Testing the robustness of daily associations of affect with alcohol and cannabis use

Etiological models of alcohol and cannabis use disorders hypothesize that people are more likely to use and consume more of these substances when they experience heightened negative affect, yet recent EMA studies found no evidence for the daily association between negative affect and substance use. However, the theory underlying affect regulation of substance use is vague and has been translated into many different statistical tests across the literature, with inconsistent results. We aim to test the affect regulation hypothesis in a large sample of participants and across hundreds of statistical models to provide a robust understanding of whether and when affect regulation is supported in everyday life. This will enable us to update theoretical models and inform future clinical interventions aimed at the affect-substance use association.

病因模型对于酒精和毒品使用障碍的假设认为，人们在经历增强的负面情感时更有可能使用和消费这些物质。然而，最近的每日情绪评估（EMA）研究表明，负面情感与物质使用之间的每日关联并无证据。尽管如此，关于物质使用情感调节的理论基础模糊不清，且在文献中被转化为多种不同的统计检验，结果并不一致。我们的目标是在大量参与者的样本中，以及数百个统计模型中测试情感调节假设，以提供对情感调节在日常生活中的支持与否及何时支持的稳健理解。这将使我们能够更新理论模型，并为旨在影响情感-物质使用关联的未来临床干预提供信息。
