Experimental Test of Facebook Social Drinking Norms on Adolescent Alcohol Use

Completed · Not applicable

Conditions studied: Feedback, Psychological, Underage Alcohol Use, Risk-Taking

In brief

The proposed research will be the first study to focus on experimentally manipulating both injunctive and descriptive norms on social networking sites in order to elucidate the relationship between alcohol and abstainer displays on social networking sites and subsequent alcohol cognitions, use, and related negative consequences. Based on literature focusing on developmentally appropriate health models for adolescents, the Prototype Willingness Model (PWM) assumes that health-risk behaviors occur either when individuals have developed intentions to engage in a risk behavior (and these intentions vary as a function of attitudes and perceived injunctive norms) or through willingness to engage in risks (which varies as a function of perceived vulnerability to negative consequences, perceived descriptive norms , and prototypes). To fully understand the relationships between alcohol abstaining displays on social networking sites, we will examine 1) the role of descriptive and injunctive abstainer and user norms, when experimentally manipulated with SNS profiles, on willingness and intentions, subsequent alcohol use and related negative consequences among adolescents (age 1 5-20) 2) whether intentions and willingness mediate the relation between our experimental manipulation and subsequent alcohol use and negative consequences and whether 3) individual differences in social influence moderate the effect of the experimental manipulation on intentions, willingness, alcohol use, and negative consequences. We will test these aims by recruiting a community sample of adolescents (N = 300), living in the greater Seattle metropolitan area. Participants will complete a web-based baseline assessment and participate in an in-person experimental manipulation in which they are either assigned to see same-sex social networking site profiles of alcohol abstainers, abstainers +users, or a control condition where neither user or abstainer information will be provided. Immediately after the manipulation, participants will answer a series of questions about the profiles they just viewed and their alcohol-related cognitions. Participants will also complete a one-month in person follow up assessment to test for impacts on intentions, willingness, alcohol use, and related negative consequences. Additionally, individual differences in social influence will be examined as possible moderators o f the relationship between SNS-portrayed norms and our primary outcomes. This study is both significant and innovative in that it uses a theoretical perspective to experimentally test the impact of alcohol content, in particular abstainer norms, on Facebook on adolescent alcohol use and related cognitions. The results have the potential to inform preventative interventions while addressing NIH priorities.
