The mother of a 7-year old boy with Down's syndrome was taught to use and to instruct others how to implement a behavioural management program to eliminate tantrum behaviour at home and in other social settings which was both frequent and persistent. The mother was the only person contacted throughout the program, which comprised three brief visits to the home and three telephone conversations. The program consisted of the extinction of tantrum behaviour using time-out from reinforcement coupled with differential reinforcement of appropriate behaviour. The behavioural objective of three consecutive days without tantrums was reached 18 days after the program was implemented and was maintained for a further 7 days, with only one minor relapse which occurred in a new setting. Six months later the improvement was being maintained. A brief discussion of factors affecting generalization and maintenance is included.
