Internet-delivered Cognitive-behaviour Therapy for Child and Adolescent Body Dysmorphic Disorder

Summary

The purpose of this trial is to evaluate the clinical efficacy, the cost-effectiveness and the 6-month durability of a therapist-guided, Internet-delivered cognitive-behavior therapy programme for children and adolescents with body dysmorphic disorder.

Conditions

• Body Dysmorphic Disorders

Interventions

BEHAVIORAL

Internet-delivered cognitive-behaviour therapy (ICBT)

The intervention is Internet-delivered and therapist-guided, involving both the adolescent and at least one caregiver. It consists of two separate sets of modules, one for the adolescent and one for the caregiver. The intervention consists of 12 modules, delivered over a maximum of 14 weeks. The first part includes psychoeducation about BDD and strategies to resolve possible ambivalence towards psychological treatment. The main goal of the treatment is to help the young person to stop avoiding anxiety-provoking situations (e.g., going to school or participating in social situations) by undertaking exposure tasks and to stop doing unhelpful repetitive behaviours and rituals (e.g., excessive mirror-checking, camouflaging), known as response prevention. Every module also contains homework tasks that are meant to be completed between modules and mainly consist of exposure and response prevention (ERP) tasks based on the young person's individual goals.

BEHAVIORAL

Internet-delivered relaxation treatment (IRT)

The intervention is Internet-delivered and therapist-guided, involving both the adolescent and at least one caregiver. It consists of two separate sets of modules, one for the adolescent and one for the caregiver. The intervention consists of 12 modules, delivered over a maximum of 14 weeks. The first part includes psychoeducation about BDD, how anxiety and stress are major contributors to BDD symptoms, and that targeting and reducing stress will have a beneficial impact on those symptoms. The main goal of the treatment is to teach the young person to relax in order to cope with anxiety and appearance concerns. The intervention mainly consists of a relaxation treatment and includes different relaxation skills such as deep breathing, progressive muscle relaxation, and imagery (cognitive relaxation). Every module also contains homework tasks that are meant to be completed between modules and mainly consist of relaxation tasks.
