The aim of this study was to examine the reliability and validity of the Korean version of the Impaired Control Scale (K-ICS), a scale to screen patients with alcohol use disorder.
Participants were 173 inpatients with alcohol use disorder (AUD), and 174 normal controls (NC). Both AUD and NC groups completed the K-ICS as well as the Alcohol Dependence Scale (ADS), the Alcohol Abstinence Self-Efficacy Scale (AASES), the Brief Self-Control Scale (BSCS), and the Hospital Anxiety and Depression Scale (HAD).
The internal consistencies of K-ICS were good in both AUD and NC. A good convergent validity was clearly shown by significant correlations with the ADS and the AASES, respectively. But the K-ICS had no or weak correlations with the BSCS and the HAD. The ROC curve analyses indicated that the optimal cut-off points of failed control (FC) and predicted control (PC) were estimated as >15 and >13, respectively. Hierarchical multiple regression analysis suggested that FC is a robust predictor of the severity of AUD.
The K-ICS, especially FC subscale of it appears to be a valid and reliable measure of impaired control among both clinical and non-clinical sample.
本研究旨在检验韩国版失控量表（K-ICS）的信度和效度，该量表用于筛查酒精使用障碍患者。
参与者包括173名酒精使用障碍（AUD）住院患者和174名正常对照（NC）。AUD组和NC组均完成了K-ICS以及酒精依赖量表（ADS）、戒酒自我效能量表（AASES）、简易自我控制量表（BSCS）和医院焦虑抑郁量表（HAD）。
K-ICS在AUD组和NC组中的内部一致性均良好。分别与ADS和AASES显著相关，清楚地显示出良好的收敛效度。但K-ICS与BSCS和HAD无相关性或相关性较弱。ROC曲线分析表明，失控（FC）和预测控制（PC）的最佳截断点分别估计为>15和>13。分层多元回归分析表明，FC是AUD严重程度的有力预测指标。
K-ICS，尤其是其FC子量表似乎是临床和非临床样本中失控情况的有效且可靠的测量工具。
