Psychosocial factors in adolescent nicotine dependence symptoms: a sample of high school juniors who smoke daily.

Cross-sectionally examined seven theory-guided psychosocial factors associated with nicotine dependence symptoms in a representative self-report survey of 794 Washington State high school junior daily smokers (93% participation). Outcomes were four nicotine dependence symptoms. Results showed that low self-efficacy for quitting smoking and being around adults who smoke were associated with a 3.48-10.35 and a 1.47-1.77 times higher odds, respectively, of each of the four nicotine dependence symptoms. These results, needing replication in a longitudinal study, suggest that interventions designed to enhance self-efficacy to quit smoking and counter adult smoking influences might reduce adolescent nicotine dependence.
