Study Background Help our researchers learn to predict responsiveness to cognitive behavioral therapy. Anxiety-, obsessive-compulsive, and trauma- and stressor-related disorders reflect a significant public health problem. These disorders are usually treated with cognitive behavioral therapy (CBT), but this doesn't work for all patients. We want to identify and test a biomarker that may help predict whether patients will respond to CBT. This study is designed to evaluate the predictive power of a novel biomarker based on a CO2 breathing challenge. We will assess physical and emotional reactivity to two breathing exercises completed prior to a 12-week course of CBT. Then, we will determine how such reactivity relates to treatment outcomes in individuals with several forms of anxiety-related problems. The 12 sessions of exposure-based CBT are offered free of charge. Your participation in this study may lead to better treatment approaches for with anxiety- and fear-related disorders.
