Negative self-image and outcome in eating disorders: Results at 3-year follow-up

Participants
The present research was conducted within the framework of the Co-ordinated Evaluation and Research at Specialized Units for Eating Disorders in Sweden (CO-RED) project.

Participating centres offer a wide variety of treatment forms such as inpatient, day-patient, and outpatient forms of treatment, individual psychotherapy, family and group therapy,

Patients without complete data at follow-up reported higher scores on one variable at intake, namely key clinical symptoms (p = .04). However, the magnitude of this difference (Cohen's d = .12) was negligible. Cohen (1988) defines effect sizes < .20 as indicating
