Although we know a lot about returning to sports, exercise, and school after concussion, we know very little about returning to drive after a concussion. Our Driving after Concussion study needs the help of both healthy and recently concussed teen partners in our research to understand how concussion affects driving behaviors in teens.We are looking for healthy (have not had a concussion in the last year) and recently concussed teens who are 16.5-18 years old with a drivers license and their own smartphone.Our teen research partners may be asked to complete surveys about themselves and download smartphone applications that track symptoms associated with concussion and/or observe real-world driving behaviors. They may also be asked to come to CHOP's Driving Simulator Lab to complete a 3-hour session that includes surveys, clinical testing, and device testing along with a simulated driving assessment to observe driving behavior.All teens who participate will be compensated for their time and effort.

The Center for Injury Research & Prevention is seeking teens age 16-19 and a parent to participate in a research study about distracted driving. Both teens and parents must be licensed drivers and use smartphones. The purpose of this research study is to figure out if a new smartphone app impacts distracted driving, and to learn parent and teen perspectives on the app. Participants will be asked to complete occasional surveys and use a smartphone app for up to 3 weeks. The entire study can be completed remotely, and no visits to CHOP are required. Families are compensated for their time in the study.

Researchers at CHOP are trying to improve outcomes in the treatment of adolescents with anorexia nervosa. Eligible families will receive Family Based Treatment for anorexia nervosa. Some adolescents with anorexia nervosa will also receive Cognitive Remediation Therapy (a treatment that increases flexible thinking). Both parents are required to participate and any siblings living at home are asked to come to the first four treatment sessions. Families will receive treatment for approximately 6 months and will be asked to complete number of assessments during treatment and at two time points after treatment ends.

The Childrens Hospital of Philadelphia is seekinghealthy adolescents between the ages of 12-13, who are currently in the 7^thgrade,to participate in the Sleep and Growth Study 2. The purpose of this research is to learn more about the changes in sleep and body size in adolescents as they transition from middle to high school. Participants will be asked to visit CHOP so that we can measure their bone density. Following this visit, participants will wear a sleep tracker over a 2-week period and speak to a team member by phone on three occasions about the types of food eaten in the previous 24 hours. If you and your child agree to participate, the study will involve 3 visits over approximately 2 years. All participants are compensated for their time and effort.For more information and study details, please call 215-590-2383, ext. 1, or emails_grow@chop.edu.
