Suicidal ideation of psychiatrically hospitalized adolescents has one-year predictive validity for suicide attempts in girls only

Systematic Review: The Measurement Properties of the Suicidal Ideation Questionnaire and Suicidal Ideation Questionnaire-Jr

OBJECTIVE

The Suicidal Ideation Questionnaire (SIQ) and the Suicidal Ideation Questionnaire-Junior (SIQ-Jr) were designed to capture suicidal ideation in adolescents and are often used in clinical trials. Our aim was to identify and appraise the published literature with respect to the validity, reliability, responsiveness, and interpretability of the SIQ and SIQ-Jr.

METHOD

We conducted a systematic review following COnsensus-based Standards for the selection of health Measurement Instruments (COSMIN) guidelines to identify, appraise, and synthesize published literature on measurement properties and interpretability of the SIQ and SIQ-Jr. We searched MEDLINE, Embase, APA PsycINFO, CINAHL, Web of Science, and Scopus from inception to May 16, 2023, to identify sources relevant to our aim.

RESULTS

We identified 15 sources meeting our eligibility criteria. The body of literature did not meet COSMIN standards to make recommendations for use with regard to these measurement instruments.

CONCLUSION

Further research is needed, with a focus on content validity and structural validity, prior to recommending the SIQ and SIQ-Jr for use in clinical practice and in clinical trials. No specific grant funding was used for this review.

PLAIN LANGUAGE SUMMARY

In this systematic review, authors analyzed 15 sources examining measurement properties of the Suicidal Ideation Questionnaire and Suicidal Ideation Questionnaire-Jr. Both measures are designed to capture suicidal ideation in adolescents and are used in clinical practice and clinical trials. The authors identified sufficient evidence for convergent validity for both measures. Authors concluded that further research is needed to support content validity, structural validity as a unidimensional scale (as they are often used) as well as their internal consistency, test-retest reliability, discriminative validity, predictive validity, and interpretability of these measures. The authors also emphasize the need to consider the limitations of these measures for researchers studying suicidal ideation and clinicians using these measures in their assessments of young people.

Connected for life: How social connectedness can help prevent suicide in American Indian and Alaska Native communities

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

Psychometric validation of the Montgomery-åsberg Depression Rating Scale - Youth (MADRS-Y) in a clinical sample

BACKGROUND

Depression in adolescence is a serious major global health problem with increasing rates of prevalence. Measures of depression that are valid for young people are clearly needed in clinical contexts.

METHODS

The study included 577 patients from child and adolescent psychiatry (n = 471) and primary care (n = 106) aged 12-22 years in Sweden (Mage=16.7 years; 76% female). The reliability and validity for Montgomery-Åsberg Depression Rating Scale - Youth (MADRS-Y) were investigated. To confirm the latent structure, we used a single-factor confirmatory factor analysis (CFA). A Kruskal-Wallis test was performed to test total score differences between diagnostic groups. Using Spearman's rho correlations, we examine whether single items in the MADRS-Y correlate with suicidal ideation measured by The Suicidal Ideation Questionnaire-JR (SIQ-JR).

RESULTS

The internal consistency using McDonald's coefficient omega was excellent. The CFA of the 12-item MADRS-Y supported a one factor structure. Evidence of convergent and discriminant validity was shown. There was a significant difference in MADRS-Y scores across diagnostic groups, with higher results for depressive disorders. A strong correlation with suicidal ideation was found for two items.

CONCLUSIONS

The results support MADRS-Y as a brief, reliable, and valid self-report questionnaire of depressive symptoms for young patients in a clinical setting.

Prediction of suicidal ideation among preadolescent children with machine learning models: A longitudinal study

BACKGROUND

Machine learning (ML) has been widely used to predict suicidal ideation (SI) in adolescents and adults. Nevertheless, studies of accurate and efficient models of SI prediction with preadolescent children are still needed because SI is surprisingly prevalent during the transition into adolescence. This study aimed to explore the potential of ML models to predict SI among preadolescent children.

METHODS

A total of 4691 Chinese children (54.89 % boys, Mage = 10.92 at baseline) and their parents completed relevant measures at baseline and the children provided 6-month follow-up data for SI. The current study compared four ML models: Random Forest (RF), Decision Tree (DT), Support Vector Machine (SVM), and Multilayer Perceptron (MLP), to predict SI and to identify variables with predictive value based on the best-performing model among Chinese preadolescent children.

RESULTS

The RF model achieved the highest discriminant performance with an AUC of 0.92, accuracy of 0.93 (balanced accuracy = 0.88). The factors of internalizing problems, externalizing problems, neuroticism, childhood maltreatment, and subjective well-being in school demonstrated the highest values in predicting SI.

CONCLUSION

The findings of this study suggested that ML models based on the observation and assessment of children's general characteristics and experiences in everyday life can serve as convenient screening and evaluation tools for suicide risk assessment among Chinese preadolescent children. The findings also provide insights for early intervention.

Predicting Lifetime Suicide Attempts in a Community Sample of Adolescents Using Machine Learning Algorithms

Suicide is a major global health concern and a prominent cause of death in adolescents. Previous research on suicide prediction has mainly focused on clinical or adult samples. To prevent suicides at an early stage, however, it is important to screen for risk factors in a community sample of adolescents. We compared the accuracy of logistic regressions, elastic net regressions, and gradient boosting machines in predicting suicide attempts by 17-year-olds in the Millennium Cohort Study (N = 7,347), combining a large set of self- and other-reported variables from different categories. Both machine learning algorithms outperformed logistic regressions and achieved similar balanced accuracies (.76 when using data 3 years before the self-reported lifetime suicide attempts and .85 when using data from the same measurement wave). We identified essential variables that should be considered when screening for suicidal behavior. Finally, we discuss the usefulness of complex machine learning models in suicide prediction.

Factors within the clinical encounter that impact upon risk assessment within child and adolescent mental health services: a rapid realist synthesis

Background

Risk assessment is a key process when a child or adolescent presents at risk for self-harm or suicide in a mental health crisis or emergency. Risk assessment by a healthcare professional should be included within a biopsychosocial assessment. However, the predictive value of risk-screening tools for self-harm and suicide in children and adolescents is consistently challenged. A review is needed to explore how best to undertake risk assessment and the appropriate role for tools/checklists within the assessment pathway.

Aims

To map research relating to risk assessment for child and adolescent mental health and to identify features that relate to a successful risk assessment.

Objectives

To review factors within the clinical encounter that impact upon risk assessments for self-harm and suicide in children and adolescents: i. to conduct a realist synthesis to understand mechanisms for risk assessment, why they occur and how they vary by context ii. to conduct a mapping review of primary studies/reviews to describe available tools of applicability to the UK.

Data sources

Databases, including MEDLINE, PsycINFO®, EMBASE, CINAHL, HMIC, Science and Social Sciences Citation Index and the Cochrane Library, were searched (September 2021). Searches were also conducted for reports from websites.

Review methods

A resource-constrained realist synthesis was conducted exploring factors that impact upon risk assessments for self-harm and suicide. This was accompanied by a mapping review of primary studies/reviews describing risk-assessment tools and approaches used in UK child and adolescent mental health. Following piloting, four reviewers screened retrieved records. Items were coded for the mapping and/or for inclusion in the realist synthesis. The review team examined the validity and limitations of risk-screening tools. In addition, the team identified structured approaches to risk assessment. Reporting of the realist synthesis followed RAMESES guidelines.

Results

From 4084 unique citations, 249 papers were reviewed and 41 studies (49 tools) were included in the mapping review. Eight reviews were identified following full-text screening. Fifty-seven papers were identified for the realist review. Findings highlight 14 explanations (programme theories) for a successful risk assessment for self-harm and suicide. Forty-nine individual assessment tools/approaches were identified. Few tools were developed in the UK, specifically for children and adolescents. These lacked formal independent evaluation. No risk-screening tool is suitable for risk prediction; optimal approaches incorporate a relationship of trust, involvement of the family, where appropriate, and a patient-centred holistic approach. The objective of risk assessment should be elicitation of information to direct a risk formulation and care plan.

Limitations

Many identified tools are well-established but lack scientific validity, particularly predictive validity, or clinical utility. Programme theories were generated rapidly from a survey of risk assessment.

Conclusions

No single checklist/approach meets the needs of risk assessment for self-harm and suicide. A whole-system approach is required, informed by structured clinical judgement. Useful components include a holistic assessment within a climate of trust, facilitated by family involvement.

Measurement Choices for Youth Suicidality

Suicide is among the leading causes of death among individuals ages 10-24, making suicidal thoughts and behaviors (STBs) a serious public health crisis among youth. Suicide risk screening and assessment are vital to addressing this public health crisis. In fact, many youths that screen positive for suicidal ideation do not have known mental health concerns and would have been missed if not asked directly. Medical settings are an optimal setting to detect suicidality early and provide appropriate follow-up monitoring and care as needed. To support effective and efficient screening and assessment of suicidal thoughts and behaviors, providers must choose measures with both strong psychometric properties and clinical utility. While measurement of STBs can vary across health settings, suicide risk screening and assessment typically involves gathering information about current suicidal ideation, suicidal behaviors, and suicidal plans via self-report questionnaires, clinical interviews, and/or computerized adaptive screens. In alignment with measurement-based care efforts, the current manuscript will provide a scoping review of measures of youth suicidal ideation, behavior, plans, and their risk factors. Specifically, the psychometric properties, clinical utility, and other key considerations for screening and assessment of adolescent suicide risk are discussed.

Suicides among Children and Adolescents in Paraguay: An 18-year National Exploratory Study (2004-2022)

BACKGROUND

Suicide and suicide attempts are impacting events for patients and their relatives, and these behaviors are still taboo among adults and may be even more traumatic when involving children and adolescents.

AIM

In this study we aimed to describe suicide rates among children and adolescents in Paraguay over the last decades as well as associated factors such as sociodemographic characteristics and methods used for suicide.

METHODS

This was an observational and exploratory study describing the frequency and characteristics of suicide among children and adolescents in Paraguay between 2004 and 2022. Official records of all deaths by suicide were reviewed, and statistical analyses were performed. In addition, an attempt was made to predict the number of suicides in the next 5 years using a mathematical model based on simple linear regression.

RESULTS

In the 18-year period observed, 940 suicides among children and adolescents were recorded. The mean age was 15.05 ± 1.8 years old. Of these, 51.17% were male, 74.6% were from urban areas, and 22.2% were from the Greater Asunción and Central Department of Paraguay. The most frequently used method of suicide was intentional self-inflicted injury by hanging, strangulation, or suffocation, which all represented 75.3% of the cases. Our mathematical modeling based on simple linear regression determined that the expected yearly number of national suicides in the pediatric population for the following years, from 2023 to 2027, will range between 72 and 81.

CONCLUSION

This study is the first large national epidemiological report on the emerging issue of suicide among children and adolescents in Paraguay. It may be a relevant source of information for mental health professionals, health authorities, and decision makers to develop national prevention strategies and actions against suicide among youths.

Comparative analysis of the effect of interactive audio-visual based art therapy and music therapy in reducing suicidal ideation among school children who survived abduction

This study looked at how exposure to interactive TV-based music and art therapy could assist in reducing suicidal thoughts of secondary school female children who survived abduction in Nigeria. A quasi-experiment was carried out in three randomly selected secondary schools in Northern Nigeria. The study sample comprised 470 students divided into three groups to form control group 235, art therapy group 118 and music therapy group 117. Results suggest that participants exposed to interactive TV-based art therapy and music therapy reported a lower score for suicidal ideation compared to the control group that was not exposed to any form of therapy aside from routine clinic checkups. Specifically, those exposed to interactive TV-based art therapy reported a lesser suicidal ideation score than the music and the control group. We recommend the introduction of interactive TV-based music therapy and art therapy in reducing suicidal ideation among children that survived kidnapping in Nigeria.

"Keep up the messages, sometimes it was a lifesaver": Effects of cultural adaptation on a suicide prevention clinical trial in American Indian/Alaska Native communities

Suicide disproportionately affects many American Indian/Alaska Native (AI/AN) communities. Caring Contacts is one of the few suicide prevention interventions with demonstrated success in diverse populations, but its acceptability and effectiveness have not been evaluated in AI/AN communities. Using community-based participatory research (Phase 1), we conducted focus groups and semi-structured interviews with AI/AN adults, healthcare providers, and leaders in four communities to improve study design and maximize intervention acceptability and effectiveness for implementation in a randomized controlled trial (Phase 2). This paper describes how adaptations made during Phase 1 affected the acceptability, fit, and responsiveness of the study features to the communities' needs. Acceptability of the study procedures and materials in this community appears to be high, with 92% of participants indicating the initial assessment interview was a positive experience. Broadening eligibility criteria with regard to age and possession of a cellular device resulted in the recruitment of an additional 48% and 46% of participants, respectively. Inclusion of locally-informed methods of self-harm allowed us to capture a wider range of suicidal behavior than would have otherwise been identified. Clinical trials would benefit from community-engaged, cultural adaptation studies with populations in which the interventions would eventually be applied.

Caring Texts, a strength-based, suicide prevention trial in 5 native communities: Research design and methods

BACKGROUND

Despite their intrinsic strengths and resilience, some American Indian and Alaska Native (AI/AN) communities experience among the highest rates of suicide of any racial and ethnic group. Caring Contacts is one of the only interventions shown to reduce suicide in clinical trials, but it has not been tested in AI/AN settings.

OBJECTIVE

To compare the effectiveness of Enhanced Usual Care (control) to Enhanced Usual Care augmented with a culturally adapted version of Caring Contacts (intervention) for reducing suicidal ideation, suicide attempts, and suicide-related hospitalizations.

METHODS

We are implementing a single blind randomized controlled trial of Caring Contacts in five AI/AN communities across the country (South Dakota, Montana, Oklahoma, and Alaska). Eligible participants have to be (1) actively suicidal or have made a suicide attempt within the past year; (2) at least 18 years of age; (3) AI/AN; (4) able to speak and read English; (5) able to participate voluntarily; (6) willing to be contacted by text, email or postal mail; and (7) able to provide consent. Following consent and baseline assessment, participants are randomized to receive either Enhanced Usual Care alone, or Enhanced Usual Care with 12 months (25 messages) of culturally adapted Caring Contacts. Follow-up assessments are conducted at 12 and 18 months.

CONCLUSIONS

If effective, this study of Caring Contacts will inform programs to reduce suicide in the study communities as well as inform future research on Caring Contacts in other tribal settings. Modifications to continue the trial during the COVID-19 pandemic are discussed.

Adaptation of an Emotional Stroop Test for Screening of Suicidal Ideation in Portugal

Cognitive instruments, especially those with emotional components, may be useful to address the limitations of self-report scales commonly used to assess suicidal ideation. The aim of this study was to develop an emotional Stroop test for screening suicidal ideation in Portugal. The project was developed in five phases using different samples for each phase. The first two phases were focused on the formulation of the potential words that would compose the slides. For this purpose, five biology teachers (neutral slide) and five mental health professionals (positive and negative slides) were invited to help choose the words that were most representative for each slide. The third phase validated the words defined in the previous phase. In this phase, 300 university students participated (M_age = 21.66; SD = 3.67; 68% female). They rated the words on a Likert scale in terms of their frequency of use, familiarity, level of understanding, and degree of image evocation. In the fourth phase, the researchers developed the complete version of the test, which consists of three slides with neutral, positive, and negative emotional stimuli, consecutively. Finally, in the fifth phase, we validated the final version of the test through a comparative study between a clinical group and a non-clinical group, each one composed by 50 participants (M_age = 32; SD = 9.70; 55% female). Results indicated that the clinical group demonstrated significantly higher scores for depression and suicidal ideation and lower scores for the three Stroop tasks. Words related to negative emotions were strongly correlated with suicidal ideation. Finally, the three Stroop slides explained 74.1% of the variance in suicidal ideation. These findings suggest that this test can be a viable complementary measure in the psychological assessment of suicide ideation, and intervention in the field of suicide prevention in Portugal.

Suicide attempt endophenotypes: Latent profiles of child and adolescent aggression and impulsivity differentially predict suicide attempt in females

Suicide is a leading cause of death in young adulthood. Identifying early prevention targets to reduce later suicide is a public health priority. Impulsivity and aggression in early childhood may represent actionable early prevention candidate endophenotypes for later suicidal behavior. Our objective is to to understand the association of aggression and impulsivity trajectories with mental health outcomes to inform future prevention efforts. Participants were part of a longitudinal cohort of a preventative intervention trial (n = 597) and predominantly Black. They were assessed for aggressive and impulsive behaviors yearly in 1st-3rd and 6th-12th grades, and provided mental health data via self-report beginning in 6th grade. Longitudinal latent profiles of aggressive and impulsive behaviors were derived for males and females and used to determine whether profiles was associated with lifetime suicide attempt and meeting diagnostic criteria for major depressive disorder. Two impulsivity and aggression classes were found for males, characterized by low behaviors or moderate to high behaviors across development. Three classes were found for females, one of which was characterized by an undulating pattern of behaviors. For females, the class of severe behaviors was associated with significant risk of suicide attempt (Wald = 6.01, p = 0.05). No relationship was found for males or for MDD diagnosis. An endophenotype model of impulsivity and aggression in predicting later suicide attempt was supported in females, but not males. Results underscore the importance of evaluating sex differences in suicide research and the potential identification of females at risk for later suicidal behavior in school settings.

Suicide Biomarkers to Predict Risk, Classify Diagnostic Subtypes, and Identify Novel Therapeutic Targets: 5 Years of Promising Research

BACKGROUND

Suicide is a global health crisis. However, no objective biomarkers of suicide risk currently exist, and self-reported data can be unreliable, which limits prediction, diagnostic, and treatment efforts. Reliable biomarkers that can differentiate between diagnostic subgroups, predict worsening symptoms, or suggest novel therapeutic targets would be extremely valuable for patients, researchers, and clinicians.

METHODS

MEDLINE was searched for reports published between 2016 and 2021 using search terms (suicid*) AND (biomarker*) OR (indicat*). Reports that compared biomarkers between suicidal ideation, suicide attempt, death from suicide, or any suicide subgroup against other neuropsychiatric disorders were included. Studies exclusively comparing suicidal behavior or death from suicide with healthy controls were not included to ensure that biomarkers were specific to suicide and not other psychopathology.

RESULTS

This review summarizes the last 5 years of research into suicide-associated biomarkers and provides a comprehensive guide for promising and novel biomarkers that encompass varying presentations of suicidal ideation, suicide attempt, and death by suicide. The serotonergic system, inflammation, hypothalamic-pituitary-adrenal axis, lipids, and endocannabinoids emerged as the most promising diagnostic, predictive, and therapeutic indicators.

CONCLUSIONS

The utility of diagnostic and predictive biomarkers is evident, particularly for suicide prevention. While larger-scale studies and further in-depth research are required, the last 5 years of research has uncovered essential biomarkers that could ultimately improve predictive strategies, aid diagnostics, and help develop future therapeutic targets.

Predicting the Transition From Suicidal Ideation to Suicide Attempt Among Sexual and Gender Minority Youths

OBJECTIVE

Sexual and gender minority youths are more likely to consider, attempt, and die by suicide than are heterosexual and cisgender youths, yet little is known about how to predict future attempts or transitions from suicidal thoughts to behaviors. Additionally, adaptive measurement of psychopathology is a promising approach that may help characterize risk in this population. This study examined the validity of the Computerized Adaptive Test for Suicide Scale (CAT-SS) in predicting suicide attempts and the transition from suicidal ideation to attempt.

METHODS

The CAT-SS was administered to participants of two ongoing cohort studies of sexual and gender minority adolescents and young adults (N=1,006). Survival analyses examined longitudinal associations between CAT-SS scores and time to suicide attempt. Analyses were conducted for the full sample and stratified by those with and without a history of suicidal ideation, with comparisons between adaptive and static measures of depressive symptoms.

RESULTS

The CAT-SS predicted future suicide attempts in the overall sample (hazard ratio [HR]=1.34, 95% confidence interval [CI]=1.03-1.74). Among youths without a history of suicidal ideation, social support reduced the risk for attempts (HR=0.66, 95% CI=0.45-0.96). Among youths with a history of ideation, predictors of the transition from suicidal thoughts to attempts included baseline CAT-SS score (HR=1.51, 95% CI=1.06-2.15) and victimization (HR=2.48, 95% CI=1.10-5.59).

CONCLUSIONS

Risk and protective factors for suicide attempts differed between youths with and without a history of suicidal thoughts. The CAT-SS had validity in predicting future risk of the sample overall and of youths with suicidal ideation.

Association between early menarche and suicidal behaviors in Korean girl adolescents

Early menarche can be the socio-psychological problems. We studied the association between early menarche and suicidal risk behaviors among South Korean girl adolescents using national-wide data.Web-based self-report data from 2006 to 2015 the Korea Youth Risk Behavior Web-based Survey data were used in this study. Menarche status was divided into an "early menarche" group (at <12 years of age) versus "not early" menarche group (at ≥12 years of age).Participants with adolescent girls with early menarche group showed a higher prevalence of substance use, higher levels of stress, poorer self-rated health status, unhappier perceiveness, more frequent depressed mood, inter-sexual kissing or petting, inter-sexual intercourse, homosexual kissing or petting, being the victim or the assailant of sexual assaults, sexual transmitted diseases experience, pregnancy, and abortion experience than the not early menarche group. Adolescent girls with early menarche who had suicidal ideation (25.4% vs 22.2%, P < .001), suicidal plans (4.1% vs 2.6%, P < .001), and suicidal attempts (6.8% vs 5.2%, P < .001) were higher than that in the adolescent girls with not early menarche. A multivariate analysis after adjusting revealed that the odds ratios for suicidal ideation, plans, and attempts were 1.07 (95% confidence interval [CI]: 1.05-1.10), 1.35 (95% CI: 1.28-1.41), and 1.13 (95% CI: 1.09-1.18), respectively.Adolescent girl with early menarche was associated with suicidal behaviors.

Peer Connectedness and Pre-Existing Social Reward Processing Predicts U.S. Adolescent Girls' Suicidal Ideation During COVID-19

There is major concern about the impact of the COVID-19 pandemic on adolescent suicidal ideation (SI) and peer relationships. We investigated (1) rates of SI and (2) the extent to which peer connectedness and pre-existing neural activation to social reward predicted SI during the initial stay-at-home orders of the pandemic (April-May 2020) in a longitudinal sample of adolescent girls (N = 93; Mage  = 15.06; 69% White non-Hispanic). Daily diary and fMRI methods were used to assess peer connectedness and neural activation to social reward, respectively. Nearly 40% of girls endorsed SI during the initial stay-at-home orders. Greater peer connectedness and neural responsivity to anticipated social reward were associated with a reduced odds of SI during the pandemic among girls.

Associations between insecure attachment styles to parents and suicidal ideation in adolescents with depression

Objective

Suicidal ideation and depressive symptoms are often interrelated in clinical settings. Insecure attachment may be a risk factor for suicidal ideation in depressed adolescents. To our knowledge, this study is the first to examine the association between self-reported insecure attachment styles to both parents and suicidal ideation in a clinical sample of adolescents with depression.

Methods

Fifty clinically depressed adolescents (13-17 years, 84% girls) completed self-reported measures of suicidal ideation, depressive symptoms, and attachment style to parents.

Results

There was a statistically significant bivariate association between higher levels of attachment anxiety in relation to mothers and fathers and higher levels of suicidal ideation. When attachments to both parents were included in the same multivariate model, only attachment anxiety to the mother was significantly associated with the level of suicidal ideation. Self-reported depressive symptoms remained significantly associated with the level of suicidal ideation in all analyses. Younger adolescents with attachment anxiety reported higher levels of suicidal ideation than older adolescents.

Conclusion

Conclusions about directionality and causality of associations between insecure attachment and suicidal ideation are limited due to the cross-sectional design. Our findings suggest that attachment anxiety in relation to the mother and father is associated with increased levels of suicidal ideation. Implication of these findings for treatment selection is discussed.

Differentiating Adolescent Suicide Attempters and Ideators: A Classification Tree Analysis of Risk Behaviors

PURPOSE

Although many youth consider suicide, only a subset act on suicidal thoughts and attempt suicide. The objective of this study was to identify patterns of risk factors that differentiate adolescents who experienced suicidal thoughts from those who attempted suicide.

METHODS

This study analyzed data from the 2013, 2015, and 2017 National Youth Risk Behavior Surveys. Classification tree analysis was used to identify combinations of health risk behaviors and demographic factors that improved the identification of past-year suicide attempts among adolescents with past-year suicide ideation or planning (overall n = 7,493).

RESULTS

Forty percent of the past-year ideators attempted suicide in the same period. The best-performing tree included three variables and defined four subgroups. Youth characterized by heroin use and past-year physical fights were at a strikingly high risk of being attempters (78%). Youth who had experienced rape were also likely to be attempters (58%), whereas those who had endorsed none of these three variables were relatively less likely to be attempters (29%). Overall, the tree's classification accuracy was modest (area under the curve = .65).

CONCLUSIONS

This study advances previous research by identifying notable constellations of risk behaviors that accounted for adolescents' transition from suicidal ideation to behavior. However, even with many health risk behavior variables, a large sample, and a multidimensional analytic approach, the overall classification of suicide attempters among ideators was limited. Implications for future research are discussed.

Five Profiles of Adolescents at Elevated Risk for Suicide Attempts: Differences in Mental Health Service Use

OBJECTIVE

Adolescents at risk for suicide are highly heterogeneous in terms of psychiatric and social risk factors, yet there has been little systematic research on risk profiles, which would facilitate recognition and the matching of patients to services. Our primary study aims were to identify latent class profiles of adolescents with elevated suicide risk, and to examine the association of these profiles with mental health service use (MHSU).

METHOD

Participants were 1,609 adolescents from the Emergency Department Screen for Teens at Risk for Suicide (ED-STARS) cohort. Participants completed baseline surveys assessing demographics, MHSU, and suicide risk. Telephone follow-up interviews were conducted at 3 months to assess suicide attempts. Participants met pre-established baseline criteria for suicide risk.

RESULTS

Using latent class analysis, we derived 5 profiles of elevated suicide risk with differing patterns of eight risk factors: history of multiple suicide attempts, past-month suicidal ideation, depression, alcohol and drug misuse, impulsive-aggression, and sexual and physical abuse. In comparison to adolescents who did not meet baseline criteria for suicide risk, each profile was associated with increased risk of a suicide attempt within 3 months. The MHSU was lowest for adolescents fitting profiles with previous (but no recent) suicidal thoughts and behavior, and for adolescents from racial and ethnic minority groups.

CONCLUSION

Adolescents at elevated risk for suicide present to emergency departments with differing profiles of suicide risk. MHSU varies across these profiles and by race/ethnicity, indicating that targeted risk recognition and treatment linkage efforts may be necessary to reach some adolescents at risk.

Detecting risk of suicide attempts among Chinese medical college students using a machine learning algorithm

BACKGROUND

Suicide has become one of the most prominent concerns for public health and wellness; however, detecting suicide risk factors among individuals remains a big challenge. The aim of this study was to develop a machine learning algorithm that could effectively and accurately identify the probability of suicide attempts in medical college students.

METHODS

A total of 4,882 medical students were enrolled in this cross-sectional study. Self-report data on socio-demographic and clinical characteristics were collected online via website or through the widely used social media app, WeChat. 5-fold cross validation was used to build a random forest model with 37 suicide attempt predictors. Model performance was measured for sensitivity, specificity, area under the curve (AUC), and accuracy. All analyses were conducted in MATLAB.

RESULTS

The random forest model achieved good performance [area under the curve (AUC) = 0.9255] in predicting suicide attempts with an accuracy of 90.1% (SD = 0.67%), sensitivity of 73.51% (SD = 2.33%) and specificity of 91.68% (SD = 0.82%).

LIMITATION

The participants are primarily females and medical students.

CONCLUSIONS

This study demonstrates that the random forest model has the potential to predict suicide attempts among medical college students with high accuracy. Our findings suggest that application of the machine learning model may assist in improving the efficiency of suicide prevention.

Prevalence and associated factors of suicide among hospitalized schizophrenic patients

BACKGROUND

Previous studies found several factors associated with suicide in schizophrenic patients, such as age, sex, education level, history of suicide attempts, psychotic symptoms, social factors, and substance abuse. However, there might be some additional factors that were not considered in previous studies but may be correlated with a greater likelihood of suicide attempts, such as medication and treatment.

AIM

To investigate the prevalence of suicide attempts and identify the risk of suicidality in hospitalized schizophrenia patients.

METHODS

This is a cross-sectional study of schizophrenic patients admitted to a psychiatric hospital who were 18 years of age or more. The outcomes and possible suicide risk factors in these patients were collated. The current suicide risk was evaluated using the mini-international neuropsychiatric interview module for suicidality and categorized as none (0 points), mild (1-8 points), moderate (9-16 points), or severe (17 or more points). This study used ordinal logistic regression to assess the association of potential risk factors with the current suicide risk in schizophrenic patients.

RESULTS

Of 228 hospitalized schizophrenia patients, 214 (93.9%) were included in this study. The majority (79.0%) of patients were males. Females appeared to have a slightly higher suicidality risk than males, with borderline significance. With regard to the current suicide risk assessed with the mini-international neuropsychiatric interview, 172 (80.4%) schizophrenic patients scored zero, 20 (9.4%) had a mild risk, 8 (3.7%) had a moderate risk, and 14 (6.5%) had a severe risk. The total prevalence of current suicide risk in these schizophrenic patients was 19.6%. Based on multivariable ordinal logistic regression analysis with backward elimination, it was found that younger age, a current major depressive episode, receiving fluoxetine or lithium carbonate in the previous month, or a relatively higher Charlson comorbidity index score were all significantly and independently associated with a higher level of suicide risk.

CONCLUSION

The prevalence rate of suicide attempts in schizophrenia is high. Considering risk factors in routine clinical assessments, environmental manipulations and adequate treatment might prevent or decrease suicide in these patients.

Evidence-Based Interventions for Youth Suicide Risk

PURPOSE OF REVIEW

To review and discuss recent advances in evidence-based interventions (EBIs) for youth suicide risk.

RECENT FINDINGS

There is a growing body of research on the effectiveness of interventions targeting suicidal ideation and behavior among adolescents. Dialectical Behavioral Therapy-Adolescent has shown effectiveness across two independent randomized controlled trials (RCTs). Several other interventions have shown effectiveness in only one trial and are in need of replication. New interventions are also being developed that incorporate developments in technology and adaptive intervention designs. It is recommended that future research focus on strategies for engaging underserved youth with interventions, consider the broader needs of youth living in poverty, and further tailor interventions to subgroups with distinct risk profiles. Limited EBIs exist for preadolescents, despite evidence for an increasing rate of suicidal behavior for these youth. Several interventions for youth suicide risk are highly promising, but further investigation is necessary. EBIs that are effective for preadolescents are needed, and greater efforts to tailor interventions for distinct subgroups of youth at risk are recommended.

Management of Suicidal Adolescents Presenting to the Emergency Department

Background:

Increasingly, adolescents are presented to hospital emergency departments with suicidal ideation (SI) and depression. Even among those who come in with other complaints, depression and SI are common. Emergency personnel are placed in the default position of providing care for these patients, but often lack sufficient knowledge and skills to do this effectively.

Objective:

The aim of this paper is to offer guidance to emergency personnel and describe goals and strategies for screening and brief interventions.

Method:

We review risk factors, assessment tools and evidence-based interventions that can be utilized by mental health professionals working in EDs and by ED staff in the absence of mental health professionals.

Conclusion:

Emergency departments can serve a critical role in risk management and treatment of adolescent depression and suicidal ideation. All patients presenting to the ED should be screened for current and past depression and suicidal ideation or attempts. Brief interventions can be delivered in the ED that can increase the likelihood that patients will receive follow- up care.

Predicting 3-month risk for adolescent suicide attempts among pediatric emergency department patients

BACKGROUND

The incidence of adolescent suicide is rising in the United States, yet we have limited information regarding short-term prediction of suicide attempts. Our aim was to identify predictors of suicide attempts within 3-months of an emergency department (ED) visit.

METHODS

Adolescents, ages 12-17, seeking health care at 13 pediatric EDs (Pediatric Emergency Care Applied Research Network) and one Indian Health Service Hospital in the United States were consecutively recruited. Among 10,664 approached patients, 6,448 (60%) were enrolled and completed a suicide risk survey. A subset of participants (n = 2,897) was assigned to a 3-month telephone follow-up, and 2,104 participants completed this follow-up (73% retention). Our primary outcome was a suicide attempt between the ED visit and 3-month follow-up.

RESULTS

One hundred four adolescents (4.9%) made a suicide attempt between enrollment and 3-month follow-up. A large number of baseline predictors of suicide attempt were identified in bivariate analyses. The final multivariable model for the full sample included the presence of suicidal ideation during the past week, lifetime severity of suicidal ideation, lifetime history of suicidal behavior, and school connectedness. For the subgroup of adolescents who did not report recent suicidal ideation at baseline, the final model included only lifetime severity of suicidal ideation and social connectedness. Among males, the final model included only lifetime severity of suicidal ideation and past week suicidal ideation. For females, the final model included past week suicidal ideation, lifetime severity of suicidal ideation, number of past-year nonsuicidal self-injury (NSSI) incidents, and social connectedness.

CONCLUSIONS

Results indicate that the key risk factors for adolescent suicide attempts differ for subgroups of adolescents defined by sex and whether or not they report recent suicidal thoughts. Results also point to the importance of school and social connectedness as protective factors against suicide attempts.

Suicide Attempts and Course of Suicidal Ideation among Puerto Rican Early Adolescents

Suicidal behavior increases substantially during early adolescence, a critical understudied developmental period. This study reports on the prevalence of suicidal ideation, suicide attempts, and course of suicidal ideation among Puerto Rican early adolescents, a high-risk group for suicidal behavior in adulthood. Gender differences and the prospective association of psychiatric disorders with course of suicidal ideation are examined. Participants were 1228 Puerto Rican adolescents (ages 10-13 at wave 1; 48% female) and parents, selected through probability-based sampling, assessed yearly across three waves. Adolescents and parents reported via Diagnostic Interview Schedule for Children-IV about 12-month suicide attempts and suicidal ideation (further categorized as never present, onset, recurrence, and remission), mood and anxiety disorders; parents reported on disruptive disorders. Over the three waves, 9.5% early adolescents thought about suicide and 2.1% attempted suicide. In adjusted multinomial regression models, compared to those with never present suicidal ideation, female gender was related to onset of suicidal ideation (OR = 2.60; 95% CI, 1.22-5.55). Disruptive disorders were related to onset (OR = 5.80; 95% CI, 2.06-16.32) and recurrence of suicidal ideation (OR = 5.07, 95% CI, 1.14-22.47), mood disorders were related to remission (OR = 14.42, 95% CI, 3.90-53.23), and anxiety disorders to onset of suicidal ideation (OR = 3.68, 95% CI, 1.75-7.73). Our findings inform strategies tailored for early adolescents. To address onset of suicidal ideation, prevention should focus on girls and those with anxiety or disruptive disorders. When ideation is recurrent, interventions oriented to reduce disruptive behavior and its consequences may help achieve remission.

Predicting future self-harm or suicide in adolescents: a systematic review of risk assessment scales/tools

OBJECTIVE

This systematic review aimed to evaluate the ability of risk tools to predict the future episodes of suicide/self-harm in adolescents.

DESIGN

Systematic review.

DATA SOURCES

MEDLINE, EMBASE, CINAHL and PsycINFO were searched from inception to 3 March 2018.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

Cohort studies, case-control studies and randomised controlled trials of adolescents aged 10-25 who had undergone risk assessment in a clinical setting following an episode of self-harm were included.

DATA EXTRACTION AND SYNTHESIS

Two independent reviewers extracted data and assessed risk of bias. Data were grouped by tool and narrative synthesis undertaken, with studies appraised using a checklist combining the QUIPS (Quality In Prognosis Studies) and QUADAS-2 (Quality Assessment of Diagnostic Accuracy Studies) tools.

RESULTS

Of the 17 137 articles initially identified, 11 studies evaluating 10 separate tools were included. The studies varied in setting, population and outcome measure. The majority of the studies were rated as having an unclear risk of bias, and meta-analysis was not possible due to high variability between studies.The ability of the tools to correctly identify those adolescents going on to make a self-harm/suicide attempt ranged from 27% (95% CI 10.7% to 50.2%) to 95.8% (95% CI 78.9% to 99.9%). A variety of metrics were provided for 1-10 points increases in various tools, for example, odds and HRs.

CONCLUSIONS

This systematic review is the first to explore the use of assessment tools in adolescents. The predictive ability of these tools varies greatly. No single tool is suitable for predicting a higher risk of suicide or self-harm in adolescent populations.

Assessment tools of immediate risk of self-harm and suicide in children and young people: A scoping review

There are increasing numbers of children presenting to paediatric hospital settings in mental health crisis. Typically, non-mental health professionals are responsible for the initial assessment of these children and are required to identify immediate physical and emotional health needs. To ensure the safety of these children, immediate risk of suicide and self-harm should be assessed. However, no standardized assessment tool is used in clinical practice, and for those tools that are used, their validity and reliability is unclear. A scoping review was conducted to identify the existing assessment tools of immediate self-harm and suicide risk. Searches of electronic databases and relevant reference lists were undertaken. Twenty-two tools were identified and most assessed acute risk of suicide with only four tools incorporating a self-harm assessment. The tools varied in number of items (4-146), subscales (0-11) and total scores (16-192). Half incorporated Likert-type scales, and most were completed via self-report. Many tools were subject to limited psychometric testing, and no single tool was valid or reliable for use with children presenting in mental health crisis to non-mental health settings. As such, a clinically appropriate, valid and reliable tool that assesses immediate risk of self-harm and suicide in paediatric settings should be developed.

Rethinking suicides as mental accidents: Towards a new paradigm

BACKGROUND

Since its beginnings, suicide research has made great progress in terms of empirical findings. However, in contrast to empirical knowledge, the theoretical understanding of suicides has shown only minimal progress. Missing interdisciplinary bridges and the lack of a unifying paradigm have been major obstacles. This paper examines the starting points for a rethink.

METHODS

In the first step, we identified major challenges in suicide research, which have been obstructing a better understanding. In the second step, we determined a new concept of suicide that is highly compatible with epidemiological results and meets the requirements of interdisciplinary usability. In the third step, the implications of this paradigm were explored by relating it to two process typologies, the one characterizing the temporal dynamics of suicide processes, and the other representing risk mechanisms / factors occurring at different stages of suicide processes.

RESULTS

Since suicides are rare events and often appear to be "rash acts", they can be conceived of as mental accidents or, more precisely, as failures to withstand temporary suicide impulses. This paradigm is suitable for synchronously implementing different personal, psychopathological, societal and situational perspectives. It applies to a high proportion of suicides and works well when being exposed to different typologies of suicide processes.

CONCLUSIONS

The mental accident paradigm provides an interdisciplinary starting point in suicidology that offers new perspectives in research, prediction and prevention.

Identification of suicidal behavior among psychiatrically hospitalized adolescents using natural language processing and machine learning of electronic health records

Objective

The rapid proliferation of machine learning research using electronic health records to classify healthcare outcomes offers an opportunity to address the pressing public health problem of adolescent suicidal behavior. We describe the development and evaluation of a machine learning algorithm using natural language processing of electronic health records to identify suicidal behavior among psychiatrically hospitalized adolescents.

Methods

Adolescents hospitalized on a psychiatric inpatient unit in a community health system in the northeastern United States were surveyed for history of suicide attempt in the past 12 months. A total of 73 respondents had electronic health records available prior to the index psychiatric admission. Unstructured clinical notes were downloaded from the year preceding the index inpatient admission. Natural language processing identified phrases from the notes associated with the suicide attempt outcome. We enriched this group of phrases with a clinically focused list of terms representing known risk and protective factors for suicide attempt in adolescents. We then applied the random forest machine learning algorithm to develop a classification model. The model performance was evaluated using sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy.

Results

The final model had a sensitivity of 0.83, specificity of 0.22, AUC of 0.68, a PPV of 0.42, NPV of 0.67, and an accuracy of 0.47. The terms mostly highly associated with suicide attempt clustered around terms related to suicide, family members, psychiatric disorders, and psychotropic medications.

Conclusion

This analysis demonstrates modest success of a natural language processing and machine learning approach to identifying suicide attempt among a small sample of hospitalized adolescents in a psychiatric setting.

Emerging trends in adolescent suicide prevention research

A comprehensive public health strategy for adolescent suicide prevention includes upstream prevention strategies, strategies for risk recognition, and services for those at risk. Interpersonal trauma and substance use are important prevention targets as each is associated with risk for suicide attempts. Multiple prevention programs target these factors; however, the Family Check-Up, designed to reduce substance use and behavioral problems, also has been associated with reduced suicide risk. Several youth screening instruments have shown utility, and a large-scale trial is underway to develop a computerized adaptive screen. Similarly, several types of psychotherapy have shown promise, and sufficiently powered studies are underway to provide more definitive results. The climbing youth suicide rate warrants an urgent, concerted effort to develop and implement effective prevention strategies.

Suicide Risk Screening in Healthcare Settings: Identifying Males and Females at Risk

Suicide is the tenth leading cause of death in the United States, accounting for more than 42,000 deaths in 2014. Although this tragedy cuts across groups defined by age, gender, race/ethnicity, and geographic location, it is striking that nearly four times as many males as females die by suicide in the U.S. We describe the current regulations and recommendations for suicide risk screening in healthcare systems and also describe the aspirational goal of "Zero Suicide," put forth by the National Action Alliance for Suicide Prevention. We then provide information about suicide risk screening tools and steps to take when a patient screens positive for suicide risk. Given the substantially higher suicide rate among males than females, we argue that it is important to consider how we could optimize suicide risk screening strategies to identify males at risk and females at risk. Further research is needed to accomplish this goal. It is recommended that we consider multi-factorial suicide risk screens that incorporate risk factors known to be particularly important for males as well as computerized, adaptive screens that are tailored for the specific risk considerations of the individual patient, male or female. These strategies are not mutually exclusive. Finally, universal suicide risk screening in healthcare settings, especially primary care, specialty medical care, and emergency department settings, is recommended.

Life is Precious: A Community-Based Program to Reduce Suicidal Behavior in Latina Adolescents

Latina adolescents have high rates of suicidal behavior. Life is Precious (LIP), a community-based program in New York City, helps adolescents and families address risk factors facing Latinas. Participants are assessed for suicidal ideation, depressive and other psychiatric symptoms, and family functioning, at program entry and every 4 months during participation. Demographic characteristics and suicide attempts are also tracked. In the study period, there were no attempted or completed suicides in this high-risk population. Suicidal ideation, depressive symptoms, anger, and posttraumatic stress symptoms decreased significantly during participation. The LIP model shows promise for helping to address suicidal risk factors facing Latinas. However, in the absence of a comparison group, participants' improvement may be due to their engagement in mental health treatment more generally, or to the passage of time, rather than specifically to LIP. Nevertheless, as very little is known about how to address risk factors unique to Latina adolescents, these early findings may be of interest to the community serving Latina adolescents and the lessons may be of interest to programs serving adolescents from other racial/ethnic groups. Future research should develop comparison groups and test LIP implementation in other settings.

Predictive Validity of the Columbia-Suicide Severity Rating Scale for Short-Term Suicidal Behavior: A Danish Study of Adolescents at a High Risk of Suicide

Using the Columbia-Suicide Severity Rating Scale (C-SSRS), we examined the predictive and incremental predictive validity of past-month suicidal behavior and ideation for short-term suicidal behavior among adolescents at high risk of suicide. The study was conducted in 2014 on a sample of 85 adolescents (90.6% females) who participated at follow-up (85.9%) out of the 99 (49.7%) baseline respondents. All adolescents were recruited from a specialized suicide-prevention clinic in Denmark. Through multivariate logistic regression analyses, we examined whether baseline suicidal behavior predicted subsequent suicidal behavior (actual attempts and suicidal behavior of any type, including preparatory acts, aborted, interrupted and actual attempts; mean follow-up of 80.8 days, SD = 52.4). Furthermore, we examined whether suicidal ideation severity and intensity incrementally predicted suicidal behavior at follow-up over and above suicidal behavior at baseline. Actual suicide attempts at baseline strongly predicted suicide attempts at follow-up. Baseline suicidal ideation severity and intensity did not significantly predict future actual attempts over and above baseline attempts. The suicidal ideation intensity items deterrents and duration were significant predictors of subsequent actual attempts after adjustment for baseline suicide attempts and suicidal behavior of any type, respectively. Suicidal ideation severity and intensity, and the intensity items frequency, duration and deterrents, all significantly predicted any type of suicidal behavior at follow-up, also after adjusting for baseline suicidal behavior. The present study points to an incremental predictive validity of the C-SSRS suicidal ideation scales for short-term suicidal behavior of any type among high-risk adolescents.

Belongingness and Burdensomeness in Adolescents: Slovene Translation and Validation of the Interpersonal Needs Questionnaire

The Interpersonal Needs Questionnaire (INQ) for assessing thwarted belongingness (TB) and perceived burdensomeness (PB) has not been validated with community adolescents. We translated and administered the INQ to 307 Slovenian adolescents twice over 2-3 months and found that the 15-item version (INQ-15) did not fit without modification. TB and PB scales correlated with concurrent and later suicide ideation and lifetime suicide attempt history. The latent PB factor was associated with concurrent and later ideation controlling for TB, age, gender, depressive symptoms, binge drinking, and peer victimization. Suicide ideation and binge drinking were independently related to attempt history. Assessing and intervening on PB and binge drinking may be promising approaches to suicide prevention with community adolescents.

Identification of At-Risk Youth by Suicide Screening in a Pediatric Emergency Department

The pediatric emergency department (ED) is a critical location for the identification of children and adolescents at risk for suicide. Screening instruments that can be easily incorporated into clinical practice in EDs to identify and intervene with patients at increased suicide risk is a promising suicide prevention strategy and patient safety objective. This study is a retrospective review of the implementation of a brief suicide screen for pediatric psychiatric ED patients as standard of care. The Ask Suicide Screening Questions (ASQ) was implemented in an urban pediatric ED for patients with psychiatric presenting complaints. Nursing compliance rates, identification of at-risk patients, and sensitivity for repeated ED visits were evaluated using medical records from 970 patients. The ASQ was implemented with a compliance rate of 79 %. Fifty-three percent of the patients who screened positive (237/448) did not present to the ED with suicide-related complaints. These identified patients were more likely to be male, African American, and have externalizing behavior diagnoses. The ASQ demonstrated a sensitivity of 93 % and specificity of 43 % to predict return ED visits with suicide-related presenting complaints within 6 months of the index visit. Brief suicide screening instruments can be incorporated into standard of care in pediatric ED settings. Such screens can identify patients who do not directly report suicide-related presenting complaints at triage and who may be at particular risk for future suicidal behavior. Results have the potential to inform suicide prevention strategies in pediatric EDs.

Psychopathology profiles of acutely suicidal adolescents: Associations with post-discharge suicide attempts and rehospitalization

BACKGROUND

Suicidal adolescents are heterogeneous, which can pose difficulties in predicting suicidal behavior. The Youth Self-Report (YSR) psychopathology profiles predict the future onset of psychopathology and suicide-related outcomes. The present study examined the prevalence and correlates of YSR psychopathology profiles among suicidal adolescents and prospective associations with post-discharge rates of suicide attempts and psychiatric rehospitalization.

METHODS

Participants were acutely suicidal, psychiatrically hospitalized adolescents (N=433 at baseline; n=355 at follow-up) who were enrolled in a psychosocial intervention trial during hospitalization. Psychopathology profiles were assessed at baseline. Suicide attempts and rehospitalization were assessed for up to 12 months following discharge.

RESULTS

Latent profile analysis identified four psychopathology profiles: subclinical, primarily internalizing, and moderately and severely dysregulated. At baseline, profiles differed by history of non-suicidal self-injury (NSSI) and multiple suicide attempts (MA) as well as severity of suicide ideation, hopelessness, depressive symptoms, anxiety symptoms, substance abuse, and functional impairment. The dysregulation profiles predicted suicide attempts within 3 months post-discharge. The internalizing profile predicted suicide attempts and rehospitalization at 3 and 12 months.

LIMITATIONS

This study's participants were enrolled in a randomized trial and were predominantly female, which limit generalizability. Additionally, only a history of NSSI was assessed.

CONCLUSIONS

The dysregulation profile was overrepresented among suicidal youth and associated with impairment in several domains as well as suicide attempts shortly after discharge. Adolescents with a severe internalizing profile also reported adverse outcomes throughout the study period. Psychopathology profiles warrant further examination in terms of their potential predictive validity in relation to suicide-related outcomes.

Menarche, menstrual problems and suicidal behavior in Chinese adolescents

BACKGROUND

Menarche is the first menstrual cycle. Menstrual problems, such as dysmenorrheal menorrhagia, oligomenorrhea, and irregular cycle are common in female adolescents. This research aims to examine the associations between age at menarche and menstrual problems and suicidal behavior among Chinese female adolescents.

METHODS

An epidemiological survey of 5831 female adolescents from eight high schools of three counties of Shandong province, China, was conducted. A self-administered paper-and-pencil questionnaire was used to collect information. Logistic regression analyses were used to examine the association between menstruation and suicidality.

RESULTS

The mean age of the sample was 15.02 (SD=1.44) years. Of the sample, 5,231 (90.0%) had experienced their first menstrual cycle, and 23.2%, 10.4%, and 4.5% of the sample reported having had suicidal ideation, plan and attempt, respectively. In multivariate models, menarche at ≤11 years was associated with increased risk of suicidal ideation (OR=1.41, 95%CI: 1.10-1.81) and menarche at 12 years was associated with suicide plan (OR=1.23, 95%CI: 1.00-1.51). Irregular menstrual cycle was significantly associated with increased risk of suicidal ideation (OR=1.40, 95%CI: 1.05-1.86) and menstrual period less than or equal to 4 days was significantly associated with increased risk of suicide plan (OR=1.32, 95%CI: 1.06-1.66).

LIMITATIONS

This cross-sectional study cannot establish the causal directions between menstrual problems and suicidality in adolescents.

CONCLUSIONS

Our study suggests that earlier menarche, irregular menstrual cycle and short menstrual period are associated with suicidal behavior in female adolescents. Further research is warranted to examine the causal relationship between menstrual problems and suicidal behavior in adolescents.

Riesgo suicida según la tríada cognitiva negativa, ideación, desesperanza y depresión

Objetivo: establecer la relación entre ideación suicida, desesperanza, tríada cognitiva negativa y depresión, como evidencia del modelo cognitivo del riesgo suicida. Método: estudio empírico-analítico con diseño descriptivo, correlacional y comparativo. Las variables fueron medidas con los inventarios BDI-II, PANSI e ITC y la escala BHS. La muestra final estuvo constituida por 90 personas de ambos sexos, con una media de edad de 24,2 años (DT = 8,65 años) pertenecientes a diversos niveles socioeconómicos, con estudios universitarios, principalmente. Resultados: se encontraron correlaciones estadísticamente significativas entre ideación suicida, desesperanza, depresión y la tríada cognitiva negativa. Las diferencias fueron significativas entre los grupos depresivos y no depresivos, con grandes efectos para las tres variables cognitivas. Interpretación y conclusiones: estos resultados constituyen nueva evidencia del modelo cognitivo planteado acerca de la relación entre las variables depresión, tríada cognitiva negativa, ideación suicida y desesperanza, tal como se ha propuesto en distintas revisiones sobre cognición negativa y suicidio. Se analizaron las limitaciones del estudio en cuanto el reducido tamaño muestral y las diferencias entre sexos para depresión ante estresores específicos, y las variaciones por grupos de edades en el riesgo suicida de los jóvenes.

Brief report: Suicidal ideation in adolescent girls: Impact of race

In the present study, we examine the unique and interactive effects of race (African American or European American) and depression on suicidal ideation, controlling for poverty, within a representative sample of adolescent girls. A community sample of 2450 girls (43.9% African American) participating in the longitudinal Pittsburgh Girls Study (PGS) was interviewed annually about depression symptoms and suicidal ideation, from ages 10-15 years. Caregivers reported on the girls' racial/ethnic background and the family's receipt of public assistance. Race and depression scores explained unique variance in suicidal ideation; receipt of public assistance did not. Endorsement and recurrence of suicidal ideation was more likely for African American than European American girls: there was a nearly two-fold increase in the likelihood of reporting frequent thoughts of death or suicide as a function of race. Of the 255 girls reporting recurrent suicidal ideation, 65.9% were African American. An interaction effect between race and depression symptoms was observed, such that African American girls were more likely to report suicidal ideation at lower levels of depression severity. The findings indicate that race is a critical factor for understanding, preventing, and treating suicidal ideation in girls.

Protective Role of Religious Involvement Against Depression and Suicidal Ideation Among Youth with Interpersonal Problems

This study examined religious involvement-private religious practices (PRP), organizational religiousness (OR), and religious support (RS)-in relation to depressive symptoms and suicidal ideation (SI) and its protective role, considering youths' school and parent-family connectedness. Youth, ages 12-15 (n = 161), were screened for peer victimization, bullying perpetration, and low social connectedness, and assessed for depressive symptoms, SI, school connectedness, parent-family connectedness, and religious involvement. Results indicated PRP and RS were associated with lower levels of depressive symptoms; PRP and OR were associated with less SI. Controlling for connectedness, PRP remained associated with less SI only. Results suggest the importance of considering religious involvement as a target of youth depression and suicide prevention interventions.

Double RASS cutpoint accurately diagnosed suicidal risk in females with long-term conditions attending the emergency department compared to their male counterparts

BACKGROUND

Suicidal risk is often unrecognized in emergency department (ED). We aimed to assess its prevalence in patients with long-term conditions (LTCs) attending an ED and to test whether gender differences influence suicidal risk assessment, using the diagnostic accuracy properties of the Risk Assessment Suicidality Scale (RASS).

METHODS

The RASS was administered to 349 patients with diabetes, COPD and rheumatic diseases visiting an ED. The MINI interview was used as the criterion standard. ROC curve analysis was performed to determine the optimal RASS cutpoint for suicidal risk separately for males and females. Somatic (PHQ-15) and depressive (PHQ-9) symptoms were also assessed and factors associated with suicidal risk across gender were determined in hierarchical regression models.

RESULTS

The prevalence of suicidal risk according to the MINI was 22.9%; 16.6% of patients were at low, 5.1% at moderate, and 0.9% at high risk. At an optimal cutpoint of 270, RASS had 81.3% sensitivity and 81.8% specificity. The optimal RASS cutpoint for females (340) was double the cutpoint for males (175). Somatic symptom burden was associated with suicidal risk in both sexes but it became non-significant after depressive symptoms were taken into account; suicidal risk was also associated with history of depression in females and lower income in males.

CONCLUSION

There is a high prevalence of suicidal risk in patients with LTCs attending the ED. As the optimal RASS cutpoint for females was double the cutpoint for males, clinicians should bear in mind gender differences when assessing for suicidal risk in the ED.

Use of the Modified Emotional Stroop Task to Detect Suicidality in College Population

This cross-sectional study investigated the usefulness of the emotional Stroop task (EST) as a behavioral marker for suicidal behaviors in a college population. Eight hundred twenty college students were asked to perform on the EST and to respond to suicide-related self-report measures. The results indicated that past suicide attempters were slower in responding to the word "suicide" as compared to nonattempters, and female past attempters showed more delayed response when their most recent attempt was made in the past 12 months. We did not find evidence that the EST could outperform the traditional self-report measures.

A prospective examination of the interpersonal-psychological theory of suicidal behavior among psychiatric adolescent inpatients

The challenge of identifying suicide risk in adolescents, and particularly among high-risk subgroups such as adolescent inpatients, calls for further study of models of suicidal behavior that could meaningfully aid in the prediction of risk. This study examined how well the Interpersonal-Psychological Theory of Suicidal Behavior (IPTS)--with its constructs of thwarted belongingness (TB), perceived burdensomeness (PB), and an acquired capability (AC) for lethal self-injury--predicts suicide attempts among adolescents (N = 376) 3 and 12 months after hospitalization. The three-way interaction between PB, TB, and AC, defined as a history of multiple suicide attempts, was not significant. However, there were significant 2-way interaction effects, which varied by sex: girls with low AC and increasing TB, and boys with high AC and increasing PB, were more likely to attempt suicide at 3 months. Only high AC predicted 12-month attempts. Results suggest gender-specific associations between theory components and attempts. The time-limited effects of these associations point to TB and PB being dynamic and modifiable in high-risk populations, whereas the effects of AC are more lasting. The study also fills an important gap in existing research by examining IPTS prospectively.

When self-reliance is not safe: associations between reduced help-seeking and subsequent mental health symptoms in suicidal adolescents

The majority of suicidal adolescents have no contact with mental health services, and reduced help-seeking in this population further lessens the likelihood of accessing treatment. A commonly-reported reason for not seeking help is youths’ perception that they should solve problems on their own. In this study, we explore associations between extreme self-reliance behavior (i.e., solving problems on your own all of the time), help-seeking behavior, and mental health symptoms in a community sample of adolescents. Approximately 2150 adolescents, across six schools, participated in a school-based suicide prevention screening program, and a subset of at-risk youth completed a follow-up interview two years later. Extreme self-reliance was associated with reduced help-seeking, clinically-significant depressive symptoms, and serious suicidal ideation at the baseline screening. Furthermore, in a subset of youth identified as at-risk at the baseline screening, extreme self-reliance predicted level of suicidal ideation and depressive symptoms two years later even after controlling for baseline symptoms. Given these findings, attitudes that reinforce extreme self-reliance behavior may be an important target for youth suicide prevention programs. Reducing extreme self-reliance in youth with suicidality may increase their likelihood of appropriate help-seeking and concomitant reductions in symptoms.

Non-suicidal self-injury and suicidal ideation as predictors of suicide attempts in adolescent girls: a multi-wave prospective study

Although both suicide ideation (SI) and non-suicidal self-injury (NSSI) are known risk factors for suicidal behavior, few longitudinal studies have examined whether having a history of one or both of these factors prospectively predicts increased risk for suicide attempts. According to the theory of acquired capability for suicide, engagement in NSSI may reduce inhibitions around self-inflicted violence, imparting greater risk for suicide attempts among those with SI than would be observed in those with SI who do not have a history of NSSI. We used prospective data from the Pittsburgh Girls Study, a large community sample, to compare groups of girls reporting no SI or NSSI, SI only, or both NSSI and SI between early to late adolescence on any lifetime or recent suicide attempts in late adolescence and early adulthood. As compared to girls with no SI or NSSI history and those with only an SI history, girls with a history of both NSSI and SI were significantly more likely to subsequently report both lifetime and recent suicide attempts. Results are consistent with the acquired capability theory for suicide and suggest that adolescent girls who have engaged in NSSI and also report SI represent a particularly high-risk group in need of prevention and intervention efforts.

Identifying adolescents at highly elevated risk for suicidal behavior in the emergency department

OBJECTIVE

The feasibility and concurrent validity of adolescent suicide risk screening in medical emergency departments (EDs) has been documented. The objectives of this short-term prospective study of adolescents who screened positive for suicide risk in the ED were: 1) to examine adolescents' rate of suicidal behavior during the 2 months following their ED visits and compare it with reported rates for psychiatric samples; and 2) to identify possible predictors of acute risk for suicidal behavior in this at-risk sample.

METHOD

Participants were 81 adolescents, ages 14-19 years, seeking services for psychiatric and nonpsychiatric chief complaints, who screened positive for suicide risk because of recent suicidal ideation, a suicide attempt, and/or depression plus alcohol or substance misuse. A comprehensive assessment of suicidal behavior, using the Columbia-Suicide Severity Rating Scale, was conducted at baseline and 2 month follow-up.

RESULTS

Six adolescents (7.4%) reported a suicide attempt and 15 (18.5%) engaged in some type of suicidal behavior (actual, aborted, or interrupted suicide attempt; preparatory behavior) during the 2 months following their ED visit. These rates suggest that this screen identified a high-risk sample. Furthermore, adolescents who screened positive for suicidal ideation and/or attempt plus depression and alcohol/substance misuse were most likely to engage in future suicidal behavior (38.9%).

CONCLUSIONS

In this study, use of a higher screen threshold (multiple suicide risk factors) showed promise for identifying highly elevated acute risk for suicidal behavior.

Predicting Future Suicide Attempts Among Adolescent and Emerging Adult Psychiatric Emergency Patients

The purpose of this study was to longitudinally examine specific characteristics of suicidal ideation in combination with histories of suicide attempts and non-suicidal self-injury (NSSI) to best evaluate risk for a future attempt among high-risk adolescents and emerging adults. Participants in this retrospective medical record review study were 473 (53% female; 69% Caucasian) consecutive patients, ages 15 to 24 years (M=19.4 years) who presented for psychiatric emergency services during a 9-month period. These patients' medical records, including a clinician-administered Columbia-Suicide Severity Rating Scale, were coded at the index visit and at future visits occurring within the next 18 months. Logistic regression models were used to predict suicide attempts during this period. Socioeconomic status, suicidal ideation severity (i.e., intent, method), suicidal ideation intensity (i.e., frequency, controllability), a lifetime history of suicide attempt, and a lifetime history of NSSI were significant independent predictors of a future suicide attempt. Suicidal ideation added incremental validity to the prediction of future suicide attempts above and beyond the influence of a past suicide attempt, whereas a lifetime history of NSSI did not. Sex moderated the relationship between the duration of suicidal thoughts and future attempts (predictive for male patients but not female). Results suggest value in incorporating both past behaviors and current thoughts into suicide risk formulation. Furthermore, suicidal ideation duration warrants additional examination as a potential critical factor for screening assessments evaluating suicide risk among high-risk samples, particularly for male patients.

Longitudinal trajectories of suicidal ideation and subsequent suicide attempts among adolescent inpatients

A period of particularly high risk for suicide attempts among adolescent inpatients is within 12 months after discharge. However, little is known about longitudinal trajectories of suicidal ideation in this high-risk group and how these relate to posthospitalization suicide attempts and rehospitalizations. Our objectives were to identify these trajectories and examine their relationships with posthospitalization psychiatric crises. We also examined predictors of trajectory group membership. Participants (N = 376; ages 13-17; 72% female) were assessed at hospitalization and 3, 6, and 12 months later. Trajectory groups, and their predictors, were identified with latent class growth modeling. We used logistic regression to examine associations between trajectory groups and likelihood of suicide attempts and rehospitalization, controlling for attempt history. Three trajectory groups were identified: (a) subclinical ideators (31.6%), (b) elevated ideators with rapidly declining ideation (57.4%), and (c) chronically elevated ideators (10.9%). Adolescents in the chronically elevated ideation group had 2.29, confidence interval (CI) [1.08, 4.85], p = .03, and 4.15, CI [1.65, 10.44], p < .01, greater odds of attempting suicide and 3.23, CI [1.37, 7.69], p = .01, and 11.20, CI [4.33, 29.01], p < .001, greater odds of rehospitalization relative to rapidly declining and subclinical groups, respectively. Higher baseline hopelessness was associated with persisting suicidal ideation. Results suggest that suicidal ideation severity at hospitalization may not be an adequate marker for subsequent suicidal crises. It is important to identify adolescents vulnerable to persisting suicidal ideation, as they are at highest risk of psychiatric crises. Addressing hopelessness may facilitate faster declines in ideation after hospitalization. Results also highlight a need for consistent monitoring of these adolescents' suicidal ideation after discharge.
