Additional Study Information: Anorexia Nervosa is a serious illness and relapse rates are high. We have shown that behavioral routines get stuck/entrenched. Our newest research, Relapse Prevention and Changing Habits (REACH+) for Anorexia Nervosa, aims to help patients minimize unhelpful routines and develop more healthful recovery-oriented behavior. Participants will complete initial treatment on our inpatient eating disorders unit at the New York State Psychiatric Institute; this treatment is provided at no cost. Following weight restoration, interested participants will meet with clinicians via secured Telehealth platform for an outpatient study intervention for about 6 months to work on changing illness behaviors, maintaining healthy eating, and maintaining a healthy weight after leaving the hospital. This study aims to evaluate this new outpatient intervention. To be eligible for this study, participants must be 18-60 years old, have a diagnosis of Anorexia Nervosa or, if not formally diagnosed, believe they may meet criteria.
