Social anxiety is related to various comorbidities, with the most common being elevated alcohol use (Bolton et al., 2006). The symptom profile of this unique subset of cases with social anxiety and comorbid alcohol use is more complex and experiences higher resistance to treatment (Buckner et al., 2008). Both social anxiety and alcohol use emerge during the adolescent developmental period, and yet there remains a gap in the understanding of potential developmental risk factors associated with the onset and maintenance of these co-occurring symptoms. The current study investigated trait impulsivity, cognitive flexibility, and risk-seeking during adolescence and associations with alcohol use and social anxiety in young adulthood. Participants included 167 adolescents (Mage = 14.07 years, SD = 0.54; 52.7% male) followed to young adulthood (Mage = 22.30, SD = 0.69). Growth mixture models indicated that high levels of risk-seeking during adolescence predicted social anxiety in young adulthood. Contrary to hypotheses, high (compared to moderate) risk-seeking participants had lower alcohol use. Longitudinal patterns of high attentional impulsivity during adolescence into young adulthood predicated later social anxiety, whereas non-planning and motor impulsivity did not. Linear regression analyses indicated that lower cognitive flexibility during early adolescence was associated with social anxiety and alcohol use in young adulthood. Finally, moderation models suggested that global trait impulsivity was not a significant moderator of the relation between alcohol use during adolescence and social anxiety in young adulthood. This is the first work to evaluate these developmental risk-factors in relation to comorbid social anxiety and alcohol use, and has important implications for bolstering therapeutic interventions, especially for those with elevated impulsivity. / Doctor of Philosophy / Some socially anxious young adults have more difficulties with alcohol use compared to their peers. The combination of social anxiety and elevated alcohol use can lead to challenges in various aspects of life, such as school, work, and social functioning. Previous literature in the field suggests that both social anxiety and alcohol use emerge during early adolescence (ages 13-14); however, risk-factors during this important developmental period are still being explored. This dissertation evaluated the following possible risk-factors during adolescence that may be associated with the later development of social anxiety and alcohol use: trait impulsivity, cognitive flexibility, and risk-seeking. These risk-factors were explored using a dataset collected in Virginia that followed 167 adolescents over an eight-year period. Results indicated that youth with higher risk-seeking and attentional impulsivity during adolescence (ages 13-21) had significant social anxiety symptoms once they reached young adulthood (ages 22-23). Additionally, lower cognitive flexibility during ages 13-14 was associated with higher social anxiety and alcohol use in young adulthood. This is the first work to evaluate these risk-factors in relation to social anxiety and alcohol use, and has important implications for interventions, especially for those who have increased impulsivity and risk-seeking behaviors.
