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

项目摘要 酒精使用障碍(AUD)的康复由两个因素组成：(1)停止 酗酒和(2)从DSM-5和UD诊断中缓解(NIAAA，2021)。认识 AUD的长期性和高复发率，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年或更长时间)。在这些不同的恢复持续时间内， 负面影响(NA)是复发或返回到不可恢复状态的常见诱因 (Lowman等人，1996；Marlatt&Gordon，1985；Witkiewitz&Villarroel，2009)。然而，大多数 检查负面情绪和复发关系的研究仅报告平均水平 负面影响。情绪动力学，包括负面情绪变异性和情绪 差异，已被证明提供了额外的，独特的信息，而不是平均- 水平估计(Colgan等人，2019年；Erbas等人，2021年；Jenkins等人，2020年)。信息 由情绪动力学提供，可以提供对负面程度的更细微的理解 影响影响恢复状态以及如何影响监管可作为恢复的函数而变化 持续时间。最终，关于情绪动力学如何在NIAAA康复中运作的知识可能 协助确定不同恢复期间干预和重新干预的最佳时机 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，这项研究建议在前3个恢复持续时间的每个阶段招募个人(例如， 初步、早期和持续)，已实现戒酒并缓解 DSM-5 AUD诊断，因此符合NIAAA的AUD恢复标准。通过将一个 基线评估与28天的EMA报告，有可能研究 情绪动力学对AUD康复过程中饮酒的影响，并探索可能 帮助解释这种关系。

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.
