The purpose of this study is to analyze the trend of single subject research related to verbal behavior analysis. For this purpose, 636 research papers were searched, and 30 papers related to verbal behavior analysis based on Skinner s Verbal Behavior were selected as analysis target papers according to the PRISMA procedure. Analysis target papers were analyzed by publication year, journal name, research participants, dependent and independent variables, research environment, and experimental design. As a result of analyzing the studies related to verbal behavior analysis, studies related to verbal behavior analysis were continuously published, and the dependent variables were verbal operant behaviors such as mand and tact, and higher verbal operant behaviors such as naming, and the independent variable was tact. Most of the research environment of the thesis analyzed in this study was a treatment room, and autism spectrum disorder was the most common type of disability among research participants. According to the results of this study, it was suggested that the study of verbal behavior analysis in Korea is at a relatively early stage, and the limitations of the study and future research are suggested.
