研究和临床经验表明，冲动是病态赌博的一个基本特征。这项研究考察了由南橡树赌博屏幕(SOGS)评估的冲动行为(由延迟金钱奖励的贴现率定义)随病态赌博严重程度的变化程度。62名病态赌徒完成了延迟折扣任务、SOG、艾森克冲动量表、成瘾严重指数(ASI)，以及关于赌博和药物使用的问题，以门诊治疗病态赌博。在延迟折扣任务中，参与者在一系列延迟(6年至25年)中选择了大额延迟奖励(1000美元)和较小的更直接奖励(1-999美元)。每个参与者的延迟奖励折现率(k值)被计算出来，并使用线性回归来识别预测k值的变量。年龄、性别、受教育年限、药物滥用治疗史和吸烟史未能显著预测k值。艾森克冲动量表和SOG的得分都解释了k值变化的很大比例。SOG的预测值是艾森克量表的1.4倍。这些结果表明，在这个病态赌徒的样本中，在延迟贴现任务中，赌博严重程度是对冲动行为最好的单一预测因子。(C)2003爱思唯尔B.V.保留所有权利。
Research and clinical expertise indicates that impulsivity is an underlying feature of pathological gambling. This study examined the extent to which impulsive behavior, defined by the rate of discounting delayed monetary rewards, varies with pathological gambling severity, assessed by the South Oaks Gambling Screen (SOGS). Sixty-two pathological gamblers completed a delay discounting task, the SOGS, the Eysenck impulsivity scale, the Addiction Severity Index (ASI), and questions about gambling and substance use at intake to outpatient treatment for pathological gambling. In the delay discounting task, participants chose between a large delayed reward (US $1000) and smaller more immediate rewards (US $1-$999) across a range of delays (6 It to 25 years). The rate at which the delayed reward was discounted (k value) was derived for each participant and linear regression was used to identify the variables that predicted k values. Age, gender, years of education, substance abuse treatment history, and cigarette smoking history failed to significantly predict k values. Scores on the Eysenck impulsivity scale and the SOGS both accounted for a significant proportion of the variance in k values. The predictive value of the SOGS was 1.4 times that of the Eysenck scale. These results indicate that of the measures tested, gambling severity was the best single predictor of impulsive behavior in a delay discounting task in this sample of pathological gamblers.
