Adverse childhood experiences (ACEs) are common and can impact health across the life course. Thus, it is essential for professionals in child- and family-serving roles, including pediatric and adult primary care clinicians, to understand the health implications of childhood adversity and trauma and respond appropriately. Screening for ACEs in health care settings has received attention as a potential approach to ACEs identification and response. Careful examination of the existing evidence on ACEs screening and consideration, from a clinical and ethical perspective, of the potential benefits, challenges, and harms is critical to ensuring evidence-informed practice. In this critical appraisal, we synthesize existing systematic and scoping reviews on ACEs screening, summarize recent studies on the ability of ACEs to predict health outcomes at the individual level, and provide a comprehensive overview of potential benefits, challenges, and harms of ACEs screening. We identify gaps in the existing evidence base and specify directions for future research. We also describe trauma-informed, relational care as an orientation and perspective that can help pediatric and primary care clinicians to sensitively assess for and respond to ACEs and other potentially traumatic experiences. Overall, we do not yet have sufficient evidence regarding the potential benefits, challenges, and harms of ACEs screening in health care and other settings. In the absence of this evidence, we cannot assume that screening will not cause harm and that potential benefits outweigh potential harms.

OBJECTIVE: Adverse childhood experiences (ACEs) are preventable, potentially traumatic events with lifelong negative impacts. Population-level data on ACEs among adolescents have historically relied on parent reports and excluded abuse-related ACEs. We present the self-reported prevalence of ACEs among a large population-based sample of US high school students. METHODS: Using cross-sectional, state-representative data from 16 states that included core ACE questions on their 2021 Youth Risk Behavior Survey, we estimate the prevalence of 8 individual (lifetime emotional, physical, or sexual abuse, physical neglect, witnessed intimate partner violence, household substance use, household poor mental health, incarcerated parent or guardian) and cumulative ACEs (0, 1, 2-3, ≥4) among a large population-based sample of adolescents, overall and by demographic characteristics (sex, race and ethnicity, age, sexual orientation). RESULTS: Emotional abuse (65.8%), household poor mental health (36.1%), and physical abuse (32.5%) had the highest prevalence. ACEs were very common, with 80.5% of adolescents experiencing at least 1 ACE and 22.4% experiencing ≥4 ACEs. Experiencing ≥4 ACEs was highest among adolescents who were female (27.7%), non-Hispanic multiracial (33.7%), non-Hispanic American Indian or Alaska Native (27.1%), gay or lesbian (36.5%), bisexual (42.1%), or who described their sexual identity some other way or were not sure of their sexual identity (questioning) (36.5%). CONCLUSIONS: Self-reported ACE estimates among adolescents exceed previously published parent-reported estimates. ACEs are not equally distributed, with important differences in individual and cumulative ACEs by demographic characteristics. Collecting ACE data directly from adolescents at the state level provides actionable data for prevention and mitigation.

Adverse childhood experiences (ACEs) are preventable, potentially traumatic events occurring before age 18 years. Data on ACEs among adolescents in the United States have primarily been collected through parent report and have not included important violence-related ACEs, including physical, sexual, and emotional abuse. This report presents the first national prevalence of self-reported ACEs among U.S. high school students aged <18 years, estimates associations between ACEs and 16 health conditions and risk behaviors, and calculates population-attributable fractions of ACEs with these conditions and behaviors using cross-sectional, nationally representative 2023 Youth Risk Behavior Survey data. Exposures were lifetime prevalence of individual (emotional, physical, and sexual abuse; physical neglect; witnessed intimate partner violence; household substance use; household poor mental health; and incarcerated or detained parent or guardian) ACEs and cumulative ACEs count (zero, one, two or three, or four or more). Health conditions and risk behaviors included violence risk factors, substance use, sexual behaviors, weight and weight perceptions, mental health, and suicidal thoughts and behaviors. Bivariate analyses assessed associations between individual and cumulative ACEs and demographics. Adjusted prevalence ratios assessed associations between cumulative ACEs and health conditions and risk behaviors, accounting for demographics. Population-attributable fractions were calculated to determine the potential reduction in health conditions and risk behaviors associated with preventing ACEs. ACEs were common, with approximately three in four students (76.1%) experiencing one or more ACEs and approximately one in five students (18.5%) experiencing four or more ACEs. The most common ACEs were emotional abuse (61.5%), physical abuse (31.8%), and household poor mental health (28.4%). Students who identified as female; American Indian or Alaska Native; multiracial; or gay or lesbian, bisexual, questioning, or who describe their sexual identity in some other way experienced the highest number of ACEs. Population-attributable fractions associated with experiencing ACEs were highest for suicide attempts (89.4%), seriously considering attempting suicide (85.4%), and prescription opioid misuse (84.3%). ACEs are prevalent among students and contribute substantially to numerous health conditions and risk behaviors in adolescence. Policymakers and public health professionals can use these findings to understand the potential public health impact of ACEs prevention to reduce adolescent suicidal behaviors, substance use, sexual risk behaviors, and other negative health conditions and risk behaviors and to understand current effects of ACEs among U.S. high school students.

The strength of American Indian and Alaska Native (AI/AN) communities comes from generations of Indigenous traditions, language, culture, and knowledge. These strengths have been challenged by a complex set of systemic, structural, and social factors related to historical and intergenerational trauma that affects the health of AI/AN communities. Furthermore, AI/AN population health data often are inaccurate because of analytic coding practices that do not account for multiracial and ethnic AI/AN identification and inadequate because of statistical suppression. The 2023 national Youth Risk Behavior Survey included a supplemental sample of AI/AN high school students. Coding of race and ethnicity was inclusive of all AI/AN students, even if they also identified as another race or as Hispanic or Latino, providing comprehensive data on health behaviors and experiences among AI/AN high school students nationwide. Adult caretaker engagement and school connectedness and their association with 13 health behaviors and experiences were examined, including five types of current substance use, four indicators of emotional well-being and suicide risk, and four types of violence. Pairwise t-tests and adjusted prevalence ratios from logistic regression models identified significant associations between exposure and outcome variables. Among AI/AN students, having an adult who always tried to meet their basic needs, high parental monitoring, and high school connectedness were associated with lower prevalence of certain measures of substance use, poor emotional well-being and suicide risk, and violence. Compared with non-AI/AN students, the prevalence of current electronic vapor product use, current marijuana use, attempted suicide, and experience of sexual violence was higher among AI/AN students.This report presents the most comprehensive, up-to-date data on substance use, indicators of emotional well-being and suicide risk, and experiences with violence among AI/AN high school students nationwide. The findings suggest the importance of engaged household adults and school connectedness in promoting emotional well-being and preventing substance use, suicide-related behavior, and experiences of violence among AI/AN students. Understanding the historical context and incorporating Indigenous knowledge when developing interventions focused on AI/AN youths are critical to ensure such interventions are successful in improving AI/AN health and well-being.

PURPOSE: Adverse childhood experiences (ACEs) increase the risk for poor mental health (MH) and substance use. We describe relationships between adolescents' ACEs, substance use, and poor MH occurring during the COVID-19 pandemic. METHODS: We conducted a secondary analysis of data among U.S. high school students aged <18 years, who participated in the nationally representative Adolescent Behaviors and Experiences Survey. Data were collected from January to June 2021. Bivariate and multivariable analyses assessed associations between individual ACEs (physical, emotional abuse by parent or caregiver, parent or caregiver job loss, food insecurity, sexual violence, physical dating violence, or cyber bullying) and cumulative ACEs (0, 1-2, 3, 4+) experienced during the pandemic and substance use; stratified analyses assessed effects of poor MH on associations between ACEs and substance use. RESULTS: Use of all substances was higher among adolescents with ACEs, particularly those who experienced both ACEs and poor MH during the COVID-19 pandemic. Prevalence of substance use was especially high among adolescents exposed to any sexual violence or physical dating violence. Compared to adolescents without ACEs, a higher percentage of adolescents with 4+ ACEs reported current use of alcohol (adjusted prevalence ratio [aPR], 5.32) or marijuana (aPR, 5.86), misuse of prescription pain medications (aPR, 8.82), binge drinking (aPR, 7.70), and increased alcohol (aPR, 6.54) or drug (aPR, 7.09) use during the pandemic. DISCUSSION: The individual and combined impact of ACEs and MH on adolescent substance use reinforce the need for trauma-informed care and primary prevention of ACEs to prevent and mitigate poor MH and substance use among adolescents.

Adverse childhood experiences (ACEs), suicide and overdose are linked across the life course and across generations and share common individual-, interpersonal-, community- and societal-level risk factors. The purpose of this review is to summarise the shared aetiology of these public health issues, synthesise evidence regarding potential community- and societal-level prevention strategies and discuss future research and practice directions.Growing evidence shows the potential for community- and societal-level programmes and policies, including higher minimum wage; expanded Medicaid eligibility; increased earned income tax credits, child tax credits and temporary assistance for needy families benefits; Paid Family Leave; greater availability of affordable housing and rental assistance; and increased participation in the Supplemental Nutrition Assistance Program (SNAP), to contribute to ACEs, suicide and overdose prevention. Considerations for future prevention efforts include (1) expanding the evidence base through rigorous research and evaluation; (2) assessing the implications of prevention strategies for equity; (3) incorporating a relational health perspective; (4) enhancing community capacity to implement, scale and sustain evidenced-informed prevention strategies; and (5) acknowledging that community- and societal-level prevention strategies are longer-term strategies.

Positive childhood experiences (PCEs) have substantial potential to improve children’s mental health. We examined the prevalence of 26 specific PCEs, overall and by demographics, and the individual and cumulative effects of PCEs with current diagnosis of three mental health conditions using nationally representative, parent-reported data on U.S. children aged 6–17 years from the 2018–2019 National Survey of Children’s Health (n=35,583). The prevalence of each PCE varied, with a range between 22.6% (gets recommended amount of physical activity) to 92.1% (parent(s) have positive mental health). Accounting for demographics, there were associations between most specific PCEs and lower prevalence of current childhood anxiety (22 of 26 PCEs), depression (22 of 26 PCEs), and behavioral or conduct problems (21 of 26 PCEs). There was a dose-response relationship between children in higher cumulative PCE quartiles and lower proportions of anxiety, depression, and behavioral or conduct problems. Findings generally did not attenuate after further adjusting for adverse childhood experiences. PCEs are common among U.S. children, but vary substantially by type of PCE and subpopulation. This has critical implications for focusing prevention and intervention strategies to bolster PCEs in ways that could improve health equity and children’s mental health. © This is a U.S. Government work and not under copyright protection in the US; foreign copyright protection may apply 2024.

Positive childhood experiences (PCEs) promote optimal health and mitigate the effects of adverse childhood experiences, but PCE prevalence in the United States is not well-known. Using Behavioral Risk Factor Surveillance System data, this study describes the prevalence of individual and cumulative PCEs among adults residing in four states: Kansas (2020), Montana (2019), South Carolina (2020), and Wisconsin (2015). Cumulative PCE scores were calculated by summing affirmative responses to seven questions. Subscores were created for family-related (three questions) and community-related (four questions) PCEs. The prevalence of individual PCEs varied from 59.5% (enjoyed participating in community traditions) to 90.5% (adult in respondents' household made them feel safe), and differed significantly by race and ethnicity, age, and sexual orientation. Fewer non-Hispanic Black or African American (49.2%), non-Hispanic Alaska Native or American Indian (37.7%), and Hispanic or Latino respondents (38.9%) reported 6-7 PCEs than did non-Hispanic White respondents (55.2%). Gay or lesbian, and bisexual respondents were less likely than were straight respondents to report 6-7 PCEs (38.1% and 27.4% versus 54.7%, respectively). A PCE score of 6-7 was more frequent among persons with higher income and education. Improved understanding of the relationship of PCEs to adult health and well-being and variation among population subgroups might help reduce health inequities.

Although current policies discourage the use of corporal punishment (CP), its use is still widespread in the US. The objective of this study was to assess the proportion of parents who used CP during the pandemic and identify related risk and protective factors. We analyzed results of a nationwide cross-sectional internet panel survey of 9000 US caregivers who responded in three waves from November 2020 to July 2021. One in six respondents reported having spanked their child in the past week. Spanking was associated with intimate partner violence and the use of multiple discipline strategies and not significantly associated with region or racial self-identification. Parents who spanked sought out more kinds of support, suggesting an opportunity to reduce spanking through more effective parenting resources. Additionally, these results suggest that parents who report using CP may be at risk for concurrent domestic violence.

Teen dating violence (TDV) is a significant public health problem that can have lifelong consequences. Using a longitudinal, cluster randomized controlled trial (RCT), this study examines whether the Dating Matters comprehensive prevention model, implemented in middle school, prevented TDV and negative relationship behaviors and promoted positive relationship behaviors in high school (9th-11th grades), when compared with a standard of care intervention. Dating Matters includes programs for sixth to eighth grade youth and their parents, training for school staff, a youth communications program, and policy and data activities implemented in the community. Self-report survey data were collected from students in 46 middle schools that were randomly assigned to condition within site. Students completed two surveys (fall and spring) in each middle school grade and a single survey in the spring of each high school grade. This study examined self-reported TDV perpetration and victimization, use of negative conflict resolution strategies, and positive relationship skills in the high school follow-up. While varying patterns emerged, latent panel models demonstrated significant program effects for all outcomes. Dating Matters students reported 19% reduced risk for TDV perpetration, 24% reduced risk for TDV victimization, 7% reduced risk for use of negative conflict strategies, and 3% more use of positive relationship skills, on average across time and cohort, than standard of care students. On average, Dating Matters, implemented in middle school, continued to be more effective at reducing TDV perpetration, TDV victimization, and use of negative conflict resolution strategies in high school than an evidence-based comparison program.Trial Registration: clinicaltrials.gov Identifier: NCT01672541.

Youths have experienced disruptions to school and home life since the COVID-19 pandemic began in March 2020. During January-June 2021, CDC conducted the Adolescent Behaviors and Experiences Survey (ABES), an online survey of a probability-based, nationally representative sample of U.S. public- and private-school students in grades 9-12 (N = 7,705). ABES data were used to estimate the prevalence of disruptions and adverse experiences during the pandemic, including parental and personal job loss, homelessness, hunger, emotional or physical abuse by a parent or other adult at home, receipt of telemedicine, and difficulty completing schoolwork. Prevalence estimates are presented for all students and by sex, race and ethnicity, grade, sexual identity, and difficulty completing schoolwork. Since the beginning of the pandemic, more than half of students found it more difficult to complete their schoolwork (66%) and experienced emotional abuse by a parent or other adult in their home (55%). Prevalence of emotional and physical abuse by a parent or other adult in the home was highest among students who identified as gay, lesbian, or bisexual (74% emotional abuse and 20% physical abuse) and those who identified as other or questioning (76% and 13%) compared with students who identified as heterosexual (50% and 10%). Overall, students experienced insecurity via parental job loss (29%), personal job loss (22%), and hunger (24%). Disparities by sex and by race and ethnicity also were noted. Understanding health disparities and student disruptions and adverse experiences as interconnected problems can inform school and community initiatives that promote adolescent health and well-being. With community support to provide coordinated, cross-sector programming, schools can facilitate linkages to services that help students address the adverse experiences that they faced during the ongoing COVID-19 pandemic. Public health and health care professionals, communities, schools, families, and adolescents can use these findings to better understand how students' lives have been affected during the pandemic and what challenges need to be addressed to promote adolescent health and well-being during and after the pandemic.

INTRODUCTION: Although adverse childhood experiences (ACEs) are associated with lifelong health harms, current surveillance data on adults' ACEs exposures are either unavailable or incomplete for many states. In this study, recent data from a nationally representative survey were used to obtain current and complete ACEs estimates at the national and state levels. METHODS: Current, complete, by-state ACEs estimates were obtained by applying small area estimation (SAE) technique to individual-level data on adults aged 18+ years from 2019-2020 Behavioral Risk Factor Surveillance System (BRFSS) survey. The standardized ACEs questions included in 2019-2020 BRFSS survey allowed for obtaining ACEs estimates consistent across states. All missing ACEs responses (state did not offer ACEs questions or offered to only some respondents; respondents skipped questions) were predicted through multilevel mixed-effects logistic (MMEL) and jackknifed MMEL SAE regressions. The analyses were conducted between October 2022 and May 2023. RESULTS: Estimated 62.8% of U.S. adults had past ACEs exposures (range: 54.9% in Connecticut; 72.5% in Maine). Emotional abuse (34.5%) was most common; household member incarceration (10.6%) was least common. Sexual abuse varied markedly between females (22.2%) and males (5.4%). Most ACEs exposures were lowest for adults who were non-Hispanic white, had the highest level of education (college degree) or income (annual income $50,000+), or had access to a personal healthcare provider. CONCLUSIONS: Current complete ACE estimates demonstrate high countrywide exposures and stark socio-demographic inequalities in ACEs burden, highlighting opportunities to prevent ACEs by focusing social, educational, medical, and public health interventions on populations disproportionately impacted.

BACKGROUND: Although preventable, adverse childhood experiences (ACEs) can result in lifelong health harms. Current surveillance data on adults' exposure to ACEs are either unavailable or incomplete for many U.S. states. METHODS: Current estimates of the proportion of U.S. adults with past ACEs exposures were obtained by analysing individual-level data from 2019 to 2020 Behavioural Risk Factor Surveillance System-annual nationally representative survey of noninstitutionalized adults aged 18+years. Standardised questions measuring ACEs exposures (presence of household member with mental illness, substance abuse, or incarceration; parental separation; witnessing intimate partner violence; experiencing physical, emotional, or sexual abuse during childhood) were categorised into 0, 1, 2-3, or 4+ACEs and reported by sociodemographic group in each state. Missing ACEs responses (state did not offer ACEs questions or offered to only some respondents; respondent skipped questions) were modelled through multilevel mixed-effects logistic (MMEL) and jackknifed MMEL regressions. RESULTS: In 2019-2020, an estimated 62.8% of U.S. adults had past exposure to 1+ACEs (range: 54.9% in Connecticut; 72.5% in Maine), including 22.4% of adults who were exposed to 4+ACEs (range: 11.9% in Connecticut; 32.8% in Nevada). At the national and state levels, exposure to 4+ACEs was highest among adults aged 18-34 years, those who did not graduate from high school, or adults who did not have a healthcare provider. Racial/ethnic distribution of adults exposed to 4+ACEs varied by age and state. CONCLUSIONS: ACEs are common but not equally distributed. ACEs exposures estimated by state and sociodemographic group can help decisionmakers focus public health interventions on populations disproportionately impacted in their area.

IMPORTANCE: Adverse childhood experiences (ACEs) are preventable, potentially traumatic events in childhood, such as experiencing abuse or neglect, witnessing violence, or living in a household with substance use disorder, mental health problems, or instability from parental separation or incarceration. Adults who had ACEs have more harmful risk behaviors and worse health outcomes; the economic burden associated with these issues is uncertain. OBJECTIVE: To estimate the economic burden of ACE-associated health conditions among US adults. DESIGN, SETTING, AND PARTICIPANTS: In this economic evaluation, regression models of cross-sectional survey data from the 2019-2020 Behavioral Risk Factor Surveillance System (BRFSS) and previous studies were used to estimate ACE population-attributable fractions (PAFs) (ie, the fraction of total cases associated with a specific exposure) for selected health outcomes (anxiety, arthritis, asthma, cancer, chronic obstructive pulmonary disease, depression, diabetes, heart disease, kidney disease, stroke, and violence) and risk factors (heavy drinking, illicit drug use, overweight and obesity, and smoking) among the 2019 US adult population. Adverse childhood experience PAFs were used to calculate the proportion of total condition-specific medical spending and lost healthy life-years related to ACEs using Global Burden of Disease Study data. Data analysis was performed from September 10, 2021, to November 29, 2022. EXPOSURE: Adverse childhood experiences (age <18 years). MAIN OUTCOMES AND MEASURES: Monetary valuation of ACE-associated morbidity and mortality using standard US value of statistical life methods and presented in terms of annual and lifetime per affected person and total population estimates at the national and state levels. RESULTS: A total of 820 673 adults, representing 255 million individuals, participated in the BRFSS in 2019 and 2020. An estimated 160 million of the total 255 million US adult population (63%) had 1 or more ACE, associated with an annual economic burden of $14.1 trillion ($183 billion in direct medical spending and $13.9 trillion in lost healthy life-years). This was $88 000 per affected adult annually and $2.4 million over their lifetimes. The lifetime economic burden per affected adult was lowest in North Dakota ($1.3 million) and highest in Arkansas ($4.3 million). Twenty-two percent of adults had 4 or more ACEs and comprised 58% of the total economic burden-the estimated per person lifetime economic burden for those adults was $4.0 million. CONCLUSIONS AND RELEVANCE: In this cross-sectional analysis of the US adult population, the economic burden of ACE-related health conditions was substantial. The findings suggest that measuring the economic burden of ACEs can support decision-making about investing in strategies to improve population health.

This study describes rates of violence victimization, perpetration, and witnessing in 6th-11th grade for a multisite sample (N = 3,466) of predominantly Black and Hispanic middle- and high-school students from urban areas with high rates of crime and economic disadvantage. Students completed surveys in middle and high school assessing teen dating violence, stalking, sexual violence and harassment, bullying, cyberbullying, and physical violence perpetration and victimization, as well as witnessing violence. The highest prevalence rates are observed most often in 8th or 9th grade. Youth reported high rates of witnessing serious assault and severe community violence throughout adolescence. These findings suggest that efforts to prevent violence among youth living in under-resourced communities need to start early and address community-level socioeconomic disparities.

BACKGROUND: Multiple adverse childhood experiences (ACEs) are associated with poor sexual and mental health outcomes in low- and middle-income countries (LMICs). Less well understood is how discrete and gendered clustering of ACEs may influence health. OBJECTIVE: To assess how multiple ACEs co-occur and how dominant patterns of co-occurrence are associated with mental distress, substance use, and sexual risk behaviors among young women and men in Sub-Saharan Africa. PARTICIPANTS AND SETTING: We used pooled data of young men and women aged 19-24 from comparable, nationally representative Violence Against Children and Youth Surveys (VACS) conducted in Cote d'Ivoire, Kenya, Lesotho, Mozambique, and Namibia (n(f) = 7183; n(m) = 2207). METHODS: We estimated sex-disaggregated latent classes of six ACEs among young women and men. We ran Bolck-Croon-Hagenaars (BCH) distal outcome analysis to test the sex-stratified relationships between ACEs latent classes and health outcomes. RESULTS: A six class solution best fit the female data. Classes included witnessing violence and experiencing physical violence (PV); experiencing PV; high ACEs; witnessing community violence; orphanhood; and low ACEs exposure. Among males, the best-fitting three-class solution included experiencing PV and witnessing community violence; high ACEs; and low ACEs exposure. Membership in the high ACEs class was associated with mental distress among females and males, and substance use among males. No differences in sexual risk behavior were identified by class membership among either females or males. CONCLUSIONS: Discrete clusters of co-occurring ACEs are associated with elevated odds of mental distress among females, and mental distress and substance use among males. Preventing ACEs may improve mental health among young women and men in LMICs in Sub-Saharan Africa.

Adverse childhood experiences (ACEs) are defined as preventable, potentially traumatic events that occur among persons aged <18 years and are associated with numerous negative outcomes; data from 25 states indicate that ACEs are common among U.S. adults (1). Disparities in ACEs are often attributable to social and economic environments in which some families live (2,3). Understanding the prevalence of ACEs, stratified by sociodemographic characteristics, is essential to addressing and preventing ACEs and eliminating disparities, but population-level ACEs data collection has been sporadic (1). Using 2011-2020 Behavioral Risk Factor Surveillance System (BRFSS) data, CDC provides estimates of ACEs prevalence among U.S. adults in all 50 states and the District of Columbia, and by key sociodemographic characteristics. Overall, 63.9% of U.S. adults reported at least one ACE; 17.3% reported four or more ACEs. Experiencing four or more ACEs was most common among females (19.2%), adults aged 25-34 years (25.2%), non-Hispanic American Indian or Alaska Native (AI/AN) adults (32.4%), non-Hispanic multiracial adults (31.5%), adults with less than a high school education (20.5%), and those who were unemployed (25.8%) or unable to work (28.8%). Prevalence of experiencing four or more ACEs varied substantially across jurisdictions, from 11.9% (New Jersey) to 22.7% (Oregon). Patterns in prevalence of individual and total number of ACEs varied by jurisdiction and sociodemographic characteristics, reinforcing the importance of jurisdiction and local collection of ACEs data to guide targeted prevention and decrease inequities. CDC has released prevention resources, including Preventing Adverse Childhood Experiences: Leveraging the Best Available Evidence, to help provide jurisdictions and communities with the best available strategies to prevent violence and other ACEs, including guidance on how to implement those strategies for maximum impact (4-6).

The COVID-19 pandemic created an environment of disruption and adversity for many adolescents. We sought to establish the prevalence of non-dating sexual violence, sexual dating violence, and physical dating violence victimization among adolescents during the COVID-19 pandemic and to investigate whether experiences of disruption and adversity placed adolescents at greater risk for these forms of interpersonal violence. We conducted a secondary analysis of data from the Adolescent Behavior and Experiences Survey, collected January to June 2021 from a nationally representative sample of U.S. high school students (N = 7,705). Exposures included abuse by a parent; economic, housing, and food and nutrition insecurity; interpersonal connectedness; and personal well-being. Among female students, 8.0% experienced non-dating sexual violence; 12.5% experienced sexual dating violence; and 7.7% experienced physical dating violence. Among male students, 2.2% experienced non-dating sexual violence; 2.4% experienced sexual dating violence; and 4.9% experienced physical dating violence. Among female students, both emotional and physical abuse by a parent was related to non-dating sexual violence, emotional abuse was related to sexual dating violence, and physical abuse was related to physical dating violence. Among males, emotional abuse by a parent was related to physical dating violence and physical abuse by a parent was related to sexual dating violence. Hunger was associated with sexual and physical dating violence among female students and homeless was associated with physical dating violence among male students. Although there were differences by sex, abuse by a parent, hunger, and homelessness created precarity that may have increased the likelihood that adolescents would be exposed to risky peer or dating relationships. Adolescents need support that stops and prevents experiences of non-dating sexual and dating violence connected to interventions that address adversities experienced during the COVID-19 pandemic.

Adverse and positive childhood experiences have a profound impact on lifespan health and well-being. However, their incorporation into ongoing population-based surveillance systems has been limited. This paper outlines critical steps in building a comprehensive approach to adverse and positive childhood experiences surveillance, provides examples from the Preventing Adverse Childhood Experiences: Data to Action cooperative agreement, and describes improvements needed to optimize surveillance data for action. Components of a comprehensive approach to adverse and positive childhood experiences surveillance include revisiting definitions and measurement, including generating and using uniform definitions for adverse and positive childhood experiences across data collection efforts; conducting youth-based surveillance of adverse and positive childhood experiences; using innovative methods to gather and analyze near real-time data; leveraging available data, including from administrative sources; and integrating data on community- and societal-level risk and protective factors for adverse childhood experiences, including social and health inequities such as racism and poverty, as well as policies and conditions that create healthy environments for children and families. Comprehensive surveillance data on adverse and positive childhood experiences can inform data-driven prevention and intervention efforts, including focusing prevention programming and services to populations in greatest need. Data can be used to evaluate progress in reducing the occurrence of adverse childhood experiences and bolstering the occurrence of positive childhood experiences. Through expansion and improvement in adverse and positive childhood experiences surveillance-including at federal, state, territorial, tribal, and local levels-data-driven action can reduce children's exposure to violence and other adversities and improve lifelong health and well-being.

Lifelong health and well-being are rooted in developmental experiences faced during childhood.1 Adverse childhood experiences (ACEs) are preventable, potentially traumatic events that occur in childhood (age 017 years) such as witnessing or experiencing violence, experiencing neglect, or having a family member attempt or die by suicide. Exposure to ACEs is linked to negative outcomes later in life, including chronic disease; mental health and substance use problems; and even lower education attainment, fewer job opportunities, and decreased earning potential.1, 2, 3, 4, 5 More than 60% of adults report experiencing 1 ACE during childhood, and nearly 1 in 6 adults report experiencing 4 ACEs.6 Recent research suggests that preventing ACEs could potentially reduce millions of cases of heart disease, depression, and other negative health outcomes.6 Given the prevalence of ACEs, their documented impacts on future health and social outcomes, and the potential impacts of prevention efforts, investments in ACE prevention may help to improve public health across the lifespan.

INTRODUCTION: Intimate partner violence and sexual violence are widespread and often occur early in life. This systematic review examines the effectiveness of interventions for primary prevention of intimate partner violence and sexual violence among youth. METHODS: Studies were identified from 2 previous systematic reviews and an updated search (January 2012-June 2016). Included studies were implemented among youth, conducted in high-income countries, and aimed to prevent or reduce the perpetration of intimate partner violence or sexual violence. In 2016-2017, Guide to Community Preventive Services (Community Guide) methods were used to assess effectiveness as determined by perpetration, victimization, or bystander action. When heterogeneity of outcomes prevented usual Community Guide methods, the team systematically applied criteria for favorability (statistically significant at p<0.05 or approaching significance at p<0.10) and consistency (75% of results in the same direction). RESULTS: A total of 28 studies (32 arms) met inclusion and quality of execution criteria. Interventions used combinations of teaching healthy relationship skills, promoting social norms to protect against violence, or creating protective environments. Overall, 18 of 24 study arms reported favorable results on the basis of the direction of effect for decreasing perpetration; however, favorability for bystander action diminished with longer follow-up. Interventions did not demonstrate consistent results for decreasing victimization. A bridge search conducted during Fall 2020 confirmed these results. DISCUSSION: Interventions for the primary prevention of intimate partner violence and sexual violence are effective in reducing perpetration. Increasing bystander action may require additional follow-up as effectiveness diminishes over time. Findings may inform researchers, school personnel, public health, and other decision makers about effective strategies to prevent intimate partner violence and sexual violence among youth.

INTRODUCTION: Alternative measurement approaches for adverse childhood experiences (i.e., count score versus individual adverse childhood experiences measured dichotomously versus individual adverse childhood experiences measured ordinally) can alter the association between adverse childhood experiences and adverse outcomes. This could significantly impact the interpretation of adverse childhood experiences research. METHODS: Data were collected in 2018 (analyzed in 2020) via Amazon's Mechanical Turk and from people incarcerated in 4 correctional facilities (N=1,451). Included adverse childhood experience questions measured the following: physical, emotional, and sexual abuse; physical and emotional neglect; household mental illness, substance use, domestic violence, and incarceration; and exposure to community violence before age 18 years. A total of 19 measured outcomes spanned 4 domains of functioning: general functioning, substance use, psychopathology, and criminal behavior. RESULTS: Regression models using the count score explained the least amount of variance in outcomes, whereas multivariable regression models assessing adverse childhood experiences on a continuum explained the most variance. In many instances, the explained variance increased by 2-5 times across the predictive models. When comparing regression coefficients for multivariable regression models that measured adverse childhood experiences as binary versus ordinal, there were notable differences in the effect sizes and in which adverse childhood experiences predicted outcomes. Disparities in results were most pronounced among high-risk populations that experience a disproportionate amount of adverse childhood experiences. CONCLUSIONS: Alternative methods of measuring adverse childhood experiences can influence understanding of their true impact. These findings suggest that the deleterious effects of imprecise measurement methods may be most pronounced in the populations most at risk of adverse childhood experiences. For the sake of prevention, the measurement of adverse childhood experiences must evolve.

Dating Matters(®) is a CDC-developed comprehensive, multi-component teen dating violence (TDV) prevention model, made available to the public in 2019. A longitudinal, multi-site demonstration project found that the model significantly reduced TDV during middle school relative to an evidence-based, single-program intervention (Safe Dates; Niolon et al., 2019), when implemented across 46 middle schools in four high-risk urban areas with predominantly Black (55%) and Hispanic (28%) youth participants. Research on the costs of implementing TDV prevention strategies is limited, despite recognition within the field of prevention science that such data are critical to widespread dissemination. The current study adds to the available literature on the cost of dating violence prevention by estimating the budgetary impact from the payer perspective of implementing the comprehensive Dating Matters model, compared to Safe Dates, at four sites over four school years to inform prevention planning in communities. Total costs of implementing Dating Matters were relatively stable within sites over time but varied greatly between sites (M = $175,452 per year; range = $130,149 to $227,604). The mean per-student cost of Dating Matters was $145.40 but also ranged widely ($20.66 to $324.65) across sites and years. Variation was largely driven by staffing costs and number of students served. As expected, total and per-student costs were substantially lower at all sites for the Safe Dates program (M = $12,148; range = $2,848 to $17,840; $44.81 per student) compared to Dating Matters. This study provides an estimate from the payer perspective to demonstrate the budgetary impact of Dating Matters. These estimates can help inform implementation decisions and planning by potential funders, communities, and organizations as they seek to support and implement effective TDV prevention strategies. It also adds substantially to understanding of the additional costs associated with a move from single-program interventions to community-wide initiatives.

Teen dating violence (TDV) affects millions of young people in the USA each year (Basile et al. 2020) and is associated with a myriad of negative consequences across the lifespan, including placing individuals at greater risk for experiencing intimate partner violence (IPV) in their more permanent relationships in adulthood (Exner-Cortens et al. Pediatrics 131(1):71-78 Exner-Cortens et al. 2013; Exner-Cortens et al. Journal of Adolescent Health 60(2):176-183 Exner-Cortens et al. 2017). The CDC developed the Dating Matters®: Strategies to Promote Healthy Teen Relationships comprehensive prevention model to prevent TDV and its consequences among young people, and it was found to be effective at reducing TDV perpetration and victimization compared with another evidence-based program (Niolon et al. American Journal of Preventive Medicine 57(1):13-23 Niolon et al. 2019). Dating Matters addresses multiple risk and protective factors for TDV through its multiple components, many of which are shared risk and protective factors for other forms of violence and risk behaviors among adolescents. This article introduces this special section, which includes three papers examining these secondary outcomes of the Dating Matters comparative effectiveness, multi-site, longitudinal cluster randomized controlled trial and concludes with an invited commentary by Debman and Temple (in press). This introduction briefly discusses the Dating Matters comprehensive prevention model, the comparative effectiveness trial used to evaluate effectiveness, the outcomes examined by the three papers included in this special section and the commentary from external reviewers. This special section makes an important contribution to the field of violence prevention, highlighting a preventive intervention for TDV that addresses a constellation of risk and protective factors and demonstrating its effects on multiple adolescent risk and violence outcomes.

Sexual violence (SV), including sexual harassment (SH), is a significant public health problem affecting adolescent health and well-being. This study extends prior research by evaluating the effectiveness of a comprehensive teen dating violence prevention model, Dating Matters, on SV and SH perpetration and victimization, inclusive of any victim-perpetrator relationship, among middle school students. Dating Matters includes classroom-delivered programs for youth in 6th, 7th, and 8th grades; community-based programs for parents; a youth communications program; training for educators; and community-level activities. Middle schools in four urban areas in the USA were randomly assigned to receive Dating Matters (DM, N = 22) or a standard-of-care intervention (SC, N = 24) over four consecutive school years (2012-2016). The analytic sample included two cohorts who entered the study in 6th grade and completed 8th grade by the end of the study allowing for full exposure to Dating Matters (DM: N = 1662; SC: N = 1639; 53% female; 50% black, non-Hispanic; 6 waves of data collection for each cohort). Structural equation modeling was employed with multiple imputation to account for missing data. Dating Matters was associated with significant reductions in SV and SH perpetration and victimization scores in most-but not all-sex/cohort groups by the end of 8th grade relative to an evidence-based TDV prevention program. On average, students receiving Dating Matters scored 6% lower on SV perpetration, 3% lower on SV victimization, 4% lower on SH perpetration, and 8% lower on SH victimization by the end of middle school than students receiving an evidence-based violence prevention program. Overall, Dating Matters shows promise for reducing SV and SH, occurring both within and outside dating relationships, through middle school. Clinicaltrials.gov Identifier: NCT01672541.

Teen dating violence (TDV) is associated with a variety of delinquent behaviors, such as theft, and health- and delinquency-related risk behaviors, including alcohol use, substance abuse, and weapon carrying. These behaviors may co-occur due to shared risk factors. Thus, comprehensive TDV-focused prevention programs may also impact these other risk behaviors. This study examined the effectiveness of CDC's Dating Matters(R): Strategies to Promote Healthy Teen Relationships (Dating Matters) comprehensive TDV prevention model compared to a standard-of-care condition on health- and delinquency-related risk behaviors among middle school students. Students (N = 3301; 53% female; 50% black, non-Hispanic; and 31% Hispanic) in 46 middle schools in four sites across the USA were surveyed twice yearly in 6th, 7th, and 8th grades. A structural equation modeling framework with multiple imputation to account for missing data was utilized. On average over time, students receiving Dating Matters scored 9% lower on a measure of weapon carrying, 9% lower on a measure of alcohol and substance abuse, and 8% lower on a measure of delinquency by the end of middle school than students receiving an evidence-based standard-of-care TDV prevention program. Dating Matters demonstrated protective effects for most groups of students through the end of middle school. These results suggest that this comprehensive model is successful at preventing risk behaviors associated with TDV. clinicaltrials.gov Identifier: NCT01672541.

Few comprehensive primary prevention approaches for youth have been evaluated for effects on multiple types of violence. Dating Matters(R): Strategies to Promote Healthy Teen Relationships (Dating Matters) is a comprehensive teen dating violence (TDV) prevention model designed by the Centers for Disease Control and Prevention and evaluated using a longitudinal stratified cluster-randomized controlled trial to determine effectiveness for preventing TDV and promoting healthy relationship behaviors among middle school students. In this study, we examine the prevention effects on secondary outcomes, including victimization and perpetration of physical violence, bullying, and cyberbullying. This study examined the effectiveness of Dating Matters compared to a standard-of-care TDV prevention program in 46 middle schools in four high-risk urban communities across the USA. The analytic sample (N = 3301; 53% female; 50% Black, non-Hispanic; and 31% Hispanic) consisted of 6th-8th grade students who had an opportunity for exposure to Dating Matters in all three grades or the standard-of-care in 8th grade only. Results demonstrated that both male and female students attending schools implementing Dating Matters reported 11% less bullying perpetration and 11% less physical violence perpetration than students in comparison schools. Female Dating Matters students reported 9% less cyberbullying victimization and 10% less cyberbullying perpetration relative to the standard-of-care. When compared to an existing evidence-based intervention for TDV, Dating Matters demonstrated protective effects on physical violence, bullying, and cyberbullying for most groups of students. The Dating Matters comprehensive prevention model holds promise for reducing multiple forms of violence among middle school-aged youth. ClinicalTrials.gov Identifier: NCT01672541.

As evidence-based interventions (EBIs) to prevent mental, emotional, and behavioral health problems continue to become available, approaches for implementation in systems and settings, at scale, are needed. The article, Scaling-up Evidence-based Interventions in U.S. Public Systems to Prevent Behavioral Health Problems: Challenges and Opportunities (Fagan et al. 2019) examines five large, complex public systems (behavioral health, child welfare, education, juvenile justice, and public health) that have adopted and implemented EBIs in various ways and presents common factors that support scale-up in these systems. This commentary builds on the authors' strategic approach to offer a few additional considerations-issues of sustainability, ways of thinking about knowledge creation, and use of systems science/modeling approaches-to address scale-up in public systems. Moreover, the focus on public systems provides an opportunity to consider how the implementation and sustainment of EBIs might more directly address social determinants of health that are relevant across policy areas and public systems.

Intimate partner violence (IPV) and sexual violence (SV) are preventable public health problems affecting millions in the United States. The Community Preventive Services Task Force (CPSTF), an independent panel of experts that develops evidence-based recommendations based on rigorous systematic reviews, recommends interventions that aim to prevent or reduce IPV and SV among youth aged 12-24 years. Decision makers can use these findings to select interventions appropriate for their populations, identify additional areas for research, and justify funding requests.
