It manifests itself in avoidance of social situations, difficulties forming relationships and an overall increased impairment in social functioning. In adulthood, individuals with SAD report an overall poorer quality of life. Intolerance of uncertainty (IU) and coping strategies have been associated with SAD in recent literature. However, information on this subject is scarce in adolescents. This study investigates the relationship between IU and traits of social anxiety (SA) in adolescents, incorporating age as a moderating variable and adaptive and maladaptive coping strategies as a mediating variable. Data on SA traits, IU and coping strategies was collected within a larger study from a non-clinical sample using questionnaires. This study included 233 participants (Mage = 18.6, SD = 3.3) of which 81% were female. Results of this study show a positive relationship between IU and SA traits. This positive relationship weakens with age during adolescence. Additionally, maladaptive coping strategies mediate the relationship between SA and IU, strengthening this relationship. These findings indicate IU, age and coping are important factors to be considered in relation to the development and maintenance of SAD. Future research should continue on this subject to provide additional practical implications for the prevention and treatment of SADShow less
