Experimental: Virtual Reality-based Social Cognitive Training (VRSCT)

Patients in the experimental group will be offered 10 individual sessions of targeted, virtual reality assisted psychotherapy embedded in cognitive behavioral therapy (CBT), that aims at enhancing social cognition and daily life functioning. If the patient consents, two additional sessions will be offered in which the patient's relatives are invited to participate (one in the beginning of treatment and one at the end of treatment). The aim of the relative involvement is to enhance transfer from the therapy to the patients daily life. The treatment will be conducted by psychologists with an extensive knowledge in providing virtual reality assisted therapy. The treatment is manualized, and the therapists will receive ongoing supervision by a senior clinician having ≥ 25 years of experience in conducting assessment, treatment, and research with the autism spectrum population.

No_intervention: Treatment as Usual (TAU)

The treatment-as-usual (TAU) group will receive the standard treatment offered to adults diagnosed with ASD in Denmark. This commonly consists of four psychoeducational sessions as well as limited supportive counseling. Some adults with ASD also receive practical help in daily life situations in community settings. The TAU will be mapped upon trial completion.
