The purpose of this study was to analyze the experimental studies for children with autism based on quality indicators published between 1997 and March of 2010. Nine single subject design studies were published in major special education journals. To examine characteristics of the studies, we used 12 analytic variables such as participants, research setting, research design, intervention, target behavior, research procedure, measurement method, interrater reliability, social validity, treatment fidelity, result, and maintenance and generalization. We also used 7 quality indicators for single subject design studies such as description of participants and settings, dependent variable, independent variable, baseline, experimental control/internal validity, external validity, and social validity to evaluate evidence base of the studies. The results of this study indicated that studies on positive behavior support for children with autism have been conducted home setting as well as school setting. Also intervention setting, independent and dependent variables, and experimental control were not described in detail. Discussion and implications for future research were provided.
