Abstract
The purpose of this study is to examine the Restricted, Repetitive Behavior and Interest types and characteristics for young children aged three to five that have been diagnosed with ASD according to the DSM-5 diagnostic criteria. For this study, the subjects were 144 children aged three to five who went through K-ADI-R, K-ADOS, K-WPPISI-III, and SMS among children diagnosed with ASD by DSM-5 from May 1, 2013 to December 31, 2021. The retrospectively analyzed results of all the medical record data of the subjects based on the purpose of this study were derived empirically. The results of this study are as follows. First, ‘Encompassing preoccupation or circumscribed patten of interest’ in the area of repetitive behavior and interest, ‘Failure regarding the development of peer relationship’in the area of qualitative abnormalities in reciprocal social interaction, and ‘Stereotyped repetitive or idiosyncratic speech’ in the area of qualitative abnormalities in communication. Second, This study also analyzes the correlation between Restricted, Repetitive Behavior and Interest, and any variables. ‘Age’ showed the most meaningful correlation followed by IQ and SQ. Restricted, Repetitive Behavior and Interest also show a meaningful correlation with ASD characteristics Interaction, Communication, and Play. Third, The subjects with Restricted, Repetitive Behaviors and Interest had a less meaningful correlation in age individually; however, they had a, more significant correlation in a group with lower IQ and SQ. Furthermore, they had qualitative abnormalities in Interaction, Communication, and Play. This retrospectively analyzed study, which acquired empirical results, is performed with the last eight years of medical records of young children with ASD. The results of this study are meaningful to lay the practical theoretical foundation for future work on restricted and repetitive behavior and interest in young children with ASD; in addition, the results contribute towards a direction for their intervention.
