Trends in ACEs

 in the US

Overall, there appear to have been more historical and recent improvements in adverse childhood experiences (ACEs) than deteriorations in the 20th and 21st centuries.


Exposure to Multiple Forms of Bias Victimization on Youth and Young Adults: Relationships with Trauma Symptomatology and Social Support

This paper explores relationships between exposure to multiple types of bias-motivated victimization, trauma symptomatology and perceived social support in the context of a broader adversity history.

This article reviews Internet safety education initiatives and makes the case that their goals would be better accomplished by building on the foundation and experience of the more evidence-based educational programs currently addressing related forms of offline risk, rather than as stand-alone efforts.

Strengthening the predictive power of screening for adverse childhood experiences (ACEs) in younger and older children

This study derives 2 new modified ACE inventories for 2-9-year-olds and 10-17-year-olds that outperform the original ACE in predicting trauma symptoms.

Current Projects

Trends and New Directions in the Law Enforcement Response to the Sex Trafficking of Minors: A Nationally Representative Study (LEA-CST)

Funded by: The National Institute of Justice, award 2020-MU-CX-0041. The overall goal of the LEA-CST Study is to assess and document the extent that law enforcement has been changing practices to child sex trafficking investigations from a delinquency-oriented response to a victim-centered approach.


The Fourth National Survey of Internet & Technology Facilitated Child Exploitation (N-JOV4)

Funded by: The National Institution of Justice, award 2020-MU-CX-K002. The overall goals of the Fourth National Juvenile Online Victimization Survey (N-JOV4) are to protect children against online dangers by developing a better understanding of new threats, problems, and concerns encountered by law enforcement in its effort to protect children in the changing technological environment; tracking and monitoring new and continuing threats; and identifying which investigative strategies are associated with more favorable outcomes in protecting children.

Hate Crime Investigations and Offender Profiles: A National Survey of U.S. Law Enforcement Agencies (HC-LEA)

Funded by: National Institute of Justice, award 2018-MU-MU-0029.  This study aims to provide the public with better information about hate crimes, help inform policy and procedural recommendations, improve national data collection strategies, and improve law enforcement training protocols.

Methodological Research to Support the National Survey of Children’s Exposure to Violence (NatSCEV)

Funded by: Bureau of Justice Statistics and Office of Juvenile Justice Delinquency Prevention. This project is intended to review the methods and instruments used in the National Survey of Children’s Exposure to Violence (NatSCEV) and make recommendations for its improvement.

National Incidence Studies of Missing, Abducted, Runaway and Throwaway Children (NISMART-4)

Funded by: Office of Juvenile Justice and Delinquency and Prevention.  U.S. Department of Justice, award 2017-MC-FX-K011. The principal goal of NISMART is to design and test data collection methodologies that result in accurate national statistics on the number and characteristics of missing children reported to law enforcement.

A Study of Trauma and Resiliency among Forensic Examiners Investigating Child Pornography

Funded by: The National Institution of Justice, award 2019-R2-CX-0034 The present study seeks to understand the impact and management of stress, burnout, and vicarious trauma in order to advance resiliency among forensic scientists and police investigators who investigate cases involving child sexual abuse material.

News and Briefs

What schools can do to reduce the risk that teachers and other educators will sexually abuse children

Some suggestions for preventing sexual abuse in school environments.

How universal childhood trauma screenings could backfire

A universal screening system requires a lot of testing and planning to work out the bugs and rigorous clinical evaluation to make sure that it provides more benefit than harm. Let’s not ruin a good idea by setting up an expensive and time-consuming universal system before we know how to make it work.

Commentary: Ills of spanking emerge: Studies suggest it's risky to use corporal punishment

The American Academy of Pediatrics has new guidelines to counsel parents against the use of spanking. This editorial outlines some of the thinking behind that advice.

Sexual assault among adolescents: 6 facts

Some important underappreciated facts about the prevalence of sexual assault among adolescents, its under-reporting, and the availability of evidence-based educational programs to reduce its frequency.

My Turn: The path to preventing teacher sexual abuse

The St. Paul's School report on teacher sexual misconduct is a sign of progress. We can do a much better job at preventing misconduct once schools become willing to raise the profile of this uncomfortable topic and admit the vulnerability endemic to the teaching environment.

Op-Ed (The Conversation) How sexual partner abuse has changed with social media

In a large study the CCRC recently did on sexual partner abuse and social media, we found that sextortion mostly involves the classic dynamics of abusive relationships, or malicious online seducers with a few digital-age twists. The dynamics are offensive and manipulative, to be sure, but also sadly familiar. Similar dynamics have been seen in CCRC research about sexting and other internet-related sex crimes.

Op-Ed (Washington Post): Banning apps won’t protect kids from predators. They’re in danger offline, too.

Lovell’s horrific case stokes our fear of a misleading archetype: the stranger abductor/molester/killer. After waning over time, this fear has grown, thanks to the notion that the Internet gives strangers access to our children on an order previously unseen. But this particular anxiety actually threatens to divert us from important strides we’ve made over the last generation in understanding how to bolster children’s safety. We need to keep in mind the atypical features of this type of crime.

Op-Ed (Concord Monitor): ‘Bystanders’ are key to preventing sexual assault

A new generation of programs for adolescents, such as “Coaching Boys Into Men,” “Green Dot” and “Shifting Boundaries,” target “bystanders” rather than potential perpetrators or victims of sexual assault. These programs are proving to be effective at reducing rates of sexual assault and other forms of violence and increasing support for victims.
