 Patients are randomized to 1 of 3 groups. One group is given a copy of the CD-ROM program to complete at home over 10 weeks. At the end of each week, these patients upload and transmit their encrypted tracking data to the research coordinator. At the end of the treatment, participants who have not improved are offered a course of traditional manual-based group therapy, follow-up in an ongoing maintenance group in an eating disorders program, or an alternative treatment.
