Application of Immobilization Time-Out in Management Programming with Developmentally Disabled Children

Abstract

Time-out procedures are employed frequently in management programming with developmentally disabled persons. However, in some cases, use of time-out is rendered ineffective because the client is able to engage in alternative undesired behaviors during the time-out period. The present studies examined the effects of an immobilization time-out procedure to address this difficulty with two developmentally disabled children. The procedure consisted of holding the children in a seated position during the application of time-out. In Study I, immobilization time-out produced a dramatic reduction in tantrumous and aggressive behaviors of an autistic-like girl. In Study II, the procedure was effective in reducing aggression of a mentally retarded boy. For both studies, immobilization time-out proved to be a more efficient intervention when compared to differential reinforcement methods alone. Effects of treatment were long-lasting as revealed during follow-up observations occurring one to six months form conclusion of the studies. Relevant issues regarding the implementation and acceptability of immobilization time-out are discussed.
