title: Do interactions between personality and social-environmental factors explain smoking development in adolescence?
abstract: This study examined if the effects of peer smoking, family smoking, and parenting on smoking development during adolescence are moderated by personality characteristics of adolescents. Longitudinal data were obtained from 428 adolescents (aged M = 13.4, SD = .50) and their parents. Latent Growth Curve models assessed the development of smoking as a function of predictors and if effects of smoking-specific parenting and exposure to smoking were moderated by adolescents' Big Five personality dimensions. Findings revealed that having peers who smoked was associated with an increased likelihood of being a smoker at baseline. Further, significant interactions revealed that adolescents lower in agreeableness were more likely to be a smoker at baseline if they had an older sibling who smoked or if their parents engaged in frequent smoking-related discussions with them and that effective smoking-specific conversation was more strongly related to smoking at baseline among adolescents who were highly emotionally stable. No interactions predicted growth in smoking over time yet significant main effects showed that growth in smoking was associated with higher levels of extraversion, lower levels of emotional stability, and less effective parental smoking-specific communication. This study highlights the relevance of personality-target interventions and policy programs directed at parents and peers.
