ABSTRACT

The purpose of this study was to investigate a quantitative analysis of the effects of individualized positivebehavior supports by conducting a meta-analysis of studies with single-case research designs. In thismanner, a total of 28 articles published in Korean by 2017 were selected and were subsequently analyzedin the current study. For extracting visual data, the GetData Graph Digitizer 2.26 was used. Tau-Uvalues were calculated through a comparison of the intervals. The main results of the study were asfollows. First, the size of the intervention and maintenance effect of the individualized positive behaviorsupport was considered to be large. Second, the effect size was large regardless of the elementary, middle,and high school students, and the effect of the intervention was great for all students regardless of thetype of disability (e.g., autism, intellectual disability, multiple disabilities). Therefore, in the case ofpositive behavior supports on decreasing challenging behaviors, there was significantly larger interventioneffects which were noted when the researchers solely conducted interventions than were noted with relatedteam-based interventions. Finally, the limitations, suggestions for future research, and practical implicationsare discussed.
