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.
A primary diagnosis of BDD, based on the diagnostic criteria of the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders. Confirmed by the assessor at the inclusion assessment using a semi-structured diagnostic interview. In cases where it is challenging to rule out the presence of actual physical defects that are clearly noticeable (e.g., if the area of concern is the genitalia), we will make a referral to an appropriate service for an expert opinion.

Age between 12 and 17 years. Confirmed by the caregiver/parent and subsequently by the medical record.
A minimum of one available caregiver/parent being able to co-participate and support the child/adolescent throughout the treatment. Confirmed by the caregiver/parent at the inclusion assessment.
Previous CBT for BDD for a minimum of five sessions with a qualified therapist within the 12 months prior to the inclusion assessment. Confirmed by the caregiver/parent at the telephone screening and/or the inclusion assessment and by the medical record.
Simultaneous psychological treatment for BDD or for any psychiatric comorbidity. Confirmed by the caregiver/parent at the telephone screening and/or the inclusion assessment and by the medical record.
Initiation, change of dosage or cessation of any selective serotonin reuptake inhibitors (SSRI) or antipsychotic drugs within the six weeks prior to the inclusion assessment. Confirmed by the caregiver/parent at the telephone screening and/or the inclusion assessment and by the medical record.
