Overcontrol and neural response to errors in pediatric anxiety disorders

Area of Science:

• Neuroscience
• Child Psychology
• Psychiatry

Background:

• Pediatric anxiety disorders are common and influenced by multiple risk factors.
• Overcontrol, characterized by perfectionism and performance monitoring, is one such factor.
• Understanding the neural basis of overcontrol in pediatric anxiety is crucial for intervention.

Purpose of the Study:

• To investigate the role of overcontrol in pediatric anxiety disorders.
• To determine if overcontrol explains altered brain responses to errors in anxious children.
• To examine the relationship between overcontrol, anxiety severity, and neural error processing.

Main Methods:

• Parent-reported overcontrol scores were collected from children (ages 8-12) with and without anxiety disorders.
• Functional magnetic resonance imaging (fMRI) was used to assess neural responses to errors.
• Statistical analyses controlled for comorbid depression and ADHD.

Main Results:

• Children with anxiety disorders exhibited significantly higher levels of overcontrol.
• Overcontrol was strongly associated with anxiety symptom severity, independent of other conditions.
• Elevated overcontrol correlated with reduced neural activity in the dorsal anterior cingulate cortex (dACC) and insula during error processing.

Conclusions:

• Overcontrol is a significant characteristic of pediatric anxiety disorders.
• Overcontrol is linked to aberrant neural responses to errors, particularly in the dACC and insula.
• Targeting overcontrol may offer a promising avenue for early intervention in pediatric anxiety.
