A Preliminary Validation Study of the Korean Version of the Minnesota Self-Determination Scales for Adults With Intellectual Disabilities

Abstract

The Minnesota Self-Determination Scale (MSDS) was translated into Korean. The Korean version was then validated using a sample of 40 individuals with intellectual disabilities between the ages of 19 and 45 years, the legal age of adults in South Korea. The evidence of the reliability and validity was examined. The test–retest was good (.84-.94). The internal consistency was excellent (.96-.99). The construct validity with other Korean translated self-determination measure (K-SDS) was acceptable (.50-.51). The findings indicated that the K-MSDS was an appropriate measure with acceptable psychometric properties. The Korean version was the first self-determination measure for adults with disabilities.
