Research on substance use among racial-ethnic minority populations notes that discrimination experiences predict substance use outcomes. Individual-level factors, such as impulsivity, are also known risk factors for substance use. However, little is known about the direct and interaction effects between discrimination experiences and impulsivity among racial-ethnic minority youth. The current study examines the effects of perceived experiences of discrimination on alcohol and marijuana use among racial-ethnic minority youth, and whether individual differences in impulsivity traits help to further understand potential risk for substance use.
Participants were 112 racial-ethnic minority adolescents (Mage = 15.27; African American, Hispanic, Multiracial, Native American/Alaskan Native, or Other). Adolescents completed self-report measures of perceived experiences of discrimination, alcohol and marijuana use (past year occurrence and problematic use), and five impulsivity traits (i.e., sensation seeking, lack of planning, lack of perseverance, negative urgency, and positive urgency).
A significant main effect of perceived discrimination on problem marijuana use was found, as well as a significant main effect of lack of premeditation on current marijuana use. Several marginally significant main effects emerged for alcohol use and problem alcohol use (i.e., positive urgency and sensation seeking, respectively).
While no significant moderation effects emerged, marginal findings suggest a potential interactive effect of discrimination and impulsivity traits on problem alcohol and marijuana use among racial-ethnic minority youth. Further research is needed in this area to replicate findings, which is critical to informing effective intervention and prevention efforts for this population of youth.
对少数族裔人群物质使用的研究表明，歧视经历可预测物质使用结果。冲动等个体因素也是物质使用的已知风险因素。然而，对于少数族裔青年中歧视经历和冲动之间的直接和交互作用知之甚少。本研究考察了感知到的歧视经历对少数族裔青年的酒精和大麻使用的影响，以及冲动特质的个体差异是否有助于进一步了解物质使用的潜在风险。
参与者为 112 名少数族裔青少年（Mage=15.27；非裔美国人、西班牙裔、多种族、美国原住民/阿拉斯加原住民或其他）。青少年完成了感知歧视经历、酒精和大麻使用（过去一年的发生和问题使用）以及五种冲动特质（即感觉寻求、缺乏计划、缺乏毅力、消极冲动和积极冲动）的自我报告测量。
感知歧视对大麻问题使用有显著的主效应，缺乏预见到的计划对当前大麻使用有显著的主效应。酒精使用和问题酒精使用也出现了几个边缘显著的主效应（即积极冲动和感觉寻求）。
虽然没有出现显著的调节效应，但边缘结果表明，歧视和冲动特质对少数族裔青年的酒精和大麻问题使用可能存在潜在的交互作用。需要在这一领域进行进一步的研究，以复制这些发现，这对于为这一年轻人群提供有效的干预和预防措施至关重要。
