Social anxiety and age are associated with neural response to social evaluation during adolescence.

Adolescence is a sensitive period for the development of adaptive social behaviors and social anxiety, possibly due to aspects of brain development. However, research is needed to examine interactions among age, social anxiety, and social dynamics previously shown to influence neural responding. The current functional magnetic resonance imaging (fMRI) study examines brain function in 8-18 year-olds with varying levels of social anxiety. Interactions are examined among age, social anxiety, and two key task factors: valence and predictability of social interactions. Results demonstrate age, social anxiety severity, and each of the two key task-based factors interact to predict neural response in the caudate, middle and superior temporal gyri. In particular, among adolescents less-than 13 years of age, higher social anxiety predicted greater responding to unpredictable negative evaluations. However, in this same age group, the opposite pattern emerged during receipt of unpredictable positive evaluations, with less neural response in more anxious youth. Adolescents aged 13 and older overall showed less robust effects. We discuss these findings in terms of age- and anxiety-related differences in socioemotional processing.

Discriminant validity, diagnostic utility, and parent-child agreement on the Screen for Child Anxiety Related Emotional Disorders (SCARED) in treatment- and non-treatment-seeking youth.

The Screen for Child Anxiety and Related Emotional Disorder (SCARED) may be differentially sensitive to detecting specific or comorbid anxiety diagnoses in treatment-seeking and non-treatment-seeking youth. We assessed the SCARED's discriminant validity, diagnostic utility, and informant agreement using parent- and self-report from healthy and treatment-seeking anxious youth (Study 1, N=585) and from non-treatment-seeking anxious youth (Study 2, N=331) diagnosed with generalized anxiety disorder (GAD), social anxiety disorder (SAD), or comorbid GAD+SAD. Among treatment-seeking youth, the SCARED showed good diagnostic utility and specificity, differentiating healthy, comorbid, and non-comorbid anxious youth. Child-parent agreement was modest: healthy child self-reports were higher than parent-reports whereas anxious child self-reports were similar or lower than parent-reports. Less consistent results emerged for diagnostic utility, specificity, and informant agreement among non-treatment-seeking youth. Given the number of non-treatment seeking anxious youth (N=33), generalizability of these findings may be limited. Together, results suggest informants may provide distinct information about children's anxiety symptoms.
