College students' hookup motivations as predictors of the positivity and negativity of their most recent hookup experience.

Objective: Previous research has found that college students experience both positive and negative outcomes after a hookup. The present study examined the role that hookup motives and sex play in determining the overall positivity and negativity of the experience. Participants: College students (N = 156) completed an online survey about their most recent hookup. Method: The survey assessed hookup motivations and outcomes. Results: Lower coping motives and higher social-sexual, relationship-seeking, and enhancement motives predicted more positive outcomes. Higher coping motives and lower social-sexual, conformity, and enhancement motives predicted more negative outcomes. For men, positive outcomes were correlated with weaker enhancement motives, while negative outcomes were correlated with more enhancement motives. For women, higher levels of positive outcomes were positively correlated with enhancement, social-sexual, and relationship-seeking motives, while negative outcomes were negatively correlated with social-sexual, enhancement, and coping motives. Conclusions: The results of this study have implications for risk prevention and future research.

Adolescent Marijuana Dependence: The Role of Social Bonds and Social Learning Theory.

Using the 2017 National Survey of Drug Use and Health (NSDUH) data, this research examines the extent to which social bonds and social learning theory predict adolescent marijuana dependence. Full information maximum likelihood (FIML) for logistic regression analyses were conducted in four models to test the competing theories. The results revealed partial support for both theories, such that adolescents with stronger parental bonds and negative definitions of substance use were less likely to be dependent on marijuana, while adolescents who associated with substance using peers were more likely to be dependent on marijuana. The multi-theoretical model suggested that only the social learning theory concepts of differential association and negative definitions were significant theoretical predictors of adolescent marijuana dependence. Additional analyses revealed that first using marijuana at 14 or 15 years old was also significantly related to adolescent marijuana dependence. Implications for future research and risk prevention programs are discussed.
