A Meta-Analysis of Single-Subject Studies on Community-Based Instruction for Individuals with Developmental Disabilities

The purpose of this study was to investigate the effects of community-based instruction for individuals with developmental disabilities through Tau-U analysis on community-based instruction using a single-subject study method. By searching studies on community-based instruction published in domestic academic journals during the past 10 years, a total of 28 studies were selected based on the inclusion/exclusion criteria. The selected studies were analyzed by major variables and their characteristics were examined. The effect size was analyzed by deriving the Tau-U value. The main results of the study were as follows. First, the effect size of the intervention of the community-based instruction for individuals with developmental disabilities was medium or above. Second, the effect size of each variable (eg. gender, school levels, type of disability, length of intervention period, length of each intervention) was also medium. In addition to discussing these results, some limitations and suggestions for further studies were discussed.
