDD). METHODS:This retrospective study included 406 inpatients aged 15-35 years with moderate-to-severe MDD. Nighttime sensory-behavioral activation was coded as none, recurrent, or marked. The primary outcome was admission suicidality, defined as suicidal ideation or behavior during the index depressive episode. Logistic regression models adjusted for age, sex, HAMD-17 score excluding suicide and insomnia items (Items 3-6), and documented precipitating stressor type. Severe social role impairment and thyroid indicators were secondary and exploratory outcomes. RESULTS:After adjustment, recurrent activation (OR = 2.00, 95% CI 1.17-3.43) and marked activation (OR = 1.96, 95% CI 1.12-3.43) were associated with higher odds of admission suicidality. Marked activation was associated with severe social role impairment (OR = 2.47, 95% CI 1.42-4.30). Thyroid indicators did not account for these associations. CONCLUSION:Nighttime sensory-behavioral activation was associated with admission suicidality and, at the marked level, severe social role impairment. These findings are preliminary and warrant prospective validation using standardized measures.
