Structural Racism, Reward Related Decision Making and Substance Use Risk
NCT06221839 · View on ClinicalTrials.gov ↗
Study Summary
The goal of this observational study, which has a pilot phase (R61) and a second, larger phase (R33), is to learn about the impact of indicators of structural racism (SR) on substance use risk in Puerto Rican adolescents living in the mainland US and in Puerto Rico. To do this, we will look at how indicators of SR relate to brain structure, brain function during reward-related choices, belief in a just world, and substance use risk indicators in Puerto Rican adolescents living in the mainland US (mostly in New York) and in Puerto Rico (mostly in San Juan). We are currently focused on the R61 (pilot) phase. This pilot phase aims to answer the question: Is there a relationship between indicators of SR and brain structure, brain function during reward-related decision making, and belief in a just world? If we are able to establish a relationship between SR indicators and outcomes, we will continue to the second phase of the study at that time. We will be collecting data from a total of 72 adolescents and their parents; n=36 in NY; n=36 in PR). Participation in the research study will include: 1. an interview with the parent or caregiver (approximately 2.5 hours) regarding the child's demographics, mental health symptoms, past experiences, the parent or caregiver's relationship with the child, as well as cultural values and acculturation; 2. an interview with the child (approximately 2.5 hours) regarding the child's past experiences, their current beliefs, personality traits and mental health symptoms; 3. an MRI scan for the child including task-based, structural and resting-state functional connectivity (approximately 1 hour).

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT06221839
The ClinicalTrials.gov registry entry for NCT06221839 describes a study currently listed as recruiting. It is categorized as an unspecified phase, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 72 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Columbia University, which has 875 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 2 conditions, with Structural Racism appearing as the primary indexed condition, and to 0 interventions. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT06221839 reports 2 study locations spanning 2 distinct geographic areas — top geographies include New York, Other. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above.
