“…Moreover, parents typically underestimate how often other parents communicate with their children about alcohol (Napper et al, 2014; Linkenbach, Perkins, & DeJong, 2003) and overestimate how approving other parents are of student drinking (LaBrie, Hummer, Lac, Ehret, & Kenney, 2011), beliefs which may lead them to communicate less often and convey a more approving attitude about alcohol use with their own children. In addition, parents have been shown to underestimate how often their own child consumes alcohol (LaBrie, Napper, & Hummer, 2014; Bylund, Imes, & Baxter, 2005), which may also cause them to be less motivated to initiate a conversation about drinking—viewing it as not needed for their students—than they would be if they held more accurate beliefs. Just as correcting students’ alcohol use norms leads to changes in their drinking-related attitudes and behaviors, social norms theory predicts that correcting parents’ alcohol communication norms would similarly influence them to adopt less approving attitudes and become more motivated to increase their alcohol-related messaging.…”
