fMRI Evaluation of Cross-Commodity Temporal Discounting in Recreational Drug Users and Cocaine Users (H-27117)
The purpose of this non-medication-based outpatient study is to determine the differences in risky decision-making between individuals who do and do not use cocaine.
This study consists of two visits/sessions, each lasting approximately 2 to 3 hours. For Session 1, participants will visit the research unit at the Michael E. DeBakey VA Medical Center (MEDVAMC) in Houston, Texas, to complete a series of questionnaires about their personality, health history, decision-making, etc., followed by a short computer task. During the computer task, participants will be asked to make decisions in various hypothetical scenarios (e.g., choose between receiving money now vs. later). Participants that qualify to complete the study will return to the MEDVAMC for Session 2 approximately one week later. During Session 2, participants will transfer to nearby Baylor College of Medicine to have a functional magnetic resonance imaging (fMRI) scan taken of their brain while completing a computer task similar to that in Session 1. The scan is expected to last approximately 30 to 50 minutes. Upon study completion, participants will receive a CD containing images of their brain. (Note: Images will not be reviewed by a doctor and will not be used to find or rule out any medical problems. There will be no medical follow-up or consultation related to this study). Participants will be compensated.
