Abstract
A systematic replication of Van Houten and Rolider's (1984) response prevention study to eliminate nocturnal thumbsucking behavior was performed. Differences were related to the fading steps as well as the treatment duration (a shorter period), and followup (one year). A 5-year-old girl participated in this study. Response prevention procedures led to the suppression of thumbsucking behavior, which was maintained during the different fading conditions as well as during the follow-up period. Additional advantages other than the efficacy of the procedure to eliminate a chronic behavior were emphasized, such as the use of mainly positive interactions, the short duration of treatment, and the convenience for the child and her parents.
