病理性赌博 (PG) 患者的决策功能失调可能是由奖励驱动过程占主导地位造成的，表现为较高的冲动性。在当前的研究中，我们检查了（1）PG 是否表现出与主导奖励驱动流程相关的特定决策障碍，而不是与战略规划缺陷相关；（2）这些障碍是否与冲动有关。根据 DSM-IV，19 名 PG 和 19 名匹配的对照受试者进行了剑桥赌博任务 (CGT) 来评估决策。延迟贴现范式 (DDP) 以及 UPPS 冲动行为量表（测量紧迫性、预谋、毅力和感觉寻求）作为冲动性的多维测量。结果显示，(1) PG 在 CGT 中表现出更高的风险寻求和直接奖励关注，相反，其战略规划与对照组相当。 (2) 决策障碍与更严重的延迟贴现有关，特别是与紧迫性的增加和预谋的减少有关。我们的研究结果表明（1）有必要理清决策成分，以改善 PG 的病因学模型；（2）紧迫性和预谋与不利的决策特别相关，应在侧重于情绪容忍和控制策略的干预策略中解决。 (C) 2014 Elsevier Ireland Ltd. 保留所有权利。
Dysfunctional decision-making in individuals with pathological gambling (PGs) may result from dominating reward-driven processes, indicated by higher impulsivity. In the current study we examined (1) if PGs show specific decision-making impairments related to dominating reward-driven processes rather than to strategic planning deficits and (2) whether these impairments are related to impulsivity. Nineteen PGs according to DSM-IV and 19 matched control subjects undertook the Cambridge Gambling Task (CGT) to assess decision-making. The delay discounting paradigm (DDP) as well as the UPPS Impulsive Behavior Scale (measuring urgency, premeditation, perseverance and sensation seeking) were administered as multidimensional measures of impulsivity. Results revealed that (1) PGs exhibited higher risk seeking and an immediate reward focus in the CGT and, in contrast, comparable strategic planning to the control group. (2) Decision-making impairments were related to more severe delay discounting and, specifically, to increased urgency and less premeditation. Our findings suggest (1) the necessity to disentangle decision-making components in order to improve etiological models of PGs, and (2) that urgency and premeditation are specifically related to disadvantageous decision-making and should be tackled in intervention strategies focusing on emotion tolerance and control strategies.
