Low levels of end-tidal partial pressure of carbon dioxide (pCO(2)) the amount of carbon dioxide measured from expired air are commonly found in individuals with anxiety disorders but have not been examined as predictors of outcome from anxiety treatment. The current study examined pretreatment baseline pCO(2) as a predictor of outcome from cognitive behavioral therapy (CBT) and acceptance and commitment therapy (ACT) for anxiety disorders. Sixty-one individuals with a Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) defined principal anxiety disorder diagnosis completed 12 sessions of either CBT or ACT. Baseline pCO(2) was measured prior to entering treatment. Self-reported anxiety symptoms and quality of life were assessed at pre-treatment, post-treatment, and 6- and 12-month follow-up from baseline. Low baseline pCO(2) was associated with higher anxiety symptoms and lower quality of life across follow-up timepoints, above and beyond baseline symptom severity. These results suggest that low baseline pCO(2) predicts poorer outcome from CBT and ACT for anxiety and may warrant treatment that directly addresses respiratory dysregulation.
