Dr. Colleen C. Schreyer is an Assistant Professor in the Department of Psychiatry and Behavioral Sciences at the Johns Hopkins School of Medicine and the Director of Clinical Research for the Johns Hopkins Eating Disorders program. Her research interests include the roles of anxiety and decision-making in the maintenance of anorexia nervosa and bulimia nervosa, the use of exposure and response prevention in the treatment of anorexia nervosa, and identifying psychosocial predictors of eating disorder treatment response. Dr. Schreyer also provides individual and family therapy for adults and adolescents diagnosed with eating disorders and conducts pre-surgical psychiatric evaluations for bariatric surgery candidates. Within obesity, Dr. Schreyer’s research is focused on the efficacy of behavioral and surgical weight loss treatment, inpatient treatment for post-bariatric surgery patients who develop eating disorders, and psychosocial predictors of bariatric surgery outcomes including sleep and pain catastrophizing.
