Adolescents Who Do Not Endorse Risk via the Patient Health Questionnaire Before Self-Harm or Suicide

Importance

Given that the Patient Health Questionnaire (PHQ) item 9 is commonly used to screen for risk of self-harm and suicide, it is important that clinicians recognize circumstances when at-risk adolescents may go undetected.

Objective

To understand characteristics of adolescents with a history of depression who do not endorse the PHQ item 9 before a near-term intentional self-harm event or suicide.

Design, Setting, and Participants

This was a retrospective cohort study design using electronic health record and claims data from January 2009 through September 2017. Settings included primary care and mental health specialty clinics across 7 integrated US health care systems. Included in the study were adolescents aged 13 to 17 years with history of depression who completed the PHQ item 9 within 30 or 90 days before self-harm or suicide. Study data were analyzed September 2022 to April 2023.

Exposures

Demographic, diagnostic, treatment, and health care utilization characteristics.

Main Outcome(s) and Measure(s)

Responded "not at all" (score = 0) to PHQ item 9 regarding thoughts of death or self-harm within 30 or 90 days before self-harm or suicide.

Results

The study included 691 adolescents (mean [SD] age, 15.3 [1.3] years; 541 female [78.3%]) in the 30-day cohort and 1024 adolescents (mean [SD] age, 15.3 [1.3] years; 791 female [77.2%]) in the 90-day cohort. A total of 197 of 691 adolescents (29%) and 330 of 1024 adolescents (32%), respectively, scored 0 before self-harm or suicide on the PHQ item 9 in the 30- and 90-day cohorts. Adolescents seen in primary care (odds ratio [OR], 1.5; 95% CI, 1.0-2.1; P = .03) and older adolescents (OR, 1.2; 95% CI, 1.0-1.3; P = .02) had increased odds of scoring 0 within 90 days of a self-harm event or suicide, and adolescents with a history of inpatient hospitalization and a mental health diagnosis had twice the odds (OR, 2.0; 95% CI, 1.3-3.0; P = .001) of scoring 0 within 30 days. Conversely, adolescents with diagnoses of eating disorders were significantly less likely to score 0 on item 9 (OR, 0.4; 95% CI, 0.2-0.8; P = .007) within 90 days.

Conclusions and Relevance

Study results suggest that older age, history of an inpatient mental health encounter, or being screened in primary care were associated with at-risk adolescents being less likely to endorse having thoughts of death and self-harm on the PHQ item 9 before a self-harm event or suicide death. As use of the PHQ becomes more widespread in practice, additional research is needed for understanding reasons why many at-risk adolescents do not endorse thoughts of death and self-harm.

Impulsivity profiles across five harmonized longitudinal childhood preventive interventions and associations with adult outcomes

This study aimed to parse between-person heterogeneity in growth of impulsivity across childhood and adolescence among participants enrolled in five childhood preventive intervention trials targeting conduct problems. In addition, we aimed to test profile membership in relation to adult psychopathologies. Measurement items representing impulsive behavior across grades 2, 4, 5, 7, 8, and 10, and aggression, substance use, suicidal ideation/attempts, and anxiety/depression in adulthood were integrated from the five trials (N = 4,975). We applied latent class growth analysis to this sample, as well as samples separated into nonintervention (n = 2,492) and intervention (n = 2,483) participants. Across all samples, profiles were characterized by high, moderate, low, and low-increasing impulsive levels. Regarding adult outcomes, in all samples, the high, moderate, and low profiles endorsed greater levels of aggression compared to the low-increasing profile. There were nuanced differences across samples and profiles on suicidal ideation/attempts and anxiety/depression. Across samples, there were no significant differences between profiles on substance use. Overall, our study helps to inform understanding of the developmental course and prognosis of impulsivity, as well as adding to collaborative efforts linking data across multiple studies to better inform understanding of developmental processes.

Suicidal Thoughts and Behaviors Among Children and Adolescents With Autism Spectrum Disorder

This survey study uses data from the Mental Health and Suicidal Behaviors Questionnaire to examine the age at onset of suicidal thoughts and behaviors among children and adolescents aged 8 to 17 years who have been diagnosed with autism spectrum disorder (ASD).

Prevalence and Correlates of Opioid-Involved Suicides in Maryland

OBJECTIVE

Involvement of opioids in suicides has doubled during the past two decades, worsening a major public health concern. This study examined the characteristics of opioid-involved suicides.

METHODS

The sample of decedents (N = 12,038) in Maryland between 2006 and 2020 was used to compare the characteristics of opioid-involved suicides (n = 947) with suicides not involving opioids (n = 6,896) and accidental opioid deaths (n = 4,125). Direct comparisons were then made between opioid-involved suicides with and without the additional presence of non-opioid substances.

RESULTS

Opioid-involved suicides were significantly more likely than suicides not involving opioids to occur among those aged 18-64 years, non-Hispanic Whites, and unemployed or disabled individuals. Opioid-involved suicides were more likely than accidental opioid deaths to occur among females, those aged <18 years, non-Hispanic Whites, and employed individuals. Of all suicides involved opioids, 45% involved other non-opioid substances. Polysubstance opioid suicides were significantly more likely than suicides involving opioids only to occur among non-Hispanic Whites.

CONCLUSIONS

Significant differences were observed in the demographic groups most at risk for opioid-involved suicide than other suicide or accidental opioid death. Among opioid-involved suicides, polysubstance involvement also represents a distinct group. These findings may enhance the targeting of prevention efforts.

A Linguistic Analysis of Instagram Captions Between Adolescent Suicide Decedents and Living Controls

Background: Suicide rates continue to rise for adolescents in the United States. 62% of teenagers use Instagram, and as technology and research in this domain advance, social media posts could provide insights into near-term adolescent risk states and could inform new strategies for suicide prevention. This study analyzed language in captions of teenagers' Instagram accounts in the 3 months before suicide and compared caption language to matched living controls. Method: The study identified 89 teenagers who died by suicide using obituaries and news reports and 89 matched living control teenagers. Linguistic Inquiry and Word Count (LIWC) software was used to test for differences in specific language categories across linguistic, psychological, and topical categories (e.g., word count, tone, grammar, affective, cognitive, social, punctuation marks, etc.). Results: Significant differences between suicide decedents and living controls were found. Adolescent suicide decedents used more words per sentence, more references to sadness, male individuals, drives, and leisure and fewer verbs and references to they, affiliation, achievement, and power. Limitations: Methodological limitations include the use of only public accounts, small sample size, occasional short posts, and lack of adjustment for multiple testing. Conclusion: Although the sample size is relatively small and only included youth with public accounts, we identified differences in Instagram caption language between adolescents who died by suicide as compared to living controls.

Examining the unique impacts of Potentially Traumatic Experiences (PTE) and discrimination events on Post-Traumatic Stress Disorder (PTSD) and suicidal thoughts and behaviors among Multiracial/ethnic adults in the United States

BACKGROUND

Suicide and PTSD are pressing public health issues in the US, with discrimination and potentially traumatic experiences (PTEs) influencing mental health. However, the unique effects of these factors on Multiracial/ethnic adults' PTSD and suicidal thoughts/behaviors (STB) are not thoroughly researched.

METHODS

Using a cross-sectional design, an online survey was conducted (N = 1012) from October to December 2022. Multivariable logistic regression models analyzed relationships between PTEs, discriminatory events, and mental health outcomes, accounting for sociodemographics.

RESULTS

After adjusting for demographics, exposure to PTEs and discrimination correlated with heightened odds of PTSD and STB. Individual lifetime discrimination experiences and specific PTEs demonstrated varying associations with STB and PTSD. The study underscores discrimination's relevance as a risk factor.

LIMITATIONS

The study's cross-sectional nature restricts causality or temporality interpretations. Moreover, the convenience sample of English-speaking online participants might not be reflective of all Multiracial/ethnic US adults.

CONCLUSIONS

Findings underscore PTEs and discrimination's interconnectedness in Multiracial/ethnic mental health outcomes. Discrimination might pose similar risks to PTEs. Acknowledging discrimination as potential precursors for PTSD and STB aids accurate diagnosis and effective treatment planning. Incorporating racial/ethnic discrimination and traumatic experiences into PTSD conceptualization and assessment is pivotal. This knowledge informs tailored interventions and mental health education for this population.

Childhood Factors Associated With Unnatural Death Through Midadulthood

Importance

Life expectancy is decreasing in the US. Without national efforts to address factors that support policies and programs directed at children living in areas of concentrated poverty, life expectancy will likely continue to decline while costs and suffering associated with unnatural deaths will increase.

Objective

To identify which childhood factors are associated with death from unnatural causes through midadulthood.

Design, Setting, and Participants

For this cohort study, longitudinal data on childhood characteristics came from a group-randomized intervention trial implemented in Baltimore City Public Schools, Baltimore, Maryland (baseline 1985-1986; all students entering first grade were selected to participate at age 6 years). Participants were followed up to midadulthood with a National Death Index search through December 31, 2020. Data analysis was performed from February to May 2023.

Exposures

Exposures included individual factors (ie, sociodemographic characteristics, teacher-reported aggressive behavior, self-reported depression, anxiety, early alcohol and cannabis use, and assaultive violence exposure), family and peer factors (ie, household structure and education level, deviant peer affiliation, and parental monitoring), and neighborhood factors (ie, rates of neighborhood assault and public assistance).

Main Outcomes and Measures

The main outcome was unnatural death, defined as death due to unintentional injury, suicide, and homicide. A National Death Index search ascertained participants who died by age 41 to 42 years and cause of death. Multivariable Cox proportional hazards models were used to identify whether the exposures were independently associated with future mortality by unnatural causes.

Results

The initial trial included 2311 children, and longitudinal data were available for 2180 participants (median [IQR] age in first grade, 6.3 [6.0-6.5] years; 1090 female [50.0%]; 1461 Black [67.0%]; 1168 received free or reduced lunch in first grade [53.6%]). A total of 111 male participants (10.2%) and 29 female participants (2.7%) died; among those who died, 96 male participants (86.5%) and 14 female participants (48.3%) died of unnatural causes. Two factors remained significantly associated with mortality from unnatural causes: female sex was associated with reduced risk (hazard ratio, 0.13; 95% CI, 0.08-0.22), and neighborhood public assistance was associated with increased risk (hazard ratio, 1.89; 95% CI, 1.09-3.30).

Conclusions and Relevance

In this urban population-based cohort study, no modifiable risk factors of mortality at the level of the individual (eg, depression or anxiety and substance use) or the family (eg, household education level) were identified. However, the degree of neighborhood poverty in early childhood was significantly associated with death by unnatural causes in early adulthood, suggesting that economic policies are needed to advance health equity in relation to premature mortality.

An examination of the psychometric properties of the Patient Health Questionnaire-9 (PHQ-9) in a Multiracial/ethnic population in the United States

Depression and suicide are significant public health issues. The Patient Health Questionnaire-9 (PHQ-9) is commonly used to assess for symptoms of depression, but its psychometric properties within Multiracial/ethnic populations remains uncertain. In a study involving 1,012 English-speaking Multiracial/ethnic participants from the United States (US), the PHQ-9 showed strong internal consistency (α = 0.93) and supported a one-factor structure. No measurement variance was observed between Non-White and White/Non-White Multiracial/ethic subgroups. PHQ-2, with a cutoff of ≥3, identified fewer depression cases than PHQ-9 (32% vs. 40%), with sensitivities of 75-99% and specificities of 74-96%; a cutoff of ≥2 missed fewer cases. Item performance of the ninth PHQ-9 question, addressing thoughts of death or self-harm, varied across generations with younger generations more likely to endorse thoughts of death or self-harm at any level of symptom severity. The findings suggest the PHQ-9 demonstrated adequate reliability within a population of Multiracial/ethnic adults in the US; however, the use of the 9th item of the PHQ-9 may not be adequate for identifying individuals at risk for suicidal thoughts and/or behaviors, particularly for older Multiracial/ethnic adults. The lower sensitivity of the PHQ-2 with a ≥ 3 cutoff suggests a cutoff of ≥2 may be preferable to miss fewer cases of depression.

Mental health and Multiracial/ethnic adults in the United States: a mixed methods participatory action investigation

Introduction

Addressing gaps in the integration of justice, diversity, equity, and inclusion (J-DEI) in public health research and practice, this study investigates the mental health of Multiracial and multiethnic adults in the United States (U.S.). A rapidly growing racial/ethnic group in the U.S., Multiracial and multiethnic populations are often excluded or underrepresented in standard public health research and practice, and little is known about their mental health or associated risk and protective factors.

Methods

To investigate this knowledge gap, an electronic cross-sectional survey was conducted in two waves in 2022, pulling from various community sources, with 1,359 respondents in total. Complementing this, seventeen semi-structured interviews were performed with a subset of survey participants. Data were analyzed using a mix of statistical methods and staged hybrid inductive-deductive thematic analysis.

Results

Findings indicate over half of the participants endorsed at least one mental health concern with prevalence of anxiety, depression, post-traumatic stress disorder, and suicidal thoughts and behaviors surpassing available national estimates. Exposure to trauma, discrimination, and microaggressions were found to play a significant role in these outcomes. Conversely, strong social support and strong ethnic identity emerged as protective factors. Qualitative insights brought forward the challenges faced by individuals in navigating bias and stigma, especially in the context of mental health care. Despite these barriers, emerging themes highlighted resilience, the importance of secure identity formation, and the critical role of community and cultural support.

Conclusions

The marked prevalence of mental health concerns among Multiracial and multiethnic populations emphasizes the pressing need for tailored interventions and inclusive research methodologies. Recognizing and addressing the unique challenges faced by these communities is imperative in driving mental health equity in the U.S. The findings advocate for community-engaged practices, interdisciplinary collaborations, and the importance of addressing mental health challenges with cultural sensitivity, particularly in historically oppressed and marginalized groups. Future efforts must focus on refining these practices, ensuring that public health initiatives are genuinely inclusive and equitable.

Identifying Causal Risk Factors for Self-Harm Among Adolescents With U.S. Child Protective Services Contact

OBJECTIVES

To estimate effects of potentially modifiable risk factors for self-harm among adolescents in the Child Protective Services (CPS) system.

METHODS

Data came from the National Survey of Child and Adolescent Well-being, a nationally representative longitudinal survey. Candidate risk factors included child's feelings of worthlessness, the presence of supportive adults in the child's life, and parental psychological aggression. Propensity score weighting (PSW) was used to control for observed confounders, and the average effect of experiencing the risk factor among those who did was estimated using weighted logistic regression.

RESULTS

Odds ratios for self-harm comparing youth with low and high parental psychological aggression to none were 0.93 (0.35-2.45) and 1.25 (0.55-2.82), respectively. The OR for feelings of worthlessness was 1.73 (0.70-4.27), and for supportive adults 0.58 (0.28-1.19). The combination of survey and propensity score weights may have affected statistical power.

CONCLUSIONS

Preventing self-harm in adolescents requires a multifaceted approach given the existing evidence base and lack of strong associations with individual risk factors. Fostering supportive relationships with adults merits future research given the observed, non-significant 42% reduction in odds of self-harm among CPS involved youth who had a supportive relationship with an adult, compared to those who did not.

Correlates of Informant Discrepancies in Self-Harm Among Youth Involved in Child Protective Services

Youth involved with child protective services (CPS) are at elevated risk for engaging in self-harm. Participation in interventions or treatments that may reduce youths' self-harm behaviors often depends on the accurate reporting of their self-injurious behaviors. However, informants often disagree on the presence or severity of self-harm engagement, making the identification of youth in need of treatment more challenging. The current study aims to characterize discrepancies between youth and caregiver reports of children's self-harm among a sample of youth with a history of CPS involvement, and to identify factors (e.g., demographics, youth and caregiver psychological impairments, aspects of the caregiving environment) associated with these discrepancies. Participants (N = 258) were drawn from a large, nationally representative sample of youth under the age of 18 (mean age = 13.8) and their caregivers who were investigated by CPS. Multinomial logistic regressions were used to examine correlates of discrepancies in caregiver and youth reports of youth self-harm. Results indicated that 10% of caregiver-child dyads agreed on children's engagement in self-harm. In 33% of cases, only the child reported self-harm and in 57% of cases, only the caregiver reported youth self-harm. Being a biological caregiver, child female sex, higher levels of internalizing symptoms; higher post-traumatic stress disorder (PTSD) symptoms; and greater caregiver alcohol use was associated with a lower likelihood of caregivers reporting self-harm only. Older child age; lower externalizing symptoms; higher PTSD symptoms, and greater levels of caregiver emotional security and structure were linked to lower odds of children reporting self-harm only. These results underscore important factors to consider when assessing self-harm among youth involved with CPS and have potential implications for practice guidelines in this population.

Examining the Feasibility of Implementing Digital Mental Health Innovations Into Hospitals to Support Youth in Suicide Crisis: Interview Study With Young People and Health Professionals

BACKGROUND

Hospitals are insufficiently resourced to appropriately support young people who present with suicidal crises. Digital mental health innovations have the potential to provide cost-effective models of care to address this service gap and improve care experiences for young people. However, little is currently known about whether digital innovations are feasible to integrate into complex hospital settings or how they should be introduced for sustainability.

OBJECTIVE

This qualitative study explored the potential benefits, barriers, and collective action required for integrating digital therapeutics for the management of suicidal distress in youth into routine hospital practice. Addressing these knowledge gaps is a critical first step in designing digital innovations and implementation strategies that enable uptake and integration.

METHODS

We conducted a series of semistructured interviews with young people who had presented to an Australian hospital for a suicide crisis in the previous 12 months and hospital staff who interacted with these young people. Participants were recruited from the community nationally via social media advertisements on the web. Interviews were conducted individually, and participants were reimbursed for their time. Using the Normalization Process Theory framework, we developed an interview guide to clarify the processes and conditions that influence whether and how an innovation becomes part of routine practice in complex health systems.

RESULTS

Analysis of 29 interviews (n=17, 59% young people and n=12, 41% hospital staff) yielded 4 themes that were mapped onto 3 Normalization Process Theory constructs related to coherence building, cognitive participation, and collective action. Overall, digital innovations were seen as a beneficial complement to but not a substitute for in-person clinical services. The timing of delivery was important, with the agreement that digital therapeutics could be provided to patients while they were waiting to be assessed or shortly before discharge. Staff training to increase digital literacy was considered key to implementation, but there were mixed views on the level of staff assistance needed to support young people in engaging with digital innovations. Improving access to technological devices and internet connectivity, increasing staff motivation to facilitate the use of the digital therapeutic, and allowing patients autonomy over the use of the digital therapeutic were identified as other factors critical to integration.

CONCLUSIONS

Integrating digital innovations into current models of patient care for young people presenting to hospital in acute suicide crises is challenging because of several existing resource, logistical, and technical barriers. Scoping the appropriateness of new innovations with relevant key stakeholders as early as possible in the development process should be prioritized as the best opportunity to preemptively identify and address barriers to implementation.

Association of a History of Incarceration and Solitary Confinement with Suicide-Related Outcomes in a General Population Sample from Two U.S. Cities

OBJECTIVES

To evaluate whether a history of incarceration was associated with increased odds of suicidal ideation and suicide attempts, and to determine if this association was further strengthened when combined with a history of solitary confinement.

METHODS

We collected cross-sectional data from a general population sample in New York City and Baltimore in March 2017. Participants were categorized based on their history of incarceration and solitary confinement: (1) no incarceration, (2) incarceration-only, and (3) incarceration plus solitary confinement. We compared these three groups, utilizing hierarchical adjustments for sociodemographic factors and adverse childhood experiences. Missing data were accounted for utilizing multiple imputation via chained equation.

RESULTS

A total of 1221 individuals were analyzed. Those who experienced both incarceration and solitary confinement consistently had higher odds of suicidal ideation (OR, 2.80; 95% CI, 1.43 to 5.48) and suicide attempts (OR, 6.98; 95% CI, 2.77 to 17.61) than never incarcerated individuals. Those who experienced incarceration without solitary confinement had higher odds of suicide attempts (OR, 3.77; 95% CI, 1.35 to 10.56) than never incarcerated individuals, whereas this association was not evident for suicidal ideation. Solitary confinement increased the odds of suicidal ideation even compared to incarceration without solitary confinement (OR, 2.71; 95% CI, 1.09 to 6.74).

CONCLUSIONS

Our findings support the need to address the higher likelihood of suicide-related outcomes among those in contact with the criminal justice system, and to consider alternatives to solitary confinement.

Psychosis Symptom Trajectories Across Childhood and Adolescence in Three Longitudinal Studies: An Integrative Data Analysis with Mixture Modeling

Psychotic-like experiences (PLEs) are common throughout childhood, and the presence of these experiences is a significant risk factor for poor mental health later in development. Given the association of PLEs with a broad number of mental health diagnoses, these experiences serve as an important malleable target for early preventive interventions. However, little is known about these experiences across childhood. While these experiences may be common, longitudinal measurement in non-clinical settings is not. Therefore, in order to explore longitudinal trajectories of PLEs in childhood, we harmonized three school-based randomized control trials with longitudinal follow-up to identify heterogeneity in trajectories of these experiences. In an integrative data analysis (IDA) using growth mixture modeling, we identified three latent trajectory classes. One trajectory class was characterized by persistent PLEs, one was characterized by high initial probabilities but improving across the analytic period, and one was characterized by no reports of PLEs. Compared to the class without PLEs, those in the improving class were more likely to be male and have higher levels of aggressive and disruptive behavior at baseline. In addition to the substantive impact this work has on PLE research, we also discuss the methodological innovation as it relates to IDA. This IDA demonstrates the complexity of pooling data across multiple studies to estimate longitudinal mixture models.

Effectiveness of teen Mental Health First Aid in Improving Teen-to-Teen Support Among American Adolescents

BACKGROUND

teen Mental Health First Aid (tMHFA) is an Australian school-based universal program for grade 10 to 12 students. tMHFA teaches teens how to recognize and respond to a peer in crisis or experiencing mental health concerns.

METHODS

Schools implementing tMHFA in 2019 and 2020 were propensity score matched, yielding a sample of instructors (n = 130) and students (n = 1915) in 44 high schools in 24 American states. Effectiveness and acceptability were assessed with student surveys at baseline and after implementation.

RESULTS

There were significant findings for primary outcomes, including improved helpful first aid intentions (Cohen ds = 0.57 to 0.58), confidence supporting a peer (ds = 0.19 to 0.31); the number of adults rated as helpful (ds = 0.37 to 0.44); and reductions in stigmatizing beliefs (ds = 0.21 to 0.40) and "harmful first aid intentions" (ds = 0.11 to 0.42). Instructors and students rated the program favorably with students sharing improvements on their recognition and responses to mental health problems and crises.

CONCLUSION

tMHFA is an effective, feasible, and scalable training program for increasing mental health literacy and decreasing mental health stigma in adolescents in the short term, consistent with trials of tMHFA in Australian adolescents.

A Guide for Schools on Student-Directed Suicide Prevention Programs Eligible for Implementation under the STANDUP Act, a Rapid Review and Evidence Synthesis

This review evaluates the strength of evidence for school-based mental health and suicide prevention programs that meet the legal eligibility criteria of the Suicide Training and Awareness Nationally Delivered for Universal Prevention Act of 2021 (STANDUP Act). Included studies were aggregated by program and a program's overall body of evidence was evaluated using the LEGEND system. Requirements for implementation were also documented. We identified 29 studies, which, when aggregated, encompassed 12 unique programs that meet the statute's evidence-based criteria. All four outcomes described in the statute were measured, with help-seeking being the most commonly measured. Two programs were assigned a high level of evidence in decreasing suicidal thoughts and behaviors. The findings serve as a resource for school officials in identifying evidence-based mental health and suicide prevention programs and understanding the resources needed for implementation.

Demographic predictors of emergency service utilization patterns in youth at risk of suicide

OBJECTIVE

To explore demographic predictors of Emergency Department (ED) utilization among youth with a history of suicidality (i.e., ideation or behaviors).

METHODS

Electronic health records were extracted from 2017 to 2021 for 3094 8-22 year-old patients with a history of suicidality at an urban academic medical center ED in the Mid-Atlantic. Logistic regression analyses were used to assess for demographic predictors of ED utilization frequency, timing of subsequent visits, and reasons for subsequent visits over a 24-month follow-up period.

RESULTS

Black race (OR = 1.45, 95% CI = 1.11-1.92), Female sex (OR = 1.59, 95% CI = 1.26-2.03), and having Medicaid insurance (OR = 1.71, 95% CI = 1.37-2.14) were associated with increased utilization, while being under 18 was associated with lower utilization (<12: OR = 0.38, 95% CI = 0.26-0.56; 12-18: OR = 0.47, 95% CI = 0.35-0.63). These demographics were also associated with ED readmission within 90 days, while being under 18 was associated with a lower odds of readmission.

CONCLUSIONS

Among patients with a history of suicidality, those who identify as Black, young adults, patients with Medicaid, and female patients were more likely to be frequent utilizers of the ED within the 2 years following their initial visit. This pattern may suggest inadequate health care access for these groups, and a need to develop better care coordination with an intersectional focus to facilitate utilization of other health services.

Family environment and polygenic risk in the bipolar high-risk context

Background

The interaction of polygenic risk (PRS) and environmental effects on development of bipolar disorder (BD) is understudied, as are high-risk offspring perceptions of their family environment (FE). We tested the association of offspring-perceived FE in interaction with BD-PRS on liability for BD in offspring at high or low familial risk for BD.

Methods

Offspring of a parent with BD (oBD; n = 266) or no psychiatric disorders (n = 174), aged 12-21 at recruitment, participated in the US and Australia. Empirically-derived profiles of FE classified offspring by their perceived levels of familial cohesion, flexibility, and conflict. Offspring BD-PRS were derived from Psychiatric Genomics Consortium BD-GWAS. Lifetime DSM-IV bipolar disorders were derived from the Schedule for Affective Disorders and Schizophrenia for School-Aged Children. We used a novel stepwise approach for latent class modeling with predictors and distal outcomes.

Results

Fifty-two offspring were diagnosed with BD. For those with well-functioning FE (two-thirds of the sample), higher BD-PRS tracked positively with liability for BD. However, for those with high-conflict FEs, the relationship between BD-PRS and liability to BD was negative, with highest risk for BD observed with lower BD-PRS. In exploratory analyses, European-ancestry offspring with BD had elevated history of suicidal ideation in high-conflict FE compared to well-functioning-FE, and of suicide attempt with low-BD-PRS and high-conflict FE.

Conclusions

The data suggest that the relationship of BD-PRS and offspring liability for BD differed between well-functioning versus high-conflict FE, potentially in line with a multifactorial liability threshold model and supporting future study of and interventions improving family dynamics.

Cultural Adaptation of the teen Mental Health First Aid (tMHFA) Program from Australia to the USA

teen Mental Health First Aid (tMHFA) is an evidence-based program developed in Australia that teaches young people in grades 10-12 how to identify and respond to signs of mental health challenges and crises among peers. Recognizing the growing adolescent mental health crisis in the USA, the National Council for Mental Wellbeing, in partnership with a Johns Hopkins University research team, used a multimethod research approach to adapt the program culturally and contextually from Australia to the USA. The goals of the study were to engage adolescents, MHFA instructors, and content area experts (N = 171) in a process to determine: how to retain the elements of the course that were evidence-based and effective while adapting the program for US students, what topics to add so US students have the essential information and skills teens needed to help a friend experiencing a mental health challenge or crisis, what changes to make to curriculum materials to ensure the style and delivery resonate with US students, and what tools to include so the program is implemented safely and with fidelity in diverse US schools. This paper outlines the adaptation process, including engaging participants, identifying key recommendations for modification, and making changes to the tMHFA program. The findings demonstrate the types of adaptations that may be needed to facilitate implementation and maintenance of program effectiveness when introducing tMHFA to new populations of students in the USA. In addition, the process outlined can be replicated toward this purpose as the program continues to expand both in the USA and in other countries.

Polygenic Scores and Onset of Major Mood or Psychotic Disorders Among Offspring of Affected Parents

OBJECTIVE

Family history is an established risk factor for mental illness. The authors sought to investigate whether polygenic scores (PGSs) can complement family history to improve identification of risk for major mood and psychotic disorders.

METHODS

Eight cohorts were combined to create a sample of 1,884 participants ages 2-36 years, including 1,339 offspring of parents with mood or psychotic disorders, who were prospectively assessed with diagnostic interviews over an average of 5.1 years. PGSs were constructed for depression, bipolar disorder, anxiety, attention deficit hyperactivity disorder (ADHD), schizophrenia, neuroticism, subjective well-being, p factor, and height (as a negative control). Cox regression was used to test associations between PGSs, family history of major mental illness, and onsets of major mood and psychotic disorders.

RESULTS

There were 435 onsets of major mood and psychotic disorders across follow-up. PGSs for neuroticism (hazard ratio=1.23, 95% CI=1.12-1.36), schizophrenia (hazard ratio=1.15, 95% CI=1.04-1.26), depression (hazard ratio=1.11, 95% CI=1.01-1.22), ADHD (hazard ratio=1.10, 95% CI=1.00-1.21), subjective well-being (hazard ratio=0.90, 95% CI=0.82-0.99), and p factor (hazard ratio=1.14, 95% CI=1.04-1.26) were associated with onsets. After controlling for family history, neuroticism PGS remained significantly positively associated (hazard ratio=1.19, 95% CI=1.08-1.31) and subjective well-being PGS remained significantly negatively associated (hazard ratio=0.89, 95% CI=0.81-0.98) with onsets.

CONCLUSIONS

Neuroticism and subjective well-being PGSs capture risk of major mood and psychotic disorders that is independent of family history, whereas PGSs for psychiatric illness provide limited predictive power when family history is known. Neuroticism and subjective well-being PGSs may complement family history in the early identification of persons at elevated risk.

Assessment of Selective and Universal Screening for Suicide Risk in a Pediatric Emergency Department

Importance

According to National Patient Safety Goal 15.01.01, all individuals being treated or evaluated for behavioral health conditions as their primary reason for care in hospitals and behavioral health care organizations accredited by The Joint Commission should be screened for suicide risk using a validated tool. Existing suicide risk screens have minimal or no high-quality evidence of association with future suicide-related outcomes.

Objective

To test the association between results of the Ask Suicide-Screening Questions (ASQ) instrument in a pediatric emergency department (ED), implemented through selective and universal screening approaches, and subsequent suicide-related outcomes.

Design Setting and Participants

In this retrospective cohort study at an urban pediatric ED in the United States, the ASQ was administered to youths aged 8 to 18 years with behavioral and psychiatric presenting problems from March 18, 2013, to December 31, 2016 (selective condition), and then to youths aged 10 to 18 years with medical presenting problems (in addition to those aged 8-18 years with behavioral and psychiatric presenting problems) from January 1, 2017, to December 31, 2018 (universal condition).

Exposure

Positive ASQ screen at baseline ED visit.

Main Outcomes and Measures

The main outcomes were subsequent ED visits with suicide-related presenting problems (ie, ideation or attempts) based on electronic health records and death by suicide identified through state medical examiner records. Association with suicide-related outcomes was calculated over the entire study period using survival analyses and at 3-month follow-up for both conditions using relative risk.

Results

The complete sample was 15003 youths (7044 47.0%] male; 10209 [68.0%] black; mean [SD] age, 14.5 [3.1] years at baseline). The follow-up for the selective condition was a mean (SD) of 1133.7 (433.3) days; for the universal condition, it was 366.2 (209.2) days. In the selective condition, there were 275 suicide-related ED visits and 3 deaths by suicide. In the universal condition, there were 118 suicide-related ED visits and no deaths during the follow-up period. Adjusting for demographic characteristics and baseline presenting problem, positive ASQ screens were associated with greater risk of suicide-related outcomes among both the universal sample (hazard ratio, 6.8 [95% CI, 4.2-11.1]) and the selective sample (hazard ratio, 4.8 [95% CI, 3.5-6.5]).

Conclusions and Relevance

Positive results of both selective and universal screening for suicide risk in pediatric EDs appear to be associated with subsequent suicidal behavior. Screening may be a particularly effective way to detect suicide risk among those who did not present with ideation or attempt. Future studies should examine the impact of screening in combination with other policies and procedures aimed at reducing suicide risk.Appeared originally in JAMA Netw Open 2019; 2:e1914070.

Expanding on Threat and Deprivation: Empirical Examination of Adversity Dimensions and Psychiatric Outcomes Among Emerging Adults

Dimensional models of adversity, whereby experiences lie along dimensions of threat and deprivation, are increasingly popular; however, their empirical validation is limited. In a sample of emerging adults (N=1,662; M age =20.72; 53% female; 72% Black), we conducted exploratory factor analyses using adversities derived from items probing family relationships and a validated assessment of traumatic events. Resulting factors were used to test associations with odds of lifetime diagnosis of a substance use disorder, other mental health disorders, and suicide attempt. Results supported a four-factor solution: threat (non-betrayal), emotional deprivation, sexual assault, and threat (betrayal). Threat (betrayal) summary scores were most strongly associated with increased odds of substance use and other disorders, whereas sexual assault was most strongly associated increased odds of lifetime suicide attempt. Findings provide some empirical support for categorizing adversity along dimensions of threat and deprivation. However, it also suggests the possibility of further divisions within these dimensions.

Racial Differences in Emergency Department Visit Characteristics and Management of Preadolescents at Risk of Suicide

OBJECTIVE

Suicide rates and frequency of pediatric emergency department (ED) visits for suicidal thoughts and behaviors have increased among Black preadolescents in the United States in recent years. This study examined whether characteristics of ED visits and treatment management of preadolescents with suicidal thoughts and behaviors differed by race.

METHODS

An electronic medical record query identified patients ages 8-12 (N=504) who visited a pediatric ED with a psychiatric-related chief complaint in 2019. The authors examined suicidal thoughts and behaviors that were reported with the Ask Suicide-Screening Questions tool, ED clinical impression, and ED disposition overall and by race.

RESULTS

Compared with other racial groups, Black preadolescents were less likely to report suicidal thoughts, despite equivalent lifetime histories of suicide attempts, and were more likely to be brought to the ED by police and discharged (instead of being admitted to inpatient psychiatric care).

CONCLUSIONS

Research to better understand racial disparities in suicide risk among preadolescents can inform prevention efforts.

Posttraumatic stress disorder and risk of suicidal behavior: A systematic review and meta-analysis

INTRODUCTION

This study conducted a systematic review and meta-analysis of the association between posttraumatic stress disorder (PTSD) and (i) death by suicide, (ii) attempted suicide (AS), and (iii) suicidal ideation (SI).

METHODS

The systematic review identified seven studies on PTSD and suicide, 33 studies for AS, and 20 studies for SI. A series of stratified meta-analyses were conducted to estimate pooled effects, in addition to meta-regression to investigate sources of heterogeneity.

RESULTS

A higher relative risk of suicide was evident among those diagnosed with PTSD (RR = 2.09 [95% confidence interval (CI): 1.11-3.94]), with strongest associations among combat veterans (RR = 3.97, 95% CI 2.22-7.10). A lower relative risk of suicide among those with PTSD and co-morbid psychiatric conditions was evident (RR = 0.74, 95% CI 0.63-0.86). A strong association between PTSD and attempted suicide (RR = 4.05, 95% CI 3.14-5.23) and suicidal ideation (RR = 2.91, 95% CI 2.22-3.82) was also found, with a consistently strong association among those with co-morbid psychiatric conditions and non-clinical cohorts.

CONCLUSION

This review found a strong association between PTSD and death by suicide, attempted suicide, and suicidal ideation, and also suicide among veteran populations. Early identification and treatment of PTSD across both clinical and non-clinical cohorts should be a priority for suicide prevention.

A Brief Text-Messaging Intervention for Suicidal Youths After Emergency Department Discharge

Research has shown that the months after hospital discharge following treatment for suicidal thoughts or behaviors is a high-risk period for suicide. Moreover, the needs of a subset of youths at increased risk for suicide are not being met by community mental health providers, resulting in frequent emergency department (ED) visits. While undertaking a quality improvement effort, the authors' health care system piloted caring text messages to support youths discharged from the hospital after screening positive for suicide risk in the ED. The text-messaging intervention was feasible and acceptable, and youths reported that the messages helped reduce their suicidal thoughts and behaviors postdischarge. The results of this text-messaging intervention prompted the Maryland Department of Health to offer a similar intervention to all Marylanders.

Achieving health equity in US suicides: a narrative review and commentary

Suicide rates in the United States (US) reached a peak in 2018 and declined in 2019 and 2020, with substantial and often growing disparities by age, sex, race/ethnicity, geography, veteran status, sexual minority status, socioeconomic status, and method employed (means disparity). In this narrative review and commentary, we highlight these many disparities in US suicide deaths, then examine the possible causes and potential solutions, with the overarching goal of reducing suicide death disparities to achieve health equity.

The data implicate untreated, undertreated, or unidentified depression or other mental illness, and access to firearms, as two modifiable risk factors for suicide across all groups. The data also reveal firearm suicides increasing sharply and linearly with increasing county rurality, while suicide rates by falls (e.g., from tall structures) decrease linearly by increasing rurality, and suicide rates by other means remain fairly constant regardless of relative county urbanization. In addition, for all geographies, gun suicides are significantly higher in males than females, and highest in ages 51–85 + years old for both sexes. Of all US suicides from 1999–2019, 55% of male suicides and 29% of female suicides were by gun in metropolitan (metro) areas, versus 65% (Male) and 42% (Female) suicides by gun in non-metro areas. Guns accounted for 89% of suicides in non-metro males aged 71–85 + years old. Guns (i.e., employment of more lethal means) are also thought to be a major reason why males have, on average, 2–4 times higher suicide rates than women, despite having only 1/4—1/2 as many suicide attempts as women. Overall the literature and data strongly implicate firearm access as a risk factor for suicide across all populations, and even more so for male, rural, and older populations.

To achieve the most significant results in suicide prevention across all groups, we need 1) more emphasis on policies and universal programs to reduce suicidal behaviors, and 2) enhanced population-based strategies for ameliorating the two most prominent modifiable targets for suicide prevention: depression and firearms.

Anxiety symptoms and suicidal thoughts and behaviors among patients with mood disorders

BACKGROUND

Though the association between anxiety disorders and suicidal behavior is well-described, the impact of anxiety symptoms on suicidal thoughts and behaviors (STB) across different mood disorders is still unclear.

METHODS

We performed a registry-based retrospective study utilizing outcome measure data collected by the National Network of Depression Centers (NNDC), a nationwide nonprofit consortium of 26 leading clinical and academic member centers in the United States. The sample consisted of 2607 outpatients with mood disorders (major depressive disorder or bipolar disorders). Demographic and clinical variables were compared based on the presence or absence of STB and severity of anxiety symptoms (minimal, mild, moderate, and severe). Univariate and multivariable logistic regressions were conducted to examine the correlations of STB, considering multicollinearity.

RESULTS

Patients with mild, moderate, and severe anxiety symptoms had higher odds of STB than those with minimal symptoms. Gender, marital status, age, and depressive symptoms were other strong predictors of STB. There was no difference in the odds of STB between patients with major depressive disorder (MDD) and those with bipolar disorders (BD). However, the odds of suicidal ideation were slightly lower among patients with BD than those with MDD.

LIMITATIONS

Our sample was comprised only of outpatients, limiting the generalization of our findings. Other limitations include the lack of structured interviews for diagnostic characterization of the patients and the utilization of data on anxiety and mood obtained solely through self-report scales.

CONCLUSIONS

We found a cross-sectional association between the severity of anxiety symptoms and STB among patients with mood disorders. This study demonstrates the need for a suicide risk assessment in patients with mood disorders reporting anxiety symptoms.

A suicide prevention initiative across a multi-campus university before and during the COVID-19 pandemic

Increasing rates of depression, anxiety, substance use, and suicidal thoughts and behaviors among college students were exacerbated by the COVID-19 pandemic. This report describes how components of the Johns Hopkins Suicide Prevention Awareness, Response and Coordination (JH-SPARC) Project aligned with a multi-faceted strategy for suicide prevention. Key programs included suicide screening, gatekeeper trainings, and the use of third-party mental health services. Regarding suicide screening outcomes, staff sent 36,148 individual emails inviting students and trainees to participate in stress and depression screening. This approach garnered 2,634 responses and connected 130 students to care, 66 of whom (50.8%) indicated suicidal thoughts, plans, or behaviors. We estimate this screening cost $2.97 per student. Important lessons included the reliance on virtual platforms and the need to coordinate efforts across multiple campuses. Our manuscript provides an example of a transferable strategy for suicide prevention on college campuses in the pandemic era.

Utilizing Moderated Non-linear Factor Analysis Models for Integrative Data Analysis: A Tutorial

Integrative data analysis (IDA) is an analytic tool that allows researchers to combine raw data across multiple, independent studies, providing improved measurement of latent constructs as compared to single study analysis or meta-analyses. This is often achieved through implementation of moderated nonlinear factor analysis (MNLFA), an advanced modeling approach that allows for covariate moderation of item and factor parameters. The current paper provides an overview of this modeling technique, highlighting distinct advantages most apt for IDA. We further illustrate the complex modeling building process involved in MNLFA by providing a tutorial using empirical data from five separate prevention trials. The code and data used for analyses are also provided.

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 Risk Screening in Pediatric Outpatient Neurodevelopmental Disabilities Clinics

OBJECTIVE

The purpose of this study was to describe the implementation of universal suicide risk screening in pediatric neurodevelopmental disabilities (NDD) medical clinics, analyze demographic and clinical characteristics of eligible patients, describe outcomes of positive screenings, and describe factors that influenced participation in screenings.

METHODS

A suicide risk screening protocol was developed and implemented for medical clinic patients aged 8 to 18 years. Registered nurses screened patients using the "Ask Suicide-Screening Questions" tool during triage. Positive screenings were referred for further assessment and mental health management. Demographics and clinical data were extracted from medical records using retrospective chart reviews.

RESULTS

During the 6-month study period, 2961 individual patients presented for 5260 screening eligible patient visits. In total, 3854 (73.3%) screenings were completed with 261 (6.8%) positive screenings noted. Screenings were declined in 1406 (26.7%) visits. Parents of children with cognitive impairments were more likely to decline screening. Clinics serving children with autism spectrum disorder had higher rates of positive screenings compared with all other clinic attendees. Seventy-two of 187 children (38.5%) with positive screenings were identified and referred to outpatient mental health referrals. Seven (2.5%) of these children required acute psychiatric treatment.

CONCLUSION

Routine screening, identification of increased suicide risk, and referral to mental health care among children with NDD are feasible. It remains unclear whether variation in rates among youth with and without NDD may indicate true differences in suicide risk or cognitive impairments or reflect psychiatric comorbidities. High rates of declined participation may have influenced identification of children with NDD and suicide risk. Preliminary findings identified groups of children with NDD at heightened risk for suicidal ideation and behavior. Further research is needed to assess the validity of suicide risk screening tools in children with neurodevelopmental disorders.

Marijuana Use Is Associated With Suicidal Ideation and Behavior Among US Adolescents at Rates Similar to Tobacco and Alcohol

This study used data from the National Youth Risk Behavior Survey to examine the association between adolescent marijuana, tobacco, and alcohol use and suicidal ideation and attempts over a period of six years (2011-2017), as attitudes and laws became more permissive of marijuana use. We used logistic regression to control for possible confounders, estimate marginal prevalence ratios (PR's), and assess changes over time. Marijuana was more strongly associated with suicide attempts than ideation, and more frequent use was associated with significantly greater risk. The effect has not changed substantively since 2011, despite changing attitudes toward marijuana. Marijuana is broadly comparable to other substances: results for tobacco were similar, though frequent alcohol use had a significantly stronger association than other substances.

Testing the Impact of the Whole-Day Good Behavior Game on Aggressive Behavior: Results of a Classroom-Based Randomized Effectiveness Trial

Three generations of developmental epidemiologically based randomized field trials of the Good Behavior Game (GBG) have been delivered to Baltimore elementary schools. With the collaboration of family and community partners, all three trials were directed at decreasing proximal targets of aggressive behavior and improving learning in first-grade classrooms with distal mental health and substance abuse outcomes. GBG is a group-contingent classroom behavior management strategy that promotes classmate/peer concern for each child's positive behavior by rewarding teams with below-criterion levels of aggressive, disruptive behavior. GBG targets early risk factors for the above distal outcomes: aggressive, disruptive behavior, family/school relationships, and school failure. Here, we report on the third-generation randomized prevention trial of the GBG (whole-day first grade program (WD)), including 12 elementary schools. WD enhanced the standard curriculum in the areas of classroom behavior management; academic instruction, particularly reading; and family-classroom partnerships. Using a within-school classroom randomized trial design, we: 1) evaluate the effectiveness of the WD program by sex and cohort and 2) measure variation in WD impact by the quality of teachers' behavior management practices. Data from 961 first graders were used in general growth mixture modeling that accounts for classroom randomization to identify distinct developmental trajectories of aggressive, disruptive behavior and GBG impact on these trajectories. In the chronic high aggression trajectory of males, ratings of aggression after WD implementation and to the end of third grade were significantly lower in the WD condition than in controls in classrooms with a higher WD dosage (Cohort 2) and especially in classrooms with higher quality of WD implementation. For females, we found a modest but significant benefit of GBG in the low trajectory class when cohorts were combined. Regarding policy implications, embedding GBG into the curricula in teacher's colleges could better support student learning and behavior. Clinical Trials Registration number: NCT00257088.

Ineligibility for and Refusal to Participate in Randomized Controlled Trials That Have Studied Impact on Suicide-Related Outcomes in the United States: A Meta-Analysis

Objective: Ineligibility for and refusal to participate in randomized controlled trials (RCTs) can potentially lead to unrepresentative study samples and limited generalizability of findings. We examined the rates of exclusion and refusal in RCTs that have studied impact on suicide-related outcomes in the US. Data Sources: PubMed, the Cochrane Library, the Campbell Collaboration Library of Systematic Reviews, CINAHL, PsycINFO, and Education Resources Information Center were searched from January 1990 to May 2020 using the terms (suicide prevention) AND (clinical trial). Study Selection: Of 8,403 studies retrieved, 36 RCTs assessing effectiveness on suicide-related outcomes in youth (≤ 25 years old) conducted in the US were included. Data Extraction: Study-level data were extracted by 2 independent investigators for a random-effects meta-analysis and meta-regression. Results: The study participants (N = 13,264) had a mean (SD) age of 14.87 (1.58) years and were 50% male, 23% African American, and 24% Hispanic. The exclusion rate was 36.4%, while the refusal rate was 25.5%. The exclusion rate was significantly higher in the studies excluding individuals not exceeding specified cutoff points of suicide screening tools (51.2%; adjusted linear coefficient [β] = 1.30, standard error [SE] = 0.15; P = .041) and individuals not meeting the age or school grade criterion (45.9%; β = 1.37, SE = 0.13; P = .005). Conclusions: The rates of exclusion and refusal in youth prevention interventions studying impact on suicide-related outcomes were not as high compared to the rates found in other mental and behavioral interventions. While there was strong racial/ethnic group representation in RCTs examining youth suicide-related outcomes, suicide severity and age limited eligibility.

Comparing the predictive value of screening to the use of electronic health record data for detecting future suicidal thoughts and behavior in an urban pediatric emergency department: A preliminary analysis

AIM

Brief screening and predictive modeling have garnered attention for utility at identifying individuals at risk of suicide. Although previous research has investigated these methods, little is known about how these methods compare against each other or work in combination in the pediatric population.

METHODS

Patients were aged 8-18 years old who presented from January 1, 2017, to June 30, 2019, to a Pediatric Emergency Department (PED). All patients were screened with the Ask Suicide Questionnaire (ASQ) as part of a universal screening approach. For all models, we used 5-fold cross-validation. We compared four models: Model 1 only included the ASQ; Model 2 included the ASQ and EHR data gathered at the time of ED visit (EHR data); Model 3 only included EHR data; and Model 4 included EHR data and a single item from the ASQ that asked about a lifetime history of suicide attempt. The main outcome was subsequent PED visit with suicide-related presenting problem within a 3-month follow-up period.

RESULTS

Of the N = 13,420 individuals, n = 141 had a subsequent suicide-related PED visit. Approximately 63% identified as Black. Results showed that a model based only on EHR data (Model 3) had an area under the curve (AUC) of 0.775 compared to the ASQ alone (Model 1), which had an AUC of 0.754. Combining screening and EHR data (Model 4) resulted in a 17.4% (absolute difference = 3.6%) improvement in sensitivity and 13.4% increase in AUC (absolute difference = 6.6%) compared to screening alone (Model 1).

CONCLUSION

Our findings show that predictive modeling based on EHR data is helpful either in the absence or as an addition to brief suicide screening. This is the first study to compare brief suicide screening to EHR-based predictive modeling and adds to our understanding of how best to identify youth at risk of suicidal thoughts and behaviors in clinical care settings.

Effects of polygenic risk for suicide attempt and risky behavior on brain structure in young people with familial risk of bipolar disorder

Bipolar disorder (BD) is associated with a 20-30-fold increased suicide risk compared to the general population. First-degree relatives of BD patients show inflated rates of psychopathology including suicidal behaviors. As reliable biomarkers of suicide attempts (SA) are lacking, we examined associations between suicide-related polygenic risk scores (PRSs)-a quantitative index of genomic risk-and variability in brain structures implicated in SA. Participants (n = 206; aged 12-30 years) were unrelated individuals of European ancestry and comprised three groups: 41 BD cases, 96 BD relatives ("high risk"), and 69 controls. Genotyping employed PsychArray, followed by imputation. Three PRSs were computed using genome-wide association data for SA in BD (SA-in-BD), SA in major depressive disorder (SA-in-MDD) (Mullins et al., 2019, The American Journal of Psychiatry, 176(8), 651-660), and risky behavior (Karlsson Linnér et al., 2019, Nature Genetics, 51(2), 245-257). Structural magnetic resonance imaging processing employed FreeSurfer v5.3.0. General linear models were constructed using 32 regions-of-interest identified from suicide neuroimaging literature, with false-discovery-rate correction. SA-in-MDD and SA-in-BD PRSs negatively predicted parahippocampal thickness, with the latter association modified by group membership. SA-in-BD and Risky Behavior PRSs inversely predicted rostral and caudal anterior cingulate structure, respectively, with the latter effect driven by the "high risk" group. SA-in-MDD and SA-in-BD PRSs positively predicted cuneus structure, irrespective of group. This study demonstrated associations between PRSs for suicide-related phenotypes and structural variability in brain regions implicated in SA. Future exploration of extended PRSs, in conjunction with a range of biological, phenotypic, environmental, and experiential data in high risk populations, may inform predictive models for suicidal behaviors.

Prospective examination of self-harm up to three years after contact with Child Protective Services (CPS)

We examined the prevalence and correlates of self-harm among adolescents in the three years following an investigation by U.S. Child Protective Services (CPS) into alleged child maltreatment. Participants (N = 1573, 47% Male, 45% White) were drawn from the National Survey of Child and Adolescent Well-Being, cohort II. Self-harm was assessed at the conclusion of the CPS investigation, and at 18- and 36-months follow-up. Descriptive statistics and multivariable logistic regression were used to assess differences in self-harm over time by demographic characteristics, maltreatment type, and out-of-home placement. The prevalence of self-harm among older adolescents (15-17 years) remained stable at ∼10%, while among younger adolescents (11-14 years), it declined from 13% to 3.5%. Approximately 4.5% of youth reported self-harm at multiple survey waves. Native American and Asian/Pacific Islander youth were five times more likely to report repeated self-harm. Further research is warranted to understand this heightened risk.

Psychometric properties of the 7-item version of the Concise Health Risk Tracking Self-Report Scale for rural adults enrolled in an Internet-delivered self-help program for depression

PURPOSE

Monitoring suicide risk in clinical practice requires valid and reliable assessment instruments. This study evaluated the psychometric properties of the 7-item version of the Concise Health Risk Tracking Self-Report, CHRT-SR₇ in a primarily rural population.

METHODS

The sample comprised 788 participants (81.7% female) of an effectiveness trial of an internet-based self-help intervention for depression. Participants completed self-report questionnaires, including the CHRT-SR₇ , Patient Health Questionnaire-9, Generalized Anxiety Disorder-7, Work and Social Adjustment Scale, Connor-Davidson Resilience Scale-10, and Barriers to Seeking Mental Health Care. Four-week test-retest reliability was calculated for a subsample of 147 participants randomized to a waitlist control group.

FINDINGS

The CHRT-SR₇ internal consistency was α = 0.80 (total sample), α = 0.80 (women), and α = 0.83 (men). The 4-week test-retest reliability was strong for women (r = 0.78) and moderate for men (r = 0.66). Confirmatory factor analysis supported the original 3-factor solution: Hopelessness (2 items), Perceived Lack of Social Support (2 items), and Current Suicidal Thoughts and Plans (3 items), which was invariant across gender and rural status. Convergent and divergent validity was supported as reflected in significant correlations of the CHRT-SR₇ and its subscales with measures of depression, anxiety, adjustment, and resilience. Limitations include the limited demographic diversity (mostly non-Hispanic White women) and reliance on self-report data.

CONCLUSIONS

Our findings complement those reported in prior studies of patients with severe depression and support the use of the CHRT-SR₇ for measuring suicide risk in rural adults; future studies should further test the instrument's psychometric properties in racial or ethnic minority rural residents.

Lowering the Age Limit in Suicide Risk Screening: Clinical Differences and Screening Form Predictive Ability

Our research provides preliminary evidence that suicide risk screening is warranted in patients as young as 8-9 years old presenting to the emergency department (ED) with behavioral and mental health symptoms. The goal of this retrospective cohort study (N = 2,466 unique patient visits) was to assess the value of suicide risk screening in children younger than 10 years old who present to the ED with behavioral and mental health concerns. The Johns Hopkins Hospital pediatric ED began screening with the Ask Suicide-Screening Questions (ASQ) for patients 8-21 years old who presented with a behavioral or mental health concern in March 2013 as ED standard of care. We examined the demographic and clinical differences between younger (8-9 years old; n = 270) and older (10-21 years old; n = 2,196) youths who were screened for suicide risk with the ASQ (from March 13, 2013 through December 31, 2016). In summary, 36% of 8- and 9-year-old patients who came to the ED for behavioral and mental health concerns screened positive for suicide risk on the ASQ. The younger patients who screened positive were more likely to present with externalizing symptoms and hallucinations and less likely to present with suicidal ideation or an attempt than their older counterparts. Importantly, 71.1% of 8- to 9-year-old patients who screened positive did not present to the ED for suicidal ideation or attempt vs 50.1% (614/1,226) of patients older than age 10 years.

Serum Fatty Acid Latent Classes Are Associated With Suicide in a Large Military Personnel Sample

OBJECTIVE

Fatty acids (FAs) are involved in the functioning of biological systems previously associated with suicidal behavior (eg, monoamine signaling and the immune system). We sought to determine (1) whether observed FA levels in a sample of military suicide decedents and living matched controls were consistent with latent classes having distinctive FA profiles and (2) whether those latent classes were associated with suicide and mental health diagnoses.

METHODS

Serum samples from 800 US military suicide decedents who died between 2002 and 2008 and 800 demographically matched living controls were selected at random from a large military serum repository and assayed for 22 different FAs. A latent class cluster analysis was performed using values of 6 FAs previously individually associated with suicide. Once the latent classes were identified, they were compared in terms of suicide decedent proportion, demographic variables, estimated FA enzyme activity, diagnoses, and mental health care usage.

RESULTS

A 6-latent class solution best characterized the dataset. Suicide decedents were less likely to belong to 2 of the classes and more likely to belong to 3 of the classes. The low-decedent classes differed from the high-decedent classes on 9 FAs and on estimated indices of activity for 3 FA enzymes: 14:0, 24:0, 18:1 n-9, 24:1 n-9, 22:5 n-3, 22:6 n-3, 20:2 n-6, 20:4 n-6, 22:5 n-6, elongation of very long chain fatty acids protein 1 (ELOVL1), ELOVL6, and Δ9 desaturase. The FA profiles of the latent classes were consistent with biological abnormalities previously associated with suicidal behavior.

CONCLUSIONS

This study suggests the utility of methods that simultaneously examine multiple FAs when trying to understand their relationship with suicide and psychiatric illness.

Nonsuicidal self-injury, suicidal ideation, and suicide attempt among collegiate athletes: Findings from the National College Health Assessment

To evaluate whether collegiate athletes and nonathlete college students differ in nonsuicidal self-injury (NSSI), suicidal ideation, suicide attempt, and help-seeking behaviors. Participants: 165,210 respondents to the American College Health Association's National College Health Assessment (NCHA), a survey administered to college students by participating institutions during Fall 2011 to Spring 2015. Methods: Single-level binary logistic regression with equality of coefficients tests and chi-square analyses. Results: The models for NSSI and suicide attempt differed slightly between student-athletes and nonathletes. Most notably, stress is a stronger correlate of NSSI (Z = 3.03, p < .01) for nonathletes while difficulties with social relationships is a stronger correlate of suicide attempt for student-athletes (Z=-3.13, p < .01). Conclusion: Our findings highlight the salience of relationship problems as a correlate with suicide attempts in student-athletes. Difficulty in romantic or other social relationships could be a marker of risk or an identifiable, actionable target for preventing future suicidal behaviors among collegiate athletes.

Parental bipolar disorder, family environment, and offspring psychiatric disorders: A systematic review

BACKGROUND

Our objective was to systematically review non-experimental studies of parental bipolar disorder (BD), current family environment, and offspring psychiatric disorders to identify characteristics of family environment associated with parental BD and risk for offspring psychiatric disorders.

METHODS

CINAHL, Embase, PsycINFO, and PubMed were searched using MeSH terms to identify studies on offspring of BD parents published through September 2017. We followed PRISMA guidelines and used the Risk of Bias Assessment Tool for Nonrandomized Studies (RoBANS). We calculated prevalence ratios and 95% confidence intervals to compare offspring psychiatric disorders within and across studies.

RESULTS

Of 10,454 unique documents retrieved, we included 13 studies. The most consistent finding was lower parent-reported cohesion in families with a BD parent versus no parental psychiatric disorders. Family environment did not differ between BD parents and parents with other disorders. Offspring of BD parents had higher prevalence of psychiatric disorders than offspring of parents without psychiatric disorders but did not differ from offspring of parents with other disorders. Families with a BD child had higher conflict than families without a BD child.

LIMITATIONS

Comparisons between studies were qualitative. A single reviewer conducted screening, data extraction, and bias assessment.

CONCLUSIONS

Family environment in families with a BD parent is heterogeneous. The pattern of findings across studies also suggests that family problems may be associated with parental psychiatric illness generally rather than parental BD in particular. Few studies included offspring-reported measures. Given the association of family conflict with offspring mood disorders, further study is merited on children's perceptions of the family environment in the BD high-risk context.

Co-occurring risk factors among U.S. high school students at risk for suicidal thoughts and behaviors

BACKGROUND

Suicidal thoughts and behaviors (STBs) are increasing among adolescents in the United States and are challenging to predict and prevent.  The current study identifies subtypes of youth at risk for suicidal thoughts and behaviors (STBs) in school-based settings.

METHOD

Data are from the CDC's 2015 and 2017 National Youth Risk Behavior Survey of US high school students. Among students reporting depression symptoms, latent class analysis is used to identify subtypes at risk for STBs based on personal characteristics, risk behaviors and environments.

RESULTS

Two distinct subtypes of youth were found to be at high risk for STBs: The first, larger subtype (22%) is predominately females in early high school, many of whom identify as bisexual, experienced past-year bullying, and are likely to have experienced sexual victimization.  These students have low levels of externalizing risk behaviors making them difficult to detect.  The second high-risk subtype (7%) is characterized by students with significant social integration challenges, with extremely high levels of substance abuse, fighting, physical and sexual victimization and poor academic performance.  Many of these students have low English fluency, and identify as sexual minority.

LIMITATIONS

Due to attrition or language barriers, experiences of some students at high-risk for STBs may not have been captured by this survey.

CONCLUSION

Universal screening in clinical settings, and universally focused suicide prevention programs in school-based settings are needed and should be introduced early on. Interventions should be tailored to reach high-risk students with language, cultural and social integration challenges.

Screening for Suicide Risk Among Youths With a Psychotic Disorder in a Pediatric Emergency Department

National Patient Safety Goal 15.01.01 requires all Joint Commission-accredited organizations to screen patients treated for behavioral health conditions for suicide risk. However, little is known about the ability of screening tools to identify suicide risk among youths with psychotic disorders. As part of this quality improvement initiative, youths in a pediatric emergency department with psychotic disorder diagnoses (N=87) were screened with the Ask Suicide-Screening Questions. Almost half (48%, N=42) screened positive. Most positive screens (62%, N=26) were not detected through treatment as usual, suggesting that systematic screening improves the detection of suicide risk among youths with psychotic disorders.

Global risks of suicidal behaviours and being bullied and their association in adolescents: School-based health survey in 83 countries

BACKGROUND

Global risks of suicidal behaviours (SB) and being bullied as well as their association among adolescents have been poorly understood. We aimed to determine the risks of suicidal ideation (SI), suicide planning (SP), suicide attempt (SA) and being bullied in adolescents and their related associations across gender, countries and different WHO regions.

METHODS

We examined data from the Global School-based Health Survey (GSHS), which recorded health behaviours among adolescents aged 12 to 15 years from 83 countries. We computed prevalence rates of SB and being bullied and their 95% confidence intervals (CIs). Multilevel models were employed to examine the association of being bullied with risks of SI, SP and SA.

RESULTS

The overall prevalence of SI was 16·5%, SP 16·5%, SA 16·4%, and being bullied 35·3%. The highest risks of SB and being bullied were in Africa (SI 19·9%, SP 23·2%, SA 20·8%, being bullied 48·0%). Compared to boys, girls had an increased risk for SI (18·2%) and SP (17·3%) but similar risk for SA (16·7%) and being bullied (33·3%). Being bullied was associated with SA (adjusted odds ratio ‒ aOR 2·14, 95%CI 2·06-2·23), more strongly than SI (1·83, 1·78-1·89) and SP (1·70, 1·65-1·76). The strongest association with SA was in the Western Pacific (2·68, 2·45-2·92) and with SI (2·04, 1·74-2·39) and SP (1·81, 1·68-1·95) were in Southeast Asia. There were no gender differences in aOR for SI and SP, but the aOR for SA among boys (2·28, 2·14-2·42) was significantly greater than among girls (2·04, 1·93-2·15), ratio of two odds ratios was 1.12 (P = 0.008).

INTERPRETATION

SB and being bullied were common among adolescents worldwide. The findings of gender differences in SB, being bullied and their association could inform the design of prevention programmes to reduce the risks of SI, SP and SA in adolescents worldwide.

Psychotic experiences and suicidal outcomes in a general population sample

Psychotic experiences (PEs) are associated with suicidal ideation and attempts. However, studies examining the role of potential psychosocial confounders in these associations have yielded variable and inconclusive results. In the current study, data from 974 participants in a general population sample were analyzed. We fitted four regression models to examine the associations between PEs vs. suicidal ideation and attempts, using hierarchical adjustments for sociodemographic factors and psychosocial risk factors. After adjustment for sociodemographic factors and psychosocial factors, PEs were associated with increased odds of suicidal ideation (odds ratio (OR) = 1.89, 95% CI = 1.12-3.22) and suicide attempts (OR = 4.33, 95% CI = 1.77-10.60). For both suicidal ideation and attempts, the association was attenuated but remained statistically significant, even at the highest level of adjustment. Sociodemographic factors and psychosocial factors substantially confound the association between PEs and suicidal ideation and attempts. When adjusting for these confounders, PEs remain independently associated with both suicidal ideation and attempts.
