Anne-Marie Martin explains how a person-centred intervention reduced the incidence of challenging behaviour exhibited by a person with intellectual disabilities

This article presents a case study of how positive behaviour support improved the quality of life of a client, a young woman with a rare chromosomal disorder, in an Irish residential service for people with intellectual disability. The client’s biological, psychological and social presentations are outlined, including one of her challenging behaviours, scatolia which appeared to be linked to each of these elements of her life. In addition, her behaviour support plan, based on a full assessment, is described.
