Effectiveness Study of a Cultural Adaptation of Cognitive-Behavioural Therapy-Based Application for Depressive Symptoms in College Students: A Randomised Controlled Trial.

Studies on mental health applications among college students lack empirical evidence regarding mobile application usage's intensity, duration and frequency. To evaluate the effectiveness of a cognitive-behavioural therapy (CBT)-based mobile application in ameliorating depressive symptoms among college students. A randomised controlled trial was conducted at three universities. Undergraduates aged ≥ 20 years with self-reported depressive symptoms were recruited and randomly assigned to the control and intervention groups. The outcomes include changes in depressive symptoms, suicidal ideation, help-seeking attitudes and emotional self-awareness at 4 (T1), 8 (T2) and 12 (T3) weeks. An intention-to-treat analysis was conducted. Of the 91 participants, 46 in the intervention group exhibited a significant decline in depressive symptoms at T1 and lower patterns of symptom changes at T2 and T3. No significant differences were observed in the other outcomes; however, higher help-seeking attitude, emotional self-awareness and lower suicidal ideation after T0 were observed for those who used the application for 12 weeks. The advantages of a brief application-based intervention to promote college students' psychological health are outlined. School nursing managers could use the application to improve the college mental health systems and support collegial teacher-student relationships. Further studies should enhance application usage to manage depressive symptoms. The study was approved by the Research Ethics Committee of the National Taiwan University Hospital (No. 202108098RINB, Date of approval: Oct 27, 2021) and the National Institutes of Health (No. NCT05188950).

Efficacy of racemic ketamine or esketamine monotherapy for reducing suicidal ideation in uni- or bipolar depression: a systematic review and meta-analysis.

The current systematic review and meta-analysis examined the effect of racemic ketamine or esketamine on suicidal ideation in individuals with uni- or bipolar depression. We searched the MEDLINE, Embase, Central, PsycINFO, and Web of Science databases to identify randomized controlled trials that examined the effect of racemic ketamine or esketamine monotherapy on suicidal ideation (SI) in individuals with uni- or bipolar depression. The two monotherapies were compared; the primary outcome was the rate of remission of SI, and the secondary outcome was the SI score. The risk ratio was used as an effect size measure for binary variables, while the standardized mean difference was used as an effect size measure for continuous variables. Our meta-analysis included 13 randomized controlled trials involving 1,1109 individuals with uni- or bipolar depression. Patients receiving racemic ketamine monotherapy had a significantly higher acute SI remission rate than those receiving placebo or midazolam (RR = 2.06, 95% CI 1.47 to 2.91, P < 0.0001). Racemic ketamine also led to significantly lower SI scores than placebo or midazolam (SMD = -0.36, 95% CI -0.71 to -0.01, P = 0.04). The evidence for the treatment of SI with esketamine was inconsistent. The pooled effect sizes for long-term anti-SI effects did not reveal significant differences between therapies. Our study indicated the efficacy of racemic ketamine monotherapy for rapidly and transiently reducing SI in individuals with uni- or bipolar depression, but the efficacy of racemic ketamine monotherapy against long-term suicidal ideation remains unclear. There is not -sufficient evidence to support the anti-suicidal effects of esketamine monotherapy.Protocol registration: Prospero registration number: CRD42023434380.

Trajectories and predictors of suicidal ideation in clinical characteristics and pharmacological treatments for major depressive disorder: a study based on a national multi-centered prospective cohort

Suicidal ideation (SI) is a significant precursor and risk marker for suicide behaviors in major depressive disorder (MDD). Exploration of SI trajectory from a longitudinal framework are essential for treatment guidelines and clinical management of suicide risk. This study sought to explore SI trajectories and its associated clinical, sociodemographic characteristics, and initial treatment among patients with MDD. We used data from a non-interventional, national multi-centered prospective cohort study. 1 461 patients with MDD were included in the growth mixture modeling using SI at baseline, 2 weeks, 4 weeks, 8 weeks, 12 weeks, and 6 months, 9 months, and 12 months as the indicator. A multinomial regression was employed with SI trajectory as the outcome and anhedonia, depressive symptoms, atypical depressive symptoms, pharmacological treatments, and other covariates as the predictors. Four distinct SI trajectories were identified: a consistently low SI trajectory(50.7%), a persistently mild SI trajectory(20.6%), a fast declined SI trajectory(8.9%), and a slowly declined trajectory(19.8%). Compared to those with a consistently low SI trajectory, a higher score of anhedonia was associated with an increased risk of experiencing persistently mild (RRR = 1.20, 95%CI: 1.05, 1.38) and slowly declined SI (1.54, 95%CI: 1.32, 1.80). Severity of depressive symptom was also positively associated with the risk of experiencing persistently mild (1.15, 95%CI: 1.13, 1.18) and slowly declined SI (1.17, 95%CI: 1.14, 1.21). And the risk of experiencing slowly declined SI was higher for those use SSRI(1.49, 95%CI: 1.02, 2.31), and for those use antidepressant and antipsychotic/mood stabilizer combined therapy (3.78, 95%CI: 1.48, 9.61). The findings of this study are potentially useful for clinical practice as critical indicators of profiles and interventions for prognosis among patients with MDD. Further research is warranted to explore potential modifiable factors and the association between SI trajectories and suicide behavior.

Dhillo: None. C.N. Jayasena: None. Context: Anabolic-androgenic steroids (AAS) are misused by millions of men worldwide to boost muscle size and physical performance. Recent studies have quantified the recovery of cardiovascular markers and testicular function following AAS cessation. Qualitative studies demonstrate that low mood, anxiety, suicidal ideation, and sexual dysfunction are also common following AAS cessation. However, no previous study has focused on quantifying symptoms within the first year of AAS cessation, nor investigated independently associated factors for these symptoms. Methods: Cross-sectional, observational study of 165 men in 3 groups; non-AAS (n=43); current-AAS (n=76); past-AAS ≤1 year (n=46). All participants completed questions on substance misuse, Beck Depression Inventory-II (BDI-II), International Index Erectile Function-15 (IIEF-15), General Anxiety Disorder (GAD-7), Quality-of-life (SF-36), and underwent fasting, morning blood sampling with urine toxicology. Results: As expected, current-AAS had lower gonadotropins and elevated serum total testosterone compared with past-AAS and non-AAS. Sexual function measured using IIEF-15 was impaired in men stopping AAS &amp;lt;1year (past-AAS) compared with current AAS users: (1) total: 69.0 [95% CI 64.0, 71.0], current-AAS; 61.0 [95% CI 56.0, 66.0], past-AAS; p=0.077; (2) erectile function: 30.0 [95% CI 29.0, 30.0], current-AAS; 28 [95% CI 21.0, 29.0], past-AAS; p=0.015; (3) sexual desire: 9.0 [95% CI 8.0, 10.0], current-AAS; 6.0 [95% CI 5.0, 8.0], past-AAS; p&amp;lt;0.0001; (4) overall satisfaction: 10.0 [95% CI 8.0, 10.0], current-AAS; 7.0 [95% CI 7.0, 8.0], past-AAS; p=0.002. Multivariable analysis suggested that psychiatric comorbidity (coefficient -6.5 [95% CI -13.0, -1.3] p=0.03) and AAS cessation (coefficient -10.8 [95% CI -5.6, -17.2]; p&amp;lt;0.001) were associated with lower total IIEF-15 scores.Depression scoring was worse in the past-AAS group compared with non-AAS: BDI-II 4.0 [95% CI 2.0, 7.0], non-AAS; 7.0 [95% CI 4.0, 16.0], past-AAS; p=0.0448. Multivariable analysis suggested that psychiatric comorbidity (OR 2.39 [95% CI 1.60, 3.57]; p&amp;lt;0.001) and lower serum total testosterone (OR 0.85 [95% CI 0.88, 0.94]; p=0.002) were associated with higher BDI-II scores.Energy and fatigue measured using SF-36 was lower in the past-AAS group compared with non-AAS: 70 [95% CI 65, 75], non-AAS; 60 [95% CI 50, 65], past-AAS; p=0.0498. No significant differences in anxiety scoring were detected. Discussion: We report the first, detailed quantification and modelling of symptoms in men currently misusing and stopped AAS within the previous year. These data reveal potentially treatable factors to improve symptoms of AAS cessation if proven within interventional studies. Presentation: 6/2/2024

Project Yarn Circle: development and pilot evaluation of a cultural connection suicide prevention program for Aboriginal and Torres Strait Islander young people

ABSTRACT Background Aboriginal and Torres Strait Islander young people experience markedly higher suicide mortality than non-Indigenous youth in Australia, yet there is little evidence of effective preventative strategies. Many are misaligned to the needs of First Nations young people due to a lack of consideration of protective factors such as community and cultural connection. Objective To date no research has examined whether increasing cultural connectedness may reduce Aboriginal and Torres Strait Islander youth suicidality. The current study outlines the development, implementation, and pilot evaluation of Project Yarn Circle, a school-based suicide prevention initiative utilising cultural education and connection. Method Project Yarn Circle was piloted by an Indigenous owned and managed youth mental health organisation, delivering 5 weekly sessions to 276 young people at 9 schools in Southeast Queensland, Australia, between 2019 and 2023. Sessions connected students to cultural knowledge and practices (stories, painting, dance, Indigenous languages) with Elders and local cultural knowledge facilitators. Results Pre- and post-program evaluation questionnaires completed 6–8 weeks apart found that participants had significantly lower suicidal ideation (GHQ-18-SS), pre 7.16, post 6.61, p = .043 higher positive ideation/reasons for living (PANSI-PI) pre 22.44, post 23.60, p = .009, and higher self-esteem (RSES) pre 16.55, post 23.60, p = .005. Analyses of cultural connectedness items co-designed for this evaluation study and validated using Exploratory Factor Analysis found that students demonstrated greater cultural identity clarity, peer cultural competence, strength from culture, salience of cultural continuity and sense of belonging. Conclusions These findings provide new evidence towards utilising cultural connectedness as an intervention mechanism in Indigenous youth suicide prevention.

Predicting suicidal ideation from irregular and incomplete time series of questionnaires in a smartphone-based suicide prevention platform: a pilot study

Over 700,000 people die by suicide annually. Collecting longitudinal fine-grained data about at-risk individuals, as they occur in the real world, can enhance our understanding of the temporal dynamics of suicide risk, leading to better identification of those in need of immediate intervention. Self-assessment questionnaires were collected over time from 89 at-risk individuals using the EMMA smartphone application. An artificial intelligence (AI) model was trained to assess current level of suicidal ideation (SI), an early indicator of the suicide risk, and to predict its progression in the following days. A key challenge was the unevenly spaced and incomplete nature of the time series data. To address this, the AI was built on a missing value imputation algorithm. The AI successfully distinguished high SI levels from low SI levels both on the current day (AUC = 0.804, F1 = 0.625, MCC = 0.459) and three days in advance (AUC = 0.769, F1 = 0.576, MCC = 0.386). Besides past SI levels, the most significant questions were related to psychological pain, well-being, agitation, emotional tension, and protective factors such as contacts with relatives and leisure activities. This represents a promising step towards early AI-based suicide risk prediction using a smartphone application.

Self-compassion, self-referential caudate circuitry, and adolescent suicide ideation

Suicide is the second leading cause of death in youth, and depression is a strong proximal predictor of adolescent suicide. It is important to identify psychological factors that may protect against suicide ideation in depressed adolescents. Self-compassion may be such a factor. Converging evidence indicates the inverse association between self-compassion and suicide ideation, but the neural mechanisms underlying their link remain unknown. Because self-referential caudate activity is associated with both self-compassion and suicide ideation, its functional connectivity might explain their relationship. In this study, we examined the relationship between self-compassion and caudate functional connectivity during self-appraisals, a typical self-referential paradigm, and their associations with suicide ideation in both depressed and healthy youth. In the scanner, 79 depressed youth and 36 healthy controls evaluated, from various perspectives, whether phrases they heard were self-descriptive. Self-compassion and suicide ideation were rated with self-report and interview-based measures. We found that self-compassion was associated with stronger left caudate functional connectivity with bilateral posterior superior temporal sulcus/temporoparietal junction, the left middle temporal gyrus (MTG), and the left middle occipital gyrus during positive versus negative self-appraisals. Stronger left caudate connectivity with the left MTG explained the association between higher self-compassion and lower suicide ideation, even controlling for non-suicide ideation depression severity, anxiety severity, and non-suicidal self-injurious behavior. The findings suggest that the left caudate to MTG connectivity during positive versus negative self-referential processing could be a biomarker to be targeted by neural stimulation interventions for reducing suicide ideation in depressed youth, combined with self-compassion interventions.

Interaction Effect of Childhood Abuse History and Suicidality on 12-Month Antidepressant Response in Patients With Depressive Disorder.

We aimed to identify the individual and interactive effects of childhood abuse and suicidal ideation on antidepressant treatment response in 12 months. In this prospective research, 1,262 depressive patients were asked about their childhood abuse history, suicidal ideation, and other clinical characteristics and socio-demographic features at baseline, and 1,015 of them were followed during 1 year of stepwise pharmacotherapy. The individual and interactive relationships of the childhood abuse history and suicidal ideation on 12-month antidepressant non-remission were explored by logistic regression with relevant covariates. Having a childhood abuse history and higher suicidal ideation significantly predicted a non-remission state in 12 months respectively. The interaction term of childhood abuse and suicidal ideation was also significantly related to a non-remission state at 12 months. To be specific, in the low suicidal ideation group, depressive patients with a childhood abuse history were more likely to be in a non-remission state after 12 months of medication. In the high suicidal ideation group, however, childhood abuse history was not significantly associated with the non-remission state at 12 months. The childhood abuse history and the level of suicidal ideation are informative factors predicting the long-term results of antidepressant treatment, especially when they are combined. Clinicians may consider antidepressants with a higher affinity for patients with childhood abuse history even if they don't have suicidal ideation. The cognitive intervention for suicidal ideation might be helpful in addition to pharmacological treatment.

Mindsets of suicide trajectories: An Linguistic Inquiry and Word Count analysis of suicide hotline conversations.

The aim of the study was to explore the psychological characteristics of the individuals with various suicide risks using computerized text analysis, in the hopes of a better understanding of suicide trajectories. 627 first-time callers' records were randomly selected from Taiwan An-Shin Hotline database between 2013 and 2018. The voice records were evaluated by two psychologists to determine the levels of suicide risk (156 with uncertainty of risk, 177 with low suicidal ideation, 157 with high suicidal ideation, and 137 with suicide preparation/attempt) and transcribed into text. The Linguistic Inquiry and Word Count 2015 (LIWC2015) program combined with Chinese dictionary were then used to calculate the frequency of word categories. Exploratory factor analysis identified four mindsets of language characteristics, named "opposition and questioning", "active engagement", "negative rumination", and "focus on death". Psychological descriptions of the mindsets were also obtained through correlation analysis with the LIWC2015 categories and indicators. The four mindsets effectively distinguished the callers with different levels of suicide risk. The psychological characteristics of people with various suicide risks can be described and differentiated via the closed-word categories and composite indicators. These results provide useful information for practitioners and researchers.

Reducing intrusive suicidal mental images in patients with depressive symptoms through a dual-task add-on module: Results of a multicenter randomized clinical trial.

To examine the safety and efficacy of a brief cognitive dual-task (using eye movements) add-on module to treatment as usual (TAU) in reducing the severity and frequency of intrusive suicidal mental images and suicidal ideation. We conducted a single-blind, parallel multicenter randomized trial (No. NTR7563) among adult psychiatric outpatients (N = 91; Mage = 34.4, SD = 13.54; 68% female) with elevated depressive symptoms and experiencing distressing suicidal intrusions in the Netherlands. Primary outcome was the severity (Suicidal Intrusions Attributes Scale) and frequency (Clinical Interview for Suicidal Intrusions) of suicidal mental imagery intrusions at 1-week posttreatment and 3-month follow-up. Primary analysis was intention-to-treat. Between November 27, 2018 and September 13, 2021, 91 patients were included and randomly assigned to intervention group (Cognitive Dual Task Add-on + TAU) (n = 46) or TAU-only (n = 45). Cognitive Dual Task Add-on + TAU had greater reductions in severity (mean difference, -15.50, 95% CI [23.81, -7.19]; p < .001, d = 0.60), and frequency (geometric mean difference, 0.47, 95% CI [0.29, 0.79]; p = .004) of suicidal intrusions over time than TAU-alone. Cognitive Dual Task Add-on + TAU patients also showed lower suicidal ideation over time (p = .008, d = 0.42). There were no significant group differences in reductions in depressive symptoms, rumination, or hopelessness. Four serious adverse events occurred (three Cognitive Dual Task Add-on + TAU; one TAU-only); all unlikely attributable to intervention/trial. Findings provide support for the effectiveness of adding a cognitive dual-task module to the treatment of psychiatric outpatients with elevated depressive symptoms in reducing suicidal intrusions and ideation and can be executed safely.

Mental health and wellbeing outcomes associated with social, medical, and legal gender affirmation among trans young people in Australia

Background Gender affirmation is known to improve mental health among trans adults, but its impact on young people has been questioned. This study examined the mental health outcomes associated with social, medical, and legal gender affirmation among trans young people in Australia. Methods Data from 1697 trans young people aged 14–21 who participated in an Australian national survey were analyzed using multivariable logistic regression analyses. We measured associations between gender affirmation and various mental health variables, including levels of happiness, psychological distress, anxiety, self-harm and recent suicidal ideation and suicide attempts. Associations between gender affirmation and young people’s wellbeing, including experiences of verbal harassment, homelessness, and drug use were also examined. Results Participants who had affirmed their gender legally and medically (via hormone therapy or surgery/ies) reported lower levels of anxiety and psychological distress, while legal gender affirmation was associated with lower suicidal ideation. Social affirmation was not directly associated with wellbeing outcomes but was linked to an increased likelihood of verbal harassment and homelessness. All forms of gender affirmation were associated with increased drug use, which likely reflects the greater opportunities for social connection and LGBTQ-community involvement that trans young people experience when they take steps to affirm their gender. Conclusion All forms of gender affirmation were positively associated with the wellbeing of trans young people. Though young people who had socially affirmed their gender faced higher likelihoods of experiencing verbal harassment and homelessness, this is likely linked to their increased visibility and subsequent vulnerability to discrimination. These findings highlight the need for targeted interventions to address transphobia and discrimination. A comprehensive approach to supporting the wellbeing of trans young people should include legal, medical, and social affirmation, as well as addressing potential negative outcomes via societal education.

Associations among intimate partner violence, suicidal ideation, suicide behaviors, non‐suicidal self‐injury, and psychological well‐being in Black American emerging adults

AbstractBackgroundSuicidal ideation and behavior and non‐suicidal self‐injury (NSSI) among Black emerging adults is a major public health concern. Intimate partner violence (IPV) is a significant risk factor for suicidal ideation and behavior and NSSI, but there is little work examining the buffering effect of psychological well‐being (PWB). The purpose of this study was to examine the associations between IPV, suicide ideation and behavior, and NSSI, and the moderating role of PWB on these associations.MethodSecondary data analyses were conducted using a subsample of Black American emerging adults (N = 4694) from the National College Health Assessment.ResultsIPV was associated with greater odds of suicide ideation, past‐year suicide attempt, and NSSI. PWB was associated with lower odds of suicide ideation, past‐year suicide attempt, and NSSI. PWB did not moderate the relationships between IPV and the outcomes.ConclusionsIPV was a risk factor for suicidal ideation, suicide attempt, and NSSI among Black American emerging adults. PWB was associated with lower suicidal ideation and behavior and NSSI engagement, suggesting it can be a protective factor. Bolstering PWB in Black communities may be beneficial in intervention and prevention efforts.

Can sports participation be a protective factor against suicide-related outcomes in adolescents: a systematic review.

Suicide-related outcomes among adolescents have become a serious public health problem worldwide. Emerging evidence suggests that sports participation may interact with suicide-related outcomes. The objective of this systematic review is to systematically review and summarize the association between sports participation and suicide-related outcomes among adolescents. A systematic review according to PRISMA Statement (International Platform of Registered Systematic Review and Meta-Analysis Protocols registration: INPLASY202330072) https://inplasy.com/inplasy-2023-3-0072/. The literature search was conducted in three electronic databases: Web of Science, PubMed, and EBSCOhost. A total of 16 studies (12 cross-sectional studies, 4 prospective studies) met the inclusion criteria were evaluated. Strong consistent evidence was found for the negative association between suicidal ideation, suicide attempts, and sports participation among adolescents. There was insufficient evidence to support consistency in the association between sports participation and suicide plans, and no evidence regarding gender differences between sports participation and these suicide-related outcomes. Furthermore, there was heterogeneity in the measures of sports participation and suicide-related outcomes across the included studies. Evidence suggests that more sports participations are associated with lower suicidal ideation and suicide attempts in adolescents. However, the directionality of the observed associations should be examined based on more high-quality longitudinal studies in the future.

Higher levels of plasma Adrenocorticotropic hormone (ACTH) are associated with lower suicidal ideation in depressed patients compared to controls and suicide attempters, independently from depression severity

IntroductionSuicidal ideation, an important risk factor for suicide attempts, has an unclear neurobiological basis and is potentially linked to the dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis and immune-inflammatory systems. While inflammatory markers have been associated with suicide attempts and, to a lower extent suicidal ideation, the data on the role of a stress-response system is less robust, with most studies carried out with cortisol showing inconsistent results. The present study extends on the previous studies implicating stress-response and immune-inflammatory systems in suicidal thoughts and behaviours, focusing on the associations of several stress-response (adrenocorticotropic hormone (ACTH), cortisol, and dehydroepiandrosterone (DHEA)) and immune-inflammatory (C-reactive protein (CRP),interle ukin-6 (IL-6), and tumour necrosis factor-alpha (TNF-alpha)) with suicidal ideation severity in recent suicide attempters, patients with major depressive disorder, and non-psychiatric controls. MethodsThis observational study included 156 adults from three Vilnius hospitals, recruited into one of the three groups in equal parts: recent suicide attempters, patients with major depressive disorder in current depressive episode, and non-psychiatric controls. Measures included the Hamilton Depression Rating Scale (HDRS-17) and the Beck Scale for Suicide Ideation/Suicide Severity Index (BSS/SSI), alongside sociodemographic data, alcohol, tobacco use, and morning blood samples, measuring plasma ACTH, cortisol, DHEA, CRP, and IL-6. Data were analysed with non-parametric tests, Kendall's tau correlation, and multivariate linear regression adjusted for confounders. ResultsWe found a negative correlation between the plasma ACTH levels and suicidal ideation severity (tau = −0.130, p = 0.033), which was driven by the patients with major depressive disorder (tau = −0.237, p = 0.031). Suicidal ideation severity was also negatively correlated with TNF-alpha (tau = −0.231; p < 0.001), positively correlated with IL-6 (tau = 0.154, p = 0.015), and CRP levels (tau = 0.153, p = 0.015), but no differences were observed in group-stratified analyses. The association between plasma ACTH levels and suicidal ideation severity in patients with major depressive disorder remained robust to adjustment for major confounders (adjusted for age, sex, education years, body mass index, smoking status, plasma CRP and PEth concentration (measuring chronic alcohol exposure), and antidepressant use) in the linear regression model (t = −2.71, p = 0.011), as well as additionally adjusting for depression severity (t = −2.99, p = 0.006). DiscussionThe present study shows an association between plasma ACTH levels and suicidal ideation severity in patients with major depressive disorder, robust to adjustment for antidepressant use and depression severity. This finding highlights the potential role of ACTH, in elucidating the effects of stress and mental health disorders. Our findings underscore the importance of the HPA axis in the diagnosis and treatment of suicidal ideation in major depressive disorder and invite further research on interventions targeting this pathway.

Person-centered approach to suicide ideation in posttraumatic stress disorder in veterans: a latent profile analysis

IntroductionWhile most research on suicidal ideation (SI) in veterans adopts a variable-oriented perspective, this approach often fails to capture the complex interplay of symptoms and comorbid disorders. We hypothesised that a person-centred approach can identify distinct subpopulations of veterans with varying profiles of SI, PTSD symptoms, depression, and agitation.ObjectivesTo examine whether distinct subpopulations of veterans exists, characterized by different profiles of PTSD severity, depression and agitation, and intensity of SI.MethodsWe conducted a cross-sectional study in one big University Hospital Centre in Croatia on the sample of men, war veterans aged 30-65 years, undergoing treatment for chronic PTSD. Latent profiles indicators included the Clinician-Administered PTSD Scale (CAPS), Beck Scale for Suicide Ideation (SSI), Hamilton Depression Rating Scale-17 (HDRS-17) and Corrigan Agitated Behaviour Scale (CABS).Results We included 203 male participants with a median age of 47 (IQR 43-45) years. The optimal model, allowing variances of indicators to vary between profiles while constraining covariances to zero, yielded five distinct latent profiles. Notably, the highest SI was found in a subpopulation with elevated CABS scores, but moderate PTSD and depression symptoms (13% of participants). Next in SI intensity were 11% of veterans with severe symptoms across all assessed disorders. Next in SI severity were 21% of veterans with low levels of agitation but high levels of depression. The last two profiles, one with mild symptoms of all assessed disorders (43%) and the other with high agitation (12%), have low SI severity.ConclusionsOur findings affirm the utility of a person-centred approach in identifying nuanced subpopulations of veterans with diverse symptom profiles related to SI.

Co-developmental trajectories of suicidal ideation and non-suicidal self-injury among Chinese adolescents: Transdiagnostic predictors and association with suicide attempts.

Adolescent suicidal ideation (SI) and non-suicidal self-injury (NSSI) are crucial public health issues, yet their co-developmental trajectories during early adolescence and their associations with predictors and outcomes are unclear. This study aimed to (a) identify heterogeneous co-developmental trajectories of SI and NSSI, (b) explore associations between transdiagnostic predictors and trajectories, and (c) assess suicide attempt risk across trajectories. Four hundred fifty-three adolescents (Mage = 12.35 years, 48.3% boys) completed surveys at 6-month intervals across 2 years. At Time 1 (Nov 2020), participants completed surveys encompassing SI, and NSSI, along with family, peer, and individual predictors. Subsequent surveys (Times 2-4) measured SI and NSSI, with suicide attempts queried at Time 4. Parallel process latent class growth models revealed three co-developmental groups (i.e., Stable low NSSI and SI; Moderate-NSSI and high-SI, parallel decreasing; High-NSSI and moderate-SI, parallel increasing). Multivariate logistic regression indicated that group membership was predicted by parental rejection, parental warmth, bullying victimization, depressive and anxiety symptoms, thwarted belongingness, and perceived burdensomeness. Adolescents in the "High-NSSI and moderate-SI, parallel increasing" group reported the highest suicide attempt frequency. These findings underscore subgroup distinctions and transdiagnostic predictors in comprehending SI and NSSI progression, emphasizing the necessity of dynamic monitoring and tailored interventions for distinct subgroup characteristics.

Examining optimism and flourishing as protective factors of suicidality across the adult lifespan: A cross-sectional investigation in three Spanish age groups

We examined optimism and flourishing as unique protective predictors of suicidality (viz., suicidal ideation and suicidal behaviors) in a cross-sectional study of young adults (18–35 years), middle-aged adults (36–55 years), and older adults (≥56 years). Young adults were found to have higher levels of suicidal ideation and suicidal behaviors compared to middle-aged and older adults. Controlling for depressive symptoms, the results of conducting regression analyses consistently implicated flourishing as a distinct predictor of lower suicidal ideation and suicidal behaviors in young adults and middle-aged adults. However, for older adults, only optimism was found to be a unique predictor of lower suicidal ideation and suicidal behaviors. Implications of the present findings for understanding the differential role of optimism and flourishing in accounting for suicidality across the adult lifespan are discussed.

Academic Resilience, Psychological Well-Being and Suicidal Ideation among Medical and Non-Medical Students

Background: The mental health of students in higher education, particularly concerning suicidal ideation, has been an area of growing concern. Academic resilience and psychological well-being are key factors that influence students' mental health. Understanding the relationship between these factors is crucial for developing effective interventions. Objective: This study aimed to explore the relationship between academic resilience, psychological well-being, and suicidal ideation among medical and non-medical students. The study sought to determine whether academic resilience serves as a protective factor against suicidal thoughts and how it interacts with psychological well-being. Methods: A cross-sectional survey was conducted with a sample of 200 students, evenly divided between genders and educational backgrounds (medical and non-medical). The study employed the Academic Resilience Scale, the Psychological Well-Being Scale, and the Suicidal Ideation Scale. Participants' ages ranged from 18 to 25 years, with an average age of 21.35 years. Statistical analyses included correlation, regression, and t-tests, using tools like SPSS version 25 for data processing. Results: The results indicated a positive correlation between academic resilience and psychological well-being (r=0.242, p&lt;0.01). Regression analysis showed that academic resilience (β=-0.59, p&lt;0.000) and psychological well-being (β=0.49, p&lt;0.000) were significant predictors of suicidal ideation. Medical students demonstrated higher academic resilience and lower suicidal ideation compared to non-medical students. Suicidal ideation scores among non-medical students were notably higher (Mean=125.63, SD=20.07) than medical students (Mean=107.30, SD=29.86). Conclusion: Academic resilience plays a crucial role in reducing suicidal ideation among students. Enhancing academic resilience, particularly among non-medical students, could be a key strategy in mitigating the risk of suicidal thoughts. This study highlights the importance of incorporating resilience-building initiatives in educational settings to improve student mental health.

VIOLENCE, IDENTITY, BEHAVIORS, AND ACCESS: MECHANISMS ACCOUNTING FOR CHANGES IN HEALTH OVER TIME OF LGBTQ OLDER ADULTS

Abstract As the population of older adults is growing in complexity and diversity, research has established health disparities by sexual and gender identity among older adults. While most research to date has been cross-sectional, this paper utilizes four-wave longitudinal data from Aging with Pride: National Health, Aging and Sexuality/Gender Study (NHAS) to understand the health and quality of life (QOL) of LGBTQ and sexual and gender diverse older adults over time. Mixed models were run to examine: (1) linear changes over time in health and QOL, controlling for background characteristics, (2) effects of key risk and protective factors on these changes, and (3) gender and age group interactions. Increases in violence, discrimination, identity stigma, adverse health behaviors and experiences (e.g., low physical activity, insufficient nutrition, and suicidal ideation), and decreased access to health and care services were related to poorer health, more cognitive and functional impairment, and lower QOL. Men (vs. women) and the Pride (vs. Silenced and Invisible) Generation were impacted to a greater degree by violence and discrimination, and the impacts of insufficient nutrition and suicidal ideation were also greater in the Pride Generation. Cognitive health of men and gender diverse individuals benefited more strongly from healthcare access. This longitudinal study provides important new findings regarding the mechanisms accounting for the accelerated decline in health and QOL over time in these diverse populations. This information is needed to develop tailored interventions that address these mechanisms as well as are responsive to variations among diverse ages, genders, and sexualities.
