An evaluation of positive behavioural support for people with very severe challenging behaviours in community-based settings

This study employs a multiple baseline across individual design to describe positive behaviour support for five people in community settings. The individuals represent all people with intellectual disability residing in one county with long-standing challenging behaviour resulting in serious physical injury. Five types of outcome are presented: rates of behaviour, rates of medication, psychiatric symptomatology, quality of life and revenue costs. The systems of support required to maintain outcomes and develop real lifestyles include behaviour support planning, mental health review, on-call intensive support and emergency respite care. Behaviours reduced to near-zero levels following implementation of positive behaviour support and improvements were sustained over 24 months. The use of psychotropic medications reduced by 66 percent over the same period. Quality of Life Questionnaire scores improved significantly for three of the five participants. The results are discussed in the context of a framework for supporting people with severe challenging behaviours in the community.
