The purpose of this study designed a randomized clinical trial is to determine the efficacy of an 8-week mindfulness-based cognitive therapy using neuroscience (NMBCT) to reduce anxiety or depressive symptoms among adult participants with anxiety and depression. The primary object is to assess the effectiveness of NMBCT to change in the structural or functional brain. A secondary objective is to reduce clinical symptom severity.
There are reports that mindfulness-based cognitive therapy (MBCT) techniques in patients with panic disorder or depression promote neuroplasticity changes in the brain, thereby restoring individual vulnerability to anxiety. This clinical study aims to develop a metacognitive task that improves existing MBCT as a new treatment that changes the function of anxiety or depression-specific neural circuits, and to explore neurological mechanisms and treatment-related factors.
This study was designed to enroll 64 participants, 32 in the NMBCT intervention and 32 in waitlist. This will allow 20% attrition and the Investigators anticipate 52 participants will complete the study. A sample size of 52 will achieve 80% power, given current effect size (cohen's d = 0.40, alpha = 0.05) estimates per aim.
Participants randomized to the NMBCT intervention or waitlist group will complete an 8-week NMBCT program conducted by a trained psychiatrist. The waitlist control group will maintain the blind for a treatment period from the baseline and then implement the NMBCT program on the NMBCT intervention group to those who agree.
Study data will be collected at 3 times for two groups: T1=1st week session (baseline); T2=8th week session; T3=6 months after baseline. All participants in the clinical study will undergo a total of two brain MRI tests within two weeks before and after visit 2 (T1, baseline) and visit 3 (T2, post-treatment, 8 weeks later).

| Mindfulness-based cognitive therapy using neuroscience (NMBCT) | Behavioral | Mindfulness-based cognitive therapy using neuroscience (NMBCT) is a standardized 8-week course taught by trained instructors. The NMBCT is a group therapy that takes place once a week for about 90 minutes per session. The program consists of mental education for each session, 2-3 mindfulness meditation practice, mindfulness practice in daily life, and about 30 minutes of daily home mindfulness meditation task. While participating in the program, the subjects will receive psychoeducation and various mindfulness meditation techniques (eating meditation, breathing meditation, sedentary meditation, viewing meditation, and listening meditation, etc.). |
