Abstract

The Stages of Change Readiness and Treatment Eagerness Scale (SOCRATES), a 19-item instrument developed to assess motivation to change alcohol use problems, has been used in various settings. In this study, 19 items of the original scale are adapted for gambling addiction. The proposed SOCRATES-G is composed of the adapted items. The purpose of this study was to verify the reliability and validity of SOCRATES-G, which is optimized for Korean adults presenting for specialized gambling treatment. A total of 2505 problem/pathological gamblers (male 97%) seeking treatment in community settings completed SOCRATES-G. Explanatory factor analyses yielded 3 unrelated factors that were stable across rotations and were the same as those in the original version of SOCRATES: Recognition, Ambivalence, and Taking Steps. The scale also shows a high Cronbach’s alpha. There is a suitable convergence observed between the SOCRATES-G scores and those of the reference scales. The SOCRATES-G scores showed excellent sensitivity to change and ability to distinguish recovered from unrecovered clients after treatment. A cutoff-score of ≥24 for the Recognition sub-scale was found to have 78% sensitivity and 41% specificity for gambling recovery, a cutoff-score of ≥9 for the Ambivalence sub-scale was found to have 60% sensitivity and 63% specificity, and a cutoff-score of ≤31 for the Taking Steps sub scale was found to have 46% sensitivity and 87% specificity. The implications and limitations of the present study along with suggestions for future research are discussed.
