Neuroimaging of Instrumental Learning Networks in Adolescent Cannabis Use Treatment
Indiana University
Summary
This study is testing whether brain activity related to learning can help predict how well teens respond to a treatment program designed to reduce cannabis use. Teens ages 14-17 will complete a brain scan and then take part in 10 weekly virtual sessions where they report cannabis use and complete drug tests at home. Participants can earn prizes for staying cannabis-free.
Description
This is a 13-week clinical trial to examine whether success during contingency management treatment for cannabis use is associated with baseline functioning of instrumental learning neuro-circuitries. The investigators propose to recruit N=80 youths ages 14-17 with varying levels of cannabis use. Following phone prescreening, participants will undergo informed consent/assent and eligibility assessment with an in-person visit. Participants who are eligible will undergo a functional magnetic resonance imaging (fMRI) scan where participants will perform an instrumental learning task during a seco…
