    Abstract:
    Positive- and negative-reinforcement consequences of smoking were assessed using a self-report inventory. Data from 429 current smokers (348 women, 81 men) were subjected to an exploratory factor analysis, with concurrent validation of resulting scales in 288 current smokers (235 women, 53 men), controlling for sex and age. The solution with three factors--positive reinforcement, negative reinforcement, and smoking patterns--provided the clearest and most interpretable factor solution. The Michigan Nicotine Reinforcement Questionnaire (M-NRQ), which yields positive- and negative-reinforcement scales, was developed based on these results. Positive-reinforcement smoking was associated with higher scores on novelty seeking, reward dependence, alcohol dependence, and pleasurable sensations upon early smoking experimentation, and with lower scores on displeasurable sensations and nausea upon early smoking experimentation. Negative-reinforcement smoking was associated with higher scores for nicotine dependence, depression, anxiety, and harm avoidance. The M-NRQ has potential as a diagnostic tool for individualizing behavioral intervention and pharmacotherapy and also may be useful in identifying new phenotypes for genetic research on smoking.
