A Multilevel Study of Alcohol Consumption in Young Adults: Self-E cacy, Peers’ Motivations and Protective Strategies

Abstract

In both developing and underdeveloped countries there has been a worrying increase in the number of young people drinking alcohol; this public health problem warrants more research. This multilevel study analyzed the influence of drinking refusal self-e cacy, peers’ motivation, and protective behavioral strategies as predictors of alcohol consumption in a sample of 261 young people arranged into 52 social groups (peers who regularly shared leisure activities). A series of questionnaires were administered individually to evaluate beliefs and behaviors related to alcohol consumption at both individual level (drinking refusal self-e cacy) and peer level (enhancement motivation and protective behavioral strategies). The results showed that the individual variable (drinking refusal self-e cacy) predicted alcohol consumption behaviors. The multilevel design allowed us to evaluate the direct and moderated e ects of peers’ enhancement motivation and protective behavioral strategies on the relationship between self-e cacy and drinking behavior. These results show the importance of developing cognitive, behavioral, and educational intervention programs to increase young people and university students’ confidence and ability to use protective strategies, in order to reduce alcohol use
