Parent and friend influences may differentially promote or deter adolescent smoking at discrete stages. Drawing from national (Add Health) data, a partial proportional odds ordinal regression model was utilized to examine the multivariate influence of parent and friend variables and their interactions on transitions across smoking stages (Never Smokers, Experimenters, Intermittent, Regular/Established) separately for mother-child pairs (N = 15,983) and father-child pairs (N = 1,142). Friend smoking status was by far the strongest predictor across smoking stages. Gender differences indicated males with one or more daily smoking friends are at higher risk for regular smoking relative to females. Fathers' smoking status had a direct effect on teen smoking across all stages, whereas mothers' smoking was significant in influencing which stage of smoking teens exhibited. Moreover, maternal smoking status had an indirect effect by moderating the association between teen smoking and the closeness of the mother-teen relationship. Mothers who smoke were found to have a stronger impact on the transition to regular smoking compared to mothers who do not smoke regardless of the number of smoking friends the teen reports. Results have implications for stage-matched and family-based prevention and intervention programs.
