本研究测试的假设，冲动性将预测感知的积极和消极的加强吸烟。第二个假设是，冲动性和吸烟强化预期之间的关系将介导的自我导向的性格特征。报告吸烟的大学生（n=202）参加了调查研究。分层回归分析证实，冲动性预测了对吸烟的积极（β = 0.22，p = 0.001）和消极（β = 0.25，p= 0.001）强化的预期。这些关系也是由自我导向调节的。结果表明，在依赖的早期阶段，冲动的吸烟者可能会吸烟，因为他们希望吸烟是非常愉快的，以及帮助消除负面影响的发作。此外，他们对吸烟的期望值升高可能与难以适应具有挑战性的环境和朝着长期目标努力有关。(c)2006爱思唯尔有限公司保留所有权利。
The present study tested the hypothesis that impulsivity would predict perceptions of positive and negative reinforcement from smoking. The secondary hypothesis was that the relationship between impulsivity and smoking reinforcement expectations would be mediated by the character trait of self-directedness. College students (n=202) who reported smoking cigarettes participated in the survey study. Hierarchical regression analyses confirmed that impulsivity predicted expectations about positive (beta =.22, p =.001) and negative (beta =.25, p=.001) reinforcement from smoking. These relationships were also mediated by self-directedness. Results suggest that impulsive smokers in the early stages of dependence may smoke because they expect smoking to be extremely pleasurable as well as to help dispel bouts with negative affect. Further-more, their elevated expectations about smoking may be related to difficulties adapting to challenging environments and working toward long-term goals. (c) 2006 Elsevier Ltd.
