Marijuana is the second most commonly used substance in the US. A growing literature suggests that socially anxious individuals use marijuana to manage their symptoms in social situations, which may explain why they are also more likely to experience problems. Unfortunately, the majority of the literature is based on research conducted with adult samples or the co-occurrence of diagnoses in adolescent samples. The proposed study sought to test the link between social anxiety (SA) and proxies for ‘real-time' marijuana use behaviors (i.e., use willingness) as well as use-related problems among adolescents. Participants were 69 adolescents (15-17; 55% female) recruited from the community reporting any lifetime marijuana use. Participants were randomly assigned to a novel social rejection or neutral laboratory task and completed measures of SA, marijuana use frequency, and related problems. Consistent with adult findings, main effects of SA and experimental condition on marijuana use willingness were expected to be qualified by an interaction in which the greatest marijuana use willingness would occur among high SA youth post-rejection (H1), SA would be positively related to marijuana use problems (H2), and among adolescents in the rejection condition, marijuana use willingness would be positively correlated with use problems (H3). Only H2 was supported, highlighting areas of convergence and divergence in the role of SA and social stress on marijuana outcomes. These data stand to improve the scientific knowledge on the relative roles of SA and social stress on marijuana use within an understudied, high-risk population and help inform future intervention efforts.

The aim of this study was to explore temperament, psychopathology and quality of life (QOL) in adolescents born at extremely low birth weight (ELBW), i.e., < 1000g. ELBW adolescents (N = 15) completed the Revised Cheek and Buss Scale and Mini International Neuropsychiatric Interview 5.0.0 (M.I.N.I.), while their legal guardians completed a biographical questionnaire and the Short Form 12 version 2. The median age of the sample was 13 SD = 2.526 years (60% male) and all participants spoke English. ELBW adolescents with social phobia (n = 6) were more shy (p = .041) and had poorer mental health-related QOL (p = .041) than those without such symptoms. The results suggest that ELBW could be a predisposing factor for increased shyness and psychological disorders including social phobia. Planning of interventions for ELBW individuals should therefore include strategies to prevent or mitigate the effects of these factors in adolescence / Psychology / M.A. (Clinical Psychology)
