We are looking for adolescents who have a current diagnosis of anorexia nervosa or other specified feeding and eating disorder and one parent to participate in a study to help us understand higher order thinking differences in teens with eating disorders. We are also looking for adolescents who do not have an eating disorder. The purpose of this study is to look for associations between higher order thinking and eating disorders. These findings may help us understand the impact of eating disorders on thinking skills.

This study wants to know about the problems that Black or African American teenagers with type 1 diabetes (T1D) and their families face. It also wants to see how these problems affect their feelings, behavior, and how they get along with others. The study will find out how well they can handle T1D and adapt to it. It will also learn how good things like being strong, family, and where they live might help young people who have to deal with hard things. This includes how well they handle their feelings, behavior, relationships, and T1D care.

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 purpose of this study is to evaluate social interactions in adolescents and whether changes in information can influence social behaviors. This study will focus on behavioral assessments of social processing over time in adolescents. The information collected in this study is essential for developing clinical treatments focused on addressing social processes in adolescents with restrictive eating disorders and to improve our understanding of social processing in adolescents with restrictive eating disorders, informing both future research and clinical care.
