Abstract
Although national-level racial disparities in nonmedical prescription opioid (NMPO) use are well-established, local-level comparisons between Black and White college students remain scarce. This study investigates racial disparities in intentions to use NMPO and explores theory-based individual and socio-contextual factors associated with these intentions. A cross-sectional survey was conducted among full-time students at the University of Missouri-Columbia. Demographics, theory-based factors, and NMPO use intentions were assessed from 498 students (86 percent White, 14 percent Black). Statistical analyses included chi-square tests, Welch's t-tests, and hierarchical multiple linear regressions using the R program. Black students demonstrated significantly higher NMPO intentions compared to Whites (p [less than] 0.05), with greater perceived susceptibility to opioid use. Hierarchical regression revealed individual factors (attitudes towards NMPO use, depressive symptoms, opioid and substance use history) as stronger predictors of NMPO intentions than socio-contextual factors. Race moderated the effect of attitudes on NMPO intentions, with a stronger association observed among Blacks. Addressing racial disparities in NMPO intentions among college students is crucial. Culturally tailored interventions targeting individual and socio-contextual factors, especially attitudes towards NMPO use, are essential for reducing intentions to use NMPO, particularly among Black students.
