본 연구는 후진형 행동연쇄와 최대-최소 촉구가 발달장애 아동의 일상생활 기술 수행에 미치는 효과를 살펴보았다. 연구 참여자는 특수학교 중학과정 2학년 아동 2명이다. 종속변인은 아동이 아침에 등교한 뒤 자신의 가방과 신발, 겉옷을 정리하는 일상생활 기술로 설정하였으며 독립변인으로 후진형 행동연쇄와 최대-최소 촉구를 중재로 제공하였다. 관찰 및 측정은 일상생활 기술을 아동에 따라 개별적인 6-10단계로 과제분석한 뒤 수행률의 변화를 살펴보았으며 이때 수행률은 아동이 수행한 과제분석 단계의 수를 전체 과제분석 단계의 수로 나누어서 백분율로 산출하였다. 실험설계는 행동간 중다간헐설계 방법을 사용하여 기초선 단계, 중재 단계, 유지 단계의 자료를 수집하였으며 기능적 관계가 입증되었다. 시각적 분석 결과, 후진형 행동연쇄와 최대-최소 촉구는 발달장애를 가진 아동의 일상생활 기술을 개선하는 데 효과가 있고 중재 효과는 일정 시간이 지난 후에도 유지되었다. 연구 전반에 관한 논의와 제한점, 제언을 서술하였다.


The purpose of this study was to investigate the effects of backward chaining and most-to-least prompting on the performance of daily living skills of children with developmental disabilities. Two second-grade students from the special middle school participated in this study. Daily living skills, organizing one's bag, shoes, and jacket when the students arrive at the school in the morning, was selected as the dependent variable. The backward chaining and the most-to-least prompting provided as interventions were selected as the independent variables. For observation and measurement, the change in the performance rate was examined after analyzing daily living skills in individual 6-10 steps for each child. In this case, the performance rate was calculated as a percentage by dividing the number of task analysis steps performed by the child by the total number of task analysis steps. Using a multiple probe baseline design across behavior, the data of baseline, intervention, and maintenance phase were collected and functional relation was verified. The result of visual analysis revealed that the daily living skills of children with developmental disabilities have improved effectively by the backward chaining and the most-to-least prompting, and these intervention effects were maintained even after a period of time. Discussions, limitations, and suggestions regarding the overall study were described.
