Clinical Trial Summary

The goal of this randomized controlled clinical trial is to compare the efficacy of outpatient family-based treatment versus enhanced cognitive behavior therapy for children and adolescents with eating disorders.

The main aim is to determine if enhanced cognitive behavior therapy has a similar efficacy as family-based treatment among children and adolescents with eating disorders receiving treatment in an outpatient setting. The main outcome is improvement in eating disorders psychopathology at the end of treatment.

Description:

Eating disorders (EDs) are severe mental illnesses, associated with high morbidity, increased mortality, and reduced quality of life. Despite treatment advancements, remission rates are modest. Even in specialized treatment settings offering evidence-based treatments such as family-based treatment (FBT), remission rates are about 50%. There is emerging evidence for the effectiveness of enhanced cognitive behavior therapy (CBT-E) for adolescents with EDs. However, no randomized controlled trial (RCT) has yet compared these two treatments.

The current study will compare FBT, which has proven efficacious and is currently recommended for adolescents with EDs, and the newer treatment approach of CBT-E in a large, national RCT. Young patients with all EDs (12-18 years of age) undergoing outpatient treatment from eight different clinics in Norway will be invited to participate in the study.

Primary aim:

This study is a randomized controlled trial comparing the efficacy of outpatient family-based treatment versus enhanced cognitive behavior therapy for children and adolescents with eating disorders. The main outcome is improvement in eating disorders psychopathology at the end of treatment.

Secondary aims:

To compare weight gain for underweight patients, changes in comorbid psychopathology including depression, self-esteem, family functioning, and quality of life at 6-and 12-months follow-up.

Potential moderators of outcome will be explored. Treatment satisfaction and experiences of the two different treatments will be investigated from the perspective of patients, parents, and clinicians. Data from the Norwegian Control and Payment of Health Reimbursements Database (KUHR), the Norwegian Patient Registry (NPR), and Social Security Database will be obtained to compare the direct and indirect costs of health care utilization for the two treatments.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Changes in family function	Change in parent ratings of family functioning measured by the subscale score on a well validated self-report questionnaire- the McMaster Family Assessment Device, General Functioning subscale. Scores on this subscale range from 12 to 48, where higher scores means worse level of family function.	Baseline, immediately after the intervention, 6 months after the end of treatment, 12 months after the end of treatment
Other	Changes caregiving experience and psychological symptoms	Change in parent ratings on the impact of eating disorder symptoms on caregiving experiences measured by a well validated, self-report measure -the Eating Disorders Symptom Impact Scale. Scores range from 0 to 96, where higher scores mean worse impact of eating disorder symptoms.	Baseline, immediately after the intervention, 6 months after the end of treatment, 12 months after the end of treatment
Other	Changes caregiving mental health	Change in parent ratings on the mental health symptoms by a well validated, self-report measure -the Hopkins symptoms checklist 25 items. Scores range from 1 to 4 where higher scores mean worse mental health symptoms.	Baseline, immediately after the intervention, 6 months after the end of treatment, 12 months after the end of treatment
Other	Direct and indirect costs of health care use for patients and parents/caregivers	Register data from the Norwegian Control and Payment of Health Reimbursements Database (KUHR), the Norwegian Patient Registry (NPR), and Social Security Database.	Baseline, immediately after the intervention, 6 months after the end of treatment, 12 months after the end of treatment
Primary	Change in eating disorder psychopathology	Change in global scores on a well-validated semi-structured interview of eating disorder attitudes and behavior, the Eating Disorder Examination - Interview. Possible scores range from 0-6 where higher scores indicate worse symptoms.	Baseline, immediately after the intervention.
Secondary	Change in eating disorder psychopathology	Change in global and subscale scores on a well-validated self-report questionnaire of eating disorder attitudes and behavior, the Eating Disorder Examination-Questionnaire. Possible scores range from 0-6 where higher scores indicate worse symptoms.	Baseline, immediately after the intervention, 6 months after the end of treatment, 12 months after the end of treatment.
Secondary	Change in weight (kg) for underweight participants (defined as those participants who are below 18,5 Body Mass Index (BMI) (kg/m2) at baseline or corresponding BMI to age and gender).	Weight gain in kilogram. Higher weight gain means better outcome.	Baseline, immediately after the intervention, 6 months after the end of treatment, 12 months after the end of treatment
Secondary	Change in depression	Change in global score on a well-validated self-report questionnaire of depression, the Beck Depression Inventory II. Possible scores range from 0 to 63 where higher scores mean worse symptoms.	Baseline, immediately after the intervention, 6 months after the end of treatment, 12 months after the end of treatment

Possible scores range from 0 to 63 where higher scores mean worse symptoms.	Baseline, immediately after the intervention, 6 months after the end of treatment, 12 months after the end of treatment
