John V. Stokes, John Randall Skin Picking is common challenging behavior exhibited among individuals with Prader-Willi Syndrome. Often times the occurrence of this behavior can result in infection and other complications that can result in more intrusive medical issues. This study reviews the use of functional analysis to determine the environmental variables controlling challenging behavior in 2 children and three adults. Additionally the study review the prescribed treatment used to decrease challenging behavior and teach adaptive replacement behaviors. By combining the antecedent manipulation of the environment and the use of non-contingent attention was sufficient to reduce picking and tantrum of individuals with Prader-Willi syndrome. Warning stimuli were then used to help him discriminate between permitted and prohibited behavior during sessions in which picking and tantrum was not directly observed. This procedure resulted in decreases in picking and tantrum behavior. Reliability data was collected during 50% of all treatment session; there was a mean inter-observer agreement of 95% during treatment session.
