Meta-Analysis and Analysing Quality Indicators of Intervention on Problem Behaviors for Elementary Students with Autism Spectrum Disorders

By analysing the study designed for the single-subject of the problems behavior of elementary students with autism spectrum disorders in Korea, this study aims to discuss effective intervention on behavior problems for elementary school students with autism spectrum disorders. First, we examined general trend of studies according to 22 articles' study trend, research problems, subject of study, type of intervention, experimental design, percentage of non-overlapping data, and other qualitative factors related to single-subject design study. Second, we calculated and analysed PND for each factors of effect-sizes of intervention on problem behaviors. Third, we have done quality analysis based on quality indicators which were proposed by Kim Eun Kyoung(2015). Based on the analyses, we fond out that 1)the research of intervention for men was the most, and 2)intervention was done mainly on school, and 3)most of the interventor were experts. Also, a lot of researches excluded linearity of intervention and social validity and most studies used multiple baseline design across subjects for research of intervention on problem behaviors, and interventions mostly were based on cognitive ability and technology-oriented approach. Suggestions of this study were as follows: First, necessity of variety intervention considered child's characters. Second, necessity of evidence-based research. Third, necessity of research that experts and families work together for the intervention in child's problem behaviors. Fourth, necessity of ecological intervention through functional behavior assessment.
