Protective and Risky Social Network Factors for Drinking During the Transition From High School to College.

OBJECTIVE

The transition from high school to college is a unique developmental period to examine the relationship between social networks and alcohol use, because during this transition, students enter new environments and alcohol use becomes more pervasive. The aim of this study was to examine the extent to which personal social networks change during this transition and to examine how changes in the composition of networks are related to alcohol use.

METHOD

Participants (N = 374, 57.8% female) reported on their alcohol use and provided information about individuals in their social network before and immediately after their first year of college. These network members were matched across the two observations and were classified as either carryover (i.e., named at both assessments), dropped (i.e., named at only the first assessment), or added (i.e., named at only the second assessment).

RESULTS

We found robust turnover, such that only 22% of network members were retained from the first observation to the second. Furthermore, heavy drinking in high school was associated with retaining more friends during the transition to college, but once in college, adding more heavy drinkers as friends was associated with the greatest alcohol risk.

CONCLUSIONS

These findings show how changes in the composition of the social network influence an individual's alcohol use during the transition to college. Results from this study could be used to improve interventions that address the composition of the social network as a whole, as well as the characteristics of each individual in their social network.
