The study has a mixed-methods strategy consisting of three elements: a randomized, multiple-baseline single-case design (n=35), a qualitative study (n=8-10) and a cost-effectiveness study (n=6). After obtaining written informed consent, participants will be randomly assigned to one of the five pre-defined baseline lengths (2-6 weeks) to increase the internal validity of the design.
The purpose of this study is to assess the (cost)effectivity of Equine assisted Therapy in adolescents with Autism Spectrum disorders.
