Alcohol and cannabis use predicted by affect-urgency interactions in everyday life

Urgency is a personality trait quantifying individual differences in impulsive behaviors driven by intense emotions and is hypothesized to moderate associations between affect and alcohol use. However, this hypothesis has received inconsistent support in studies that repeatedly sample individuals in their natural environment. Although cannabis use is theorized to serve the same emotion regulation function as alcohol use, no research has tested the hypothesis that urgency moderates the associations between affect and cannabis use in daily diary and ecological momentary assessment (EMA) research. Clarifying the role that urgency potentially plays in the development of problematic substance use in everyday life is critical to the development of targeted prevention and treatment interventions. In this Registered Report, we will test an exhaustive list of affect dimensions × trait- and state-level urgency interactions predicting alcohol and cannabis use in a large sample (n = 500) of young adults who use both substances regularly. In this way, we aim to provide a conclusive answer to the question whether urgency moderates daily associations of negative and positive affect with alcohol and cannabis use in EMA data. Five-hundred young adults (stratified by age and sex) completed five short EMA surveys per day for 32 days across eight weekends (Thursday-Sunday).

紧迫性作为一种个性特征，衡量了由强烈情感驱动的冲动行为个体差异，并被假定为调节情感与酒精使用之间的关联。然而，这一假设在重复对自然环境中的人进行抽样研究的文献中得到了不一致的支持。尽管大麻使用被理论化为与酒精使用具有相同的情绪调节功能，但尚无研究测试紧迫性调节情感与日常日记和生态瞬时评估（EMA）研究中大麻使用的假设。阐明紧迫性在日常生活中可能导致问题性物质使用的潜在作用，对于开发针对性的预防和治疗干预措施至关重要。在本注册报告中，我们将测试一个详尽的情感维度与特质和状态层面紧迫性相互作用列表，以预测大量（n = 500）同时定期使用酒精和大麻的年轻人的酒精和大麻使用情况。通过这种方式，我们旨在对紧迫性是否调节EMA数据中负面和正面情感与酒精和大麻使用之间的日常关联这一问题的答案给出一个明确的结论。500名年轻人（按年龄和性别分层）在八个周末（周四至周日）的32天内，每天完成五次简短的EMA调查。
