Abstract
BACKGROUND: In two studies, the present research examined whether being high in both social anxiety and alcohol use disorder symptoms is associated with a comorbid interpretation and expectancy bias that reflects their bidirectional relationship. DESIGN: Cross-sectional, quantitative surveys. METHODS: Measures of social anxiety and alcohol use disorder symptoms, as well as an interpretation and expectancy bias task assessing biases for social anxiety, drinking, and comorbid social anxiety and drinking. RESULTS: In Study 1 (N = 447), individuals high (vs. low) in social anxiety had stronger social threat bias and individuals high (vs. low) in alcohol use disorder symptoms had stronger drinking bias. Those high in both social anxiety and alcohol use disorder symptoms endorsed interpretations and expectancies linking social interaction with alcohol use. Comorbid bias predicted membership into the high social anxiety/drinking group, even after taking into account single-disorder biases. In Study 2 (N = 325), alcohol use disorder symptoms predicted drinking bias and social anxiety symptoms predicted social anxiety bias. Alcohol use disorder symptoms, social anxiety symptoms, and their interaction predicted comorbid interpretation and expectancy bias. CONCLUSION: Results indicate unique cognitive vulnerability markers for persons with comorbid social anxiety and alcohol use disorder symptoms, which may improve detection and treatment of this serious comorbidity.
