Research Autism have published an Essential Guide to Challenging Behaviours and Autism
They describe it as examining the evidence on challenging behaviours in people on the autism spectrum. It examines guidance from the National Institute for
Health and Care Excellence (NICE) and the Social Care Institute for Excellence (SCIE). It also examines the research evidence on some of the interventions designed to prevent or reduce those behaviours. It is not intended to provide advice or recommendations on what you should or should not do about challenging behaviours in a specific individual.
