“Rep-Mod”: An Intervention Model for Restricted, Repetitive Behaviours and Interests

This chapter presents the “Rep-Mod”, a whole person–environment-focused intervention model that integrates sensory-based and behavior-based intervention techniques, addressing RRBI in individuals with ASD. The strengths of the model lie in its functional analysis regarding the differential advantage or disadvantage of RRBI in the life each individual. Thus, RRBI that are considered as hindering adaptation and well-being are targeted as behaviors that should be decreased or eliminated, whereas RRBI that are judged as potential assets are integrated into daily life activities to increase adaptation and well-being. The model is dynamic such that each cycle of evaluation, intervention, and post-intervention re-evaluation forms the next entry level for further intervention.
