An overview of behavioral strategies for reducing hand-related stereotypies of persons with severe to profound intellectual and multiple disabilities: 1995-2007.
This paper provides an overview of behavioral strategies used for reducing hand-related stereotypies (i.e., hand/finger mouthing, eye poking, self-slapping, and other hand-to-head/body responses) of persons with severe to profound intellectual and multiple disabilities. Computerized and manual searches were conducted to identify the studies carried out in this area between 1995 and 2007. Forty-one studies were identified which used five main strategies: (1) mechanical restraints employed alone or together with other intervention variables, (2) response blocking alone or together with other intervention variables, (3) noncontingent stimulation (environmental enrichment) with or without prompting or contingent reinforcement events, (4) contingency manipulations differing from those relied upon by the other strategies, and (5) programs based on microswitch clusters. The outcomes of the studies tended to be positive but occasional failures also occurred. Outcomes were discussed in terms of the characteristics of the strategies employed, the implications of the strategies for the participants' overall stimulation and occupational situation, and the overall practicality, applicability, affordability and potential of the strategies in the short and long term. Issues for future research were also examined.
