Individual differences in the "Greek effect" on risky drinking: the role of self-consciousness.

Although the environmental influence of Greek affiliation on drinking has been established, little is known about intrapersonal characteristics that make individuals susceptible to this influence. Self-consciousness (attending to one's self) was hypothesized to represent dispositional vulnerability to environmental influence. The potential moderating effect of self-consciousness on the relation between Greek involvement and drinking was examined longitudinally among college students (N = 319).
