Treating Patients With Co-occurring Autism Spectrum Disorder and Substance Use Disorder: A Clinical Explorative Study.

CBT may represent a promising treatment option for individuals with ASD and SUD. The results suggest that patients' symptoms can be reduced by providing monthly ASD education and group supervision to therapists in ordinary SUD outpatient clinics. This group of patients need more sessions than other client groups, the therapy has to be adapted to ASD, ie, direct, individualised, and more extensive. Moreover, the patients need psychoeducation on ASD generally, social training, and support to organise several aspects of their lives and some patients need more support than can be provided in an outpatient clinic.
