Choice and preference assessment research with people with severe to profound developmental disabilities: a review of the literature.
Since the last major empirical review on choice interventions and preference assessments among people with severe to profound developmental disabilities (Lancioni, O'Reilly, & Emerson, 1996) the body of research in this area has grown extensively. This paper reviews thirty studies carried out between 1996 and 2002 that have been sorted into four categories. These categories are (a) building choice opportunities into daily contexts; (b) assessing the effects of choice making on various parameters of behavior; (c) assessing preferences; and (d) assessing the effectiveness of various preference assessment formats. The main findings in these studies were that choice interventions led to decreases in inappropriate behavior and increases in appropriate behavior, and that various preference assessments could be used to identify reinforcing stimuli. The findings are discussed in relation to technical and practical rehabilitation questions. Potential issues for future research are also examined.
