Background: Family smoking environment and family management are associated with risk of teen smoking behaviors. However, less is known about whether these associations increase or decrease in strength across adolescence, and whether there are person-environment interactions. The current study examined 1) the age-varying main effects of family smoking and family management on adolescent daily smoking from ages 12-18 and tested 2) whether behavioral disinhibition and anxiety moderated these relationships.
Methods: Data were drawn from the Seattle Social Development Project (SSDP; N = 808), a longitudinal study examining prosocial and antisocial behavior. Analyses used time-varying effect modeling (TVEM), which tested the stability of the relationship between family smoking and family management and youth daily smoking across adolescence.
Results: Greater family smoking increased the likelihood of adolescent daily smoking, whereas greater family management reduced the likelihood of daily smoking. Significant interactions between family management and youth behavioral disinhibition and anxiety during early and mid-adolescence indicated that family management was more protective for adolescents with low (compared to high) behavioral disinhibition and anxiety. The effect of family smoking was not moderated by behavioral disinhibition or anxiety.
Conclusions: Family smoking and family management are key risk and protective factors that may be targeted for adolescent smoking prevention. Our interaction results for individual differences in behavioral disinhibition and anxiety suggest that certain types of youth may respond differently to family management practices. Findings also show periods during adolescence where family-centered preventive interventions could be optimally timed to prevent or reduce persistent adolescent smoking.
