OBJECTIVE Individuals are often inaccurate at estimating levels of intoxication following doses of alcohol. Previous research has shown that when required to estimate (BAC) at different time points, participants often underestimate their BACs and amounts of alcohol consumed. The present study aimed to increase drinkers' BAC estimation accuracy after drinking alcohol using mindfulness-based feedback to increase their awareness of the interoceptive cues associated with alcohol intoxication. METHOD Thirty-three adults were given 0.65 g/kg of alcohol and received one of three training conditions: BAC feedback only, body scan exercise + BAC feedback and no treatment control. Those in the BAC feedback group received feedback concerning their observed BAC during dose exposure. Participants in the body scan group received BAC feedback and underwent a mindfulness exercise to enhance their perception of the acute subjective effects of alcohol. The control group received no BAC estimation training. Participants attended four study sessions: Two training sessions where participants underwent structured training based on their condition and two retention sessions to test for the lasting effects of the training exercises. RESULTS Retention tests showed that participants in both treatment groups were most accurate in estimating their BACs. There were no differences among the groups in their perceived levels of intoxication at posttraining. The findings suggest that BAC feedback, alone and in combination with, mindfulness training can improve accuracy in estimating BACs. CONCLUSIONS The findings provide preliminary support for the efficacy of mindfulness training in combination with BAC feedback to improve BAC estimation accuracy.

使用正念训练来改善饮酒期间的 BAC 自我评估。

目的 个人对饮酒后中毒程度的估计常常不准确。先前的研究表明，当需要估计不同时间点的 BAC 时，参与者常常会低估他们的 BAC 和饮酒量。本研究旨在使用基于正念的反馈来提高饮酒者饮酒后 BAC 估计的准确性，以提高他们对与酒精中毒相关的内感受线索的认识。方法 33 名成年人被给予 0.65 g/kg 的酒精，并接受三种训练条件之一：仅 BAC 反馈、身体扫描运动 + BAC 反馈和无治疗控制。BAC 反馈组的参与者收到了有关他们在剂量暴露期间观察到的 BAC 的反馈。身体扫描组的参与者收到了 BAC 反馈，并进行了正念练习，以增强他们对酒精急性主观影响的感知。对照组未接受 BAC 估计培训。参与者参加了四次学习课程：两次培训课程，参与者根据自己的情况进行结构化培训；两次保留课程，以测试培训练习的持久效果。结果 记忆力测试表明，两个治疗组的参与者在估计 BAC 方面最为准确。各组在训练后感知的中毒程度没有差异。研究结果表明，BAC 反馈单独或与正念训练相结合，可以提高估计 BAC 的准确性。结论 研究结果为正念训练与 BAC 反馈相结合提高 BAC 估计准确性的有效性提供了初步支持。（PsycInfo 数据库记录 (c) 2023 APA，保留所有权利）。
