This study evaluates two procedures for the elimination of nocturnal thumbsucking in a 10-yr-old boy. The subject's mother recorded the occurrence of thumbsucking four times each night. Reliability checks were done twice a week by another family member. A plastic splint, usually employed to protect a damaged thumb, was placed on the subject's thumb at bedtime. The results showed that when the splint was used, the incidence of thumbsucking decreased from 100% of the checks made during baseline to 0% during intervention. Several naturally occurring and one planned reversal demonstrated the effectiveness of the splint in controlling thumbsucking.
本研究评估了两种消除一名10岁男孩夜间吮指习惯的方法。受试者的母亲每晚记录四次吮指行为的发生情况。另一名家庭成员每周进行两次可靠性检查。一个通常用于保护受伤拇指的塑料夹板在睡前被放置在受试者的拇指上。结果显示，使用夹板时，吮指发生率从基线期检查的100%降至干预期的0%。几次自然发生的以及一次计划好的反转证明了夹板在控制吮指方面的有效性。
