Administered a 6-hr test battery containing a smoking inventory to a large college sample of 361 Ss. Smokers tended to be more extraverted, more distress prone, more liberal, more open to experience, and more inclined to favor spontaneity than nonsmokers. Analysis of the smoking inventory yielded 11 factors. While sharply defined subtypes of smokers were not found, it was possible to broadly distinguish a pattern of maladjustive smoking and a pattern of adjustive smoking. Maladjustive smoking was characterized by tension, ingrained habit, and addictive symptoms. It tended to be associated with high anxiety, self-dissatisfaction, low experienced control, and a lack of organization. The adjustive pattern was characterized by greater pleasure and relief from tension, and was more closely associated with control, productivity, and a positive relationship to the environment.
