Accounting for Diversity in Suicide Research: Sampling and Sample Reporting Practices in the United States

Immigration Status, Legal Vulnerability, and Suicidal/Self-harm Ideation Disparities Among Immigrant-Origin Latinx Young Adults in the U.S

Theories of suicidality typically center intrapersonal processes, with limited attention to social determinants of mental health disparities. Using a legal vulnerability framework, we examined the association between self/parental immigration status and suicidal and self-harm ideation (SI) disparities in three groups of immigrant-origin Latinx young adults attending college in the USA: undocumented students (n = 564), US citizens with undocumented parents (n = 605), and US citizens with lawfully present parents (n = 596). We also evaluated whether self/parental immigration status differences in SI could be accounted for by six dimensions of legal vulnerability and, based on prominent theories of suicidality, explored the role of campus belongingness as a protective factor. Participants completed self-report measures, and SI was assessed using one item from the Patient Health Questionnaire-9, a screening tool that assesses the severity of depression symptomatology. Rates of SI were significantly higher among undocumented students (23.1%) and US citizens with undocumented parents (24.3%) compared to US citizens with lawfully present parents (17.8%). Immigration policy-related social exclusion and discrimination-mediated self/parental immigration status differences in SI. Although food insecurity did not differ by self/parental immigration status, greater food insecurity was associated with higher likelihood of SI. Greater campus belongingness was associated with a lower likelihood of endorsing SI for all students regardless of immigration status or legal vulnerability factors. Findings underscore the importance of examining self and parental immigration status as a social determinant of SI and the value of investigating aspects of legal vulnerability as explanatory factors.

Measures of Suicidal Thoughts and Behaviors in Children and Adolescents: A Systematic Review and Recommendations for Use in Clinical and Research Settings

Empirically supported measures of suicidal thoughts and behaviors (STBs) are needed to serve as reference outcomes for suicide risk screening tools and to monitor severity and treatment progress in children and adolescents with STBs. The present paper systematically reviewed existing measures of STBs in youth and studies evaluating their psychometric properties and clinical utility. Measures were then evaluated on reliability, validity, and clinical utility. Sixteen articles (20 independent samples) were found with psychometric data with youth samples for eight measures. Interview-based measures were found to have the strongest psychometric support and clinical utility. Significant limitations exist for all self-report measures due to inherent characteristics of these measures that cannot be remedied through additional psychometric study. There is an urgent need for the development and validation of new self-report measures of STBs, particularly for preadolescent children, sexual and gender minority youth, and racial/ethnic minority youth.

A Scoping Review of Suicide Prevention Interventions for Lesbian, Gay, Bisexual, Transgender, Queer, and Other Sexual and Gender Minority Individuals

Purpose: This scoping review summarizes the literature on suicide-specific psychological interventions among lesbian, gay, bisexual, transgender, queer, and other sexual and gender minority (LGBTQ+) people to synthesize existing findings and support future intervention research and dissemination. Methods: Electronic databases PsycInfo and PubMed were searched for reports of psychological intervention studies with suicide-related outcome data among LGBTQ+ people. A total of 1269 articles were screened, and 19 studies met inclusion criteria (k = 3 examined suicide-specific interventions tailored to LGBTQ+ people, k = 4 examined nontailored suicide-specific interventions, k = 11 examined minority stress- or LGBTQ+ interventions that were not suicide-specific, and k = 1 examined other types of interventions). Results: Synthesis of this literature was made challenging by varied study designs, and features limit confidence in the degree of internal and external validity of the interventions evaluated. The only established suicide-specific intervention examined was Dialectical Behavior Therapy, and minority stress- and LGBTQ-specific interventions rarely targeted suicidal thoughts and behaviors (STBs). Nevertheless, most interventions reviewed demonstrated support for feasibility and/or acceptability. Only five studies tested suicide-related outcome differences between an LGBTQ+ group and a cisgender/heterosexual group. These studies did not find significant differences in STBs, but certain subgroups such as bisexual individuals may exhibit specific treatment disparities. Conclusion: Given the dearth of research, more research examining interventions that may reduce STBs among LGBTQ+ people is critically needed to address this public health issue.

Factor Structure and Measurement Invariance of the Suicide Status Form-IV

The Suicide Status Form-IV (SSF-IV) is the measure used in the Collaborative Assessment and Management of Suicidality (CAMS). The SSF-IV Core Assessment measures various domains of suicide risk. Previous studies established a two-factor solution in small, homogeneous samples; no investigations have assessed measurement invariance. The current investigation sought to replicate previous factor analyses and used measurement invariance to identify differences in the Core Assessment by race and gender. Adults (N = 731) were referred for a CAMS consultation after exhibiting risk for suicide. Confirmatory factor analyses indicated good fit for both one- and two-factor solutions while the two-factor solution is potentially redundant. Configural, metric, and scalar invariance held across race and gender. Ordinal logistic regression models indicated that neither race nor gender significantly moderated the relationship between the Core Assessment total score and clinical outcomes. Findings support a measurement invariant, one-factor solution for the SSF-IV Core Assessment.

Accounting for diversity in the treatment of suicide and self-injury: A systematic review of the past 50 years of randomized controlled trials

PURPOSE

Patients receiving treatment for self-injurious thoughts and behaviors (SITBs) have diverse backgrounds, yet it remains unclear exactly who is represented in the current SITB treatment literature.

METHODS

We conducted a systematic review of the past 50 years of randomized controlled trials (RCTs) testing SITB treatments to evaluate sampling practices and reporting of sample characteristics, as well as inclusion of global populations across the included 525 papers. We also assessed changes over the past five decades in these three domains.

RESULTS

SITB RCTs frequently reported age and sex (98.6%-95.1%), less frequently reported race (83.4%-38.6%), socioeconomic status (48.1%-46.1%) and ethnicity (41.9%-8.1%), and rarely reported LGBTQ+ status (3.7%-1.6%). U.S.-based RCTs featured predominantly White, non-Hispanic, and non-LGBTQ+ samples. Most RCTs were conducted in high-income North American or European countries. Sample reporting practices, sample representativeness, and inclusion of global populations modestly and inconsistently improved over time.

CONCLUSIONS

There has not been substantial improvement in reporting practices, sample representativeness, or inclusion of global populations in SITB RCTs over the past 50 years. Acknowledging who is being studied and representing diverse populations in SITB treatment research is key to connecting research advances with those who may need it most.

Informing Equitable Prevention Practices: A Statewide Disaggregated Analysis of Suicide for Ethnoracially Minoritized Adolescents

The increase in adolescent suicide rates in the United States is a pervasive public health issue, and ethnoracial youth with diverse identities are disproportionately impacted, yet less studied. National planning efforts reinforce state-level approaches to suicide prevention through an equitable lens to prevent adolescent suicide. This study examined disaggregated state-level data over time to determine changes to suicide outcomes based on race/ethnicity, sex, sexual orientation, and the intersection of these identities and determined which sub-groups had higher odds of suicide outcomes. Data from the 1991-2019 Centers for Disease Control and Prevention Youth Risk Behavioral Surveillance System were analyzed for 17,419 ethnoracially minoritized high school adolescents in North Carolina. Descriptive analyses and multinominal logistic regression models were employed. Findings indicated that subgroups within categories of ethnoracial populations, specifically Black female adolescents unsure of their sexual orientation, reported higher rates of suicide attempts. Additionally, Multiracial adolescents reported higher means for suicide consideration and attempts over time. Recommendations for investigating state-level suicide data by focusing on diverse intersecting identities to illuminate areas for potential prevention efforts and support health equity are provided.

Reevaluating the "deaths of despair" narrative: Racial/ethnic heterogeneity in the trend of psychological distress-related death

Despite the significant scientific advancement in deciphering the "deaths of despair" narrative, most relevant studies have focused on drug-, alcohol-, and suicide-related (DAS) deaths. This study directly investigated despair as a determinant of death and the temporal variation and racial heterogeneity among individuals. We used psychological distress (PD) as a proxy for despair and drew data from the US National Health Interview Survey-Linked Mortality Files 1997 to 2014, CDC (Centers for Disease Control and Prevention) Multiple Cause of Death database 1997 to 2014, CDC bridged-race population files 1997 to 2014, Current Population Survey 1997 to 1999, and the American Community Survey 2000 to 2014. We used Cox proportional hazards models to estimate mortality hazard ratios of PD and compared age-standardized PD- and DAS-related mortality rates by race/ethnicity and over time. We found that while Whites had a lower prevalence of PD than Blacks and Hispanics throughout the whole period, they underwent distinctive increases in PD-related death and have had a higher PD-related mortality rate than Blacks and Hispanics since the early 2000s. This was predominantly due to Whites' relatively high and increasing vulnerability to PD less the prevalence of PD. Furthermore, PD induced a more pervasive mortality consequence than DAS combined for Whites and Blacks. In addition, PD- and DAS-related deaths displayed a concordant trend among Whites but divergent patterns for Blacks and Hispanics. These findings suggest that 1) DAS-related deaths underestimated the mortality consequence of despair for Whites and Blacks but overestimated it for Hispanics; and 2) despair partially contributed to the DAS trend among Whites but probably not for Blacks and Hispanics.

Editorial: Progress and Challenges in Characterizing Psychiatric Symptoms and Behaviors in Suicidal Preadolescent Children

Historically, little clinical and research attention has been focused on suicide in preadolescent children because of the commonly held view that children at this age do not possess the cognitive capacity fully to comprehend death (eg, its finality) and therefore are incapable of experiencing suicidal thoughts and behaviors.1 This view may result in expressions of suicidal thoughts by preadolescent children being interpreted and treated as momentary expressions of distress, but not of actual desire or intent to engage in suicidal behavior. There is accumulating evidence, however, to urge caution against such an interpretation. Although preadolescent suicide occurs at a low base rate, it has been increasing, rising from the 10th leading cause of death in this age group in 2008 to the 5th leading cause of death by 2019 in the United States according to data from the US Centers for Disease Control and Prevention.2 Furthermore, in the general community, suicidal thoughts and behaviors have been found to occur at concerningly high rates among preadolescent children in a recent systematic review, with lifetime prevalence of 2.6% for suicide attempts and 15.1% for suicidal thoughts.3 In this age group, another form of self-injurious thoughts and behaviors (SITBs), nonsuicidal self-injury (ie, deliberate self-harm in the absence of suicidal intent), is also poorly understood and a significant concern, with a lifetime prevalence of 6.3% among preadolescent children in the general community. Accurate characterization of the psychiatric symptom and behavioral profiles of preadolescents with SITBs is an important step toward identifying children in need of intervention or preventive efforts to avoid these outcomes.

Content and Process of Adolescent Suicide Ideation: Implications for Risk Assessment

This study examined differences in the content and process of suicide ideation between adolescents presenting with recent suicide ideation or a suicide attempt in clinical settings. Across two combined study samples, adolescents (N = 229; 79% female; 73% Hispanic/Latine), ages 12-19, presenting with a recent suicide attempt, recent suicide ideation with a past suicide attempt history, or recent suicide ideation with no past suicide attempt history were interviewed in detail about the process and content of their suicide ideation. The group with suicide ideation and a past suicide attempt more often reported that their recent ideation lasted greater than 4 h compared to those with suicide ideation but no past suicide attempt history. The suicide attempt group more often considered ingestion as their first method of attempt, compared to the other two suicide ideation groups, and less often considered "other" methods (e.g., jumping from a height or onto train/traffic, hanging). Wish to die was lower in the ideation-only group, compared to both other groups. Separate analyses from Study 2 suggested that the majority of adolescents' suicide ideation contained imagery; however, a higher proportion of adolescents with suicide ideation and a past suicide attempt reported imagery in their ideation than those with ideation but no past attempt. Understanding what adolescents think about when they consider suicide and how they think about it may be informative about risk of a suicide attempt.

Key Challenges and Potential Strategies for Engaging Youth with Lived Experience in Clinical Science

Centering the perspectives of youth with lived experience (YWLE) in psychopathology is critical to engaging in impactful clinical research to improve youth mental health outcomes. Over the past decade there has been a greater push in clinical science to include community members, and especially community members with lived experience, in all aspects of the research process. The goal of this editorial is to highlight the need for and importance of integrating YWLE into every stage of clinical science research, from idea generation to interpretation and dissemination of research findings. We identify five key problems associated with pursuing research on adolescent mental health without involvement of YWLE and propose strategies to overcome barriers to youth engagement in clinical science research. We conclude with a call to action, providing guidance to clinical scientists, institutions, and funding agencies in conducting research on youth psychopathology with YWLE.

Prospective Relation between Ruminative Subtypes and Suicide Ideation: Moderating Role of Problem Solving

Background

Although reflection has been characterized as a more adaptive subtype of rumination than brooding, evidence suggests that reflection is associated with suicide ideation. The present longitudinal study investigated the mediating role of hopelessness and depressive symptoms and the moderating role of problem solving in explaining why reflection may lead to suicide ideation.

Methods

Two hundred ninety-four undergraduates participated in the study and were followed up every 6 months over 18 months. Participants completed measures of brooding and reflection, hopelessness, depressive symptoms, problem solving, and suicide ideation.

Results

Results revealed that after adjusting for baseline suicide ideation, the serial mediation path from brooding (but not reflection) to suicide ideation via hopelessness and depressive symptoms was significant. Baseline reflection predicted suicide ideation 18 months later through depressive symptoms at 12 months for people average in passive problem solving, and for those low or average in active problem solving. Brooding predicted suicide ideation through depressive symptoms, regardless of problem-solving.

Conclusions

Reflection may result in suicide ideation via depressive symptoms among people with poor problem-solving skills. Clinical and theoretical implications are discussed.

Temporal Location of Changes in the US Suicide Rate by Age, Ethnicity, and Race: A Joinpoint Analysis 1999-2020

ABSTRACT

Suicide rates differ over time. Our objective was to determine when significant changes occurred by age, race, and ethnicity in the United States between 1999 and 2020. National Center for Health Statistics WONDER data were used in joinpoint regression. The annual percent change in suicide rate increased for all race, ethnic, and age groups, except for those 65 years and older. For American Indian/Alaska Natives, the largest increase occurred between 2010 and 2020 for those with ages 25 to 34 years. For Asian/Pacific Islander, the largest increase occurred among those 15 to 24 years old between 2011 and 2016. For Black/African-Americans, the largest increases occurred between 2010 and 2020 among 15- to 34-year-olds. For Whites, the largest increase occurred between 2014 and 2017 among 15- to 24-year-olds. Between 2018 and 2020, suicide rates significantly declined among Whites 45 to 64 years of age. Among Hispanics, significant increases in suicide rate occurred between 2012 and 2020 among those with ages 15 to 44 years. Between 1999 and 2020, the contour of suicide burden varied by age groups, race, and ethnicity.

Argyrophilic grain disease is common in older adults and may be a risk factor for suicide: a study of Japanese forensic autopsy cases

BACKGROUND

Neuropathological diagnosis of argyrophilic grain disease (AGD) is currently based primarily on the combination of argyrophilic grain (AG) visualized using Gallyas-Braak silver staining, phosphorylated tau-positive pretangles, coiled bodies, and ballooned neuron detection. Although AGD is common in patients with dementia and/or prominent psychiatric symptoms, whether it is a distinct neurological disease entity or a by-product of the aging process remains unclear.

METHODS

In 1449 serial forensic autopsy cases > 40 years old (823 males and 525 females, aged 40-101 years, mean age 70.0 ± 14.1 years), we examined the frequency and comorbid pathology of AGD cases and investigated the clinical appearance by comparing those with non-AGD cases using the propensity score.

RESULTS

Of the 1449 cases, we detected 342 AGD cases (23.6%; mean age 79.7 years; 177 males and 165 females). The AGD frequency and stage increased with age (P < 0.001). Among AGD cases, 80 (23.4%) patients had dementia, and 51 (15.2%) had a history of psychiatric hospital visits. The frequency of suicide and history of psychiatric disorders were significantly higher in AGD cases than in AGD-negative cases, matched for age, sex, and comorbidity pathology, with a relative risk of suicide of 1.72 (1.30-2.26). The frequency of suicide was significantly higher in AGD cases than in non-AGD cases in female but not male cases. The relative risk of suicide increased to 2.27 (1.20-4.30) and 6.50 (1.58-26.76) in AGD patients with Lewy and progressive supranuclear palsy pathology, respectively, and decreased to 0.88 (0.38-2.10) in those with advanced AD pathology. In AGD cases, 23.4% had dementia; however, the difference was not significant after controlling for age, sex, and comorbid pathology.

CONCLUSION

Our study demonstrated that AGD is a significant and isolated risk factor for psychiatric hospital visits and suicide completion. In older adults, AGs may contribute to the progression of functional impairment of the limbic system, which leads to psychiatric disorders and suicide attempts.

Self-reported anxiety and depression problems and suicide ideation among black and latinx adults and the moderating role of social support

Suicide is a critical public health problem. Over the past decade, suicide rates have increased among Black and Latinx adults in the U.S. Though depression is the most prevalent psychiatric contributor to suicide risk, Black and Latinx Americans uniquely experience distress and stress (e.g., structural adversity) that can independently operate to worsen suicide risk. This makes it important to investigate non-clinical, subjective assessment of mental health as a predictor of suicide ideation. We also investigate whether social support can buffer the deleterious impact of poor mental health on suicide ideation.We analyzed data from 1,503 Black and Latinx participants of the Washington Heights Community Survey, a 2015 survey of residents of a NYC neighborhood. Multivariable logistic regression was conducted to examine the effect of subjectively experienced problems with anxiety and depression on suicide ideation independent of depression diagnosis, and the role of social support as a moderator.Estimated prevalence of past two-week suicide ideation was 5.8%. Regression estimates showed significantly increased odds of suicide ideation among participants reporting moderate (OR = 8.54,95% CI = 2.44-29.93) and severe (OR = 16.84,95% CI = 2.88-98.46) versus no problems with anxiety and depression, after adjustment for depression diagnosis. Informational support, i.e., having someone to provide good advice in a crisis, reduced the negative impact of moderate levels of anxiety and depression problems on suicide ideation.Findings suggest that among Black and Latinx Americans, subjective feelings of anxiety and depression account for a significant portion of the suicide ideation risk related to poor mental health. Further, social support, particularly informational support, may provide protection against suicide ideation.

Examining Discrepant Reports of Adolescents' Self-Injurious Thoughts and Behaviors: A Focus on Racial and Ethnic Minority Families

INTRODUCTION

Adolescents and their parents do not always see eye to eye. This principle applies to multi-informant reports of adolescents' self-injurious thoughts and behaviors. Although prior work has revealed the presence of parent-adolescent discrepant reports, we have little insight into exactly who is most likely to display such discrepancies. To address this knowledge gap, the present investigation examines demographic correlates of parent-adolescent reports of adolescents' self-injurious thoughts and behaviors, with a focus on race and ethnicity.

METHOD

The sample included 45 dyads of adolescents (M = 15.79 years, SD = 1.42) and their parents reporting on adolescents' history of suicide ideation, suicide plan, suicide gesture, suicide attempt, and nonsuicidal self-injury (NSSI).

RESULTS

Greater discrepancies in reports of adolescents' suicide ideation and NSSI were observed among racial minority parent-adolescent dyads (Black, Asian, Multiracial, Other) relative to White dyads. Racial minority parents tended to report less suicide ideation and NSSI observed in their adolescents compared to adolescents' self-report. Moreover, Hispanic parents tended to report less NSSI relative to adolescents' self-report. Parent-adolescent discrepancies did not consistently correspond with other characteristics such as age and sexual orientation.

CONCLUSION

Racial minority parent-adolescent dyads, relative to White parent-adolescent dyads, are less likely to see eye to eye on adolescents' suicidal and nonsuicidal self-harming tendencies.

Suicidal and nonsuicidal self-harming thoughts and behaviors in clinically referred children and adolescents with gender dysphoria

BACKGROUND

Young transgender or gender nonconforming (TGNC) children and adolescents or those with a gender dysphoria (GD) diagnosis show an increased risk of suicidal and nonsuicidal self-harming thoughts and behaviors (STBs). Data from German-speaking regions on this topic and studies comparing self- and parent-reported STBs have been scarce. The study aims were therefore to examine: (a) frequencies of self- and parent-reported STBs in a German clinical sample of children and adolescents with GD and (b) differences between age and gender groups, as well as between self- and parent-reports.

METHODS

Two items from the Child Behavior Checklist (CBCL) and the Youth Self-Report (YSR) were used to assess self- and parent-reported STBs in a sample of 343 adolescents and 49 children who presented to the Hamburg Gender Identity Service (Hamburg GIS) between 2013 and 2019. Seventy-eight percent of the analysis sample was assigned female at birth (AFAB), and 22% were assigned male at birth (AMAB).

RESULTS

Parents reported STBs on the CBCL for 16% and 6% of the cases in childhood and for 20% and 29% of the adolescent cases, respectively. STBs were self-reported by 38% and 45% of the adolescents who could report on the YSR. STBs were higher among adolescents than among children and in self-reports (YSR) compared to parent reports (CBCL). AFAB adolescents reported higher degrees of STBs than AMAB adolescents.

CONCLUSIONS

Children and adolescents with GD are a high-risk population for STBs, especially pubescent and AFAB individuals. Mental health professionals should screen early for STBs to prevent possible suicidal ideation-to-action transitions.

The effect of social network strain on suicidal ideation among middle-aged adults with adverse childhood experiences in the US: A twelve-year nationwide study

Objective

Building on literature that measured the association between social network strain (SNS) and suicidal ideation using conventional regression analyses, we examined the effect of SNS, due to adverse childhood experiences (ACEs), on suicidal ideation using instrumental variables (IV) to eliminate the potential biases that may have occurred in earlier studies due to residual confounding.

Methods

This retrospective cohort study linked longitudinal data from the National Survey of Midlife Development in the United States (MIDUS) Refresher Biomarker Project (2012–2016), the MIDUS Refresher Project (2011–2014), the MIDUS 2 Biomarker Project (2004–2009), and the MIDUS 2 Project (2004–2006). Participants completed a phone interview, self-administered survey, and biomarker data collection. Exposure indicators included self-reported suicidal ideation, ACEs, and SNS from family, spouse, and friends. IV analysis was used to evaluate the continuous local average treatment effect of SNS on suicidal ideation when SNS only varied due to variation in ACEs.

Results

Our sample included 1703 middle-aged adults (52.9% females), which were followed up for 12 years. An IV probit model controlling for sociodemographic characteristics found a one-standard-deviation reduction in SNS reduced suicidal ideation by 22.6% (p < 0.01). A comprehensively controlled IV probit model found that a one-standard-deviation reduction in SNS is associated with a 21.4% (p = 0.05) decrease in suicidal ideation.

Conclusions

The causal pathway from SNS (due to ACEs) to suicidal ideation among middle-aged adults was established using IV analysis in this large-scale longitudinal study. The magnitude of this effect is sufficient to warrant the development of programs to improve social network relationships among family, friends, and spouses/partners. Suicide prevention programs addressing SNS may significantly reduce suicidal ideation among middle-aged Americans who have experienced ACEs.

•

Social Network Strain (SNS) from family, spouse, and friends is common.

•

SNS derives from demands, criticisms, disappointments, and irritations.

•

SNS varies strongly with Adverse Childhood Experiences (ACEs).

•

Reductions in SNS due to fewer ACEs decrease suicidal ideation.

•

A one standard-deviation reduction in SNS lowers suicidal ideation by 20%.

Factors precipitating suicide attempts vary across race

OBJECTIVE

Although research has identified interpersonal, intrapersonal, and achievement-related factors that precipitate suicide attempts (SAs), how these factors vary by race/ethnicity is unknown. We examined racial/ethnic differences in SA precipitants in a racially/ethnically diverse sample of young adults (YAs) with a SA history.

METHOD

Two-hundred twenty-nine young adults, ages 18-33 (87% women), reported their method of attempt, and 200 of those reported on their SA precipitants. The latter were coded by three independent judges (Data were collected March 2012-December 2016.).

RESULTS

SAs were most often precipitated by intrapersonal factors, followed by interpersonal factors. Logistic regressions revealed that Hispanic, Asian, and Biracial YAs had higher odds of reporting interpersonal precipitants compared to Black YAs.

CONCLUSION

Suicide prevention and intervention should address both interpersonal and intrapersonal factors that increase vulnerability to SA across racial/ethnic groups, although interventions with Black YAs might focus more on intrapersonal than on interpersonal factors.

A cycle of exclusion that impedes suicide research among racial and ethnic minority youth

In the United States, suicide risk for Black, Indigenous, and People of Color (BIPOC) is most concentrated before age 30, which contrasts with non-Hispanic White groups, for whom the highest risk period is during ages 50-65. The need for a better understanding of the underlying causes of suicidal behavior among BIPOC youth is critical. Cultural considerations were recommended over a decade ago to advance the study of youth suicide prevention and research. Without addressing the barriers to implementing these recommendations in limited-resourced settings, however, the mental health needs of BIPOC youth at risk for suicide will continue to go unmet. In this commentary, we outline structural barriers in research that perpetuate a cycle of exclusion wherein an understudied, though timely, research area faces undue burdens across the research cycle, which impedes the study of suicide risk among BIPOC youth.

Suicide Attempts Among Racial and Ethnic Groups in a Nationally Representative Sample

OBJECTIVE

Evaluate suicide attempt prevalence and potentially related sociodemographic and psychiatric factors among racial and ethnic groups.

METHODS

Between 2012 and 2013, the National Epidemiologic Survey on Alcohol and Related Conditions-III (NESARC-III) conducted semi-structured interviews with 36,309 adults in the USA. We identified lifetime suicide attempt prevalence and significant predictors for each racial/ethnic group using stratified logistic regressions. Analyses were exploratory without a priori hypotheses.

RESULTS

Asian/Native Hawaiian/other Pacific Islander and Black individuals had the lowest prevalence of suicide attempts while Alaska Native/American Indian and White individuals had the highest prevalence. Identifying as female and meeting criteria for psychiatric diagnoses featuring mood regulation difficulties (depression, borderline personality disorder, bipolar I disorder) were consistently related to a suicide attempt history across racial and ethnic groups, whereas substance abuse disorders and other sociodemographic factors differed between racial and ethnic groups in their associations with suicide attempt history.

CONCLUSIONS

Although several factors were consistently related to suicide risk across racial and ethnic groups, the prevalence of suicide attempts and overall pattern of related factors were not uniform between racial and ethnic groups.

POLICY IMPLICATIONS

Study findings highlight the importance of considering suicide risk within the context of race and ethnicity both regarding the overall prevalence of risk and in determining personal factors associated with elevated risk. A failure to appreciate experiences related to race and ethnicity may adversely impact suicide risk assessment and treatment, ultimately contributing to health disparities. Results suggest that additional research is warranted.

Sleep problems predict next-day suicidal thinking among adolescents: A multimodal real-time monitoring study following discharge from acute psychiatric care

Suicidal thoughts and behaviors (STBs) are major public health concerns among adolescents, and research is needed to identify how risk is conferred over the short term (hours and days). Sleep problems may be associated with elevated risk for STBs, but less is known about this link in youth over short time periods. The current study utilized a multimodal real-time monitoring approach to examine the association between sleep problems (via daily sleep diary and actigraphy) and next-day suicidal thinking in 48 adolescents with a history of STBs during the month following discharge from acute psychiatric care. Results indicated that specific indices of sleep problems assessed via sleep diary (i.e., greater sleep onset latency, nightmares, ruminative thoughts before sleep) predicted next-day suicidal thinking. These effects were significant even when daily sadness and baseline depression were included in the models. Moreover, several associations between daily-level sleep problems and next-day suicidal thinking were moderated by person-level measures of the construct. In contrast, sleep indices assessed objectively (via actigraphy) were either not related to suicidal thinking or were related in the opposite direction from hypothesized. Together, these findings provide some support for sleep problems as a short-term risk factor for suicidal thinking in high-risk adolescents.

Advances in Research on Adolescent Suicide and a High Priority Agenda for Future Research

Suicide is the second leading cause of death for adolescents in the United States, yet remarkably little is known regarding risk factors for suicidal thoughts and behaviors (STBs), relatively few federal grants and scientific publications focus on STBs, and few evidence-based approaches to prevent or treat STBs are available. This "decade in review" article discusses five domains of recent empirical findings that span biological, environmental, and contextual systems and can guide future research in this high priority area: (1) the role of the central nervous system; (2) physiological risk factors, including the peripheral nervous system; (3) proximal acute stress responses; (4) novel behavioral and psychological risk factors; and (5) broader societal factors impacting diverse populations and several additional nascent areas worthy of further investigation.

Being certain that negative events will happen or that positive events will not happen: Depressive predictive certainty and change in suicide ideation over time

INTRODUCTION

Relatively little research has examined the precise components of hopelessness that increase vulnerability to suicidal thinking. We examined whether certainty about an absence of positive future outcomes (Certainty-AP) would more strongly predict suicide ideation over time than certainty about negative future outcomes (Certainty-N).

METHOD

Young adults (N = 208), ages 18-34 (M = 19.08, SD = 2.22), with either recent suicide ideation, suicide attempt history, or past-year psychiatric diagnosis were assessed four times over 18 months.

RESULTS

We used multilevel modeling to assess within-participant differences in suicide ideation over time. Both Certainty-AP and Certainty-N predicted later suicide ideation above and beyond generalized hopelessness and depressive symptoms, when examined in separate models. However, Certainty-AP emerged as a stronger predictor of suicide ideation than Certainty-N when examined in the same model.

DISCUSSION

These findings suggest that certainty about an absence of positive future outcomes may have a more unique prospective relationship to SI than certainty about the presence of negative future outcomes. We discuss clinical and theoretical implications of these findings.

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.

Suicidal Behavior and Coming Out Milestones in Three Cohorts of Sexual Minority Adults

Purpose: We describe the timing of suicidality across the life span in three cohorts of sexual minority adults. We hypothesized that suicide attempts coincide with the coming out period and that younger sexual minority people, who grew up in more accepting social environments, will have lower prevalence of suicide attempts than older generations. Methods: A U.S. national probability sample of 1518 sexual minority adults in three age cohorts of 18-25, 34-41, and 52-59 years (collected 2016-2018) completed a self-administered survey. Results: Sexual minority adults had high prevalence of lifetime suicidal thoughts, plans, and attempts, with the highest attempted suicides in the younger cohort (30.8%, 95% confidence interval [CI] = 26.8-35.1) compared with the middle (23.7%, 95% CI = 19.0-29.1) and older (20.3%, 95% CI = 16.3-25.1) cohorts. There were no differences in suicidal behavior by race and ethnicity or between men and women, but gender nonbinary people had higher prevalence of suicidal thoughts. The mean age at suicidal thoughts, plans, and attempts tracked closely with age of first realization of sexual minority identity. Most suicide attempts (60.9%) occurred within 5 years of realizing one's sexual minority identity, but a significant proportion of attempts (39.1%) occurred outside this range. Conclusion: Our findings are contrary to the hypothesis that younger cohorts of sexual minority people are at lower risk of suicidality.

Deconstructing the role of the exposome in youth suicidal ideation: Trauma, neighborhood environment, developmental and gender effects

Environment (E) is pivotal in explaining variability in brain and behavior development, including suicidal ideation (SI) and behavior. It is therefore critical to systematically study relationships among environmental exposures (i.e., exposome) and suicidal phenotypes. Here, we evaluated the role of individual-level adversity and neighborhood environment and their interaction (E x E) in association with youth SI. Sample included youth (N = 7,054, ages 11–21) from the Philadelphia Neurodevelopmental Cohort, which investigated clinical phenotypes in a diverse US community population. We examined cross-sectional associations of environmental exposures with lifetime history of SI (n = 671), focusing on interactions between individual-level exposures to assaultive trauma (n = 917) and neighborhood-level socioeconomic status (SES) quantified using geocoded Census data. Models included potential confounds and overall psychopathology. Results showed that assaultive trauma was strongly associated with SI (OR = 3.3, 95%CI 2.7–4, p < .001), while low SES was not (p = .395). Both assault and low SES showed stronger association with SI in females, and in early adolescence (all E X gender/age interactions, p < .05). In traumatized youths, lower SES was associated with less SI, with no SES effects on SI in non-traumatized youths (Assault X SES interaction, Wald = 8.19, p = .004). Associations remained significant controlling for overall psychopathology. No single SES variable emerged above others to explain the moderating effect of SES. These findings may suggest a stress inoculation effect in low SES, where youths from higher SES are more impacted by the deleterious trauma-SI association. Determining which environmental factors contribute to resilience may inform population specific suicide prevention interventions. The cross-sectional study design limits causal inferences.

•

Environment (E) is key in shaping development of suicidal ideation (SI).

•

We integrated individual-level trauma exposure and neighborhood-level data on socioeconomic status (SES) in N=7,054 youths.

•

Trauma was robustly associated with youth SI in our cohort, while SES had no association with SI.

•

Only in youth with history of assaultive trauma, low SES was associated with lower SI rates (trauma by SES interaction).

•

Results suggest a stress inoculation effect that was shown in animal models, but has not been shown in human suicide research.

Adolescent social networks matter for suicidal trajectories: disparities across race/ethnicity, sex, sexual identity, and socioeconomic status

BACKGROUND

Examining social networks, characterized by interpersonal interactions across family, peer, school, and neighborhoods, offer alternative explanations to suicidal behaviors and shape effective suicide prevention. This study examines adolescent social networks predicting suicide ideation and attempt trajectories transitioning to adulthood, while revealing differences across racial/ethnic, sex, sexual identity, and socioeconomic status.

METHODS

Participants included 9421 high school students (Mage = 15.30 years; 54.58% females, baseline) from Waves I-IV of the National Longitudinal Study of Adolescent to Adult Health, 1994-2008. Latent class growth analyses were conducted to identify suicide ideation and attempt trajectories. Multivariate multinomial logistic regressions examined the relationships between social network characteristics during adolescence and suicidal trajectories. Interaction terms between social networks and sociodemographic characteristics were included to test moderation effects.

RESULTS

Three suicidal ideation trajectories (low-stable, high-decreasing, moderate-decreasing-increasing) and two suicide attempt trajectories (low-stable, moderate-decreasing) were identified. Greater family cohesion significantly reduced the probability of belonging to high-decreasing (Trajectory 2) and moderate-decreasing-increasing (Trajectory 3) suicidal ideation trajectories, and moderate-decreasing (Trajectory 2) suicide attempt trajectory. Race/ethnicity, sex, and sexual identity significantly moderated the associations between social networks (household size, peer network density, family cohesion, peer support, neighborhood support) and suicidal trajectories.

CONCLUSIONS

Social networks during adolescence influenced the odds of belonging to distinct suicidal trajectories. Family cohesion protected youth from being in high-risk developmental courses of suicidal behaviors. Social networks, especially quality of interactions, may improve detecting adolescents and young adults at-risk for suicide behaviors. Network-based interventions are key to prevent suicidal behaviors over time and suicide intervention programming.

Sleep and suicide: A systematic review and meta-analysis of longitudinal studies

The current review provides a quantitative synthesis of the empirical literature on sleep disturbance as a risk factor for suicidal thoughts and behaviors (STBs). A systematic search of PsycINFO, MEDLINE, and the references of prior reviews resulted in 41 eligible studies included in this meta-analysis. Sleep disturbance, including insomnia, prospectively predicted STBs, yielding small-to-medium to medium effect sizes for these associations. Complicating interpretation of these findings however, is that few studies of suicidal ideation and suicide attempts, as well as none of suicide deaths, assessed short-term risk (i.e., employed follow-up assessments of under a month). Such studies are needed to evaluate current conceptualizations of sleep dysregulation as being involved in acute risk for suicidal behavior. This want of short-term risk studies also suggests that current clinical recommendations to monitor sleep as a potential warning sign of suicide risk has a relatively modest empirical basis, being largely driven by cross-sectional or retrospective research. The current review ends with recommendations for generating future research on short-term risk and greater differentiation between acute and chronic aspects of sleep disturbance, and by providing a model of how sleep disturbance may confer risk for STBs through neuroinflammatory and stress processes and associated impairments in executive control.

Predicting suicidal behavior among lesbian, gay, bisexual, and transgender youth receiving psychiatric emergency services

Lesbian, gay, bisexual, and transgender (LGBT) youth are at elevated risk for self-injurious thoughts and behaviors (SITBs). However, few studies have comprehensively examined SITBs and their longitudinal course in LGBT youth at high risk for suicide. The aims of the present study were to characterize histories of SITBs among high-risk LGBT youth and to examine prospective associations with suicidal behavior. Participants were 285 youth (41.8% LGBT) ages 13-25 years receiving psychiatric emergency department (ED) services. Post-discharge suicidal behavior was assessed via 4-month phone interviews and 12 month chart reviews. The sample was 42.1% male, 57.9% female, 2.5% gender minority, 41.8% sexual minority. LGBT participants were more likely to have prior psychiatric ED visits and hospitalizations, more frequent past week suicide ideation, and more severe nonsuicidal self-injury (NSSI). We conducted stratified survival analyses to identify predictors of time to suicidal behavior post discharge. The final model for LGBT youth included past week suicide ideation and past month NSSI episodes. Among non-LGBT youth, the final model included number of lifetime NSSI methods and use of a highly lethal suicide attempt method. Within this sample of youth receiving psychiatric emergency services, LGBT youth were overrepresented and had more severe histories of SITBs. Results suggest the importance of assessing both lifetime and recent factors (i.e., past week and month), particularly for LGBT youth. Future research should replicate these findings in larger samples to explore whether there are unique risk factors that can aid in predicting and preventing suicide among LGBT youth.

Suicidality in a Community Sample of Early Adolescents: A Three-Phase Follow-Up Study

The aim of the study was to collect data on suicidal ideation and suicidal risk prevalence in a three-phase epidemiological study. In the first phase, 1,514 participants (720 boys; mean-age = 10.2) filled out the Children's Depression Inventory (CDI) and other psychopathological tests. 562 individuals (mean-age = 11.3) were selected to participate in the second phase as at-risk individuals of emotional disorders or as controls, and the CDI and the Mini-International Neuropsychiatric Interview for Children and Adolescents (M.I.N.I.-Kid) were administered. In the third phase the participants (245; mean-age = 13.5) filled out the Youth's Inventory-4. The results of the CDI indicated that 15.9% of the participants showed suicidal ideation in the first phase, and 18.2% and 18.0% in the second and third phases, respectively. 33.0% of the participants persisted at 1 year of follow-up with suicidal ideation. The M.I.N.I.-Kid showed 12.2% past suicidal risk and a current risk of 2.4%. The current suicidal risk was mainly related to depressive disorders (OR 30.3). Predictors of current suicidal risk for boys included having previous depressive symptoms. For girls predictors included having previous anxiety and obsessive-compulsive symptoms, suicidal ideation and lower socioeconomic status. Spanish early adolescents had relevant rates of suicidal behavior; thus, it is important to create and apply prevention programs that consider the risk factors.

Racial/Ethnic Discrimination and Suicidal Ideation in Emerging Adults: The Role of Traumatic Stress and Depressive Symptoms Varies by Gender not Race/Ethnicity

Drawing from Race-Based Traumatic Stress theory, the present study examined whether traumatic stress and depressive symptoms differentially help explain the relation between racial/ethnic discrimination and suicidal ideation across gender and racial/ethnic groups. A racially/ethnically diverse group of emerging adults (N = 1344; M_age = 19.88, SD = 2.25; 72% female; 46% Hispanic) completed a battery of self-report measures. A cross-sectional design was employed with a series of hierarchical linear regression models and bootstrapping procedures to examine the direct and indirect relation between racial/ethnic discrimination and suicidal ideation through traumatic stress and depressive symptoms across gender and race/ethnicity. The findings suggest an indirect relation through depressive symptoms, but not traumatic stress, and a serial indirect relation through traumatic stress to depressive symptoms in young women and young men, the latter of which was stronger in young women. The indirect relations did not vary by racial/ethnic group. Cumulative experiences of racial/ethnic discrimination may impact suicide-related risk via increases in psychiatric symptomology (i.e., traumatic stress and depressive symptoms), particularly in young women. Racial/ethnic discrimination experiences should be accounted for as a potential source of psychological distress in the assessment, diagnosis, and treatment of suicidal thoughts and behavior, especially among young women endorsing traumatic stress and depressive symptoms. Further research is warranted to better understand the gender difference in the relation between racial/ethnic discrimination and suicide-related risk.

Suicide in Transgender Veterans: Prevalence, Prevention, and Implications of Current Policy

Transgender adults serve in the U.S. military at 2 to 3 times the rate of the general adult population. Unfortunately, transgender veterans die by suicide at twice the rate of their cisgender veteran peers and approximately 5.85 times the rate of the general population. This article reviews the literature regarding the prevalence of suicidal thoughts and behaviors in transgender veterans. Suicide risk and resilience factors are reviewed, and future areas of study are detailed that incorporate findings from the broader suicide-prevention literature and research on transgender mental-health disparities. Individual services and broader prevention considerations are discussed, including the adaptation of evidence-based suicide-specific psychological interventions, national transgender health-training resources, and relevant veteran suicide-prevention initiatives. Finally, U.S. Department of Defense and U.S. Department of Veterans Affairs policies regarding transgender service and health care are reviewed. State-level policies relevant to transgender veteran suicide such as firearm ownership and nondiscrimination laws are also reviewed, and their implications for suicide prevention are discussed. The aim of this article is to provide a broad review of research findings from multiple fields of study to assist health-care providers, researchers, and policymakers in their efforts to prevent transgender veteran suicide.

Annual Research Review: Suicide among youth - epidemiology, (potential) etiology, and treatment

BACKGROUND

Suicide is a leading cause of death and a complex clinical outcome. Here, we summarize the current state of research pertaining to suicidal thoughts and behaviors in youth. We review their definitions/measurement and phenomenology, epidemiology, potential etiological mechanisms, and psychological treatment and prevention efforts.

RESULTS

We identify key patterns and gaps in knowledge that should guide future work. Regarding epidemiology, the prevalence of suicidal thoughts and behaviors among youth varies across countries and sociodemographic populations. Despite this, studies are rarely conducted cross-nationally and do not uniformly account for high-risk populations. Regarding etiology, the majority of risk factors have been identified within the realm of environmental and psychological factors (notably negative affect-related processes), and most frequently using self-report measures. Little research has spanned across additional units of analyses including behavior, physiology, molecules, cells, and genes. Finally, there has been growing evidence in support of select psychotherapeutic treatment and prevention strategies, and preliminary evidence for technology-based interventions.

CONCLUSIONS

There is much work to be done to better understand suicidal thoughts and behaviors among youth. We strongly encourage future research to: (1) continue improving the conceptualization and operationalization of suicidal thoughts and behaviors; (2) improve etiological understanding by focusing on individual (preferably malleable) mechanisms; (3) improve etiological understanding also by integrating findings across multiple units of analyses and developing short-term prediction models; (4) demonstrate greater developmental sensitivity overall; and (5) account for diverse high-risk populations via sampling and reporting of sample characteristics. These serve as initial steps to improve the scientific approach, knowledge base, and ultimately prevention of suicidal thoughts and behaviors among youth.

Demographics as predictors of suicidal thoughts and behaviors: A meta-analysis

BACKGROUND

Certain demographic factors have long been cited to confer risk or protection for suicidal thoughts and behaviors. However, many studies have found weak or non-significant effects. Determining the effect strength and clinical utility of demographics as predictors is crucial for suicide risk assessment and theory development. As such, we conducted a meta-analysis to determine the effect strength and clinical utility of demographics as predictors.

METHODS

We searched PsycInfo, PubMed, and GoogleScholar for studies published before January 1st, 2015. Inclusion criteria required that studies use at least one demographic factor to longitudinally predict suicide ideation, attempt, or death. The initial search yielded 2,541 studies, 159 of which were eligible. A total of 752 unique statistical tests were included in analysis.

RESULTS

Suicide death was the most commonly studied outcome, followed by attempt and ideation. The average follow-up length was 9.4 years. The overall effects of demographic factors studied in the field as risk factors were significant but weak, and that of demographic factors studied as protective factors were non-significant. Adjusting for publication bias further reduced effect estimates. No specific demographic factors appeared to be strong predictors. The effects were consistent across multiple moderators.

CONCLUSIONS

At least within the narrow methodological constraints of the existing literature, demographic factors were statistically significant risk factors, but not protective factors. Even as risk factors, demographics offer very little improvement in predictive accuracy. Future studies that go beyond the limitations of the existing literature are needed to further understand the effects of demographics.
