Impulsivity is both a risk factor for and a consequence of alcohol use disorder (AUD), for which mindfulness-based approaches have been proven to be effective. However, the specific relationship between mindfulness and impulsivity has been little explored in the literature, especially in people with AUD. This study aims to investigate the relationship between different facets of dispositional mindfulness and impulsivity among people with AUD in an inpatient setting in Brazil. Participants (= 165) completed the following self-report measures: the Alcohol Use Disorders Identification Test (AUDIT), the Five Facets of Mindfulness Questionnaire (FFMQ-SF), and the Short UPPS-P Impulsive Behavior Scale (SUPPS-P). Multiple imputation techniques and linear models were employed to assess the relationships between dispositional mindfulness and impulsivity. In complete case analysis, the UPPS-P facet "lack of premeditation" was inversely related to the FFMQ facet "non-reactivity" ( = -0.17; = 0.01); and "positive urgency" was inversely related to "act with awareness" ( = -0.27, = 0.02) and "non-reactivity" ( = -0.17, = 0.01). Relationships of varying magnitudes between dispositional mindfulness and impulsivity domains among people with AUD were found, suggesting that higher mindfulness skills are related to less impulsive traits. Our results encourage further longitudinal studies evaluating the potential of specific mindfulness components to decrease impulsivity among AUD inpatients, including its underlying mechanisms.
冲动既是酒精使用障碍（AUD）的一个风险因素，也是其后果，而基于正念的方法已被证明对此有效。然而，文献中对正念与冲动之间的具体关系探讨甚少，尤其是在 AUD 患者中。本研究旨在调查巴西住院 AUD 患者中，不同特质正念维度与冲动之间的关系。参与者（n=165）完成了以下自评量表：酒精使用障碍识别测试（AUDIT）、五因素正念量表（FFMQ-SF）和 UPPS-P 冲动行为量表短式版（SUPPS-P）。采用多重插补技术和线性模型评估特质正念与冲动之间的关系。在完全案例分析中，UPPS-P 维度“缺乏深思熟虑”与 FFMQ 维度“非反应性”呈负相关（r=-0.17，p=0.01）；“积极紧迫感”与“觉察行动”（r=-0.27，p=0.02）和“非反应性”（r=-0.17，p=0.01）呈负相关。在 AUD 患者中，特质正念与冲动各个维度之间存在着不同程度的关系，这表明更高的正念技能与较少的冲动特质有关。我们的研究结果鼓励进一步进行纵向研究，评估特定正念成分在降低 AUD 住院患者冲动方面的潜力，包括其潜在机制。
