There is evidence for variability in the degree to which adolescents are susceptible to peer influence (Brown, Bakken, Ameringer, & Mahon, 2008). This suggests that it is important to consider potential moderators of peer influence, and this is the primary aim of the current study. We propose that a key construct from social information-processing models, namely social goals, may increase or decrease the influence of peers on intentions to use alcohol and cigarettes.
