INTRODUCTION People low in trait distress tolerance are at higher risk for harmful patterns of substance use. Some evidence suggests that maladaptive motives for substance use account for this correlation. However, the generality of these associations remains in doubt because virtually all available data come from North American samples. METHOD Using data from 7 countries (total N = 5858; U.S., Argentina, Uruguay, Spain, South Africa, Canada, and England), we examined distress tolerance's association with alcohol- and cannabis-related problems in young adults. On an exploratory basis, we examined how distress tolerance related to different substance-use motivations. RESULTS We found that distress tolerance was inversely related to problematic alcohol and cannabis use (rs = -0.14 and - 0.13). There was notable variation across countries in the magnitude of these effects, particularly for cannabis-related problems. Additionally, exploratory analyses revealed statistically significant (cross-sectional) indirect effects of distress tolerance on substance-related problems via substance-use motivations related to neutralizing negative emotions. CONCLUSIONS Distress tolerance's role in substance-use problems appears to generalize beyond North America, although effect sizes were generally small and varied notably across geographical regions. Distress tolerance's connection with negative reinforcement processes (e.g., coping motives) warrants attention as a possible mediator of its association with problematic substance use.

四大洲年轻人的痛苦耐受力与药物使用动机和问题有关。


引言 特质痛苦耐受力较低的人采用有害物质使用模式的风险较高。一些证据表明，物质使用的适应不良动机可以解释这种相关性。然而，这些关联的普遍性仍然值得怀疑，因为几乎所有可用数据都来自北美样本。方法 使用来自 7 个国家（总计 N = 5858；美国、阿根廷、乌拉圭、西班牙、南非、加拿大和英国）的数据，我们研究了年轻人的痛苦耐受性与酒精和大麻相关问题的关联。在探索性的基础上，我们研究了痛苦耐受性与不同物质使用动机之间的关系。结果我们发现，应激耐受力与有问题的酒精和大麻使用呈负相关（rs = -0.14 和 - 0.13）。这些影响的严重程度在各国之间存在显着差异，特别是与大麻相关的问题。此外，探索性分析揭示了痛苦耐受力通过与中和负面情绪相关的物质使用动机对物质相关问题产生统计上显着的（横截面）间接影响。结论 痛苦耐受力在药物滥用问题中的作用似乎普遍存在于北美以外的地区，尽管其效应规模一般较小，并且在不同地理区域之间差异显着。痛苦耐受力与负强化过程（例如，应对动机）的联系值得关注，因为它可能是其与有问题的物质使用相关的中介因素。
