The relationship of smoking to selected performance and personality factors among university students

This study investigated the relationship of cigarette smoking to selected performance and personality factors among 151 university students. Smokers and nonsmokers were compared by means of individual t tests with regard to grade point average, verbal and quantitative SAT scores, and the 11; scales of the Omnibus Personality Inventory (OPI). The results revealed a statistically significant difference between the two groups on 8 of the 114 OPI scales: Theoretical Orientation, Complexity, Autonomy, Religious Orientation, Impulse Expression, Personal Integration, Altruism, and Practical Outlook. No significant differences, however, were found between smokers and nonsmokers on any of the 3 measures of academic performance.
