A Pilot Study of Non-invasive Brain Stimulation to Boost the Efficacy of

Status Recruiting

Clinical Trial Summary

The goal of this small (n=75) proof-of-concept randomized clinical trial is to test the effects of transcranial alternating current stimulation (tACS) during motivational interviewing (MI) sessions with participants who drink at above the low-risk level. Participants will be randomized to receive either MI with active stimulation, MI with sham stimulation, or a delayed treatment group that receives MI with no stimulation. Measures will include brain imaging, alcohol use, cannabis use, risk-taking behavior, emotions, and others. Participants who are randomized to the delayed-treatment group will not receive brain imaging.

Clinical Trial Description

This proof-of-concept randomized clinical trial will recruit n=75 people with problematic levels of drinking who are considering treatment for their alcohol use. These participants will be randomized to one of three conditions: a condition that applies active tACS during an MI session (MI+tACS), a condition that applies sham stimulation during an MI session (MI+sham), or a waitlist control condition (MI-only). Only participants the MI+tACS and MI+sham conditions will be included in the brain imaging portion of the study. One month after their intervention session, all participants will report their use of alcohol in the prior 30 days via an online assessment battery. This will allow us to test the effects of tACS on within-session client speech and outcomes. Participants will have magnetoencephalography (MEG) scans including rest and an alcohol cue task to measure the acute effects of brain stimulation. Participants will also have MRI scans including structure and rest. The Motivational Interviewing Skill Code (MISC 2.5) and the CASAA Application for Coding Treatment Interactions (CACTI) will be used to assess counselor and participant speech in the recorded MI sessions and to ensure that sessions comply with the principles of MI. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
