Identifying early risk factors for the development of social anxiety symptoms has important translational implications. Accurately identifying which children are at the highest risk is of critical importance, especially if we can identify risk early in development. We examined continued risk for social anxiety symptoms at the transition to adolescence in a community sample of children (n = 112) observed for high fearfulness at age 2 and tracked for social anxiety symptoms from preschool through age 6. In our previous studies, we found that a pattern of dysregulated fear (DF), characterized by high fear in low threat contexts, predicted social anxiety symptoms at ages 3, 4, 5 and 6 years across two samples. In the current study, we re-evaluated these children at 11-13 years of age using parent- and child reports of social anxiety symptoms, parental monitoring, and peer relationship quality. DF uniquely predicted adolescents' social anxiety symptoms above and beyond the prediction made by more proximal measures of behavioral (e.g., kindergarten social withdrawal) and concurrent environmental risk factors (e.g., parental monitoring, peer relationships). Implications for early detection, prevention and intervention are discussed. [This paper was published in "Development and Psychopathology" v33 n1 p252-263 2021.]
