Objective:
This paper presents the results of a randomized controlled trial measuring the efficacy of a video-based skills training to decrease burden and psychological distress in caregivers of inpatients treated for an eating disorder in specialized hospital units.
Method:
Two hundred eighty-five caregivers were randomized to either the video intervention (N = 147) or the control group (N = 138). Caregivers' primary outcomes were assessed via Eating Disorder Symptom Impact Scale, Accommodation and Enabling Scale and General Health Questionnaire-12 at baseline and three-months follow-up.
Results:
Acceptability of the intervention was high. Receiving additional external professional help like psychotherapy or clinical counselling was identified as a moderator contributing to the efficacy of the intervention. Caregivers' burden (Eating Disorder Symptom Impact Scale) and psychological distress (General Health Questionnaire-12) were reduced by the intervention but not caregivers' accommodating behaviours (Accommodation and Enabling Scale).
Conclusion:
The video training is a promising approach and effective supplement for caregivers of patients with an eating disorder. Additional professional help to caregivers increases the effectiveness of the intervention. Copyright © 2017 John Wiley & Sons, Ltd and Eating Disorders Association.
