Obessive-Compulsive Disorder (OCD) is frequently treatment-refractory and imposes a substantial burden on affected individuals. Although Exposure and Response Prevention (ERP) is widely regarded as the first-line intervention, its inherently distressing nature contributes to treatment refusal and premature dropout in a subset of patients. The present study aims to develop and validate a novel intervention, Mindfulness-Based Exposure Therapy (MBET).
In contrast to existing protocols that incorporate mindfulness as an adjunct to ERP and have yielded mixed or limited benefits, this study seeks a theoretically grounded integration of mindfulness and exposure-based principles. We hypothesize that mindfulness training improves emotion regulation, thereby producing a synergistic effect that enhances patients' capacity to engage in and complete exposure tasks.
From a clinical perspective, MBET is intended to offer a more tolerable and acceptable alternative to standard ERP, with the potential to improve treatment adherence and clinical outcomes among patients who experience traditional exposure procedures as excessively distressing.

mindfulness based exposure therapy
BehavioralMindfulness-Based Exposure Therapy (MBET) is a structured, 10-week group psychological intervention specifically designed for individuals with Obsessive-Compulsive Disorder (OCD). The program is delivered in weekly sessions, with each session lasting 3 hours. To ensure optimal group dynamics and personalized attention, each group consists of 6 to 8 patients and is facilitated by 1 to 2 trained therapists.To reinforce the skills acquired during the group meetings, participants are assigned daily homework at the end of each session, which requires 30 to 60 minutes of independent practice per day. At its core, the treatment process features a deep integration of mindfulness and Exposure and Response Prevention (ERP). Rather than treating these as separate components, MBET seamlessly embeds the core philosophies and practices of mindfulness directly into the ERP exercises, allowing patients to apply mindful awareness and acceptance while actively confronting their obsessional triggers.

Obsessive-compulsive symptoms improvement
The severity of OCD symptoms is assessed using the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS). Obsessive-compulsive symptoms improvement is reflected by Y-BOCS reduction rate.
