Gray's Reinforcement Sensitivity Theory (RST) predicts that the Behavioral Inhibition System (BIS) may relate to coping-motivated problem gambling, given its central role in anxiety. Studies examining the BIS-problem gambling association, however, are mixed. The revised RST posits that the Behavioral Approach System (BAS) may moderate the effect of the BIS on coping-motivated problem gambling. A concurrently strong BAS may highlight the negatively reinforcing effects of gambling, which may strengthen coping motives and increase gambling-related harms. We examined these interactive effects to clarify the moderators and mediators of the negative reinforcement pathway to problem gambling. Data came from a larger investigation of problem gambling among individuals with mood disorders. All participants (N = 275) met criteria for a lifetime depressive or bipolar disorder. During a two-day assessment, participants completed a diagnostic assessment and self-reports. Mediated moderation path analysis showed positive indirect effects from the BIS to problem gambling via coping motives at high, but not at low, levels of BAS-Reward Responsiveness and BAS-Fun Seeking. Enhancement motives were also found to mediate the associations of BAS-Fun Seeking and BAS-Drive with problem gambling. Reward Responsiveness and Fun Seeking facets of the BAS may strengthen coping gambling motives within the mood disorders.
格雷的强化敏感性理论（RST）预测，行为抑制系统（BIS）可能与应对动机性赌博问题有关，因为它在焦虑中起着核心作用。然而，研究 BIS-赌博问题关联性的研究结果不一。经过修订的 RST 假设，行为趋近系统（BAS）可能会调节 BIS 对应对动机性赌博问题的影响。同时具有强大 BAS 的人可能会突出赌博的负强化效应，这可能会增强应对动机并增加与赌博相关的伤害。我们研究了这些交互作用，以阐明问题赌博的负强化途径的调节因素和中介因素。数据来自对心境障碍患者中赌博问题的更大规模调查。所有参与者（N=275）都符合终生抑郁或双相情感障碍的标准。在为期两天的评估中，参与者完成了诊断评估和自我报告。中介调节路径分析表明，在 BAS-奖励反应性和 BAS-寻求乐趣的高水平，但不是 BAS-寻求驱动的低水平，BIS 对赌博问题的影响通过应对动机产生积极的间接影响。还发现增强动机可以调节 BAS-寻求乐趣和 BAS-寻求驱动与赌博问题之间的关联。BAS 的奖励反应性和寻求乐趣方面可能会在心境障碍中增强应对赌博的动机。
