A series of linear mixed-effect models examined trajectories of non-religious sipping at baseline (ages 9-10) and self-reported impulsivity (UPPS-P) and task-based inhibitory control (Flanker task) over time as predictors of past year drinks and problematic alcohol use by ages 15-16. Predictors were run as separate models and a full model with all predictors together. Models were nested within the participant and study site. Interactions with age (to measure change over time from Baseline to Year 6) were included. Corrections for multiple comparisons were employed.<\/jats:p>\n                <\/jats:sec>\n                <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>\n                    In individual models, four impulsivity interactions were significant: (1) negative urgency*age (\u03b2=.04, FDR-\n                    <jats:italic>p<\/jats:italic>\n                    &lt;.001), (2) positive urgency*age (\u03b2=.04, FDR-\n                    <jats:italic>p<\/jats:italic>\n                    &lt;.001), (3) lack of planning*age (\u03b2=.04, FDR-\n                    <jats:italic>p<\/jats:italic>\n                    &lt;.001), and (4) sensation seeking*age (\u03b2=.04, FDR-\n                    <jats:italic>p<\/jats:italic>\n                    &lt;.001), suggesting that as age increases, the relationship between impulsivity and alcohol use strengthens.

Our results found a negative interaction between negative urgency and age on problematic use, potentially indicating negative urgency as a phenotype of vulnerability to experiencing alcohol related problems at younger ages. Findings indicate the importance of understanding facets of impulsivity in the context of adolescent alcohol use for prevention and intervention efforts.<\/jats:p>\n
