Measurement Scales of Suicidal Ideation and Attitudes: A Systematic Review Article

Suicidal behavior and associated factors among holy water users at Northwest, Ethiopia, 2023: an institution based cross-sectional study

Background

Suicide is a serious cause of mortality that affects families, communities, and the entire country. Because of a lack of national systematic reporting for cause-specific mortality, a high level of stigma, and religious non-acceptance, suicidal behavior is an under-reported and concealed cause of death in the majority of low- and middle-income countries.

Objective

The aim of this study was to assess the prevalence of suicidal behavior and associated factors among holy water users at the Andassa Saint George Monastery, 2023.

Methods

An institution-based cross-sectional study was conducted at the Andassa Saint George Monastery from 5 April to 5 May 2023. A systematic random sampling method was utilized to select 423 study participants and the Suicidal Behaviors Questionnaire-Revised was used to assess suicidal behavior. The data were gathered using the epicollect5 software with a face-to-face interview method then exported to SPSS-25 for analysis. A binary logistic regression model was used and all variables in a bivariate analysis with a p-value of less than 0.25 were entered into a multivariable logistic regression model, and statistical significance was declared at a p-value of less than 0.05.

Results

The prevalence of suicidal behavior among holy water users was 9.7% (95% CI: 7.1-12.4). Being female [2.632 (1.206-5.748)], living alone [2.52 (1.06-5.97)], and having depression [3.03 (1.32-6.99)], epilepsy [3.82 (1.28-11.40)], and diabetes mellitus [3.37 (1.229-9.25)] were significantly associated with suicidal behavior.

Conclusion

In this study, almost 1 in 10 had engaged in suicidal behavior in their lifetime. Several risk factors for suicidal behavior were identified, including being female, living alone, and having diabetes mellitus, epilepsy, and depression.

Suicidality and Non-Suicidal Self-Injury: A Narrative Review of Measurement, Risk, and Disparities among Minoritized and System-Involved Youth in the USA

Suicidality and non-suicidal self-injury (NSSI) among youth in the United States continue to be a growing and serious public health concern. With alarming rates of suicide trending in the wrong direction, researchers are committed to bending the curve of suicide and reducing rates by 2025. Understanding the antecedents and conditions, existing measures, and disparate prevalence rates across minoritized groups is imperative for developing effective strategies for meeting this goal. This study presents a narrative review of the operationalization, measurement, risk factors (e.g., firearms and social media), and disparities across race, ethnicity, age, gender identity, ability, sexual orientation, immigration statuses, and system involvement (e.g., foster care and juvenile justice) of suicidality and non-suicidal self-harm across youth in the United States. Implications for research, practice, and policy approaches that incorporate positive youth development, cultural, and youth participation in interventions are discussed.

Ethical dilemmas and legal ambiguity in China: a chain mediation model linking suicide rumination, legitimization, and acceptance among acutely-ill adults

Background

This study explores the complex intersection of euthanasia, legal ambiguities, cultural attitudes, and the psychology of suicide among seriously ill patients in China. It addresses the lack of clear legislation on euthanasia and doctor-assisted killing, the impact of cultural and philosophical beliefs, and the evolution of legal and ethical perspectives on suicide. Additionally, it examines the psychological aspects of suicide ideation in acutely-ill patients, focusing on factors like familial burden and loss of dignity.

Method

A survey was conducted with 356 Chinese adults, aged 23 to 64 years, using popular social media platforms in China. The study aimed to reflect a broad spectrum of the adult population in terms of age, education, and professional sectors. The research model involves suicide rumination as an independent variable, acutely-ill patients' suicide acceptance as a dependent variable, and three mediators: cognitive depression, ethical suicide acceptance, and suicide legitimization.

Results

The findings reveal a significant total effect of Suicide Rumination on Acutely-ill Patients' Suicide Acceptance, underlining a robust direct relationship that supports Hypothesis 1. The analysis indicates that Suicide Rumination is a significant predictor of Cognitive depression, explaining approximately 8.05% of its variance, thereby fully supporting Hypothesis 2a. However, the effect of Suicide Rumination on Ethical Suicide Acceptance did not emerge as significant, failing to support Hypothesis 2b, while its impact on Suicide Legitimization was also non-significant, not supporting Hypothesis 2c. Cognitive depression was found to have a substantial effect in the models for both Ethical Suicide Acceptance and Suicide Legitimization, supporting Hypotheses 3a and 3b. In the comprehensive model assessing Acutely-ill Patients' Suicide Acceptance, incorporating all mediators, a significant variance (R-squared = 0.6625) was explained. Notably, Suicide Rumination, Ethical Suicide Acceptance, and Suicide Legitimization all emerged as significant predictors of this acceptance, with varying effects, thus supporting Hypotheses 4a and 4b. The role of Cognitive depression in this model was marginally significant, offering limited support for Hypothesis 4c. Crucially, the indirect effects of Suicide Rumination on Acutely-ill Patients' Suicide Acceptance through different mediational paths varied in significance and impact. The indirect effect via Cognitive depression alone, and through the sequential combination of Cognitive depression and Ethical Suicide Acceptance, were significant, highlighting the nuanced role of these mediators. These findings underscore the importance of considering multiple pathways in understanding the dynamics of Suicide Rumination and its influence on the acceptance of suicide among acutely-ill patients.

Conclusion

This paper presents a comprehensive analysis of the legal, cultural, ethical, and psychological dimensions of euthanasia, doctor-assisted killing, and suicide in China. The findings highlight the significant direct and mediated effects of suicide rumination on the acceptance of suicide among acutely-ill patients. The study contributes valuable insights into the evolving bioethics and the interplay of various factors in the context of end-of-life decision-making in modern Chinese society.

Suicide literacy mediates the path from religiosity to suicide stigma among Muslim community adults: Cross-sectional data from four Arab countries

BACKGROUND

The majority of research attention has been devoted to the link between religiosity and suicide risk, and a considerable amount of studies has been carried out on how stigma impacts individuals with mental health problems of different kinds. However, the interplay between religiosity, suicide literacy and suicide stigma has seldom been empirically researched, especially quantitatively. We sought through this study to redress the imbalance of research attention by examining the relationship between religiosity and suicide stigma; and the indirect and moderating effects of suicide literacy on this relationship.

METHOD

A cross-sectional web-based survey was conducted among Arab-Muslim adults originating from four Arab countries (Egypt: N = 1029, Kuwait: N = 2182, Lebanon N = 781, Tunisia N = 2343; Total sample: N = 6335). The outcome measures included the Arabic Religiosity Scale which taps into variation in the degree of religiosity, the Stigma of Suicide Scale-short form to the solicit degree of stigma related to suicide, and the Literacy of Suicide Scale explores knowledge and understanding of suicide.

RESULTS

Our Mediation analyses findings showed that literacy of suicide partially mediated the association between religiosity and stigmatizing attitude toward suicide. Higher religiosity was significantly associated with less literacy of suicide; higher literacy of suicide was significantly associated with less stigma of suicide. Finally, higher religiosity was directly and significantly associated with more stigmatization attitude toward suicide.

CONCLUSION

We contribute the literature by showing, for the first time, that suicide literacy plays a mediating role in the association between religiosity and suicide stigma in a sample of Arab-Muslim community adults. This preliminarily suggests that the effects of religiosity on suicide stigma can be modifiable through improving suicide literacy. This implies that interventions targeting highly religious individuals should pay dual attention to increasing suicide literacy and lowering suicide stigma.

Suicidal ideation, burnout, and their correlation among health care workers at the end of the fourth wave of the COVID-19 pandemic in Alborz Province, Iran

Background

During the COVID-19 pandemic, Health Care Workers (HCWs) were more vulnerable than ever to Burnout and Suicidal thoughts due to stressful work conditions. This study, investigated the level of Burnout and Suicidal thoughts among HCWs during the fourth wave of the pandemic in Alborz Province in Iran and compared it with the conditions at the beginning of the pandemic.

Methods

A total of 305 HCWs from 3 referral hospitals for COVID-19, including 155 men and 150 women, participated in the study. A cross-sectional study was carried out with a sample of HCWs dealing with COVID-19 patients using the available sampling method. The results of this online survey, which was conducted from June 7 to July 5, 2021 (at the end of the Fourth Wave of the COVID-19 Pandemic in Iran), have been compared with the conditions of the First Wave of the Pandemic (from February 24 to April 27, 2020). The participants were evaluated by the Beck Scale for Suicidal Ideations (BSSI) and Maslach Burnout Inventory (MBI).

Results

The mean age of the participants was 36.34 ± 7.37. The means of Suicide Index (SI), Emotional Exhaustion (EE), Depersonalization (DP), and Personal Accomplishment (PA) scores were 0.76 ± 1.74, 19.94 ± 4.69, 4.92 ± 1.51, and 31.30 ± 5.88, respectively. SI and PA were significantly higher in workers other than nurses and physicians and EE was higher among workers with night shifts (p value<0.05 in all indices). Age had a significant and negative correlation with EE (p value<0.01) and DP (p value<0.05) and a significant and positive correlation with PA (p value<0.01).

Conclusion

This study showed a high level of SI and Burnout indices among HCWs in the fourth wave of the pandemic in Iran. Paying attention to the factors affecting the development of social capital and creating health policy changes may be effective in reducing Burnout indices and high Suicide index among HCWs.

Depression, anxiety, psychological distress and associated factors among students attending Nemelifen Secondary and Preparatory School, Afar regional state, Ethiopia: a cross-sectional study

OBJECTIVES

This study aimed to assess the magnitude of depression, anxiety, psychological distress and associated factors in Nemelifen Secondary and Preparatory School at Awash 7 Kilo, zone 3, Afar, Ethiopia.

DESIGN

An institutional-based cross-sectional study design was implemented.

SETTING

This research was conducted in Afar regional state, zone 3, Awash 7 Kilo town.

PARTICIPANTS

A pretested, structured, self-administered questionnaire was used to gather information from 392 study participants. For the purpose of identifying risk variables for depression, anxiety and psychological distress, bivariate and multivariate binary logistic regression analyses were used.

OUTCOME MEASURES

The primary outcome of the study was magnitude of depression, anxiety and psychological distress and the secondary outcome was factors associated with depression, anxiety and psychological distress.

RESULTS

Overall, 109 study participants showed symptoms of depression (28.91%; 95% CI: 24.3%, 33.2%), 85 had symptoms of anxiety disorder (22.55%; 95% CI: 18.7%, 27.3%) and 168 had symptoms of psychological distress (44.56%; 95% CI: 39.6%, 49.6%). While anxiety was linked to ever drinking alcohol (adjusted OR (AOR)=2.87; 95% CI: 1.13, 7.28) and suicidal ideation (AOR=3.23; 95% CI: 1.80, 5.79), depression was significantly associated with having very good relationships with classmates (AOR=0.22; 95% CI: 0.09, 0.55) and suicidal ideation (AOR=2.26; 95% CI: 1.29, 3.94). The level of education (being in the ninth grade) and suicidal ideation (AOR=2.86; 95% CI: 1.49, 4.86) were also related to psychological distress.

CONCLUSION

High levels of depression, anxiety and psychological distress were discovered. Very positive relationships with classmates were significantly linked to depression, while ever drinking was linked to anxiety. Likewise, the level of educational was related to psychological distress. All three of the dependent variables were linked to suicidal ideation. Above all, there was a connection among psychological distress, anxiety and depression.

Psychometric evaluation of the 9-item Concise Health Risk Tracking - Self-Report (CHRT-SR9) (a measure of suicidal risk) in adolescent psychiatric outpatients in the Texas Youth Depression and Suicide Research Network (TX-YDSRN)

BACKGROUND

This study evaluated the psychometric properties of the 9-item Concise Health Risk Tracking Self-Report (CHRT-SR₉), a measure of suicidality, in adolescent psychiatric outpatients.

METHODS

Altogether, 933 depressed or suicidal adolescents (12-20 years of age), receiving treatment at psychiatric outpatient clinics in Texas, completed the 16-item CHRT-SR at baseline and one month later. CHRT-SR₉ was extracted from CHRT-SR₁₆ using multigroup confirmatory factor analysis. Sex and age measurement invariance, classical test theory, item response theory (IRT), and concurrent validity analyses (against the suicidal ideation Item 9 of Patient Health Questionnaire-Adolescent (PHQ-A)) were conducted.

RESULTS

The CHRT-SR₉ demonstrated excellent model fit with four factors (pessimism, helplessness, despair, and suicidal thoughts). Measurement invariance was upheld. Acceptable item-total correlations (0.56-0.80) and internal consistency (Spearman-Brown 0.78-0.89) were revealed. IRT analyses showed a unidimensional instrument with excellent item performance. Using the CHRT-SR₉ total score as a measure of overall suicidality and comparing it against levels of PHQ-A Item 9, the mean (standard deviation) of CHRT-SR₉ total score was 8.64 (SD = 5.97) for no-risk (0 on Item 9), 17.05 (SD = 5.00) for mild, 23.16 (SD = 5.05) for moderate, and 26.96 (SD = 5.24) for severe-risk (3 on Item 9). Significant differences (p-value<0.0001) indicated that CHRT-SR₉ total score distinguished between levels of suicidal risk. Furthermore, CHRT-SR₉ was sensitive to change over a one-month period.

LIMITATIONS

Whether CHRT-SR₉ predicts actual suicidal attempts in adolescents is not well defined.

CONCLUSION

The CHRT-SR₉ is an easy-to-administer, user-friendly self-report with good psychometric qualities which makes it an excellent screening measure of suicidal risk in adolescent psychiatric outpatients.

Long-Term Suicidal Ideation Profiles in Late-Life Depression and Their Association With Suicide Attempt or Death by Suicide

Objective: In young and middle-aged adults, suicidal ideation is an important predictor of prospective suicide attempts, but its predictive power in late life remains unclear. In this study, we used Latent Profile Analysis (LPA) in a cohort of depressed older adults to identify distinct ideation profiles and their clinical correlates and test their association with risk of suicidal behavior longitudinally.

Methods: A total of 337 depressed older adults (aged 50-93 years) were assessed for suicidal ideation and behavior for up to 14 years (median = 3 years), at least once per year (study period: 2002-2020). LPA was used, which derived 4 profiles of ideation scores based on subject-level aggregates. Groups were compared using analysis of variance (ANOVA) and χ2 tests at baseline and competing risk survival analysis during follow-up.

Results: Ideation showed significant decline over time, on average (P < .001). LPA identified 4 suicidal ideation profiles. Risk of suicide attempt/death was higher for chronic severe ideators (age-adjusted hazard ratio [HR] = 5.75; 95% CI, 2.25-14.7; P < .001) and highly variable ideators (HR = 3.21; 95% CI, 1.03-10.1; P = .045) compared to fast-remitting ideators, despite comparable current ideation severity at baseline. Fast-remitting ideators had higher risk than low/non-ideators with no attempts or suicides (P < .001). Chronic severe ideators displayed the most severe dysfunction across personality, social characteristics, and impulsivity measures, whereas highly variable and fast-remitting ideators displayed specific deficits.

Conclusions: Assessing suicidal ideation over months/years has clinical relevance, as it enabled the identification of distinct ideation patterns associated with substantive differences in clinical presentation and risk of future suicidal behavior despite similar ideation levels at baseline.

Suicide stigma measures: A scoping review

BACKGROUND

Worldwide, approximately 800,000 people die by suicide every year, and non-fatal suicidal thoughts and behaviours are common. Stigma is likely a major barrier to preventing suicide. The purpose of our review is to scope the development, psychometric properties and use of measures that explicitly seek to measure the construct of suicide stigma.

METHODS

We conducted a scoping review. We searched PubMed, PsycINFO, Embase and CINAHL using search terms related to suicide, stigma and measures/scales with no date limits. We included any measure the authors defined as measuring suicide-related stigma. Only peer-reviewed articles published in English were included.

RESULTS

We included 106 papers discussing 23 measures of suicide stigma; 82 provided data on psychometric properties. Measures assessed personal or public stigma; and stigma toward a range of suicidal phenomena (e.g., suicidal thoughts, those bereaved by suicide). 'Stigma' definitions varied and were not always provided. The Grief Experience Questionnaire, Suicide Opinion Questionnaire and Stigma of Suicide Scale were the most commonly cited. Measures varied in the strength of their psychometric properties.

LIMITATIONS

We only included papers in English. Because we included any measures authors defined as measuring suicide stigma, we may have included measures not commonly considered as measures of suicide stigma, and conversely we might have excluded relevant measures because they did not use the term 'stigma'.

DISCUSSION

This review aimed to assist in better understanding available suicide stigma measures, their strengths and weaknesses and current uses, and will inform the development of future suicide stigma measures.

The 9-item Concise Health Risk Tracking - Self-Report (CHRT-SR9) measure of suicidal risk: Performance in adult primary care patients

PURPOSE

To evaluate the psychometric properties of a 9-item Concise Health Risk Tracking Self-Report (or CHRT-SR₉) to assess suicidal risk in adult primary care outpatients.

METHODS

Overall, 369 adults completed the original 14-item version of CHRT-SR at baseline and within 4 months thereafter, from which the CHRT-SR₉ was extracted using multigroup confirmatory factor analysis. Measurement invariance (across age and sex) and classical test theory characteristics of the CHRT-SR₉ were evaluated. Concurrent validity was assessed by comparing CHRT-SR₉ responses to those of the suicide item in the Patient Health Questionnaire (PHQ-9), both cross-sectionally and as a change measure over time.

RESULTS

Confirmatory factor analysis identified the CHRT-SR₉ as the optimal solution. Factors included pessimism, helplessness, despair (2 items each) and suicidal thoughts (3 items). Measurement invariance held across sex and age groups, indicating that mean differences among sub-groups were real and not attributable to measurement bias. Classical test theory revealed acceptable item-total correlations overall (0.57-0.79) and internal consistency (Spearman-Brown from 0.76 to 0.90). Concurrent validity analyses revealed that the CHRT-SR₉ can measure both improvement and worsening of suicidality over time. A PHQ-9 response of 0, 1, 2, and 3 on the suicide item corresponded to 7.82 (5.53), 16.80 (4.99), 20.71 (5.36), and 25.95 (7.30) (mean and SD) on CHRT-SR₉ total score, respectively.

CONCLUSION

The CHRT-SR₉ is a brief self-report evaluating suicidality with excellent psychometric properties that is sensitive to change over time.

Assessing Suicidal Ideation in Young People With Depression: Factor Structure of the Suicidal Ideation Questionnaire

Evaluating suicidal ideation in young people seeking mental health treatment is an important component of clinical assessment and treatment planning. To reduce the burden of youth suicide, we need to improve our understanding of suicidal ideation, its underlying constructs, and how ideation translates into suicidal behaviour. Using exploratory factor analysis, we investigated the dimensionality of the Suicidal Ideation Questionnaire (SIQ) among 273 participants aged 15-25 with Major Depressive Disorder. Area under the receiver operating characteristic curve (AUROC) analysis was used to explore associations between latent factors and actual suicidal behaviour. Findings suggested that the SIQ assesses multiple factors underlying suicidal ideation. AUROC analyses demonstrated that latent factors relating to both active and passive suicidal ideation predicted past-month suicidal behaviour and suicide attempt. These findings contribute to an improved understanding of the complexities of suicidal ideation and relationships with suicidal behaviour in young people with depression.

Attitudes toward Suicide and the Impact of Client Suicide: A Structural Equation Modeling Approach

Previous research has revealed that mental health professionals (MHPs) often experience significant short- and long-term impacts in the aftermath of client suicide. Individual differences are significant, yet what factors explain these differences remain unclear. The current study aimed to investigate to what extent MHPs' attitudes toward (client) suicide could predict the short- and long-term impacts of client suicide. A total of 213 MHPs, aged between 18 and 75, reported on a client suicide and their attitudes toward (client) suicide using self-report questionnaires. The results indicate that MHPs who believe it is one's "rightful choice" to die by suicide report less and MHPs who believe "suicide can and should be prevented" report more impact of client suicide. Predictability and preventability of client suicide proved strongly, positively correlated; yet, neither predicted the impact of client suicide. Taken together, these findings highlight the importance of MHPs' attitudes toward (client) suicide with respect to clients and MHPs (self-)care.

Prevalence of suicidal ideation in pregnancy and the postpartum: A systematic review and meta-analysis

BACKGROUND

Suicidal ideation, a significant risk factor of suicide, is considered a potential trigger for intervention prior to self-harm or suicide; however, the prevalence of maternal suicidal ideation varied widely between studies. This review aims to synthesis the available evidence to estimate the prevalence of maternal suicidal ideation before and after pregnancy.

METHODS

We searched six English databases (PubMed, Web of Science, Embase, the Cochrane Library, PsycINFO, CINAHL) and three Chinese databases (China National Knowledge Infrastructure, Wang Fang, Chinese Biomedical Literature Databases) from database inceptions before August 31, 2020; and checked the reference list for relevant studies. Data in the included studies were used to calculate the prevalence of maternal suicidal ideation. Subgroup analysis and meta-regression were performed to detect the potential sources of heterogeneity.

RESULTS

6094 potentially studies were identified. 71 studies, including 23 cohort studies, 47 cross-sectional studies, and 1 RCT study, were included for final analysis. The total participants were 92146, with sample size ranged from 23 to 22118. The included studies were from 23 different countries distributing on six continents, most of the studies were conducted in Asia (n = 18), North America (n = 16), and South America (n = 15). The pooled prevalence of maternal suicidal ideation reported by eligible studies was 8% (95% CI 7-10%), with 10% in antenatal and 7% in postpartum. Prevalence significantly varied based on measuring tools, study design, study countries, and publication year, while prevalence was not conditional on the time-point assessment, sample size, and maternal age.

LIMITATION

Obvious heterogeneity and no standardization tools for measuring suicidal ideation may limit the results' interpretation.

CONCLUSION

Our systematic review reported the prevalence of suicidal ideation in pregnancy and postpartum was 8%. Future studies should establish standardization tools for measuring suicidal ideation and identify strategies of prevention and treatment.

Suicide in primary care: How to screen and intervene

Suicide is significant public health concern within the United States. Research results are mixed about the effectiveness of universal screening and interventions with patients who are at-risk for suicide. Primary care is a logical intervention point to mitigate risk among patients in each of these areas. The Department of Veterans Affairs and Department of Defense have developed comprehensive guidelines for the assessment and management of suicidal patients. This approach involves specific screening tools, risk stratification by categories and interventions used by clinicians to help reduce risk levels in their patients. This article aims to provide a model, built on the principles of these guidelines, which primary care physicians can use to identify, assess and intervene with patients who are at-risk for suicide.

Cerebrospinal fluid levels of monoamines among suicide attempters: A systematic review and random-effects meta-analysis

BACKGROUND

It remains unclear whether the dopaminergic and noradrenergic systems may be implied in suicide attempt risk. In addition, although the serotonergic system has been extensively studied, no formal meta-analysis has been performed to examine its association with suicide attempt.

METHODS

Using PRISMA methodology, we performed a systematic literature review and random-effects meta-analyses of the differences in cerebrospinal fluid (CSF) levels of 5-HIAA, HVA and MHPG between suicide attempters and individuals who never attempted suicide.

RESULTS

We identified 30 studies including 937 suicide attempters and 1128 non-attempters; 29 of them measured CSF levels of 5-HIAA, 22 measured CSF levels of HVA and 14 measured CSF levels of MHPG. CSF levels of 5-HIAA and HVA were significantly lower in suicide attempters than in non-attempters [SMD = -0.43 (95% CI: -0.71 to -0.15; p < 0.01) and SMD = -0.45 (95% CI: -0.72 to -0.19; p < 0.01), respectively]. We did not find a significant association between CSF MHPG levels and suicide attempt.

LIMITATIONS

Our analyses relied on a limited number of studies of good quality and most studies included small sample sizes.

CONCLUSION

Both serotonin and dopamine systems may play a role in suicide attempt risk. Our findings suggest that a silo approach to biomarkers should be phased out in favor of the study of multiple systems in parallel and in the same populations to progress in the identification of the biological components independently associated with suicide risk, with the goal of identifying new treatment targets and improving suicide risk prediction.

Prevalence and Associated Factors of Suicidal Behavior Among Patients and Residents in Northwest Ethiopia

There are a million suicide deaths in the world annually, and 75% of these occur in low- and middle-income countries (LMICs). However, there are limited resources to prevent suicidal deaths in those regions. The aim was to assess the prevalence of suicidal behavior and associated factors among patients visiting for medical care at a health center and residents in the community. A comparative study was employed by interviewing 2,625 residents in the community and 1,363 patients at the health center about suicidal behavior in northwest Ethiopia, from March 2017 to February 2018. Logistic analysis was employed with adjusted odds ratios and 95% confidence interval (CI) and with p-value < 0.05. The total prevalence of suicidal behavior (ideation, plan, and attempt) was found to be 5.6% (with 95% CI range 5-6%). It was found to be 4.4% with 95% CI range 4-5% in residents and 7.9% with 95% CI range 6-9% in patients. Female sex, depressive symptoms, physical/verbal abuse, and feeling stigmatized were identified as a risk factors for suicidal behavior, whereas a healthy lifestyle, such as eating regular meals of fruits and vegetables, doing physical exercise regularly, and having public health insurance were identified as protective risk factors for suicidal behavior even after adjusting for being a patient or not. The proportion of suicidal behavior was double in patients compared with residents. Suicidal behavior should be assessed in patients who visit for medical help and integration of mental health service within the primary health care system is recommended, especially in low-income countries.

A cross-cultural study of attitudes toward suicide among young people in India, Italy and Australia

BACKGROUND

An understanding of the cultural aspects of suicidal behavior is essential for the development of culturally appropriate suicide prevention and intervention strategies.

AIMS

This study explored the attitudes toward youth suicide in 686 Italian, Indian and Australian undergraduate students (18-24 years old).

METHOD

A 21-item suicide attitude inventory titled Attitude towards Youth Suicide (AtYS) scale, included in this paper, was used in the three samples.

RESULTS

Four factors were extracted, labeled negative attitudes toward suicide, belief that suicide was not preventable, suicide as acceptable and normal, and the existence of risk signs for suicide. Country differences were found for all four subscales, with Indian students having the most negative attitudes toward suicide. Sex differences were found in all three countries with women, on the whole, having less negative attitudes toward suicide, more belief in the preventability of suicide in India and more belief in risk signs for suicide in Italy.

CONCLUSION

Attitudes are linked to suicide in a complex manner. More quantitative and qualitative studies, including in lower-income and non-English speaking Western societies, are needed.

The effect of adverse childhood experiences on depression, psychological distress and suicidal thought in Vietnamese adolescents: Findings from multiple cross-sectional studies

Exposing to adverse childhood experiences (ACEs) has been identified as one of the major contributing factors to poor mental health and suicide in adolescents. However, little is known about this relationship in Vietnamese adolescents. This study aimed to evaluate the effect of ACEs on depression, psychological distress and suicidal thought among Vietnamese adolescents across different areas in Vietnam. Cross-sectional surveys were conducted among 4957 secondary school and high school students aged 13-20 in urban area, rural area, border area and mountainous area. The students were asked to complete a self-report questionnaire which included the Center for Epidemiological studies - Depression, the Kessler-10 and ACE questionnaire from the WHO Adverse Childhood Experiences Study. Suicidal thought was evaluated by a single question from the U.S. Youth Risk Behavior Survey. Among 4720 students included in the analysis, 54.4% were female. The prevalence of depression, psychological distress and suicidal thought was 22.9%, 30.6% and 10.9% respectively. About 86% of participants experienced at least one type of ACEs and nearly 56% reported multiple types of ACEs. Students with four or more types of ACEs had 6.98 (95% CI 5.09 -9.56), 4.72 (95 % CI 3.58-6.23) and 6.43 (95 % CI 4.45-9.30) times higher in odds of having depression, psychological distress and suicidal thought respectively. In conclusion, ACEs are common in Vietnamese adolescents and are strongly associated with depression, psychological distress and suicidal thought. Our finding indicates urgent needs for interventions targeting both ACEs and depression, psychological distress in Vietnamese adolescents.

Suicide: A Précis!

Background

Suicide remains a psychiatric emergency, tragedy, a public health burden, and for those aged 15-29, is the second leading cause of death globally. Stigma attached to psychiatric disorders and suicide means many people feel unable to seek help.

Aim of Work

We highlighted confusing nosology, psychopathology, neurobiological underpinnings, typology, and, risk factor pertinent to suicide. A road-map to the clinical assessment and management of suicide has also been provided. Last, but not least, we tried to dispel the long-held myths about suicide.

Methods

EMBASE, Ovid MEDLINE, PubMed, Scopus, Web of Science, and Cochrane Database of Systemic Reviews were searched for all relevant studies up to date of Jan, 2020.

Results

Suicide is self-inflicted death with evidence (explicit/implicit) of intention to die. Suicide reflects many disparate determinants release/relief, response-to the disordered thinking, religious, revenge, rebirth, reunification or rational. 5-HT deficiency appears central to the neurobiology of suicide. Durkheim proposed 4 types of suicide (egoistic, altruistic, anomic, fatalistic). Risk factors for suicide entail both static and dynamic factors. Dynamic factors encompass both clinical and situational variables. Shneidman's concepts of perturbation and psychache are very crucial to consider when assessing the risk. Suicide rating scales are only ancillary with the Modified high-risk construct scale balances vectors of suicidality versus survivality. Myths germane to suicide abound that need to be demystified. Psychiatric management capitalizes on determining a setting for treatment and supervision, attending to patient's safety, as well as working to establish a cooperative and collaborative physician-patient relationship. This entails both psychosocial 'package' and somatic treatments and the best outcomes mandate well-keeled combined approaches. Pharmacologic interventions aim chiefly at acute symptomatic relief. Recently, heaps of data accrue speaking to the idea of ground-breaking 'anti-suicidal' agents that might alleviate suicidal ideation (SI).

Conclusion

Suicide continues to be a complex public health problem of global calibre. It is variably tied to a myriad of risk factors underscoring likely etiological heterogeneity. That said, suicides can, at least partially, be prevented by restricting access to means of suicide, by training primary care physicians and health workers to identify people at risk as well as to assess and manage respective crises, provide adequate follow-up care and address the way this is portrayed in the media. A host of psychotherapeutic, pharmacological, or neuromodulatory treatments of mental disorders are readily available that can alter this acrimonious trajectory.

Suicidal behavior in problematic substance uses in South Gondar zone, Northwest Ethiopia: a cross-sectional survey

Background

Suicidal behavior has a significant contribution to the global burden of disease that affects individuals, families and communities at different age groups. Sadly, up to 75% of suicides in the world occur in low-and- middle income countries which have no adequate resource to prevent it. The aim of this study was to assess suicidal behavior and associated factors among community residents with problematic substance use in South Gondar zone, northwest Ethiopia.

Methods

Community based cross-sectional survey was conducted by using a suicidal behavior revised questionnaire from January 15 to March 15, 2019. A total of 4035 participants were screened for problematic substance use by using multi stage cluster sampling and 846 participants were positive for problematic substance use then asked for suicidal behavior. Multiple logistic regression analyses used to see adjusted odd rations (AOR). Multilevel binary logistic regression was used to account for the hierarchical structure of the two-level data within individual and districts level.

Results

The prevalence of suicidal behavior over the last 12 months in problematic substance uses was found to be 41.4% with 95% of confidence interval (CI) (38.2–44.9). Perceived stigma, [AOR = 1.605, 95% CI (1.16–2.23)], family history of suicide [AOR = 3.22, 95% CI (1.46–7.10)], physical illness [AOR = 2.45 95% CI (1.157–3.84)], rural resident [AOR = 1.74, 95% CI (1.16–2.62)], depression [AOR = 4.44, 95% CI (3.15–6.27)] and living alone (AOR = 1.61, 95% CI (1.16–2.24) were risks factors for suicidal behavior.

Conclusion

Suicidal behavior in problematic substance uses found to be high. Health workers should pay attention to decrease suicidal behavior and to control amendable factors.

Psychometric evaluation of the Interpersonal Needs Questionnaire (INQ) using item analysis according to the Rasch model

The Interpersonal Needs Questionnaire (INQ) assesses Thwarted Belongingness (TB) and Perceived Burdensomeness (PB), two predictors of suicidal thoughts. Up to now, the use of item response theory (IRT) for the evaluation of the INQ has been restricted to a single study with clinically depressed and suicidal youth. Therefore, the psychometric properties of the two INQ-15-subscales TB and PB were now evaluated in a general population sample (N = 2508) and a clinical adult population sample (N = 185) using IRT, specifically the Rasch model (RM) and the graphical log-linear Rasch model (GLLRM). Of special interest was whether the INQ-subscales displayed differential item functioning (DIF) across the two different samples and how well the subscales were targeted to the two sample populations. For the clinical sample, fit to a GLLRM could be established for the PB-subscale and fit to a RM was established for a five-item version of the TB-subscale. In contrast, for the general population sample fit to a GLLRM could only be achieved for the PB-subscale. Overall, there was strong evidence of local dependence (LD) across items and of some age- and gender-related DIF. Both subscales exhibited massive DIF related to the sample, indicating that they don’t work the same across the general population and clinical sample. As expected, targeting of both INQ-subscales was much better for the clinical population. Further investigations of the INQ-15 under the Rasch approach in a large clinical population are recommended to determine and optimize the scale performance.

Suicidal ideation from parents to their children: An association between parent's suicidal ideation and their children's suicidal ideation in South Korea

BACKGROUND

Suicide has been a major social and public health issue for Koreans, and currently, we are witnessing an increasing rate of teen suicides. This study's purpose was to investigate suicidal ideation in families by examining the associations between suicidal ideation between parents and their offspring using a representative sample of the Korean population.

METHODS

This cross-sectional study used data collected for the Korean National Health and Nutrition Examination Survey (KNHANES) from 2007 to 2013 and 2015. The study population consisted of 2324 adolescents 12 to 18 years-old and both parents. We used the chi-square test and logistic regression for the data analyses. The outcome variable was suicide ideation among adolescents adjusted for depressive symptoms, stress level, and the parental variables.

RESULTS

In total, 16.1% of the parents had suicidal ideation and 18.4% of the adolescents experienced suicidal ideation that was influenced by their parents. The adjusted odds ratio between the suicidal ideation of the parents and adolescents was 2.01 (95% CI 1.32-3.05). Depressive symptoms (AOR: 5.43, 95% CI 3.66-8.04) and stress level (AOR: 15.51 95% CI 6.14-39.19) were major risk factors for offspring's suicidal ideation. The association of the fathers' suicidal ideation with their offspring's suicidal ideation was greater than that of the mothers.

CONCLUSION

Knowing the risk factors of the offspring's suicidal ideation can prevent teen suicide and protect adolescents at risk. Thus, suicide prevention at the family level should be examined in relation to traditional risk factors at the individual level.

Relationship Between Debt and Depression, Anxiety, Stress, or Suicide Ideation in Asia: A Systematic Review

Background: This article aims to review research manuscripts in the past 5 years that focus on the effects of debt on depression, anxiety, stress, or suicide ideation in Asian countries. Methods: A search for literature based on the PRISMA guidelines was conducted on Medline, PubMed, Web of Science, Scopus, and ScienceDirect, resulting in nine manuscripts meeting inclusion criteria. The studies were conducted in Thailand, Korea, Singapore, Pakistan, India, Cambodia, and China. Results: The findings of the studies show that there is evidence to support that being in debt is related to Asian participants experiencing depression, anxiety, stress, or suicide ideation. However, the studies are limited to quantitative studies only. The definition of debt is also unclear in most manuscripts. Few manuscripts also examined how other factors influence the relationship between debt and mental illness. Conclusion: There are limited studies on the psychological effects of debt on the Asian population. Future studies should focus on the relationship between debt and psychological well-being among this population.

Psychometric Properties of the Suicide Acceptance Questionnaire

Only a few questionnaires are available for measuring attitude towards suicide as a unidimensional construct, i.e. emphasizing acceptance or disapproval of the suicidal act under a set of difficult life circumstances. The aim of this study was to develop the Suicide Acceptance Questionnaire (SAQ) and examine its psychometric properties. A group of 177 Psychology, Medicine and Law students completed the SAQ, Attitudes Towards Suicide questionnaire and a demographic survey. Exploratory factor analysis found the SAQ to have a single factor structure, explaining 55.49% of variance, with high goodness of fit. Owing to the nature of explicit attitudes, the SAQ may have limited power in predicting behavior. The findings indicate that the SAQ demonstrates appropriate reliability and concurrent validity for measuring the acceptance of suicide act. Future research with use of confirmatory factor analysis is needed for determining whether the proposed construct fits data.

Are stressful life events prospectively associated with increased suicidal ideation and behaviour? A systematic review and meta-analysis

BACKGROUND

Stressful life events are a risk factor for suicidal ideation and behaviour, but the strength and nature of this association is unclear. This review examined the prospective relationship between stressful life events and subsequent suicidal ideation and behaviours.

METHODS

Five databases were searched from inception to April 2019. Eligible studies included observational, quantitative longitudinal cohort studies with adult or adolescent samples. A random-effects meta-analysis model was used to examine the prospective relationship between stressful life events and subsequent suicidal ideation and behaviours. Sub-group analyses examined moderating factors.

RESULTS

Eight studies were identified in the systematic review, and seven studies comprising 2,639 participants were included in the meta-analysis. Six studies investigated suicidal ideation and one investigated suicidal behaviours. Stressful life events were associated with a 37% higher odds of subsequently reported suicidal ideation and behaviours combined (Odds Ratio (OR): 1.37, 95% CI: 1.10 to 1.70), and a 45% increased risk for suicidal ideation (OR: 1.45, 95% CI: 1.20 to 1.75). This association was stronger in males, young adults, and studies with shorter term follow-up.

LIMITATIONS

The analyses indicated statistical heterogeneity was high (I2 = 76. 48, 95% CI: 55.0 to 87.7%) and there was evidence of publication bias.

CONCLUSIONS

Stressful life events were shown to increase the risk of subsequently reported suicidal ideation and behaviours. These findings suggest that the experience of stressful life events should be incorporated into clinical suicide risk assessments and suicide interventions could include a component on developing resilience and adaptive coping to stressful life events.

"Can we talk?": A longitudinal analysis of Latino & non-Hispanic parent-child connectedness & adolescent ideation

BACKGROUND

Over 16 million U.S. adults report a major depressive episode each year. Hispanic females comprise the highest number of U.S. births compared to other race/ethnicities and are expected to remain as the Hispanic population grows. Research postulates that depression often co-occurs within families and is passed down to future generations but has yet to determine racial/ethnic disparities for depression and more acute forms including ideation.

METHODS

Using data from the Fragile Families and Child Wellbeing Study, latent class analyses examined the association of primary caregiver's (PCG) depressive symptoms and how their child's perceived level of parent-child closeness is related to their now-adolescent's (age 15) likelihood of ideation (N = 4,898 families).

RESULTS

Hispanic PCG's reported a lower rate of depressive symptoms (37%) than non-Hispanic PCG's (45%). Hispanic PCG's depressive symptoms were more likely to be chronic throughout their adolescent's lifetime (15%). Regardless of race/ethnicity, PCG's chronic depressive symptoms negatively affected parental closeness and increased suicidal risk for adolescents. These associations were found at ages 9 and 15 for non-Hispanic families, and at age 15 for Hispanic families.

LIMITATIONS

While this is an important first step, parental closeness and ideation can wax and wane. Asking teens about ideation before adolescence could have strengthened our study.

CONCLUSIONS

Suicide prevention must be family system focused, and not solely adolescent focused. Impressing upon individuals who serve children (i.e. teachers) and adults (i.e. physicians) to include yearly depression and suicide screens/assessments is crucial given PCG's different wave presentations and how ideation can present as early as middle school.

Validation and psychometric properties of Suicide Behaviors Questionnaire-Revised (SBQ-R) in Iran

BACKGROUND

Suicide is increasing in young Iranian population, which necessitates the employing of valid, yet abridged instruments assessing the constellation of suicide-related behaviors. The study aimed at validating Suicide Behavior Questionnaire-Revised (SBQ-R) among Iranian undergraduates.

METHODS

A total of 487 undergraduates were surveyed in 2018. Construct validity of SBQ-R was examined via confirmatory factor analysis (CFA), and Spearman's correlation with two single-item indices of suicide acceptability (SA) and lifetime suicidal ideation (LSI) was determined. Logistic regression and Kruskal-Wallis tests were used to examine the cut-off points (≥ 7 and ≥ 8) and categorizations as per item 1.

RESULTS

The mean SBQ-R score was 5.79 ± 3.55. Cut-off points ≥ 7 and ≥ 8 categorized 150 (30.8%) and 123 (25.2%) samples with suicide risk, respectively. Women obtained significantly higher scores on all indices, except items 1 and 4. CFA confirmed the model with sound goodness-of-fit, with factor loadings of 0.70 to 0.83. Composite reliability and average variance extracted were 0.87 and 0.63, respectively. The SBQ-R's correlation with SA and LSI confirmed its concurrent validity. Regression analysis confirmed the ability of both cut-off points to distinguish the participants with high SA and LSI; however, the cut-off point ≥ 8 produced better results regarding high LSI. Based on item 1, normal versus low- and high-risk samples were significantly different in terms of SA, LSI, and adjusted total score of SBQ-R (P < 0.0001).

CONCLUSION

SBQ-R is an economic and psychometrically sound tool, which can be utilized to identify suicide-related behaviors and risks in young Iranian population.

Helping or Heightening Vulnerability? Midwives as Arbiters of Risk for Women Experiencing Self-Directed Violence in Urban Sri Lanka

The response of midwives to women engaging in self-directed violence (SDV) may affect women's care and outcomes. The author explored midwives' understanding of SDV through semi-structured focus groups and in-depth interviews with 11 Public Health Midwives in urban Sri Lanka. Thematic analysis identified four key themes: (a) perceived dimensions of women's risk and vulnerability to SDV, (b) midwives as arbiters of risk, (c) representations of women engaging in SDV, and (d) midwives' perceived capacity to respond. Given their proximity to communities, trustworthiness as sites of disclosure, and respectability as women and guardians of ideal womanhood in Sri Lankan society, midwives occupy a powerful position in the health system through which to alleviate or reinforce women's risk to SDV. Yet, investment in developing their skills and role to respond to the growing phenomenon of SDV among women in Sri Lanka must consider the context within which midwives assess and select their responses.

Linguistic adaptation and psychometric properties of the Columbia-Suicide Severity Rating Scale among a heterogeneous sample of adolescents in Turkey

OBJECTIVE

The Columbia-Suicide Severity Rating Scale is a semistructured, interview-based assessment tool, which is increasingly being used for clinical and research purposes across the globe, despite its limited psychometric evaluation outside of English-speaking populations. The aim of this study was to linguistically adapt the measure and investigate reliability, validity, and factor structure of the Turkish version of the Columbia-Suicide Severity Rating Scale in a heterogeneous sample of psychiatric and nonpsychiatric outpatient adolescents.

METHOD

The study included four clinical groups: two psychiatric, nonsuicidal outpatient groups (depression group (N = 50) and nondepression group (N = 50)), suicidal group (N = 43), and nonpsychiatric general practitioners' group (N = 70). All participants were interviewed with the Columbia-Suicide Severity Rating Scale and suicidality module of the Mini International Neuropsychiatric Interview for children and adolescents. They also completed the Suicide Probability Scale, Child Depression Inventory, Beck Hopelessness Scale, and their parents filled in the Child Behavior Checklist.

RESULTS

The scale was found to be a solidly reliable measure with good internal consistency and agreement among interviewers. It correlated in the expected direction with self- and parent-report measures of associated constructs (e.g., depression) as well as suicidality. Consistent with the developers' intent of theoretical subscales, a three-factor solution (i.e., the severity of suicidal ideation, the intensity of suicidal ideation, and suicidal behavior) fit the data well, and it fit the data significantly better than the alternative models. Last, the Turkish Columbia-Suicide Severity Rating Scale successfully discriminated the adolescents with a recent history of suicide attempts from other clinical groups.

CONCLUSION

The Turkish version of the Columbia-Suicide Severity Rating Scale is a reliable and valid instrument to assess suicide risk among adolescents.

The dimensionality of suicidal ideation and its clinical implications

OBJECTIVES

No consensus has been reached regarding the theoretical dimensions underlying the Scale for Suicide Ideation (SSI) and Beck's Scale for Suicide Ideation (BSI), widely used in research and clinical practice. This undermines the understanding and management of suicidal behavior.

METHODS

The factor structure of the SSI and the BSI was investigated in 201 patients visiting the emergency department of the Geneva University Hospital, Switzerland, for suicidal ideation or a suicide attempt.

RESULTS

Exploratory factor analyses (EFAs) identified a unique theoretical dimension. Item removal based on analyses of communalities improved the explained part of variance in both scales. A joint factor analysis provided results very similar to those yielded by initial EFAs.

CONCLUSIONS

The single factor underlying the SSI and the BSI was composed of items encompassing a construct of suicide desire. Nonretained items corresponded to other elements of suicidal behavior (e.g., plans and preparations regarding the upcoming suicide attempt). These scales could not discriminate between suicide ideators and suicide attempters.

Psychometric evaluation of the Questionnaire on Attitudes Towards Suicide (ATTS) in Poland

The Questionnaire on Attitudes Towards Suicide (ATTS) is widely used to evaluate the views of an individual regarding acceptability of suicide and orientation towards suicide prevention. However, recent findings suggest that it requires some revision. The present study examines the factor structure of the ATTS questionnaire in two Polish samples, consisting of 239 students (sample one) and 128 students (sample two) of the helping professions. The previously-established 10-factor model was not supported by confirmatory factor analysis (CFA). Theoretical revaluation of the scale followed by factor analysis suggested that the best fit was provided by a five-factor model accounting for 48.2% of the variance. The adapted Polish ATTS questionnaire showed satisfactory reliability and validity; however, the factor loading patterns and factor structure varied from earlier studies. These improvements in the ATTS theoretical base and construct validity may enhance the utility of the revised scale.

Suicide, Stigma, and Utilizing Social Media Platforms to Gauge Public Perceptions

Introduction: Suicide, a multifaceted complex outcome that arises from numerous biopsychosocial factors, is a public health concern which is growing in numbers despite valiant prevention efforts. There is still a lot of stigma surrounding suicide that needs to be addressed. Social media is growing exponentially and there are many forums where suicidality is being discussed. As a result, we conducted a brief survey on the perception of suicide on social media platforms of Facebook and Reddit in order to gather more information. Results: Of the 152 respondents, 86% believed that suicide is preventable, and 72.85% believed that it is a person's right to die by suicide. About a third (31.79%) had lost someone close to them to suicide. Respondents who did not think suicide was preventable also viewed suicide as either a sign of strength (42.86%) or a revenge act (33.3%). Those who responded that someone close to them died by suicide believed that the media glorified suicide (56.25%) while those who did not lose someone, did not believe that (66.99%). Women (61%) found social media to be a good platform for people to ask for help while men did not (60.61%). Conclusions: We utilized the social media platforms to gauge the perception of suicide and found among the sample of mostly young white respondents, suicide is not stigmatized, most believed it is preventable and it is a person's right to die by suicide. While women found social media to be a good platform to ask for support, men did not, which is in keeping with the trend that women tend to be more willing to seek help. A third of the group had lost someone close to them to suicide which was the national average, who tended to believe that media glorified suicide. Limitations of this study include the fact that those who respond voluntarily to a survey likely have an interest in the topic, and this might not accurately reflect the public opinion and attitude.

Is a brief self-report version of the Columbia severity scale useful for screening suicidal ideation in Chilean adolescents?

BACKGROUND

Given the high rates of suicide in the adolescent population and the reluctance of this population to seek help, developing proactive and effective strategies to timely detect individuals at high risk for suicide in non-clinical contexts is a worldwide recognized need. A series of brief self-report questionnaires have been developed for this purpose, however there are few studies providing evidence on their capability to accurately classify suicidal risk levels in specific populations. One of the instruments frequently used to evaluate suicide risk is the Columbia-Suicide Severity Rating Scales (C-SSRS). The goal of this study is to provide psychometric evidence about the accuracy of the Suicidal Ideation subscale (SI) of the C-SSRS to classify suicidal risk levels in a sample of Chilean adolescents using Item Response Theory (IRT).

METHODS AND MATERIALS

Through the two parameter logistic model (2-PLM), we analyzed the capability of a self-report questionnaire addressing suicidal ideation (SI) to differentiate and classify participants according to their SI severity levels. We tested two main parameters: difficulty (localization) and discriminating power of 6 items extracted and adapted from the Columbia-Suicide Severity Rating Scales (C-SSRS). We administered this questionnaire to a general sample of 1645 adolescents aged 13 to 18.

RESULTS

Our results show that the items differentiate symptoms addressing suicidal thoughts according to their severity, providing an accurate classification of the SI risk level.

CONCLUSIONS

These findings support the usage of the C-SSRS in Chilean adolescents. Further research is needed to test its predictive value in different populations.

Use of a Machine Learning Algorithm to Predict Individuals with Suicide Ideation in the General Population

OBJECTIVE

In this study, we aimed to develop a model predicting individuals with suicide ideation within a general population using a machine learning algorithm.

METHODS

Among 35,116 individuals aged over 19 years from the Korea National Health & Nutrition Examination Survey, we selected 11,628 individuals via random down-sampling. This included 5,814 suicide ideators and the same number of non-suicide ideators. We randomly assigned the subjects to a training set (n=10,466) and a test set (n=1,162). In the training set, a random forest model was trained with 15 features selected with recursive feature elimination via 10-fold cross validation. Subsequently, the fitted model was used to predict suicide ideators in the test set and among the total of 35,116 subjects. All analyses were conducted in R.

RESULTS

The prediction model achieved a good performance [area under receiver operating characteristic curve (AUC)=0.85] in the test set and predicted suicide ideators among the total samples with an accuracy of 0.821, sensitivity of 0.836, and specificity of 0.807.

CONCLUSION

This study shows the possibility that a machine learning approach can enable screening for suicide risk in the general population. Further work is warranted to increase the accuracy of prediction.

Psychometric properties of the concise health risk tracking (CHRT) in adolescents with suicidality

BACKGROUND

Several self-report rating scales have been developed to assess suicidal ideation, yet few examine other factors related to increased suicidal risk, and even fewer have been validated in both adolescents and adults. We evaluate the 14-item Concise Health Risk Tracking - Self Report (CHRT-SR), a measure previously validated in adults, in a sample of adolescents at risk for suicide.

METHOD

Data are from a retrospective chart review of adolescents treated in an intensive outpatient program for youth with severe suicidality. Teens completed the CHRT-SR and Quick Inventory of Depressive Symptomatology - Adolescents (QIDS-A) at baseline and discharge. The CHRT-SR was evaluated to determine the factor validity, internal consistency, construct validity, and sensitivity to change.

RESULTS

Adolescents (n = 271) completed the CHRT-SR prior to treatment, and 231 completed the CHRT-SR at discharge. Three factors were identified with excellent model fit: Propensity, Impulsivity, and Suicidal Thoughts. Internal consistency reliability coefficients were good-to-excellent for the total score and all three factors at baseline (a = 0.774-0.915) and exit (a = 0.849-0.941). The total score and all three factors significantly correlated with overall depression severity and suicidal ideation as rated by teens and parent (p = .704-0.756, all p < .001). The CHRT-SR was sensitive to change, with moderate to large effect sizes (Cohen's d = 0.599-1.062).

LIMITATIONS

Study limitations include generalizability, lack of a control group, and retrospective data from a sample of opportunity.

CONCLUSIONS

The CHRT-SR is a reliable and valid measure for examining severity of suicidal thoughts and associated risk factors, and is sensitive to change following an intervention in adolescents.
