Relationship of Tridimensional Personality Questionnaire scores and smoking variables in female and male smokers.

The Tridimensional Personality Questionnaire (TPQ) was developed by Cloninger (1986) to measure heritable variation in three patterns of response to environmental stimuli: novelty seeking, harm avoidance, and reward dependence. Cloninger (1987) used the TPQ to identify two types of alcoholism: Type 1 (low novelty seeking, high harm avoidance and reward dependence; both male and female) and Type 2 (high novelty seeking, low harm avoidance and reward dependence; predominantly male). To determine whether characteristic patterns exist in smokers, we administered the TPQ to 119 female and 121 male smokers, along with the Fagerstrom Tolerance Questionnaire (FTQ, a measure of nicotine dependence), the Russell Motives for Smoking Questionnaire (RMSQ), and the Spielberger State-Trait Anxiety Inventory (STAI/trait). Compared with a normative sample, our sample exhibited elevated scores on the Novelty-Seeking scale; female smokers were somewhat overrepresented in the highest quartile of the Harm-Avoidance scale; both genders tended to be clustered in the lower quartiles of the Sentimentality-Attachment-Dependence subscale of the Reward-Dependence scale and in the highest quartile of the Persistence subscale. Female smokers showed a significant positive association between Harm Avoidance and FTQ scores, and Harm Avoidance was positively correlated with several RMSQ factors (including Additive smoking) in both genders. These findings suggest that the likelihood of becoming a smoker may be a function of novelty seeking and reward dependence, whereas degree of dependence or addiction once the habit is entrained may be linked to harm avoidance. Our observations establish the potential utility of the TPQ as a tool for examining environmental and heritable variation in smoking behavior and may contribute to improved strategies for prevention and treatment of smoking.
