Understanding factors related to nonsmoking intention among college students

Abstract

Objective: While cigarette smoking in the United States has declined, the age range of smoking initiation has risen to include young adults. This study investigated the relationship of Theory of Planned Behavior constructs (TPB; attitudes, subjective norms, and perceived behavioral control [PBC]) to nonsmoking intention among college students. Participants: Participants were 619 students at a Southeastern US university (69.8% female, 70.8% ≤ age 21, and 73.5% white). Methods: Students were recruited by email in March 2013 to participate in an online TPB-based questionnaire. Results: Future-oriented attitudes and PBC predicted higher nonsmoking intention; subjective norms did not. Moderator analyses indicated injunctive norms were more influential for occasional smokers and PBC was less influential. Conclusions: Findings suggest TPB is useful in predicting nonsmoking intention, but differentially for nonsmokers and occasional smokers. Future work should consider the health-related utility of future-oriented attitudes toward nonhealth domains and the differing beliefs of occasional smokers.
