Pathological Gambling is an impulse control disorder. Impulsivity has been investigated separately by neuropsychological tests and self-report scales. Although some studies have tried to correlate these approaches, their interaction has not been sufficiently explored among pathological gamblers (PG). In this study, we have compared 214 PG (162 with comorbidity and 52 with no comorbidity) to 82 healthy volunteers regarding the reaction time and number of errors at Go/No-go tasks, and scores on the Barratt Impulsiveness Scale (BIS). PG have committed more errors at the Go/No-go tasks and presented higher scores on the self-report scale. The neuropsychological tests and BIS composed a multinomial logistic model that discriminated PG from non-gamblers better than models having one or another type of measure. Impulsivity seems to be a multi-dimensional phenomenon, and PG a heterogeneous population in which different types of impulsivity are present.
病理性赌博是一种冲动控制障碍。冲动性已通过神经心理学测试和自我报告量表分别进行了研究。尽管一些研究试图将这些方法联系起来，但在病理性赌博者（PG）中，它们之间的相互作用尚未得到充分探索。在本研究中，我们比较了214名病理性赌博者（162名有共病，52名无共病）和82名健康志愿者在Go/No-go任务中的反应时间和错误数量，以及在巴拉特冲动性量表（BIS）上的得分。病理性赌博者在Go/No-go任务中犯的错误更多，在自我报告量表上得分更高。神经心理学测试和BIS构成了一个多项逻辑模型，该模型比仅采用一种或另一种测量方法的模型能更好地区分病理性赌博者和非赌博者。冲动性似乎是一个多维度现象，而病理性赌博者是一个异质性群体，其中存在不同类型的冲动性。
