Effects of age and subtype on emotional recognition in children with anxiety disorders: Implications for cognitive-behavioural therapy

Abstract

Objective: It remains unclear whether an anxiety diagnosis is associated with children's emotional recognition. We considered children's age and types of primary anxiety diagnosis, which have been neglected, to elucidate this relationship. Methods: Sixty-three referred children with anxiety disorder(s) and 59 volunteer children without anxiety disorder(s), aged between 6 and 11 years, were presented with animated characters, displaying a range of simple and complex emotions, for identification. Statistical analyses examined identification accuracy based on presence or absence of anxiety disorder, age, and types of primary diagnoses. Results: Children with anxiety disorder(s) as a group performed comparably to children without anxiety disorder(s) in identifying emotions (z = -0.72, P = 0.47). In both groups, accuracy for disgust increased significantly each year of age ([anxiety group] OR 2.6; 95% CI 1.6 to 4.3, P < 0.001, [control group] OR 2.1; 95% CI 1.3 to 3.3, P = 0.002). When primary anxiety types were considered, while controlling for age, children with separation anxiety disorder (SAD) showed deficits in overall emotional recognition, compared with children with other subtypes or without anxiety (P = 0.004). Further regression analyses showed that children with generalized anxiety disorder (GAD) presented significantly lower accuracy than children without anxiety disorder(s) at a young age, but the deficit disappeared with increased age. Conclusion: Children with anxiety disorder(s) as a group may not appear to be impaired in emotional recognition. However, when age and subtypes are considered, children with SAD and young children with GAD appear to have difficulty, compared with children without anxiety disorder(s).
