The Stages of Change Readiness and Treatment Eagerness Scale (SOCRATES) is an instrument used to measure the level of motivation in regards to changing drinking and other addictive behaviors. While some initial factor analysis studies on the SOCRATES described a three-factor orthogonal structure of the scale, some other studies found a two-factor correlated structure. Therefore, the primary objective of the present study was to test the validity of the Korean language version of the instrument using a Korean population. The study examined the factor structure of the Korean version of the SOCRATES with clinical samples consisting of 219 inpatients and 271 outpatients with alcohol dependency. An exploratory factor analysis with an alpha factoring method revealed a three-factor correlated structure (i.e., Taking Steps, Recognition, and Ambivalence). The factorial structure of the SOCRATES Korean version corresponded almost exactly to that of its original French version as well as the German version. Moreover, confirmatory factor analyses showed that a three-factor correlated structure provided the best fit for the data.
