The purpose of this research was to identify the effects of vocational training through group home and
workplace instruction on the care task skill of individuals with intellectual disabilities. For this, three
individuals with intellectual disabilities, who were staying in general homes for 1~2 years being
unemployed after high school graduation, and have been living in the group home in a welfare center for
5~6 months, were selected as research subjects. The research design was composed of multiple probe
design across subjects, one of the techniques of single subject research, and the research condition was
composed of baseline, intervention, and maintenance. In the vocational training through group home and
workplace instruction, three teachers who were teaching the research subjects in the group home and three
workplace employees participated as instructors, and a training was provided to group home teachers and
workplace employees in advance. First, in the group home instruction of intervention program, the
instruction technique of ‘watching Internet medium’ was composed primarily by using the life information
video posted on the homepage of selected workplace. Also, an imaginary behavioral rehearsal (role play)
according to the 1:1 interaction method of instructors and research subjects was also formed as one step.
In addition, workplace instruction included movement prompting and language prompting, which were a
part of brief response prompting. The research subjects received intervention as a schedule of participating
continuously in workplace instruction, after group home instruction was complete. Care task skill, the
targeted behavior (dependent variable), was defined operant as a performance skill for the research subjects
to help geriatric patients hospitalized in elderly care hospitals with meals and facial wash; it was composed
as a total of 10 sub steps through task analysis. The research result demonstrated that the research
subjects effectively acquired and maintained care task skill through the intervention program.
