Reductions in Anxiety are Associated with Decreased Expressive Suppression and Increased Cognitive Reappraisal After Cognitive-Behavioral Treatment: A Naturalistic Study in Youth.

Broad deficits in emotion regulation skills have been observed in children with anxiety-related disorders. These deficits typically improve during cognitive-behavioral therapy (CBT), but few studies have examined changes in expressive suppression and cognitive reappraisal in youth with anxiety disorders and/or obsessive-compulsive disorder (OCD) during CBT, especially in real-world settings. In a naturalistic treatment-seeking sample, 123 youth completed measures of anxiety, depression, and emotion regulation strategy use before and after 15 sessions of CBT. For anxious youth, anxiety and expressive suppression decreased over treatment, while cognitive reappraisal increased. Reductions in expressive suppression and increases in cognitive reappraisal were significantly associated with improvements in anxiety and remained significantly associated with post-treatment anxiety after accounting for baseline anxiety and depression. Changes in expressive suppression and cognitive reappraisal over the course of treatment were not found for youth with primary OCD. Thus, CBT improves emotion regulation abilities in anxious youth, and these improvements are associated with anxiety reduction; improvements in emotion regulation do not appear to drive changes in OCD symptoms. Further research is needed to determine whether changes in emotion regulation strategies mediate changes in anxiety among youth receiving CBT.
