abstract
Adolescent tobacco use is influenced by intrapersonal (e.g., impulse control) and external factors, such as behaviors of friends and peers. The relationships of these factors to smokeless tobacco (ST) use are not yet fully understood. This is especially true as it pertains to the simultaneous examination of psychological and normative perceptions. Using constructs of the Biopsychosocial Model, this study investigates factors associated with lifetime ST use among middle and high school students. Data were analyzed from 938 Indiana middle and high school students. Binary sequential logistic regression was performed to examine the relationship of personal characteristics and psychosocial measures to adolescent lifetime ST use. Approximately 9 % reported having ever used ST, among which 78.6 % were male. Females and younger students were less likely to have used ST in their lifetime, whereas participants with a sibling smoker and those who compared their life to the lives of others were more likely to report lifetime ST usage. In the presence of psychological and normative variables, sex, age, and comparing one's life to others remained significant. Additionally, participants who perceived higher friend approval of substance use were significantly more likely to report lifetime ST use. Understanding the normative perceptions of adolescents may lend insight into the drivers of ST use adolescent subgroups and, which may enable community and school officials to tailor interventions to prevent ST initiation and promote cessation.
