Benefits have been reported for certain institutionalized populations when mealtimes are arranged under normal, family-style conditions. In this study, we evaluated a program for teaching family-style mealtime skills to institutionalized persons with skill deficits greater than those targeted in previous research--the profoundly retarded. Results showed that the program, involving forward chaining with a less-to-more intrusive prompting sequence and contingent reinforcement, successfully taught four profoundly retarded persons several family-style skills. Also, systematic measures supported the durability of the skills, social validity of the behavior changes, acceptance of the program by staff trainers, and no detrimental changes in health-related variables associated with food consumption. However, results also indicated that beneficial corollary changes (e.g., increased peer communication) previously reported with higher skilled populations did not occur. These results suggest that with more seriously handicapped populations, multiple changes should not be assumed when normalizing institutional conditions; rather, specific skill training will probably be necessary.
据报道,当用餐时间按照正常的家庭式条件安排时,某些机构收容人群会从中受益。在本研究中,我们评估了一个项目,该项目旨在向机构收容的、技能缺陷比以往研究对象——重度智力迟钝者更大的人传授家庭式用餐技能。结果表明,该项目采用了从少到多的侵入性提示序列和偶然强化的正向连锁法,成功地教会了四名重度智力迟钝者几项家庭式技能。此外,系统测量结果支持了这些技能的持久性、行为改变的社会有效性、工作人员培训师对该项目的接受程度,以及与食物摄入相关的健康变量没有出现有害变化。然而,结果也表明,之前报道的在技能水平较高人群中出现的有益的附带变化(如同伴交流增加)并未发生。这些结果表明,对于残障程度更严重的人群,在使机构条件正常化时不应假定会出现多种变化;相反,可能需要进行特定的技能培训。
