CHANGES IN EEG DURING COGNITIVE BEHAVIORAL THERAPY FOR TEST ANXIOUS STUDENTS

Published Date : 05-Dec-2014

Abstract

Coupling between EEG delta and beta oscillations is enhanced among anxious individuals during test situations. EEG coupling patterns associated with CBT have not yet been quantified in test anxious individuals. In this study, we used repeated measures design, in which 16 students from adolescent group with a principal diagnosis of test anxiety completed 3 week daily sessions of cognitive behavioral therapy and two EEG assessments: one at pretreatment, and one at post treatment. Treatment was associated with reductions in symptom severity across multiple measures and informants, as well as reductions in delta-beta coupling at rest. Moreover, the clinical group exhibited greater coupling at pretreatment than did post hoc control participants with low test anxiety. The EEG cross-frequency profiles in the clinical group normalized by the post treatment assessment. These findings provide evidence of concomitant improvement in neural and behavioral functioning among test anxious students undergoing cognitive behaviour therapy.
