Description

This alternating treatments design study compares two augmentative and alternative communication (AAC) strategies: the picture exchange communication system (PECS) and a voice output communication aid (VOCA) for three girls with Rett syndrome and severe to profound developmental disabilities. Outcomes included requests for preferred items, frequency of stereotyped behaviors, and measures of happiness and quality of life.

Treatment

"The data emphasized beneficial outcomes on participants’ mood (i.e. by increasing indices of happiness). It is consequently reasonable to indicate that the rehabilitative program improved their quality of life" (p. 1276). Two of the participants always chose VOCA, which was considered an indication of the feasibility and suitability of that intervention for individuals with Rett syndrome. The other participant equally chose PECS and VOCA, which authors attributed to her ability to "equally manage both communication opportunities" (p. 1276).
