Satterthwaite t-test for unequal variances was used; self-efficacy (NA) and self-efficacy (Soc) = participants confidence in abstaining from alcohol when experiencing negative emotions or when faced with high risk social situations, respectively. SocNet: pro-abst, and SocNet: pro-drk = number of pro-abstainers and pro-drinkers, respectively, that participants reported in their social network.
