本研究报告的前瞻性测试的后天准备模型，假设冲动影响吸烟通过形成更多的积极和更少的消极预期吸烟的影响。从不吸烟的大学新生（n = 400; 45%为男性）完成了基线访谈和基线后15个月的季度在线随访评估。结构方程模型表明，感觉寻求和消极紧迫感的冲动性成分对吸烟开始风险的影响分别由吸烟的正强化和负强化的预期介导。对吸烟的负面后果的预期预测启动，但没有调解的感觉寻求或消极的紧迫感的影响。研究结果是一致的后天准备模型，并表明，提高冲动与吸烟强化的预期提高，从而与吸烟开始的风险更大。
This study reports on a prospective test of the Acquired Preparedness Model, which posits that impulsivity influences cigarette smoking through the formation of more positive and fewer negative expectancies about smoking effects. College freshman never-smokers (n = 400; 45% male) completed a baseline interview and quarterly online follow-up assessments for 15 months after baseline. Structural equation modeling indicated that the effects of the impulsivity components of sensation seeking and negative urgency on risk of smoking initiation were mediated by expectancies for positive and negative reinforcement from smoking, respectively. Expectancies about negative consequences from smoking predicted initiation but did not mediate the effects of sensation seeking or negative urgency. Findings are consistent with the Acquired Preparedness Model and suggest that heightened impulsivity is associated with heightened expectancies for reinforcement from smoking, and thus with greater risk for smoking initiation.
