Transitions in Suicide Risk from Early Adolescence to Early Adulthood

Objective Understanding patterns of suicide risk over the course of development can aid our ability to prevent suicide. Our community-based study examined changes in suicide risk status and predictors of changes in risk status in a sample of 521 adolescents over six assessments between the start of middle school and young adulthood (ages 12–22). Methods Suicidal thoughts and behaviors (STB) were measured with the Diagnostic Interview Schedule for Children and the Moods and Feelings Questionnaire. Latent transition analysis (LTA) was utilized to evaluate transitions in suicide risk status over the course of development. Nine risk factors’ initial values and change over time were modeled as predictors in the LTA. Results Latent class analysis identified a four-class model of developmental suicide risk patterns: Class 1: Infrequent STB (73–87% of participants), Class 2: Diminishing STB (1–17% of participants), Class 3: Escalating STB (6–16% of participants), and Class 4: Consistently High STB (1–5% of participants). LTA demonstrated that infrequent STB members and escalating STB members were likely to maintain their risk class across time points. Conclusions Classification of STB trajectories demonstrated self-worth and family involvement were salient variables affecting transitions in risk over time and suggest prevention targets early in adolescence that could have impact on suicide risk in adulthood.

Multi-modal risk factors differentiate suicide attempters from ideators in military veterans with major depressive disorder

BackgroundThe suicide rate for United States military veterans is 1.5× higher than that of non-veterans. To meaningfully advance suicide prevention efforts, research is needed to delineate factors that differentiate veterans with suicide attempt/s, particularly in high-risk groups, e.g., major depressive disorder (MDD), from those with suicidal ideation (no history of attempt/s). The current study aimed to identify clinical, neurocognitive, and neuroimaging variables that differentiate suicide-severity groups in veterans with MDD. MethodsSixty-eight veterans with a DSM-5 diagnosis of MDD, including those with no ideation or suicide attempt (N = 21; MDD-SI/SA), ideation-only (N = 17; MDD + SI), and one-or-more suicide attempts (N = 30; MDD + SA; aborted, interrupted, actual attempts), participated in this study. Participants underwent a structured diagnostic interview, neurocognitive assessment, and 3 T-structural/diffusion tensor magnetic-resonance-imaging (MRI). Multinomial logistic regression models were conducted to identify variables that differentiated groups with respect to the severity of suicidal behavior. ResultsRelative to veterans with MDD-SI/SA, those with MDD + SA had significantly higher left cingulum fractional anisotropy, decreased attentional control on emotional-Stroop, and faster response time with intact accuracy on Go/No-Go. Relative to MDD + SI, MDD + SA had higher left cingulum fractional anisotropy and faster response time with intact accuracy on Go/No-Go. LimitationsFindings are based on retrospective, cross-sectional data and cannot identify causal relationships. Also, a healthy control group was not included given the study's focus on differentiating suicide profiles in MDD. ConclusionsThis study suggests that MRI and neurocognition differentiate veterans with MDD along the suicide-risk spectrum and could inform suicide-risk stratification and prevention efforts in veterans and other vulnerable populations.

Role of sleep problem on suicidal behaviour and non-suicidal self-injury among adolescents in Pokhara, Nepal.

Sleep is a fundamental human requirement, considered one of the major contributing factors to physical and mental health, especially among adolescents. Poor quality sleep has many potential consequences including non-suicidal self-injury (NSSI), suicidal thoughts or behaviour and complete suicide. The NSSI and suicidal behaviour are increasing in Nepal. Thus, this study aimed to assess the role of sleep problem on suicidal behaviour and non-suicidal self-injury among adolescents in Pokhara metropolitan, Nepal. A cross-sectional analytical study was conducted among 673 adolescents using a multistage cluster sampling technique from private and public schools in Pokhara Metropolitan. Self-administered questionnaire was used for data collection. Collected data was entered and managed in EpiData (version 3.1) and analysed in IBM SPSS (version 23). Binary logistic regression was used to identify the association of sleep problem with NSSI and suicidal behaviour. The study found that sleep problem (65.2%, 439), suicidal behaviour (18.6%, 125) and NSSI (57.9%, 390) were prevalent among adolescents in study setting. The presence of sleep problem significantly influenced the suicidal behavior (AOR = 3.88, 95% CI = 2.27-6.63) alongside the sex of student (AOR = 1.96, 95% CI = 1.28-3.00), adolescents from family having monthly income less than NPR 40,000 (AOR = 1.97 95% CI = 1.16-3.35) and private schools students (AOR = 2.99, 95% CI = 1.84-4.86). Likewise, sleep problem was also associated with non-suicidal self-injury (AOR = 3.24, 95% CI = 2.26-4.65), in addition to attending private school (AOR = 2.52, 95% CI = 1.71-3.72). This study concludes that sleep problem is prevalent among the adolescents and increase the risk of NSSI and suicidal behaviour. Therefore, parents and teachers need to assess their conditions and help them maintain sound sleep. Additionally, suicide prevention strategies need to be adopted to mitigate further risk.

Undetected suicide attempts among U.S. soldiers: results from the Army Study to Assess Risk and Resilience in Servicemembers (Army STARRS).

While previous studies have reported high rates of documented suicide attempts (SAs) in the U.S. Army, the extent to which soldiers make SAs that are not identified in the healthcare system is unknown. Understanding undetected suicidal behavior is important in broadening prevention and intervention efforts. Representative survey of U.S. Regular Army enlisted soldiers (n = 24 475). Reported SAs during service were compared with SAs documented in administrative medical records. Logistic regression analyses examined sociodemographic characteristics differentiating soldiers with an undetected SA v. documented SA. Among those with an undetected SA, chi-square tests examined characteristics associated with receiving a mental health diagnosis (MH-Dx) prior to SA. Discrete-time survival analysis estimated risk of undetected SA by time in service. Prevalence of undetected SA (unweighted n = 259) was 1.3%. Annual incidence was 255.6 per 100 000 soldiers, suggesting one in three SAs are undetected. In multivariable analysis, rank ⩾E5 (OR = 3.1[95%CI 1.6-5.7]) was associated with increased odds of undetected v. documented SA. Females were more likely to have a MH-Dx prior to their undetected SA (Rao-Scott χ21 = 6.1, p = .01). Over one-fifth of undetected SAs resulted in at least moderate injury. Risk of undetected SA was greater during the first four years of service. Findings suggest that substantially more soldiers make SAs than indicated by estimates based on documented attempts. A sizable minority of undetected SAs result in significant injury. Soldiers reporting an undetected SA tend to be higher ranking than those with documented SAs. Undetected SAs require additional approaches to identifying individuals at risk.

The Association between Hyperactivity and Suicidal Behavior and Attempts among Children Referred from Emergency Departments.

The global prevalence of suicidal behaviors in children is rising, with attention-deficit hyperactivity disorder (ADHD) proposed as a contributing factor. This study examines the association between ADHD facets (hyperactivity and inattention) and suicidal behavior and attempts in children. Additionally, it seeks to compare self-reported ADHD symptoms and suicide-related incidents with parental reports. A cohort of 71 children referred from emergency departments due to suicidal thoughts and behaviors completed self- and parental report questionnaires. The results revealed that elevated hyperactivity scores, surpassing the ADHD diagnosis threshold, were significantly associated with increased rates of suicidal behavior. Hyperactivity demonstrated a stronger association with lifetime suicide attempts compared to inattention. Moreover, children's self-reported ADHD symptoms exhibited a stronger correlation with suicide attempts than parental reports. This study highlights the critical role of hyperactivity in understanding suicidal behaviors among children with ADHD. It underscores the importance of considering hyperactivity-related symptoms in assessment and treatment approaches for suicidal behavior in this population.

Prediction of suicide attempt in a Swedish population-based cohort.

Suicidal behaviors are prevalent public health concerns, and we need to improve our predictive ability to better inform prevention efforts. Using nationwide longitudinal Swedish registers, we included 344,490 males and 323,177 females born 1982-1990 with information on genetic liability and environmental exposures from birth to age 16: perinatal variables, parental psychopathology (suicide attempt, substance use disorder, major depression), family status, socioeconomic difficulties, peers' psychopathology, and school grades. We conducted sex-specific analysis and developed data-driven predictive models including risk factors that occurred between ages 0 and 16 using structural equation modeling. In both females and males, the best-fitting models reveal a complex risk pathway to suicide attempt. In females, the model indicates four direct effects on suicide attempt risk: the occurrence of suicide attempt in parents during childhood (β = 0.159, 95% CI: 0.118; 0.199) and adolescence (β = 0.115, 95% CI: 0.077; 0.153), suicide attempt in peers (β = 0.068, 95% CI: 0.057; 0.079), and low academic achievement (β = 0.166, 95% CI: 0.156; 0.175). In males, aggregate genetic liability for suicide attempt (β = 0.130, 95% CI: 0.111; 0.148), suicide attempt in parents during adolescence (β = 0.099, 95% CI: 0.074; 0.124), suicide attempt in peers (β = 0.118, 95% CI: 0.108; 0.129), and low academic achievement (β = 0.61, 95% CI: 0.152; 0.171) were related to later suicide attempt. These factors also acted as mediators to explain the association between environmental exposures in childhood and later suicide attempt. These findings illustrate sex-specific pathways to suicide attempt by including risk factors that occur during the development. Results highlight the importance of genetic and family environment but also the prominent role of academic achievement.

Depression severity and verbal comprehension in children and adolescents with a major depressive episode.

Severe depression is a prevalent psychiatric illness in children and adolescents associated with high levels of morbidity, disability, and a high risk of suicidal behavior. Cognitive factors associated with depression severity in juveniles have been poorly reported. We investigated the relationship between depression severity and intelligence quotient (IQ)with its subscales in 65 juveniles (aged 10-17 years) with a current major depressive episode evaluated at the Mood Disorder Program of Bambino Gesù Children's Hospital in Rome. Pearson's correlation analyses were followed by a Benjamini-Hochberg correction and linear multivariable regression model. Depression severity measured with the total score of the Children's Depression Rating Scale-Revised (CDRS-R) was positively associated with the Verbal Comprehension Index (VCI; Pearson's r = 0.309 [0.042-0.534]; p = 0.024). The CDRS-R subscales positively associated with VCI by Pearson's correlation were depressed feelings, suicidal ideation, excessive weeping, and reduced facial expressions. Suicidal ideation was the only factor independently and significantly associated with higher VCI in the multivariable linear regression model. Suicidal ideation was significantly and independently associated with higher verbal comprehension, indicating that depressed juveniles with better verbal ability may be at a greater risk of showing suicidal ideation.

A systematic review on passive sensing for the prediction of suicidal thoughts and behaviors

Passive sensing data from smartphones and wearables may help improve the prediction of suicidal thoughts and behaviors (STB). In this systematic review, we explored the feasibility and predictive validity of passive sensing for STB. On June 24, 2024, we systematically searched Medline, Embase, Web of Science, PubMed, and PsycINFO. Studies were eligible if they investigated the association between STB and passive sensing, or the feasibility of passive sensing in this context. From 2107 unique records, we identified eleven prediction studies, ten feasibility studies, and seven protocols. Studies indicated generally lower model performance for passive compared to active data, with three out of four studies finding no incremental value. PROBAST ratings revealed major shortcomings in methodology and reporting. Studies suggested that passive sensing is feasible in high-risk populations. In conclusion, there is limited evidence on the predictive value of passive sensing for STB. We highlight important quality characteristics for future research.

Measuring psychache as a suicide risk variable: A Mokken analysis of the Holden's Psychache Scale

BackgroundThe Psychache Scale (PAS) is a questionnaire measuring trait-level psychological pain with satisfactory internal consistency and a strong correlation with suicidal ideation severity. However, inconsistent results have been reported for the PAS dimensionality. In the present study we used a non-parametric item response theory model, called Mokken Scale Analysis (MSA), to refine an unidimensional version of the PAS. MethodsThe sample was composed of 400 Italian adults (312 females and 88 males) nonrandomly recruited from the general population. ResultsA final set of 10 items satisfied the unidimensionality, local independence, and monotonicity assumptions, although it did not satisfy the double monotonicity assumption. The internal consistency of the PAS-10 was satisfactory (ordinal alpha = 0.98, ω = 0.97, and AVE = 0.82), and ROC curves analysis indicated good discriminant validity when differentiating participants with higher suicide risk from those with lower suicide risk. LimitationsStructural invariance between nonclinical and clinical samples was not investigated, and the presence of suicide ideation and behaviors was assessed with self-report measures with potential under-reporting of the phenomenon. ConclusionThe PAS-10 resulted to be a potentially valid and unidimensional measure of psychological pain (i.e., psychache) that could be used to screen adults at higher risk for suicide. Future studies are needed to investigate psychometric properties of the PAS-10 in clinical samples and to replicate results in independent samples.

The affective temperaments as a prognostic factor in the course of alcohol addiction – a key to enhance diagnoses and therapy?

The paper outlines the role of affective temperaments, as defined by Akiskal, in the development and maintenance of alcohol use disorders with a particular focus on the clinical course of addiction. Among affective temperaments, a cyclothymic temperament seems to play a key role in the development and maintenance of alcohol use disorders, and have the greatest influence on the clinical course of addiction. A high cyclothymic score is associated with inter alia an earlier onset of drinking and alcohol dependence, a negative course of alcohol dependence, relapse and alcohol craving. The structure of affective temperaments is also a predictor of suicidal behavior and drug addiction in the alcohol addict population. Interest has been growing regarding the role of affective temperament in the development and course of alcohol dependence; however, further research in this area is needed. An understanding of the temperamental determinants of alcohol dependence in the affective dimension may significantly support diagnostic and therapeutic procedures. Affective temperament profile may be suggestive of alcohol use disorders and may be a primary prognostic factor of craving and relapse, potential suicide, treatment motivation and the co-occurrence of drug dependence among patients with alcohol use disorder.

Suicidal Behavior and Personality Group Affiliation: Approaches and Research Directions

Introduction. As it follows from a number of scientific works, not only suicide rates, but also their motives and ways of committing suicide vary widely in different countries, strata of society and strata of the population. In recent decades, research on this issue has become interdisciplinary and cross-cultural. Suicidal behavior is increasingly considered in the context of the suicidal person’s belonging to a certain social group or cultural community. Objective. To analyze the impact of an individual’s membership in a large social group or cultural community on suicidal behavior. The main directions of suicidal behavior research. In the vast array of theoretical and research works the following directions of suicidal behavior study can be distinguished: existential, clinical, socio-demographic, socio-cultural and socio-psychological. Starting from E. Durkheim’s sociological etude “Suicide”, the group affiliation of an individual is considered as a leading factor of suicidal behavior. However, the sociological approach appears limited because its proponents place excessive emphasis on demographic variables rather than on the psychological significance of suicide and the values of the individual prone to suicidal behavior. A. Adler’s socio-psychological conceptualization of suicide is partly responsible for overcoming these limitations. Adler’s socio-psychological concept of suicide, which takes into account not only demographic indicators, but also how suicides perceive, evaluate and experience their own group affiliation and the values of their social group. According to A. Adler, the predictors of suicide are a sense of community (belonging) and social interests of the individual. Sense of community and group belonging as a factor of suicidal behavior. Comparison of studies conducted in three countries (Russia / USSR, Japan and the USA) allows us to identify two socio-psychological factors of suicidal behavior: 1) negative attitude to one’s own group or cultural identity; 2) hypertrophy of the sense of community and belonging, leading to a decrease in the value of one’s own personality and individual life. Discussion. As modern cross-cultural studies show, suicidal behavior can be observed both at the deficit of the sense of community and group belonging and at the high level of development of this sense. This is conditioned, on the one hand, by the attitude of a suicide victim to his/her social group and cultural identity, and, on the other hand, by the historically formed attitude of society to suicide.

Accessibility and Utility of an Electronic Self-Guided Safety Plan for Adolescents

ABSTRACT Objective Suicidal thoughts and behaviors are a leading cause of death, injury, and hospitalization among adolescents. Few evidence-based interventions exist, and these tend to be inaccessible for most youth. Electronic safety plan interventions represent a new avenue to disseminate an evidence-based suicide prevention tool. However, it is not clear whether youth find electronic, self-guided safety plans helpful, nor whether they will use the resulting safety card when experiencing suicidal thoughts or urges. This study examines adolescents’ perceptions and use of an electronic, self-guided safety plan intervention. Method We recruited 322 adolescents with a past-year history of suicidal thoughts or behaviors, ages 13–17 (55.9% white and non-Hispanic; majority reporting diverse sexual orientations and genders) online via social media to participate in this two-part longitudinal study. At baseline, participants completed the electronic safety plan interventions and reported on key aspects of its usefulness and areas of improvement. Participants reported their use and perceptions of the plan one month later. Results Results suggested that adolescents understood, liked, and believed they would use a self-guided safety plan. One month later, about ⅓ of youth who experienced suicidal thoughts or urges used their safety card. Open-ended responses highlighted several features that adolescents enjoyed, including clarity, ease of use, and privacy. Participants also highlighted key areas for improvement, including formatting and language. Conclusion This study provides initial support for adolescent use of electronic self-guided safety plans. Next steps include updating this intervention based on youth feedback and testing the effectiveness of this tool using gold standard research methods.

Utilization of Psychosocial Support for Young Adults with Suicidal Thoughts and Behaviors

The study explores the utilization of psychosocial support by young adults facing suicidal ideation or impulses, considering a comprehensive spectrum of psychosocial services. The study sheds light on help utilization and gaps in service use among different groups. The data is derived from the baseline assessment of the research project "Outcome Evaluation [U25]". The sample includes 888 young adults who reported suicidal thoughts and behaviors. Among the participants, 55% accessed at least one psychosocial service. Medical/psychotherapy services were the most utilized (54%), followed by professional counseling (34%) and non-professional self-help services (22%). Gender differences were observed, with males using help less frequently than females and individuals with diverse gender identities. Participants in relationships were less likely to seek help than singles. A migrant background showed no consistent impact on service utilization. Psychological distress and suicide literacy were associated with increased service utilization. Regression analysis revealed that gender and relationship status remained predictors of service utilization even when considering mental distress, suicidal thoughts and behaviors, and suicide literacy.

Means to an end: Characteristics and follow-up of emergency department patients with a history of suicide attempt via medication overdose.

Availability and accessibility of a wide range of medications may be a contributing factor to rising medication-related overdose (OD) rates. Treatment for both suicide attempts (SAs) and ODs often occurs in the emergency department (ED), highlighting its potential as a screening and intervention point. The current study aimed to identify sociodemographic and clinical characteristics of individuals who reported SA via medication OD compared to other methods and to examine how these patients' suicide severity and behaviors differed over 12-month post-ED follow-up. Data were analyzed from Phases 1 and 2 of the Emergency Department Safety Assessment and Follow-up Evaluation multicenter study (N = 1376). Participants with a history of SA (n = 987) were categorized based on whether they indicated a past medication-related SA via OD. Of participants with history of SA, 62.7% (n = 619) reported medication OD for either their most serious or their most recent SA. Multivariate analyses indicated female birth sex, diagnosis of bipolar disorder, and having some college education were significantly associated with membership in the medication OD attempt group (p <0.05). Of those who attempted suicide over the 12-month follow-up, nearly 60% of participants in the medication OD attempt group reported a subsequent SA via OD over follow-up. However, nearly half (46.5%) of participants with no medication OD at baseline also reported medication OD at follow-up. Among patients presenting to the ED, females, individuals with bipolar disorder, and patients with a college education, respectively, may be at highest risk for SAs via medication OD. Prospectively, medication OD appears to be a frequent method, even among individuals with no prior attempt via OD, as demonstrated by the high percentage of patients who did not have a medication OD at baseline, but reported a medication OD during follow-up.

The impact of the COVID-19 pandemic on presentations with suicidal behaviour in a tertiary hospital Emergency Centre in the Eastern Cape, South Africa–A cross-sectional analysis

IntroductionSuicidal behaviour is a public health emergency, causing an estimated one million deaths globally each year. The impact of the COVID-19 pandemic on suicidal behaviour is not fully understood. This study aimed to describe the impact of the COVID-19 pandemic on presentations with suicidal behaviour at a tertiary hospital in the Eastern Cape, South Africa. MethodThis study was a retrospective cross-sectional analysis of patients with fatal and nonfatal suicidal behaviour who presented to Frere Hospital Emergency Centre in the Eastern Cape, South Africa. The analysis included three study periods: August to October 2019 (pre-COVID-19), August to October 2020 (wave 1), and August to October 2021(wave 3). ResultsA total of 16 419 patients presented to the Frere Hospital Emergency Centre during the study period, with 6 204 in 2019, 4 909 in 2020, and 5 306 in 2021. These correspond to the research periods from August to October for each successive year. The overall prevalence of suicidal behaviour was 1.6 % but decreased marginally during the pandemic (1.8 % in 2019 vs. 1.4 % in 2021) – contrary to what occurred in high-income countries. The prevalence demonstrated a clinically insignificant stepwise decline as the pandemic progressed and was inversely associated with the number of daily new COVID-19 cases nationally. A significant increase in the emergency centre's total length of stay was however observed during the COVID-19 period (143 vs. 80 min, p < 0.001). The high proportion (66 %) of patients with suicidal behaviour requiring admissions increased further during the COVID-19 study period, placing an additional burden on inpatient disciplines. The proportion of social worker consultations increased significantly during the COVID-19 period (65% vs. 44 %, p<.05). ConclusionThe COVID-19 pandemic marginally reduced the prevalence of presentations with suicidal behaviour to the Emergency Centre, contrary to what was observed in high-income countries.

Genetic predisposition of suicidal behavior: variants in GRIN2B, GABRG2, and ODC1 genes in attempted and completed suicide in two Balkan populations

AbstractCompleted suicide accounts for over 700,000 deaths worldwide annually, while attempted suicide is 20 times more frequent. Genetic background is an important factor contributing to suicidal behavior, including candidate genes in glutamate, γ-aminobutyric acid (GABA), and polyamine systems. Our aim was to differentiate genetic predispositions underlying different types of suicidal behavior, attempted and completed suicide, in two Balkan populations. Analysis of variants in the genes GRIN2B (rs2268115 and rs220557), GABRG2 (rs424740), and ODC1 (rs1049500 and rs2302614) was performed on a study sample including 173 suicide attempters with comorbid psychiatric disorders, 216 non-suicidal psychiatric patients and 172 healthy controls from Serbia, and 333 suicide completers and 356 non-suicidal autopsy controls from Slovenia. CA genotype of rs220557 in GRIN2B gene increased the risk for completed suicide (P = 0.021), and violent suicide (P = 0.037), compared to controls. In ODC1 gene, CA genotype of rs2302614 decreased the risk for completed suicide compared to suicide attempt (P = 0.012). Marginally, AC haplotype for variants rs1049500-rs2302614 in ODC1 gene decreased the risk for completed suicide compared to suicide attempt (P = 0.052). Specific genetic variants of glutamate and polyamine systems are differently distributed among diverse suicidal phenotypes, providing further information on the implication of these systems in suicidality.

Cannabis, cannabinoids and health: a review of evidence on risks and medical benefits

AbstractThe legalization of cannabis for medical and recreational purposes has progressed internationally. Cannabis and cannabinoids are advocated for a plethora of medical indications. An increasing number of medical and nonmedical users regularly consume large doses of delta-9-Tetrahydrocannabinol (THC), the main active component of cannabis. Aim: to summarize the evidence on (1) risks of recreational cannabis use and (2) effectiveness and safety of medicinal cannabis. Findings on recreational use: Cannabis is mostly used to experience its acute rewarding effects. Regular use of high THC products can produce addiction (cannabis use disorder or CUD). Acute consumption of high THC doses (including unintentionally) can cause time-limited mental, gastrointestinal, and cardiovascular problems and motor vehicle accidents. Chronic patterns of cannabis use have been associated with multiple adverse outcomes that are of particular concern among adolescents and young adults, such as, disrupted learning, impaired cognitive performance, reduced educational attainment and an increased risk of CUD, psychosis/schizophrenia, mood and anxiety disorders and suicidal behaviors. There is debate about the extent to which cannabis use is a cause of these adverse outcomes. Physical health risks (e.g., respiratory and cardiovascular, prematurity and restricted fetal growth, hyperemesis syndrome among others) have also been linked with repeated consumption of cannabis with a high THC content. Findings on medical cannabis use: Herbal cannabis, medicines from extracted or synthetized cannabinoids—often used as adjuvants to standard medicines—may produce small to modest benefits. This is primarily the case in treating chronic pain, muscle spasticity, chemotherapy-induced nausea and vomiting, and refractory epilepsy (in the case of cannabidiol, CBD). The evidence is inconclusive on their value in treating mental disorders and other medical conditions. Safety: Cannabis-based medicine is generally well tolerated. There is a risk of mild to moderate adverse effects and CUD.

Development and validation of the Transgender Adolescent Stress Survey-Dysphoria.

Transgender and nonbinary adolescents (TNBA) may experience gender dysphoria arising from incongruities between their body and their gender. Prior dysphoria measures have largely focused on clinical diagnosis with little regard to comparability of forms for people assigned male or female at birth, overall psychometric performance, or applicability to nonbinary populations. This study develops and validates the Transgender Adolescent Stress Survey-Dysphoria (TASS-D), intended to address these gaps. The current study recruited a U.S. national sample of TNBA (N = 444, aged 12-17; 65.5% White, 9.5% Black, 9.5% Latine, 15.5% other ethnicity; 34.7% transmasculine, 17.3% transfeminine, 38.3% nonbinary, 9.5% agender). The item pool was developed from life history calendars, a modified Delphi process, and cognitive interviews with TNBA. Scale development included factor analysis, item response theory modeling, measurement invariance testing, and reliability analyses. Associations were examined between the TASS-D and existing measures of gender dysphoria (convergent validity), gender minority stress (divergent validity), and behavioral health outcomes (criterion validity). TASS-D and its subscales (body distress and gender expression burden) were significantly and strongly associated with gender dysphoria; significantly but weakly associated with gender minority stress; and significantly associated with most indicators of psychological distress including depressive, anxiety, and posttraumatic stress symptoms, suicidal behaviors and nonsuicidal self-injury. The TASS-D is a reliable and valid measure of gender dysphoria for TNBA, offering notable benefits over existing measures: It is psychometrically sound, inclusive of all gender identities, and does not assume that respondents identify binarily or desire medical transition as a terminal goal.

A REVIEW ON MACHINE LEARNING APPROACHES FOR THE DETECTION OF SUICIDAL TENDENCIES

With the increasing prevalence of mental health issues, particularly suicidal behaviors, the need for early and accurate detection has become critical. This paper explores the current landscape of machine learning approaches used for the detection of suicidal tendencies. It examines a wide range of machine learning techniques applied to various data sources, including social media, clinical records, psychological assessments, self-reported forms like PHQ-9, audio speech recordings, and multimodal data integrating speech and visual information. This comprehensive review aims to reveal the types of existing research based on these varied datasets, highlighting the nuances of data collection, significant features identified, and the results obtained by different studies. Additionally, the review discusses the challenges and limitations associated with these approaches, providing researchers and practitioners with valuable insights into the potential and pitfalls of machine learning applications in diagnosing individuals at risk of suicide. The goal is to inform future research and improve early detection methods to ultimately reduce suicide rates.

Structural homophobia and suicidal ideation and behavior among sexual and gender minority adolescents.

Structural homophobia and suicidal ideation and behavior among sexual and gender minority adolescents.
