Internet-delivered cognitive-behaviour therapy for adolescents with body dysmorphic disorder

EXPERIMENTAL

Cognitive-behaviour therapy, Exposure and response prevention (ERP)

Behavioral: Exposure and response prevention (ERP)

Interventions

The treatment is Internet-delivered and therapist-guided, involving both the adolescent and at least one parent. The treatment consists of two separate sets of modules, one for the adolescent and one for the parent, each with separate logins. The ICBT intervention consists of 12 modules, delivered over a maximum of 14 weeks. The main goal of treatment is to help the young person to stop avoiding anxiety-provoking situations by undertaking exposure tasks and to stop doing unhelpful repetitive behaviours and rituals, known as response prevention. Every module also contains homework tasks that mainly consists of exposure and response prevention (ERP). Parents are also often involved in the patients' rituals and avoidant behaviours (known as family accommodation), which may contribute to maintain the BDD symptoms. Involving parents facilitates modification of these unhelpful patterns.

Sexall
Healthy VolunteersNo
Age GroupsChild (0-17)

You may qualify if:

  • Age 12 to 17 years, confirmed by the caregiver and subsequently by the patient record system Take Care.
  • A diagnosis of BDD, based on the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), confirmed by the assessor at the pre-treatment assessment.
  • A total BDD severity score on the BDD-YBOCS-A ≥24. confirmed by the clinician-reported BDD-YBOCS-A performed at the pre-treatment assessment.
  • A minimum of one available caregiver (parent) to support the child/adolescent throughout the treatment. Confirmed by the caregiver at the telephone screening or/and pre-treatment assessment.
  • Regular access to a desktop or laptop computer connected to the Internet, with the ability to receive e-mails, as well as a mobile phone to receive SMS (one of each per family is enough). Confirmed by the caregiver at the telephone screening or/and pre-treatment assessment.

You may not qualify if:

  • Previous CBT for BDD for a minimum of eight sessions with a qualified therapist within the 12 months prior to assessment. Confirmed by the caregiver at the telephone screening and/or pre-treatment assessment.

Confirmed by the caregiver at the telephone screening and/or pre-treatment assessment, with help of information from the caregiver and the child/adolescent, and the MINI-KID interview.
  • Immediate risk to self or others requiring urgent medical attention, such as current risk of suicide or self-injurious behaviours. Confirmed by the assessor at the telephone screening and/or face-to-face or video conference pre-treatment assessment, with help of information from the caregiver and the child/adolescent, and the suicide questions on the MINI-KID interview.
