The authors tested a mediation model in which childhood hostility and sociability were expected to influence the development of intentions to use alcohol in the future through the mediating mechanisms of developing attitudes and norms. Children in 1 st through 5 th grades (N = 1,049) from a Western Oregon community participated in a longitudinal study involving four annual assessments. Hostility and sociability were assessed by teachers= ratings at the first assessment, and attitudes, subjective norms and intentions were assessed by self-report at all four assessments. For both genders, latent growth modeling demonstrated that sociability predicted an increase in intentions to use alcohol over time, whereas hostility predicted initial levels of these intentions. These personality effects were mediated by the development of attitudes and subjective norms, supporting a model wherein childhood personality traits exert their influence on the development of intentions to use alcohol through the development of these more proximal cognitions.
KeywordsPersonality; children; alcohol intentions; attitudes; subjective norms Alcohol is a widely accepted and licit substance that children as young as 3 years old can recognize (Spiegler, 1983). Early use by children and adolescents is associated with adult alcohol abuse (Grant & Dawson, 1997;Newcomb & Bentler, 1988). Although there has been considerable research on contextual, family and peer influences (Andrews, Hops & Duncan, 1997;Andrews, Hops, Tildesley & Li, 2002;Brook, Whiteman, Nomura, Gordon, & Cohen, 1988;Duncan, Duncan, & Hops, 1994; Patterson, Reid, & Dishion, 1992), there has been less examination of the influence of young children's personality traits and cognitions on the development of alcohol use (Tarter, 1988;Tarter et al., 1999). In the present study, we examined whether the influence of two personality traits, hostility and sociability, on the development of intentions regarding future alcohol use was mediated by attitudes and subjective norms. Both traits were assessed by teacher's ratings. Hostility was defined as physical and relational aggression, and associating with misbehaving children; sociability was defined as a combination of social competence, energy, and popularity. This model was tested on a community sample of young children participating in an ongoing longitudinal study, the Oregon Youth Substance Use Project (OYSUP; Andrews, Tildesley, Hops, Duncan, & Severson, 2003;Severson, Andrews, & Walker, 2003).

E-mail: sarah@ori.org. . here are from the first four years of the project following children from the 1 st through the 5 th grade until they were in the 4 th through the 8 th grade. Although few children in 1 st through 8 th grades have experimented with alcohol, during this period they develop intentions regarding their future use of alcohol.
