A multiple baseline across groups design was used to investigate the effects of a treatment package on hand washing before lunch by five students with disabilities who attended a young adult educational program. To evaluate hand washing, a lotion called Glo Germ was applied to participants' hands. Glo Germ is visible under a black light, which allowed the quality of hand washing to be assessed by comparing the amount visible before and after hand washing using a 3-point scale. Following a baseline period in which hand washing was assessed, participants were exposed to a hand washing training procedure, which improved one participant's hand washing. Next, a lottery system was imposed in which the number of lottery tickets earned each day depended on the quality of hand washing, specifically, on the rating assigned (0, 1, or 2). This condition was associated with improved hand washing by the other four participants. Finally, a condition adding feedback to the lottery system resulted in further improvements in the quality of hand washing for all participants. Follow up data indicated modest maintenance of hand washing after lunch. These results suggest that treatment packages similar to that used in the present study merit further investigation and that Glo Germ is of value in ascertaining the quality of hand washing.
采用跨组多个时间基线设计，研究了一套治疗方案对参加青年教育项目的 5 名残疾学生午餐前洗手的影响。为了评估洗手效果，在参与者的手上涂抹了一种名为“Glo Germ”的乳液。Glo Germ 在黑光下可见，这使得通过使用 3 分制比较洗手前后可见的量，来评估洗手质量成为可能。在进行洗手评估的基线期之后，参与者接受了洗手培训程序，该程序提高了一名参与者的洗手质量。接下来，实施了抽奖系统，每天获得的彩票数量取决于洗手质量，具体而言，取决于分配的等级（0、1 或 2）。这种情况与其他四名参与者的洗手质量提高有关。最后，将反馈添加到抽奖系统中，导致所有参与者的洗手质量进一步提高。随访数据表明，午餐后洗手的保持情况尚可。这些结果表明，类似于本研究中使用的治疗方案值得进一步研究，并且 Glo Germ 在手卫生质量的确定方面具有价值。
