A single subject simultaneous treatment design, within a multiple baseline framework, was used to test the efficacy, contrast effect and differential effectiveness of two durations of time-out (TO). With two children on the autistic ward of a residential mental hospital serving as subjects, the TO procedure was demonstrated to be effective in reducing target behavior. No statistically significant difference was found between the 2 minute and 5 minute TOs and limited support for the existence of a contrast effect was revealed. It was concluded that strategies for the facilitation of the use of the shortest TO interval possible should be adopted and the importance of rigorous research within the applied setting was discussed.
