Mindfulness-Based Intervention and Transcranial Direct Current Brain Stimulation to Reduce Heavy Drinking: Efficacy and Mechanisms of Change
In Brief
A clinical study evaluating Brain stimulation with mindfulness-based relapse prevention for Alcohol Drinking and 2 related conditions. Completed, enrolled 84 participants across 1 site.
Detailed Summary
Alcohol use disorder (AUD) impacts millions of Americans and is associated with significant behavioral, social, economic, medical, and neurobiological dysfunction, yet current behavioral treatments for AUD are only modestly effective. The proposed research will test the efficacy of a novel behavioral intervention, which combines brain stimulation with mindfulness-based relapse prevention, and is hypothesized to improve neural dysfunction and ultimately lead to large effect size reductions in heavy drinking among individuals with AUD. Given that mindfulness and brain stimulation are already available for "home use" there is great potential for the ultimate dissemination of the intervention on a large scale, which could have a significant impact on public health.
Study Details
Timeline
Interventions
Participants will participate in weekly or twice weekly group mindfulness based relapse prevention (MBRP) + transcranial direct current stimulation (tDCS) intervention sessions for up to eight weeks. All participants will receive 8 two hour sessions of MBRP + tDCS, regardless of the group schedule. Subjects will receive 30 minutes of either active or sham tDCS stimulation, depending on their group assignment. After tDCS, sessions will include discussions of mindfulness as a means of coping with craving, cognitions, and emotions, role play exercises, and mindfulness practice.
