Friend Selection and Influence Effects for First Heavy Drinking Episode in Adolescence.

ABSTRACT: OBJECTIVE:Heavy alcohol consumption has both immediate and longer-term risks for adolescents. Using a dynamic network modeling approach, this study investigated the role of adult supervision and affiliation with heavy drinking friends in predicting the risk of a first heavy drinking episode in a community sample of adolescents. METHOD:Two cohorts of ninth grade youth (n = 1,220, 48% male) from seven communities were surveyed three times over the course of the school year (fall, winter, and spring), each time assessing their friendship networks, whether they had ever experienced a heavy drinking episode, frequency of heavy drinking over the past month, and the amount of unsupervised time spent with each of their friends over the past month. RESULTS:Participants were more likely to form friendships with classmates with similar recent heavy drinking behavior, but similarity on adult supervision of time spent with friends had no effect on friendship selection. A negative interaction was observed between these two similarity effects, implying that they were antisynergistic. Risk for a first heavy drinking episode was greater for youth with friends who had experienced such an episode already. This effect was no stronger if these friends had more such episodes in the previous 30 days but was marginally stronger if the friends reported less adult supervision. CONCLUSIONS:Heavy drinking-related friendships increase the risk of a first heavy drinking episode. Adult supervision of time spent with friends may reduce this risk. Results support interventions that target the spread of heavy drinking through adolescent social ecosystems, in addition to targeting the most at-risk individuals.

Project description:BackgroundDual systems theories suggest that greater imbalance between higher reward sensitivity and lower cognitive control across adolescence conveys risk for behaviors such as heavy episodic drinking (HED). Prior research demonstrated that psychological analogues of these systems, sensation seeking and premeditation, change from childhood through emerging adulthood, and each has been independently linked with HED. However, few studies have assessed whether change over time in these developing analogues is prospectively associated with HED. Moreover, we know of no research that has shown whether within-person differences between higher sensation seeking and relatively lower premeditation across the adolescent period predict HED in emerging adulthood.MethodsProspective data from the National Consortium on Alcohol and NeuroDevelopment in Adolescence study (n = 715) were used to examine the association of sensation seeking and premeditation with HED among adolescents ages 16 to 20 years. We used novel applications of latent difference score modeling and growth curve analysis to test whether increasing sensation seeking, premeditation, and their imbalance over time are associated with HED across the study period, and whether these associations differed by sex.ResultsWhereas premeditation increased linearly from adolescence through emerging adulthood across sexes, males reported growth and females reported decline in sensation seeking. Sensation seeking in adolescence (and not premeditation) was associated with higher levels of HED by emerging adulthood. Importantly, greater imbalance between sensation seeking and premeditation was associated with higher levels of HED by emerging adulthood though we note that variability capturing this imbalance correlated highly (r = 0.86) with baseline levels of sensation seeking.ConclusionsDevelopmental imbalance between higher sensation seeking and lower premeditation in late adolescence may be a risk factor for greater HED in emerging adulthood.
