The study examined associations between sensitivity to reward (SR), sensitivity to punishment (SP), positive and negative expectancies, and marijuana use in a college sample (N = 809). Marijuana users (n = 227) reported lower SP and greater SR than nonusers. SR attenuated the association between SP and the probability of marijuana use. SP attenuated the association between positive expectancies and the probability of marijuana use as well as the frequency of use among users. SP potentiated the association between negative expectancies and use. The results indicate that SP and SR have interactive effects and that SP moderates the strength of positive and negative cues for risk behavior.
该研究在一个大学样本(N = 809)中考察了奖励敏感性(SR)、惩罚敏感性(SP)、正负预期与大麻使用之间的关联。大麻使用者(n = 227)报告的SP低于非使用者,而SR高于非使用者。SR减弱了SP与大麻使用概率之间的关联。SP减弱了正性预期与大麻使用概率以及使用者使用频率之间的关联。SP增强了负性预期与使用之间的关联。结果表明,SP和SR具有交互作用,且SP调节了风险行为的正负线索强度。
