Methodological Challenges and Insights in Research on Racial Discrimination and Substance Use Among Black College Students: A Scoping Review.
Article in Journal of racial and ethnic health disparities, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundDespite growing evidence that racial discrimination is associated with substance use among Black Americans, the existing research on Black college students has not been synthesized. In response, this scoping review investigated the state of research on racial discrimination and substance use among Black college students in the United States (U.S.).
methodsUsing PRISMA-ScR reporting guidelines, we searched 23 databases and screened 254 non-duplicative titles and abstracts published from earliest records to December 2022. We extracted key study characteristics and described results through a narrative synthesis of the evidence.
resultsEighteen studies met inclusion criteria. Studies primarily comprised Black undergraduates (Female > 50%, MAge = 20.9 years) from single institutions. Most studies found a significant positive association between racial discrimination and alcohol, with stronger evidence for consequences than consumption. Findings for cannabis, tobacco use, and binge drinking were less consistent. Eleven studies employed complex modeling (i.e., mediation and moderation analyses), but most (17) were cross-sectional and assessed retrospective self-reports. Both single-item and multi-item measures were used to assess racial discrimination, predominantly capturing overt individual-level experiences. Several discriminatory experiences received scant attention, and most studies lacked an explicit theoretical justification for analyses.
conclusionThis review highlights that racial discrimination impacts substance use risk among Black college students through various pathways. With rising sociopolitical tensions in the U.S. and on college campuses, there is an urgent need for targeted prevention efforts at both institutional and individual levels. We identified critical gaps in evidence and provided recommendations to enhance methodological rigor in future research.
