Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Anorexia Nervosa Case
Participants in this group have a life-time history of anorexia nervosa as determined by an algorithm applied to their responses to an eating disorders screening questionnaire (ED100K) that is based on the Structured Clinical Interview for Axis 1 Disorders.
Eating disorder diagnosis group
This is an observational study, no active intervention is applied. Participants are assigned to an eating disorder diagnosis group based on their lifetime history of disordered eating behaviors and symptoms.
Bulimia Nervosa Case
Participants in this group have a life-time history of bulimia nervosa as determined by an algorithm applied to their responses to an eating disorders screening questionnaire (ED100K) that is based on the Structured Clinical Interview for Axis 1 Disorders. These participants do not have a history of anorexia nervosa.
