| Abstract: | In the present study, a nonconcurrent multiple baseline design was used to evaluate the effectiveness of simplified habit reversal in three children diagnosed with chronic vocal tic disorder. In two children, vocal tics were substantially reduced. In a third child, tics were not reduced, and the addition of a supplemental contingency management program was ineffective. Despite these mixed results, the treatment was viewed as acceptable to the children's parents in all cases as measured by a standard index of treatment acceptability. Implications of these findings are discussed. Copyright © 2002 John Wiley & Sons, Ltd. |
