RESUMO
BACKGROUND: Existing evidence suggests that children and adolescents who had experienced childhood maltreatment (CM) are at higher suicidal risk. However, the mediation role of resilience in this association remains unclear. We aim to investigate the mediation via resilience in the associations between CM and three suicidal risk indicators (suicidal ideation, SI; suicidal plan, SP; suicidal attempt, SA) among a large sample of Chinese children and adolescents. METHODS: A population-based cross-sectional survey was conducted in southwestern China Yunnan province. A total of 9723 children and adolescents were included and analyzed by using a multi-stage stratified cluster sampling design. Univariate and multivariate logistic regression models were fitted to explore the associations between CM, resilience, and the three suicidal risk indicators, dose-response trends further elucidated by using the restricted cubic splines. Path models were adopted to estimate the mediation of resilience. RESULTS: The estimated prevalence rates for one-year SI, SP and SA were 32.86% (95% CI: 31.93-33.80%), 19.36% (95% CI: 18.57-20.16%) and 9.07% (95% CI: 8.51-9.66%). After adjustment, CM significantly associated with all 3 suicidal risk indicators, and the odds ratios (ORs) were 2.13 (95% CI: 1.91-2.37), 2.45 (95% CI: 2.13-2.81), and 3.61 (95% CI: 2.90-4.52) for one-year SI, SP, and SA, respectively. Path models revealed that resilience significantly mediated the associations between CM and the three suicidal risk indicators, and among all dimensions of resilience, family support presented the strongest mediation consistently. CONCLUSIONS: Our study results suggest that intervention measures which focusing on improving psychological resilience might be effective in reducing suicidal risk for children and adolescents who had experienced maltreatment. Prospective studies should be done to corroborate our findings.

BACKGROUND: Despite a plethora of research on the topic, there is still no solid evidence that pharmacological treatment actually reduces the risk of suicide in patients with mental illness. In this study, we aimed to assess the effect of psychotropic medications on suicidal ideation in patients with major depressive disorder (MDD) and bipolar disorder (BPD) in two age groups: less than 25 years and 25 years and older. METHODS: We analyzed 312 patients with mood disorders with current suicidal thoughts or recent suicide attempts. We followed the participants from baseline for 6 months and assessed changes in suicidal ideation with Columbia-Suicide Severity Rating Scale (C-SSRS). The effect of psychotropic drug administration on suicidal ideation over time was analyzed using a linear mixed model. RESULTS: In patients aged 25 years and older with mood disorders, suicidal ideation was more severe when using psychotropic drugs than when not using them. However, suicidal ideation decreased rapidly over time. The time-dependent reduction in suicidal ideation was accelerated when using antidepressants and sedatives/hypnotics in adult MDD, and when using mood stabilizers in adult BPD. However, this effect was not observed in participants aged less than 25 years. CONCLUSION: Adequate psychotropic medication may reduce suicidal ideation in patients with mood disorders aged 25 years and older. Additional research on psychotropic drugs is needed to effectively reduce the risk of suicide among children and adolescents with mood disorders.

High-quality clinical care and research on suicidal thoughts and behaviors (STBs) depends on availability and implementation of reliable and valid measures of STBs. In contrast to studies examining STB risk factors, screening instruments, or treatment, little research has rigorously examined the content, characteristics, and psychometric properties of STB measures themselves. This systematic review (1) identified STB measures that conform to empirically supported definitions of STBs, and (2) identified peer-reviewed papers reporting on the psychometric properties of these measures in adults. Data on psychometric properties and other measure characteristics were extracted. A total of 21 eligible measures were identified in the first stage. In the second stage, 70 articles (with 79 independent samples) were included with psychometric data in adult samples for 19 measures. Although there was support for strong internal consistency and content validity across many measures, face validity and clinical utility concerns were prevalent. Few measures comprehensively assessed suicidal behaviors, and interview-based assessments tended to show the strongest psychometric properties and clinical utility. Findings are discussed in the context of recommendations for improving existing measures, including future research to increase utility and translatability across clinical settings, delivery methods, and diverse populations.

INTRODUCTION: Suicide is a severe public health problem. Impacts of childhood traumas, unsecure adult attachment styles and personality traits have been suggested as possible risk factors for suicide attempts. The aim of this cross-sectional, case-controlled study is to investigate the impact of childhood traumas, adult attachment styles and personality traits on suicide attempt. METHODS: The sample consisted of psychiatric patients who attempted suicide (n=101) on the one hand and those who did not attempt suicide (n=114) on the other. The questionnaires used were the Hungarian validated versions of Adult Attachment Scale (AAS), Childhood Trauma Questionnaire (CTQ), Temperament and Character Inventory (TCI) and a demographic questionnaire. RESULTS: Results indicated that Novelty Seeking (NS) temperament trait [EH=1.043; 95% C.I.=(0.950-1.145)] p=0.376; emotional abuse [EH=1.034; 95% C.I.=(0.966-1.107)] p=0.336; emotional neglect [EH=1.022; 95% C.I.=(0.936-1.116)] p=0.626; and sexual abuse [EH=1.047; 95% C.I.=(0.959-1.142)] p=0.305 were associated with nonsignificant increases in the odds of suicide attempts. Whereas secure attachment style [EH=0.908; 95% C.I.=(0.842-0.980)] p=0.013 appeared to be a significantly protective factor (c2(1)=6.515 p=0.011). Furthermore, when examining the connection between childhood traumas and adult attachment styles it was found that the anxious attachment style had a positive significant correlation with emotional abuse (rs(197)=0.293) p<0.001, avoidant attachment style with emotional neglect (rs(197)= 0.273) p<0.001. CONCLUSION: Our findings suggest that individuals with avoidant attachment style and childhood traumas are likely to present a higher suicide risk. However secure attachment style likely to present a lower risk for suicide.

BACKGROUND: The pandemic caused by the SARS-CoV-2 virus led to a series of containment and mitigation measures through lockdowns, social distancing, and the closure of educational establishments, which have had a profound impact on the mental health of the adolescent population. OBJECTIVE: The main objective of the present study has been to identify the sociodemographic and mental health variables related to suicidal ideation, planning, and attempts in young people participating in outpatient intervention projects within the Chilean protection network since the onset of the pandemic and the strictest lockdowns. METHOD: The study's sample consists of 125 young people aged 14 to 18 years (M = 15.65; SD = 1.22), participating in outpatient intervention projects within the National Service for Minors (SENAME)/Better Childhood protection network. Through a self-report survey, the young participants provided responses on sociodemographic variables and suicidal behaviour (ideation, planning, and attempts). RESULTS: 29.9% of the participants reported suicidal ideation during the onset of the pandemic and the established lockdowns; 29.2% reported having devised a plan to do so, and 18.2% indicated having attempted suicide during the evaluated period. A higher occurrence of suicidal behaviour was observed in females, sexual minorities, respondents over 15 years old, and respondents presenting depressive symptoms. CONCLUSIONS: The Covid-19 pandemic has had a significant impact on suicidal behaviour among the adolescent population served by the protection network in Chile. The prior violation of their rights may have contributed to the issue, particularly affecting young females in late adolescence with indicators of depression, who require specialized intervention due to the high risk detected.

Suicide among the older population is a significant public health concern in South Korea. As the older individuals have long considered suicide before committing suicide trials, it is important to analyze the suicidal ideation that precedes the suicide attempt for intervention. In this study, six machine learning algorithms were employed to construct a predictive model for suicidal thinking and identify key variables. A traditional logistic regression analysis was supplementarily conducted to test the robustness of the results of machine learning. All analyses were conducted using a hierarchical approach to compare the model fit of each model in both machine learning and logistic regression. Three models were established for analysis. In Model 1, socioeconomic, residential, and health behavioral factors were incorporated. Model 2 expanded upon Model 1 by integrating physical health status, and Model 3 further incorporated mental health conditions. The results indicated that the gradient boosting algorithm outperformed the other machine learning techniques. Furthermore, the household income quintile was the most important feature in Model 1, followed by subjective health status, oral health, and exercise ability in Model 2, and anxiety and depression in Model 3. These results correspond to those of the hierarchical logistic regression. Notably, economic and residential vulnerabilities are significant factors in the mental health of the older population with higher instances of suicidal thoughts. This hierarchical approach could reveal the potential target population for suicide interventions.

Enhancing social support and connectedness can reduce suicide risk, yet few studies have examined this effect in American Indian and Alaska Native (AI/AN) adults. We assessed suicidal ideation and behavior, thwarted belongingness, social support, enculturation, historical trauma, and traumatic life events in 709 AI/AN adults at high risk of suicide from five AI/AN communities. Suicidal ideation was associated with thwarted belongingness and protected against by social support and engaging in AI/AN ceremonies. Among those who made lifetime suicide attempts, traumatic life events, symptoms of depression/anxiety due to historical trauma, and thwarted belongingness were linked to more attempts. More engagement in cultural practices was associated with fewer suicide attempts. Higher levels of social support were associated with more suicide attempts, an observation potentially attributable to the cross-sectional nature of the study. Interventions should focus on protective factors and context-specific interventions emphasizing community history, values, and strengths.

The prevention paradox describes circumstances in which the majority of cases with a suicide attempt come from a population of low or moderate risk, and only a few from a 'high-risk' group. The assumption is that a low base rate in combination with multiple causes makes it impossible to identify a high-risk group with all suicide attempts. The best way to study events such as first-time suicide attempts and their causes is to collect event history data. Administrative registers were used to identify a group at higher risk of suicidal behaviour within a population of six national birth cohorts (N = 300,000) born between 1980 and 1985 and followed from age 15 to 29 years. Estimation of risk parameters is based on the discrete-time logistic odds-ratio model. Lifetime prevalence was 4.5% for first-time suicide attempts. Family background and family child-rearing factors were predicative of later first-time suicide attempts. A young person's diagnosis with psychiatric or neurodevelopmental disorders (ADHD, anxiety, depression, PTSD), and being a victim of violence or sex offences contributed to the explanatory model. Contrary to the prevention paradox, results suggest that it is possible to identify a discrete high-risk group (<12%) among the population from whom two thirds of all first-time suicide attempts occur, but one third of observed suicide attempts derived from low- to moderate-risk groups. Findings confirm the need for a combined strategy of universal, targeted and indicated prevention approaches in policy development and in strategic and practice responses, and some promising prevention strategies are presented.

PURPOSE: High rates of suicide and self-harm are reported in prisons in Western countries, while fewer studies exist from a non-Western context. This study aims to identify rates of suicide, non-fatal suicide attempts and self-harm in Moroccan prisons and to better understand the context, methods, tools, predictors and profile of persons engaged in the acts. DESIGN/METHODOLOGY/APPROACH: The authors report findings from a mixed-methods study carried out before an intervention project. The study consists of a systematic literature review, an analysis of suicide case files, a quantitative survey on suicide attempts and self-harm, as well as interviews and focus group discussions. The authors calculate suicide, suicide attempt and self-harm rates and present descriptive data on the incidents. The authors use regression models to explore the association between the number of incidents per individual and selected predictors, adjusting for clustering by institution. FINDINGS: Over a four-year period, 29 detained persons in Morocco died by suicide (average annual suicide rate 8.7 per 100,000). Most were men under the age of 30. Hanging accounted for all but one case. In one year, 230 suicide attempts were reported. Over a three-months period, 110 self-harm cases were reported from 18 institutions, cutting being the most common method. Self-harm was significantly more prevalent among persons with a life sentence or repeated incarcerations. RESEARCH LIMITATIONS/IMPLICATIONS: To make the study manageable as part of an intervention project, the authors collected data on suicides and suicide attempts from all prisons, while data on self-harm were collected from fewer prisons and over a shorter time period. The authors did not collect comparable information from detained persons who did not die by suicide, attempt suicide or self-harm. This prevented comparative analyses. Further, it is possible that self-harm cases were not reported if they did not result in serious physical injury. Data were collected by prison staff; thus, the voice of incarcerated persons is absent. PRACTICAL IMPLICATIONS: This study provided a solid basis for designing an intervention project including the development of a national prison policy and guidelines on suicides, suicide attempts and self-harm and a country-wide training program for prison staff. It also led to a better surveillance system, allowing for trend analysis and better-informed policymaking. The qualitative results helped create an understanding of how staff may trivialize self-harm. This was integrated into the training package for staff, resulting in the creation of prison staff trainers who became the strongest advocates against the notion that self-harm was best ignored. ORIGINALITY/VALUE: To the best of the authors' knowledge, this is the first published data on suicide and self-harm in Moroccan prisons. It underscores the necessity for the intervention project and gives valuable insights into suicide and self-harm in a non-Western prison context. Further research is needed to assess whether the findings are typical of the region.

BACKGROUND: Participants in research trials often disclose severe depression symptoms, including thoughts of self-harm and suicidal ideation, in validated self-administered questionnaires such as the Patient Health Questionnaire (PHQ-9). However, there is no standard protocol for responding to such disclosure, and the opportunity to support people at risk is potentially missed. We developed and evaluated a risk assessment protocol for the IBD-BOOST randomised controlled trial (ISRCTN71618461 09/09/2019). METHODS: Participants completed the PHQ-9 at baseline and 6-month and 12-month follow-ups. The trial database automatically alerted the research team to risk assess participants. Trial researchers, trained in the protocol, contacted participants by telephone, completed the risk assessment, and signposted participants to appropriate professional services. RESULTS: Seven hundred eighty participants were randomised in the trial; 41 required risk assessment. One participant declined assessment, so 40 risk assessments were completed. Twenty-four participants were assessed as low-risk and 16 participants as medium-risk, with 12 declaring previous suicide attempts. None were rated as high-risk. Trial participants expressed appreciation for being contacted, and all except two wished to receive information about professional support services. Trial risk assessors reported positive experiences of conducting the risk assessment with suggestions for improvement, which resulted in minor modifications to the protocol. DISCUSSION: Our evaluation demonstrated that it was viable for a research trial team to successfully conduct a risk-assessment protocol for trial participants reporting thoughts of self-harm, with training and support from senior colleagues. Resources are required for training and delivery, but it is not unduly onerous. Trial participants appeared to find completing the assessment acceptable.

Identifying phenotypes at high risk of suicidal behaviour is a relevant objective of clinical and translational research and can facilitate the identification of possible candidate biomarkers. We probed the potential association and eventual stability of neuropsychological profiles and serum BDNF concentrations with lifetime suicide ideation and attempts (LSI and LSA, respectively) in individuals with schizophrenia (SCZ) and schizoaffective disorder (SCA) in a 2-year follow-up study. A secondary analysis was conducted on a convenience sample of previously recruited subjects from a single outpatient clinic. Retrospectively assessed LSI and LSA were recorded by analysing the available longitudinal clinical health records. LSI + LSA subjects consistently exhibited lower PANSS-defined negative symptoms and better performance in the BACS-letter fluency subtask. There was no significant association between BDNF levels and either LSI or LSA. We found a relatively stable pattern of lower negative symptoms over two years among patients with LSI and LSA. No significant difference in serum BDNF concentrations was detected. The translational viability of using neuropsychological profiles as a possible avenue for the identification of populations at risk for suicide behaviours rather than the categorical diagnosis represents a promising option but requires further confirmation.

This study explored the relationship between variables emphasized in the theory's first step of the three-step theory (3ST)-psychache, hopelessness, and their interaction-to suicide-related variables (i.e., lifetime suicidal ideation and attempt, past-year suicidal ideation, communication of suicidal thoughts, and self-reported future suicide attempt likelihood). Chinese undergraduate students (N = 11,399; mean age = 20.69 ± 1.35) from seven provinces participated in this cross-sectional survey. They answered the Suicidal Behaviors Questionnaire-Revised, Psychache Scale, and Beck Hopelessness Scale. Bivariate and multivariate analyses were used to examine the association between psychache, hopelessness, and hopelessness × psychache interaction on the outcome variables. Bivariate analyses showed that psychache and hopelessness were correlated with suicidal ideation and behaviors. In multiple regression models, the interaction between psychache and hopelessness was significantly associated with past-year suicidal ideation and self-report chances of a future suicide attempt, p < 0.001, though effect sizes for the interaction term were small. The results are broadly consistent with the 3ST's proposition of how the combination of pain and hopelessness is related to various suicide-related variables. The low prevalence of suicide-related communication should inform future suicide prevention measures by encouraging help-seeking. Psychache as a correlate of the self-reported likelihood of a future attempt could be further investigated.

Suicidal behavior and demand for services have been increasing in adolescents. Many of the current treatments are focused on symptom mitigation, crisis management, and safety planning; however, few are aimed at remediating underlying vulnerabilities that may be contributing to suicide risk. Dynamic Deconstructive Psychotherapy (DDP) has been found to be effective for suicidal adults but has never been studied for adolescents. The present study examined real-world outcomes of 65 suicidal adolescents, aged 13-17 years, receiving weekly DDP in an outpatient clinic. The primary outcome was change in suicide ideation from baseline to 6 months of treatment as assessed by the Suicide Ideation Subscale of the Columbia Suicide Severity Rating Scale. In intent-to-treat analyses, suicide ideation significantly decreased over the 6 months with a large treatment effect (d = 1.19). Secondary measures, such as suicide attempts, self-harm, depression, anxiety, disability, self-compassion, and inpatient utilization, also improved significantly. Among the 42 adolescents (65%) who completed at least 6 months of treatment, suicide attempts decreased by 84%. DDP may be effective in reducing suicide ideation and other risk factors in suicidal adolescents and may be cost-effective given reduced inpatient utilization. These initial promising findings warrant further research and development.

INTRODUCTION: Adjustment disorder (AD) is a common psychiatric diagnosis, but it is often considered less severe than other diagnoses. However, it is strongly associated with suicidal behavior. AIM: To identify the factors linked to suicidal behavior in patients hospitalized for AD. METHODS: This is a retrospective, descriptive, and analytical study conducted in the psychiatric department of Mahdia's hospital over a period of nine years. The study included patients who were hospitalized for the first time due to adjustment disorder, according to DSM-5 diagnostic criteria. RESULTS: The study population included 129 patients. AD was prevalent among young (median age 29 years) and female patients (75.2%). Almost half of the cases were single (48.1%) and having a history of suicidal behavior (48.3%). Sixty patients (46.5%) were hospitalized following a suicidal attempt (SA) and drugs were used as a way in half of the cases (50%). Conflicts were the dominant factor precipitating the SA in 88.3% of cases. Factors linked to suicidal behavior in patients with AD were being in an intimate relationship and the presence of family conflicts. Indeed, the risk of suicidal behavior was found to be increased by 3.15 times in patients with AD who experienced family conflicts. Besides, being in an intimate relationship in patients with AD multiplies the risk of suicidal behavior by 5.863. CONCLUSIONS: Given the high risk of suicide associated with AD, it is essential to have a more in-depth understanding of the suicidal process and AD through new studies.

Machine Learning models trained from real-world data have demonstrated promise in predicting suicide attempts in adolescents. However, their transportability, namely the performance of a model trained on one dataset and applied to different data, is largely unknown, hindering the clinical adoption of these models. Here we developed different machine learning-based suicide prediction models based on real-world data collected in different contexts (inpatient, outpatient, and all encounters) with varying purposes (administrative claims and electronic health records), and compared their cross-data performance. The three datasets used were the All-Payer Claims Database in Connecticut, the Hospital Inpatient Discharge Database in Connecticut, and the Electronic Health Records data provided by the Kansas Health Information Network. We included 285,320 patients among whom we identified 3389 (1.2%) suicide attempters and 66% of the suicide attempters were female. Different machine learning models were evaluated on source datasets where models were trained and then applied to target datasets. More complex models, particularly deep long short-term memory neural network models, did not outperform simpler regularized logistic regression models in terms of both local and transported performance. Transported models exhibited varying performance, showing drops or even improvements compared to their source performance. While they can achieve satisfactory transported performance, they are usually upper-bounded by the best performance of locally developed models, and they can identify additional new cases in target data. Our study uncovers complex transportability patterns and could facilitate the development of suicide prediction models with better performance and generalizability.

BACKGROUND: Evidence suggests that having a chronic physical illness (CPI; eg, asthma, diabetes, and epilepsy) is an independent risk factor for suicidality (ie, suicidal ideation or attempts) among youth. Less is known about the mechanisms linking CPI and suicidality. Some evidence suggests that mental illness (eg, depression and anxiety) or neurodevelopmental disorder (eg, attention-deficit/hyperactivity disorder) mediates or moderates the CPI-suicidality association. Missing from the knowledge base is information on the association between having co-occurring CPI and mental illness or neurodevelopmental disorder (MIND) on youth suicidality. OBJECTIVE: This study uses epidemiological data from the 2019 Canadian Health Survey of Children and Youth (CHSCY) to study the intersection of CPI, MIND, and suicidality in youth. We will estimate prevalence, identify predictors, and investigate psychosocial and service use outcomes for youth with CPI-MIND comorbidity versus other morbidity groups (ie, healthy, CPI only, and MIND only). METHODS: Conducted by Statistics Canada, the CHSCY collected data from 47,850 children (aged 1-17 years) and their primary caregiving parent. Measures of youth CPI, MIND, family environment, and sociodemographics are available using youth and parent informants. Information on psychiatric services use is available via parent report and linkage to national administrative health data found in the National Ambulatory Care Reporting System and the Discharge Abstract Database, which allow the investigation of hospital-based mental health services (eg, emergency department visits, hospitalizations, and length of stay in hospital). Questions about suicidality were restricted to youths aged 15-17 years (n=6950), which form our analytic sample. Weighted regression-based analyses will account for the complex survey design. RESULTS: Our study began in November 2023, funded by the American Foundation for Suicide Prevention (SRG-0-008-22). Access to the linked CHSCY microdata file was granted in May 2024. Initial examination of CHSCY data shows that approximately 20% (1390/6950) of youth have CPI, 7% (490/6950) have MIND, 7% (490/6950) seriously considered suicide in the past year, and 3% (210/6950) had attempted suicide anytime during their life. CONCLUSIONS: Findings will provide estimates of suicidality among youth with CPI-MIND comorbidity, which will inform intervention planning to prevent loss of life in this vulnerable population. Modeling correlates of suicidality will advance understanding of the relative and joint effects of factors at multiple levels-information needed to target prevention efforts and services. Understanding patterns of psychiatric service use is vital to understanding access and barriers to services. This will inform whether use matches need, identifying opportunities to advise policy makers about upstream resources to prevent suicidality. Importantly, findings will provide robust baseline of information on the link between CPI-MIND comorbidity and suicidality in youth, which can be used by future studies to address questions related to the impact of the COVID-19 pandemic and associated countermeasures in this vulnerable population of youth.

BACKGROUND: Developing an understanding of the negative impact of discrimination is critical when examining the suicidality of Black young adults in the US. Suicide rates among Black young adults have increased at alarming rates. One of the reasons for this increase is the disparities related to access to mental health services, which has long-term health consequences. This study addresses a significant gap in the literature by examining associations between experiences of everyday discrimination, attitudes towards mental health help-seeking attitudes, on the outcomes suicide ideation, planning to die by suicide, and suicide attempts. METHODS: The data came from a national study of the experiences of Black young adults regarding mental, physical, and sexual health. Participants were recruited from across the Midwestern region of the United States through Qualtrics Panels, an online survey delivery service used to recruit study participants. The total sample for this study was N = 362, and the average age of the sample was 21 (SD: 1.96). We used a logistic regression analysis to examine the role of everyday discrimination, mental health support-seeking attitudes, and covariates on the outcomes: suicide ideation, planning to die by committing suicide, and suicide attempts. RESULTS: Black young adults with positive mental health help-seeking attitudes were 34% less likely to attempt suicide (OR = 0.66; 95% CI: 0.46, 0.96) and 35% less likely to experience suicide ideation (OR = 0.65; 95% CI: 0.47, 0.89). However, those young adults who experienced discrimination daily were more likely to report having attempted suicide (OR = 1.70; 95% CI: 1.34, 2.15). CONCLUSIONS: Our findings offer valuable insights into the complex interplay between experiences of discrimination, attitudes toward seeking mental health support, and suicidal behaviors. However, our research also underscores how experiences of discrimination can significantly exacerbate feelings of isolation, hopelessness, and inadequacy, further contributing to suicidal behaviors in this population. By promoting positive mental health help-seeking behaviors, actively addressing discrimination, and applying an intersectional approach to suicide prevention efforts, we can take significant strides towards building a more supportive and inclusive society. This approach aims to empower individuals to seek help, reduce the risk of suicidal behaviors, and create a more welcoming environment for all members of our community.
