The U.S. National Institute on Drug Abuse (NIDA), through the Drug Use and Addiction Research Programs (CFDA 93.279), awarded a $163,568 Project Grant to Brown University to conduct a multimodal study on the relationship between cannabis use, trauma, and self-regulatory cognitive processes. The study aims to examine how decision-making processes, such as reward motivation and inhibitory control, relate to cannabis use among young adults following a potentially traumatic event. The project will leverage methodological advantages of the parent study (R01DA054116), including the use of psychophysiological measurement, ecological momentary assessment, wearable biosensors, and longitudinal follow-ups. The study will recruit 70 participants from the parent project, add two baseline self-report measures, and implement two behavioral tasks to assess reward motivation and inhibitory control at two timepoints - 2 weeks and 6 months post-trauma. The researchers will use advanced computational modeling techniques to integrate physiological and behavioral data to evaluate the cognitive mechanisms underlying the relationship between traumatic stress reactivity and cannabis use. The award period is from January 1, 2025, to August 31, 2026.
