Abstract

Many university students engage in risky alcohol consumption behaviour during their stay at university. So far, however, most studies have relied on cross-sectional surveys and paid little attention to the role of social ties. University students, however, are socially connected, so it is likely that their alcohol consumption behaviour is also connected. We hypothesized that university students' social positions within their networks are related to their drinking behaviour. We carried out a social network analysis within a whole network approach with undergraduates in two faculties (n = 487), those of Engineering and Psychology, in a Belgian university. All students filled out a questionnaire recording their drinking behaviour and their social ties (friendship, working with, partying with and room-mate). For each individual, indicators of centrality, social capital, and cross-gender relationships were computed. We found that being socially close to binge drinkers was associated with a higher frequency of binge drinking. The risk of binge drinking increased with centrality but decreased with social capital. Having cross-gender relationships decreased the risk of binge drinking. We found indications that the effect of centrality and gender on binge drinking depends on the composition of the network. We conclude that social position has important effects on risky drinking behaviour and that the composition of the network may affect these factors. Those developing health promotion strategies could investigate the benefits of targeting central individuals in order to prevent binge drinking among university students.
