From Adversity to Suicidality: Differential Effects of ACE Subtypes on Suicidal Thoughts and Behaviors among Adolescents in the United States

Technical Summary: From Adversity to Suicidality

Problem Statement
Suicidal thoughts and behaviors (STBs) represent a critical public health crisis among adolescents in the United States, ranking as a leading cause of death for youth aged 10–19. While the link between Adverse Childhood Experiences (ACEs) and negative mental health outcomes is well-established, existing literature relies heavily on cumulative ACE scores. This approach obscures the heterogeneous effects of specific adversity subtypes and fails to adequately address how distinct forms of adversity—ranging from household dysfunction to community violence—are differentially distributed across racial and ethnic groups. Furthermore, there is a paucity of research utilizing recent national data to simultaneously examine household- and community-level adversities while controlling for co-occurring psychosocial risk factors such as bullying and emotional distress.

Methodology
This study utilized a cross-sectional design drawing from the 2023 Youth Risk Behavior Survey (YRBS), a nationally representative sample of U.S. high school students. The final analytic sample consisted of 19,928 adolescents aged 14–18.

• Data Handling: Missing data (ranging from <1% to 33.3%) were addressed using Multiple Imputation by Chained Equations (MICE), generating 20 imputed datasets. Weighted logistic regression models were employed to account for the complex cluster sampling design of the YRBS.
• Outcome Variables: Three binary outcomes were examined: suicidal ideation, suicide planning, and suicide attempts (all measured within the past 12 months).
• Explanatory Variables: The study disaggregated ACEs into nine specific domains: emotional abuse, physical abuse, sexual abuse, physical neglect, witnessing intimate partner violence (IPV), household substance use, household poor mental health, household member incarceration/detention, and exposure to neighborhood violence.
• Covariates: Models adjusted for demographic variables (age, sex, sexual identity, race/ethnicity) and psychosocial factors (school bullying, cyberbullying, and persistent sadness/hopelessness).
• Theoretical Framework: The analysis was guided by Socioecological Systems Theory (Bronfenbrenner) and the Interpersonal-Psychological Theory of Suicide (IPTS; Joiner).

Key Results

• Prevalence: In the past year, 21.5% of adolescents reported suicidal ideation, 17.5% reported suicide planning, and 10.4% reported at least one suicide attempt.
• Racial/Ethnic Disparities: Significant disparities in ACE exposure were observed. American Indian/Alaska Native (AIAN), Black, Hispanic, and "Other" racial/ethnic groups reported elevated exposure across multiple ACE domains compared to non-Hispanic White adolescents. Notably, AIAN adolescents showed the highest prevalence in physical neglect, household substance use, household poor mental health, and household incarceration.
• ACE Subtypes and STBs: After adjusting for covariates, specific ACE domains showed distinct associations with STBs:
  • Emotional Abuse: Consistently associated with increased odds of suicidal ideation, planning, and attempts.
  • Sexual Abuse: Demonstrated the strongest association with suicide attempts (AOR = 2.23).
  • Physical Neglect: Significantly associated with suicide planning and attempts.
  • Physical Abuse: Associated with suicide attempts only.
  • Neighborhood Violence: Consistently associated with increased odds across all three STB outcomes.
  • Household Factors: Household poor mental health was linked to ideation and planning, while household substance use was linked only to ideation. Witnessing IPV and household incarceration were not significantly associated with STBs after adjustment.
• Psychosocial Correlates: Persistent sadness/hopelessness emerged as the strongest correlate of all STBs (AORs ranging from 6.87 to 9.18). Sexual minority status (bisexual, lesbian/gay, questioning) was independently associated with higher odds of all STBs compared to heterosexual peers.
• Demographic Findings: Black adolescents had 1.47 times higher odds of suicide attempts compared to White adolescents. Conversely, Hispanic adolescents had lower odds of suicidal ideation compared to White adolescents, a finding the authors suggest may reflect the "Hispanic paradox."

Key Contributions

1. Disaggregation of ACEs: The study moves beyond cumulative scoring to demonstrate that specific ACE subtypes exert distinct effects on different dimensions of suicidality (ideation vs. planning vs. attempts).
2. Integration of Ecological Levels: By including neighborhood violence alongside traditional household adversities, the study highlights the role of macrosystemic factors in adolescent suicide risk.
3. Racial/Ethnic Specificity: The research explicitly maps how structural inequities result in differential exposure to specific adversities across racial/ethnic groups, providing a more nuanced understanding of health disparities.
4. Psychosocial Context: The study accounts for the independent and potent effects of bullying and persistent sadness, identifying hopelessness as a primary driver of STBs.

Significance and Claims
The authors claim that their findings underscore the necessity of moving from general ACE assessments to targeted, trauma-informed interventions that address specific domains of adversity. They argue that:

• Interpersonal and Community Trauma: Direct interpersonal traumas (abuse, neglect) and community-level violence are particularly salient drivers of suicidality, supporting the IPTS concept of "acquired capability" through habituation to fear and pain.
• Culturally Responsive Interventions: Given the disproportionate exposure of minoritized youth to adversity, prevention strategies must be culturally responsive and address structural racism and community disinvestment.
• Multilevel Approach: Effective suicide prevention requires a shift from individual-level interventions to multilevel strategies that target family environments, school climates (specifically bullying), and structural inequities.

The paper concludes with modest limitations, acknowledging the cross-sectional nature of the data which precludes causal inference, the potential for recall bias in self-reported ACEs, and the possibility of unmeasured confounding variables inherent in secondary data analysis.
