  • Title: A comparison of the mediational properties of four adolescent smoking expectancy measures.
    Author: Hine DW, McKenzie-Richer A, Lewko J, Tilleczek K, Perreault L.
    Journal: Psychol Addict Behav; 2002 Sep; 16(3):187-95. PubMed ID: 12236453.
    Abstract:
    This prospective study compared the ability of 4 smoking expectancy measures to mediate the influence of peer, parent, and current smoking on adolescents' cigarette use 3 months later. No evidence for mediation was found when expectancies were operationalized as unidimensional subjective expected utility (SEU), multidimensional SEU, or unidimensional SEU decomposed into probability and desirability main effects and their interaction. Evidence for partial mediation was found for the decomposed multidimensional SEU measure. The results suggest that (a) peer and current cigarette use may influence future smoking indirectly through adolescents' probability estimates that smoking will control negative emotions and (b) the relationship between current and future smoking also may be mediated by adolescents' beliefs about the desirability of weight control.
