Social network drinking and adult alcohol involvement: a longitudinal exploration of the direction of influence.
Past research shows consistent associations between individuals' drinking patterns and the drinking patterns of their social network members. This association has usually been attributed to the influence of social networks on individual behavior. Recent studies concerning adolescent drinking behavior suggest that such associations may be due, in part, to selection effects in which individuals form social ties with those who have drinking habits similar to their own. The present study used longitudinal data and structural equation modeling to compare the selection and influence effects among a large representative sample of adults. Results suggested that both selection and influence affect the association between individual and network drinking patterns among adults, but that social selection effects are substantially stronger than social influence effects. A cross-lagged structural equation model with a normed fit index of .975, showed that the path indicating peer influence had a coefficient of .069 (P<.01), whereas the path indicating network selection had a coefficient of .193 (P<.01). Comparisons across age, race, sex, and marital status groups revealed similar results, with stronger selection than influence effects for all groups.
