Reinforcement Sensitivity Theory predicts that those with a strong behavioral inhibition system (BIS) likely experience considerable anxiety and uncertainty during the transition out of university. Accordingly, they may continue to drink heavily to cope during this time (a period associated with normative reductions in heavy drinking), but only if they also have a strong behavioral approach system (BAS) to enhance the anxiolytic effects of drinking. The purpose of this study was to test this hypothesis. Participants completed online measures prior to and at 3-month intervals over the course of the year following graduation. As hypothesized, results showed that an elevated BIS predicted impeded maturing out, but only when the impulsivity facet of BAS was also elevated. In contrast, a strong BIS predicted rapid maturing out if BAS impulsivity was weak. Study findings advance our understanding of BIS-related alcohol misuse trajectories in young adulthood and provide direction for clinical interventions.
强化敏感性理论预测，那些具有强大行为抑制系统（BIS）的人在大学毕业过渡期间可能会经历相当多的焦虑和不确定性。因此，他们可能会在这段时间内继续大量饮酒以应对（这段时间与大量饮酒的正常减少相关），但前提是他们也有强大的行为趋近系统（BAS）来增强饮酒的抗焦虑作用。本研究的目的是检验这一假设。参与者在毕业后的一年中，在毕业前及每隔3个月完成在线测量。正如假设的那样，结果表明，较高的BIS预示着成熟过程受阻，但只有当BAS的冲动性方面也较高时才会如此。相比之下，如果BAS冲动性较弱，强大的BIS则预示着成熟过程迅速。研究结果推进了我们对成年早期与BIS相关的酒精滥用轨迹的理解，并为临床干预提供了方向。
