Emotion dynamics and alcohol use in NIAAA-defined recovery from alcohol use disorder

项目摘要 酒精使用障碍（AUD）的恢复由两个因素组成：（1）停止饮酒 重度饮酒和（2）DSM-5 AUD诊断缓解（NIAAA，2021）。认识 AUD的慢性化和高复发率，恢复是一个随着时间的推移而展开的过程 并根据持续时间进行分类：初始（最多3个月），早期（3个月至一年）， 持续（1-5年）和稳定（5年或以上）。在这些不同的恢复期内， 负性情感（NA）是复发或恢复到未恢复状态的常见诱因 （Lowman等人，1996; Marlatt & Gordon，1985; Witkiewitz & Villarroel，2009）。但大多数 研究消极情绪和复发之间的关系， 负面影响情绪动力学，包括负面影响变异性和情绪 差异，已被证明提供额外的，独特的信息，而不是在平均捕获， 水平估计（Colgan等人，2019; Erbas等人，2021; Jenkins等人，2020年）。信息 可以提供一个更细致的理解， 影响恢复状态以及如何影响监管可能因恢复而异 持续时间最终，了解情绪动力学如何在NIAAA恢复中运作， 协助确定不同恢复期间干预和再干预的最佳时机 持续时间 为了更好地了解负性情绪变异性与酒精的关系 恢复，本研究建议在前3个恢复期的每一个中招募个体（例如， 最初的，早期的，持续的），他们已经停止了大量饮酒， DSM-5 AUD诊断，因此符合NIAAA AUD恢复标准。通过组合 基线评估和28天EMA报告，可以研究 情绪动力学对AUD恢复中酒精消费的影响，并探索可能 有助于解释这种关系。

Project Summary Recovery from Alcohol Use Disorder (AUD) is comprised of two factors: (1) cessation of heavy drinking and (2) remission from a DSM-5 AUD diagnosis (NIAAA, 2021). Recognizing both the chronicity of AUD and high relapse rates, recovery is a process that unfolds over time and is categorized based on duration: initial (up to 3 months), early (3 months to one year), sustained (1-5 years), and stable (5 or more years). Across these different recovery durations, negative affect (NA) is a common precipitant of relapse or return to a non-recovery status (Lowman et al., 1996; Marlatt & Gordon, 1985; Witkiewitz & Villarroel, 2009). However, most studies examining the relationship of negative affect and relapse report only mean levels of negative affect. Emotion dynamics, including negative affect variability and emotion differentiation, have been shown to provide additional, unique information not captured in mean- level estimates (Colgan et al., 2019; Erbas et al., 2021; Jenkins et al., 2020). Information provided by emotion dynamics can provide a more nuanced understanding of how negative affect impacts recovery status and how affect regulation may vary as a function of recovery duration. Ultimately, knowledge of how emotion dynamics operate in NIAAA recovery may assist with identifying optimal timing of intervention and re-intervention during different recovery durations In order to better to understand the relationship of negative affect variability and alcohol recovery, this study proposes to recruit individuals in each of the first 3 recovery durations (e.g., initial, early, and sustained) who have achieved cessation of heavy drinking and remission from a DSM-5 AUD diagnosis and thus meet NIAAA criteria for AUD recovery. By combining a baseline assessment with 28 days of EMA reporting, it is possible to study the relationship of emotion dynamics to alcohol consumption in AUD recovery and explore covariates that may help to explain this relationship.
