The purpose of this study is to understand the domestic research trend of the sociability developmental programs targeting infants with disability and those at risk, by analyzing twenty-one studies published in domestic journals from 1998 to 2018. Our major focus in researching the studies was to analyze their research target, research type, program designs and results, as well as their mitigating methods. As a result, they were classified into 14 studies that involve infants at the risk of developing disability and 7 studies involving the infants with disability. As for the type of research, 18 studies were identified as research with experiments. In terms of program design, most of research setting was home. There was relatively a small portion of research, with 10 studies examining the maintaining effect of the program. The study implemented naturalistic intervention as the independent variable. For the dependent variable, it appears that many of studies attempted on using changes in the reciprocal relationship between the mother and the infant or the teacher and the infant. The overall study results suggest that the program positively effected on the sociability development of the infant. Parents were individually contacted to inspect and demonstrate the project. Therefore, further studies on the educational implementation and the support for infant’s optimal development in sociability will be needed and should be sustained in the future.
