Recruiting now · Not applicable

Conditions studied: Obsessive-Compulsive Disorder

In brief

This randomized controlled trial aims to evaluate the effects of digital mindfulness-based therapy in people with obsessive-compulsive disorder and to explore its possible psychological and neurophysiological mechanisms. A total of 150 participants with a primary diagnosis of obsessive-compulsive disorder will be randomly assigned in a 1:1:1 ratio to one of three groups: digital mindfulness-based therapy, routine pharmacological treatment, or digital mindfulness-based therapy combined with routine pharmacological treatment. The digital mindfulness-based therapy program will last for 6 weeks and will be delivered through a mobile mini-program using structured video and audio lessons, guided mindfulness practices, supervised weekly learning, and home practice. Participants in the pharmacological treatment group will receive routine pharmacological treatment for obsessive-compulsive disorder, and participants in the combined group will receive both interventions. Changes in obsessive-compulsive symptoms, mindfulness, emotional symptoms, and other psychological outcomes will be assessed during treatment and follow-up. Heart rate variability will be assessed at baseline and weekly during the 6-week intervention. Electroencephalography will be assessed at baseline, at the end of the 6-week intervention, and at the 3-month and 6-month follow-up assessments to explore neurophysiological changes associated with treatment.
