Exposure-based cognitive behavioral therapy is an established treatment for anxiety disorders, yet individual responses vary considerably. Identifying specific mechanisms of change is therefore critical for optimizing treatment efficacy, and prior research has pointed to post-exposure positive emotions, particularly increases in pride, as predictive of better treatment outcomes. Building on this evidence, the present study investigates whether a brief intervention designed to enhance post-exposure pride (Expo+Pride) produces greater reductions in fear of public speaking compared to standard exposure therapy alone (Expo-TAU). The study employs a two-group, parallel, randomized superiority design and is conducted across multiple sites within the Exposure Therapy Consortium. Participants undergo two in-person exposure sessions incorporating a virtual reality-based public speaking task, with the Expo+Pride group receiving an additional pride-enhancing intervention. Ultimately, the study aims to clarify the role of pride as a mechanism of change in exposure therapy and to provide better treatment options for individuals suffering from anxiety disorders.
