ABSTRACT

Objective: The purpose of this study is to determine the prevalence rate and severity of challenging behaviors among people with intellectual disabilities living in institution settings. Methods: 419 with intellectual disabilities living thirteen institution settings where were in Gangwondo were conducted to determine the challenging behaviors. Utilizing the KBPI-01, three areas of challenging behavior (self-injurious, stereotyped, and aggressive/destructive) were assessed to frequency and severity. Results: A total of 53.2% showed self-injury, 68.3% stereotyped behavior, and 54.7% aggressive/destructive behavior, at a rate of at least once per month. The results showed severity of challenging behavior that a total of 53.2% showed self-injury, 67.8% stereotyped behavior, and 54.7% aggressive/destructive behavior. These correlations suggest that the frequency and the severity scales were highly. The profound level group was the most prevalent of self-injurious and stereotyped behavior and the unspecified level group was the most prevalent of aggressive/destructive behavior. In a low age group (3~20 years) was the most prevalent of self-injurious and stereotyped behavior. The 51~74 years group showed the most prevalent of aggressive/destructive behavior. Conclusion: These results suggested the need for enhanced understanding of seriously challenging behaviors among individuals with intellectual disabilities and are important for analyzing the therapeutic service systems.
