Abstract

|
Objectives：This study is aimed to assess the reliability and validity of the Twelve Step Scale which are newly developed to observe the direct effect of the twelve step facilitation therapy that has been widely used for the treatment of patients with alcohol dependence.
Methods： 110 patients who were diagnosed with alcohol dependence by psychiatrists using DSM-TR criteria agreed to participate in the study. Subjects were assessed by questionnaires including demographic data and alcohol related clinical rating scales such as Twelve Step Scale, Korean version of Alcohol Use Disorders Identification Test, Alcohol Dependence Scale, Hanil Alcohol Insight Scale when informed consents were acquired. Four weeks later after initial assessment, Twelve Step Scale was reassessed for subjects who were treated over 3 months at the same hospital without recent admission or discharge for a month.
Results： The average of the Twelve Step Scale was higher in female patients than in male. In addition, there is positive correlation between HAIS and Twelve Step Scale. According to factor analysis, Twelve Step Scale has two factors. The results showed significant internal consistency reliability(Cronbach’s α=0.92) but did not show reasonable test-retest reliability.
Conclusion： This study showed that the Twelve Step Scale had reasonable reliability and validity except test-retest reliability. Thus the Twelve Step Scale can be used to assess the direct effects of twelve step facilitation therapy, which in turn might contribute to enhance twelve step facilitation therapy in the future.
