Seattle Pediatric Concussion Research Collaborative


At the Seattle Pediatric Concussion Research Collaborative, we are pursuing research to help reduce the incidence and consequences of concussion among children and adolescents. Our efforts include the following studies and projects. If you are interested in learning more, please contact Dr. Fred Rivara.

Help us answer questions about childhood health and illness, and help other children in the future. Learn more.


Four Corners Youth Concussion Registry

The goal of this study is to describe the natural history of concussion recovery in youth and how it may be vary by age, gender and cause of injury.

One Team

The goal of this study is to partner with community-based sports leagues to develop and deploy a pre-game activity that fosters sportsmanship and reduces risk of concussion.

Collaborative Care Model for Treatment of Persistent Symptoms After Concussion Among Youth (Collaborative Care Study)

The primary goal of this study is to determine the effectiveness of a stepped-collaborative care intervention model in reducing post-concussive and co-occurring mental health symptoms in adolescents with persistent post-concussive symptoms. (PIs: Rivara, McCarty, Zatzick)

Building community to address disparities in concussion care of Hispanic youth

The goals of this project is to identify barriers and facilitators to concussion care seeking by Hispanic youth athletes and then develop and evaluate Spanish-language concussion education materials to address knowledge deficits and barriers to care. (PI: Kroshus)

Bystander Training Project

The goal of this project is to develop, pilot, and evaluate efficacy of a bystander training program that encourages youth athletes to encourage concussion help seeking by teammates. (PI: Kroshus)

PAC-12 Coach Education Project

The goal of this project is to develop, pilot, and evaluate efficacy of a concussion education program for PAC-12 coaches (PI: Kroshus)

Concussion and Injury Surveillance (CIS) in Youth Football Players

The goal of this study is to work with the Northwest Junior Football League (NJFL) and study how young athletes involved in football recover after concussion. (PI: Rivara)

Theory Development Related to Concussion Safety Behaviors of High School Coaches

This study’s goal is to identify knowledge gaps among high school coaches and to build a comprehensive theory of the factors driving their concussion prevention, identification and management behaviors. The study’s results will be used to inform the design of concussion education for coaches. (PI: Kroshus)


Care for Persistent Concussive Symptoms (CARE4PCS) Study

CARE4PCS was a pilot study that evaluated an innovative, collaborative care model for treating 11-to-17-year-olds who have persistent concussion symptoms. This model brings together providers with different specialties. We are evaluating whether collaborative care is feasible and effective for these patients, and investigating whether we can predict how future patients might respond to similar treatment. (PI: Rivara)

MRI imaging in pediatric concussion: a retrospective analysis

Characterize the rate of positive findings in post-acute MRI related to sport concussion. Describe the cost and health outcomes associated with the majority of found features reflecting non-specific (non-concussion) abnormalities. (PI: Friedman)

Sub-Threshold Exercise Program (STEP) – chart review

The goal of this study is to examine the effectiveness and safety of the STEP program using clinical data in an open-label fashion. (PI: Rivara)

Auditing access to outpatient rehabilitation services for children with traumatic brain injury and public insurance in Washington State

The goal of this study was to identify insurance-based disparities in access to outpatient pediatric neurorehabilitation services for children with traumatic brain injury. We found Therapy clinics were less likely to accept public versus private insurance. Therapy clinics accepting public insurance had longer wait times than clinics that accepted only private insurance. (PI: Fuentes)

Return to Learn (RTL) After Concussion Summit

This summit’s goal is to bring together an expert group of stakeholders to discuss unmet needs of students returning to learn after concussion and to help develop statewide guidelines. (PI: Vavilala)

Weekend Soccer Tournament (WEST) Study

This study’s goal is to improve our understanding of the relationship between head impact acceleration (HIA) – how fast the head is moving and rotating when it makes impact – and potential changes in concussion symptoms, brain function and brain structure (PI: Rivara)

Soccer Player Head Impact Acceleration (SOPHIA) Study

The SOPHIA study measures HIA’s magnitude and how often it occurs among a group of middle school soccer players. Our researchers will compare HIA among the group’s male and female players to see if it differs between genders. (PI: Chrisman)

Parents of Youth Soccer Players: Knowledge, Attitudes, Communication

This study’s goals are to understand what parents of youth soccer players believe are the risks of concussion and how they act (e.g., communicate, advocate) with respect to concussion prevention, identification and management. (PI: Kroshus)

School SES, Athletic Trainers and Concussion Identification

The goal of this study is to determine how athletic trainer staffing is patterned by school socioeconomic status. (PI: Kroshus)

Agreement Between Parents and Athletes in Reporting Number of Plays and Concussion Symptoms

This study will investigate how parent reports of sports-related concussion among youth compare to how the athlete self-reports those concussions. Better understanding the level of agreement between parents and athletes in reporting the number of games and practices the child participates in, as well as type and severity of symptoms, will help researchers design studies that capture how often concussions occur. (PI: Rivara)

Longitudinal Imaging of Pediatric Concussion (IMAGE)

The goal of this study is to develop a repository of MR imaging data in youth concussion. We will be observing changes in the brain after concussion though MRI imaging and neurocognitive testing. (PI: MacDonald)

Study of an Exercise Program (STEP) for Concussion

The goal of this study is to evaluate the efficacy of a sub-threshold exercise program for decreasing persistent concussive symptoms and explore potential benefits. (PI: Chrisman)

Concussion and Driving Skills in the Young Driver Study

The goal of this study is to explore the cognitive impact of recent concussion on teen and young adult driving performance in a simulated driving environment. (PI: Ebel)
