Overview of study.
Sixty-four patients with AN and 66 patients with BN were enrolled in the study. Fifty-nine patients with AN and 57 patients with BN participated. Potentially eligible patients who were voluntarily admitted between July 2014 and April 2017 to cooperating treatment centers were approached by staff members and informed about the clinical study. Study eligibility criteria included female gender, age between 18 and 35 years, and a primary diagnosis of AN or BN. Exclusion criteria were current pregnancy, breast feeding, or intake of beta-blockers. Patients were assessed after treatment admission and three months later. Assessments included a clinician-administered diagnostic interview (60–90 minutes) and a self-report questionnaire (60 minutes).
