Abstract
|
|
|
This study was performed to examine the reliability and validity of DiClemente’s processes of change scale (SPOC)
and readiness to change scale (SRTC) for alcoholic patients by means of Korean version. The subject of the study were
163 alcohol dependence patients who were admitted. The results were as follows：1) The reliability of the Korean version
that was examined by internal consistency was found to be high (Cronbach alpha of SPOC was .94 and that of SRTC
was .85). 2) Factor analysis of 65 items resulted in a seven factor solution accounting for 49.3% of total explained variance.
The seven factors were interpreted as self-reevaluation and environmental reevaluation, helping relationships and feedback, consciousness raising, self-liberation, interpersonal system/ control stimulus, stimulus control, and physical intervention. Among the seven factors, stimulus control was discarded because of the proportion of that factor was so small. 3) In the correlations between stage and processes of change, the subscales of the SPOC, except physical intervention and interpersonal system/control stimulus, were significant correlated with contemplation, action and maintain stages. In conclusion, there are similarity and difference between the results of this study and original description. Further study is indicated to understand cultural implication and to evaluate general applicability of the scale.
