Although research has demonstrated an association between certain types of
explanations for peer-group illicit consumption and self-reported intention
s to consume drugs and alcohol in response to peer influence, the mechanism
s underlying these relationships have nor been well studied. The results of
two studies support predictions that group attractiveness mediates the eff
ects of attributions regarding peer-group illicit consumption on intentions
to conform. Normative attributions for group substance abuse were associat
ed with reduced group attractiveness. The authors discuss the implications
of these findings for further research and for the design and implementatio
n of effective intervention programs.
