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.
