Effects of a positive support approach to enhance communicative behaviors of children with mental retardation who have challenging behaviors

This study investigated effects of a positive behavior support plan accompanied by an augmentative and alternative communication (AAC) intervention on the reduction of challenging behaviors manifested by children with moderate and severe mental retardation. A multiple-probe design across participants was used for collecting data on various challenging behaviors exhibited by students including: self-injurious behaviors, pinching, pulling, screaming, and crying. All behaviors were assessed using functional assessment, followed by a positive AAC support plan created by the school team. Participants were taught to use more appropriate alternative means to communicate. Results indicated a reduction in the percentage of intervals of challenging behaviors. The positive support plans created by the whole school staff used AAC for enhancing communicative behaviors. This plan provided students with alternatives, which also enabled them to enhance the learning of class material.
