Respiratory Training vs Interoceptive Exposure in the Treatment of Transdiagnostic Pathological Anxiety

Description

Purpose of the Research: The primary aim of the proposed study is to conduct a randomized parallel-group 3-arm clinical trial comparing two mechanistically distinct interventions for pathological anxiety - (1) Interoceptive Exposure (IE) utilizing graduated exposure to somatic cues (respiratory, cardiac, vestibular) with the primary aim of reducing fear responding to the presence of interoceptive perturbations; (2) Capnometry-Guided Respiratory Intervention (CGRI) aimed at raising end-tidal CO2 levels thereby lowering hyperventilation-induced respiratory alkalosis and its associated fear-eliciting somatic reactions; and (3) Psycho-education about anxiety and its effects (PsyEd), which will serve as a credible control comparator.
