Other Specified Feeding or Eating Disorder

The goal of this study is to develop and test a digital program to help people with eating disorders in their everyday lives. The program uses brief surveys and sensor data collected by smartphones to understand when someone may be at higher risk for behaviors like restricting food, binge eating, or using unhealthy weight control behaviors.

Social processing and cognition are often altered in patients with eating disorders. The goal of this clinical trial is to assess two different social therapeutic interventions -- one educational, one interactive -- for their effectiveness in improving clinical outcomes in patients with eating disorders. Patients in both interventions will receive education about social function in eating disorders, but those in the interactive treatment group will complete an additional collaborative art task. Participants will: * attend a baseline study visit to complete clinical interviews, cognitive testing, and behavioral tasks * complete a pre-intervention assessment with questionnaires * attend eight sessions of their assigned treatment group over the course of 12 weeks * complete three virtual follow-up assessments 4, 8, and 12 months from their baseline * attend a final study visit to repeat some clinical interviews, cognitive testing, and behavioral tasks Researchers will compare changes in eating disorder, mood, and anxiety symptoms as well as test results from baseline and final study visits for each group to see if * patients can be treated effectively with education alone or if an interactive group component produces additional benefits * cognitive and behavioral task performance are associated with recovery or illness state.

The goal of this observational longitudinal study is to investigate characteristics and factors associated with the development of Severe and Enduring Eating Disorders (SEED). In this project, the researchers will follow two prospective cohorts of patients with eating disorders (ED), one adolescent (ages 14-17) and one adult (ages 18+), in terms of change in and impact of clinical, psychological, and biological risk factors. Data will be collected at baseline, after treatment, two years after baseline, and thereafter five, 10 and 20 years after baseline. Participants will be asked to undergo a physical examination, leave blood samples, be interviewed, and fill in questionnaires. If the participants are minors, their care takers will also fill in the questionnaires. The study aims to explore how clinical, psychological, and biological risk factors-including comorbidity, personality characteristics, difficulties with emotion regulation (ER), cognitive inflexibility, loneliness, severe ED symptoms, and inflammatory activation-contribute to a chronic course of the disorder.

The aim of this study is to investigate the efficacy, efficiency, and patient experience of a new intervention program on adolescents with high-complexity eating disorders (ED). A prospective group of adolescents with ED (N=60) will follow this treatment program including four different phases: 1) Inpatient treatment; 2) Family Treatment Apartment; 3) Home Treatment; 4) Recovery within the community. The investigators will use a retrospective, control group (N=60) that matched the prospective group in age, sex, ED diagnosis, and severe symptomatology. Primary variables regarding Body Mass Index (BMI), ED symptomatology, functionality, recovery (yes/no), type of outpatient services (low/mid/high intensity), number of readmissions, and patient experience will be assessed at discharge, and after 6 and 12 months. Secondary variables include anxiety, depression, readiness to recover, quality of life symptoms, caregiver skills, and functionality of the family
