Article: Trucco, E. M., Colder, C. R., & Wieczorek, W. F. (2011). Vulnerability to peer influence: A moderated mediation study of early adolescent alcohol use initiation. Addictive Behaviors, 36, 729-736. Reason of the Study: * Early alcohol association is strongly associated with frequent binge drinking in college. Identifying risk factors associate with alcohol use in early adolescence may help develop effective prevention programs. What is new from the Study: * Test a mediational pathway: Perceived peer approval and use of alcohol would mediate the the association between peer delinquency and initiation of alcohol use. * Parenting behavior is tested as a moderator for the proposed mediational pathway. Hypothesis: * Perceived peer approval and use of alcohol would mediate the relationship between perceived peer delinquency and initiation of alcohol use one year later. * The influence of peers on alcohol use initiation would be relatively weak at high levels of both parental control and parental warmth. About the study: * non-experimental ->prospective longitudinal study, multiple regression analysis * investigating how predictors influence criterion in the same group of adolescents across different time periods * selected a good test for their study Participants of the study: * 371 11–13 year-old adolescents from New York (55.5% female, 83.0% Caucasian), selected from the another longitudinal study, recruitment involved a random-digit-dial sample * second assessment occurred approximately one year following the initial interview. The attrition rate was 4% * sampling techniques are acceptable, but all from New York and were recruited from study, which may inflate self-reported delinquency and alcohol initiation Data Analysis: * Predictor Variable: Perceived peer delinquency * Mediating
