Exclusion Criteria8

  • Global intellectual disability. Informed by the parent/caregiver and subsequently confirmed by review of the medical record or the neurodevelopmental assessment report, and additionally estimated with the two subtests matrix reasoning and similarities from the Wechsler Intelligence Scale for Children - fifth edition (WISC-V) or Wechsler Adult Intelligence Scale - fourth edition (WAIS-IV).
  • Comorbid psychotic disorder, bipolar disorder, severe eating disorder, severe depression, alcohol/substance dependence or hoarding disorder. Confirmed by the caregiver at the telephone screening and subsequently by the assessor at the inclusion assessment based on the structured diagnostic interview and, if required, the medical record.
  • Current suicidal intent or a previous suicide attempt within the last 12 months. Confirmed by the assessor at the inclusion assessment and, if required, the medical record.
  • Main symptom presentation consists of hoarding symptoms. Confirmed by the assessor at the inclusion assessment.
  • Completed CBT for OCD within the last 12 months prior to the inclusion assessment (defined as at least 5 sessions of CBT including ERP). Confirmed by the caregiver at the telephone screening or/and inclusion assessment and, if required, the medical record.
  • Simultaneous psychological treatment for OCD or anxiety. Confirmed by the caregiver at the telephone screening and/or inclusion assessment.
  • Initiation, dosage change or cessation of medication for OCD (primarily selective serotonin reuptake inhibitors, SSRIs) or behavioural symptoms of ASD (atypical antipsychotics) within the 6 weeks prior to the baseline assessment. Confirmed by the caregiver at the telephone screening and the inclusion assessment and, if required, the medical record.
  • Having a close relationship to an already included participant (e.g., sibling, cousin), to avoid being randomised into two different arms, with the risk of information "leaking" between the groups. Confirmed by the caregiver or assessor at the telephone screening and/or at the inclusion assessment.

Interventions

BEHAVIORALInternet-delivered exposure and response prevention (I-ERP)

The intervention is internet-delivered and therapist-guided, involving the child and at least one caregiver. It consists of two separate sets of modules, one for the child and one for the caregiver. The intervention consists of 12 modules, delivered over a maximum of 14 weeks. The treatment includes psychoeducation about ASD, OCD, emotions, healthy habits, the difference between repetitive behaviours in autism and OCD, how compulsions maintain the obsessions, and the rationale for ERP. The main focus of the treatment is ERP tasks based on the young person's individual goals. The modules also contain homework tasks that are meant to be completed between modules, mainly consisting of ERP. The final module includes a summary of the treatment and a relapse prevention plan. The version for parents consists of the same content as the child treatment, but with elaborated psychoeducation, and additional focus on strategies on how to assist their child in the different exposure tasks.

BEHAVIORALInternet-delivered stress management (I-SM)

The intervention is internet-delivered and therapist-guided, involving the child and at least one caregiver. It consists of two separate sets of modules, one for the child and one for the caregiver. The intervention consists of 12 modules, delivered over a maximum of 14 weeks. The treatment includes psychoeducation about ASD, OCD, healthy habits, and how stress is a contributor to OCD symptoms. The rationale is that targeting and reducing stress will have a beneficial impact on anxiety, obsessions, and compulsions. The main goal of the treatment is to learn how to reduce stress, mainly by using relaxation techniques such as deep breathing, progressive muscle relaxation, and imagery (cognitive) relaxation. The modules also contain homework tasks that are meant to be completed between modules, mainly consisting of relaxation tasks. The version for parents contains psychoeducation, as well as strategies on how to assist their child in the different relaxation tasks.
