It has been reported that self-determination is closely associated with desirable
transition outcomes of an individual. There are, however, few Korean self-determination
measures reporting the technical characteristics and merits of the measures. The purpose
of this study is to examine the reliability and validity of a Korean version of the
Minnesota Self-Determination Scales (Abery, Smith, Stancliffe, & Elkin 2000).
Participants were forty adults with intellectual disabilities who resided in the three group
homes and one residential institution in a city of South Korea. A Korean version of the
Minnesota Self-Determination Scales (K-MSDS) was translated and back-translated by
the investigator and associated research team members for the study. The K-MSDS was
administered to the participants in an interview format. Nine culturally inappropriate
items were identified and modified by the investigator. Investigation of the test-retest
reliability, internal consistency reliability, and criterion-related concurrent validity were
the focus of this study.
The test-retest reliability results indicated that the K-MSDS had strong
correlations ranging from .842 to .943 (Pearson’s r). The K-MSDS had strong internal
consistency ranging from .967 to 993 (Cronbach’s α). Correlations for the criterionrelated
concurrent validity were computed between the K-MSDS and a Korean version of
Arc’s Self-Determination Scale (K-SDS). The results indicated that there were
acceptable correlations between the K-SDS and the K-MSDS ranging from .509 to .514
(Pearson’s r). However, the test-retest reliability and criterion-related concurrent validity
within a few domains of the K-MSDS were low.
