| Abstract | Individuals are embedded in social contexts -- their cognitions, attitudes, resources, and normative references are meaningful to the extent that they define individuals relative to others. Yet, statistical models are routinely applied to behavioral theories, which assume that individuals act independently from one another. Even day-to-day decisions about private activities require cognitive pathways that depend on social meanings and contexts. Implicit cognitions, characterized by being non-conscious and automatic, are stored in memory with physical and social information. Evidence suggests that implicit attitudes can be communicated and spread through social exchanges, and can influence behaviors and drive social structures.; Social network analysis (SNA) is a set of tools and concepts that assess how relationships between people influence their behaviors (rather than teasing out interdependence as a nuisance). A relatively new area of SNA allows statistical inference about behavioral and network evolution using stochastic actor-oriented modeling. In these dissertation studies, the role of classroom friendships on alcohol and marijuana implicit cognitions and behaviors are examined by regression and SNA techniques.; Data are from an evidence-based drug intervention delivered to High school students over 3-months. Classes were randomly assigned to either the: standard program, (led by health educators), experimental program, (facilitated by peer leaders), or control condition (no intervention). Regression findings show that individuals adopt their friends' behaviors and cognitions regardless of program condition. Network findings show that in the standard condition, friends' alcohol behaviors influenced one’s own behaviors, and there was a preference for alcohol using friends. In the experimental condition, findings show preferences for friends who are non-drinkers and who have similar alcohol behaviors, and there was an overall reduction in alcohol cognitions. An explanation for this may be that using existing social relationships to disseminate educational material facilitates gradual shifts in social norms towards healthy alternatives to alcohol and marijuana use.; Interventions that target both (overt) behavioral and implicit cognitive changes at both the individual and group levels may be more effective at creating a cultural setting that supports healthy behaviors. Harnessing the spread of unconscious cognitive tendencies through friendship structures may be an effective strategy for creating behavioral change. |
