An effective and acceptable treatment alternative for chronic thumb- and finger-sucking.

Evaluated treatment for thumb-sucking in a randomized trial. Study included 22 children, ages 4-11, who displayed chronic thumb-sucking. Treatment included aversive taste and a reward system. Significant results were obtained at posttest, with 12 cessations at 3-month follow-up and 20 at 1 year. Participating parents, pediatricians, and pediatric psychologists validated treatment acceptability. Results support the treatment as an alternative to common medical and dental advice about thumb-sucking. Directions for future research are discussed.
