简介：内感受意识（IA）被定义为准确感知内感受过程的能力，包括接收、处理和整合身体相关信号与外部刺激。内感受过程影响对刺激的动机性接近或回避行为。酒精和其他物质会对自主系统产生影响，导致内感受过程发生改变。患有 IA 障碍的人可能面临更高的成瘾风险，因为他们无法充分利用与身体相关的信号来指导他们的决策。本研究检验了酒精成瘾患者的 IA 会受到影响以及 IA 紊乱与酒精渴望相关的假设。 方法：本研究对 55 名根据《精神疾病诊断与统计手册》第四版文本修订版 (DSM-IV-TR) 标准诊断为酒精成瘾的患者和 52 名非成瘾健康对照者进行，这些患者已清醒至少两周。 IA 测量是使用心跳感知性能方法进行的，该方法通过将主观感知的心跳次数与在四个独立时间间隔内用心电图记录的客观心率测量值进行比较来确定参与者对自己心跳的意识。此外，对酒精成瘾患者组进行酒精使用障碍识别测试（AUDIT）、宾夕法尼亚酒精渴望量表（PACS）和强迫性饮酒量表（OCDS）。结果：酒精成瘾患者的IA评分显着低于对照组。根据 PACS 结果，酒精成瘾患者的 IA 评分与对酒精的渴望水平呈负相关。 结论：我们的结果证实了酒精成瘾患者的 IA 会受到影响的建议，并且较差的 IA 可能与酒精渴望相关，并且可能是饮酒行为的维持因素。
Introduction: Interoceptive awareness (IA) is defined as an ability to accurately perceive interoceptive processes, which comprise receiving, processing, and integrating body-relevant signals together with external stimuli. Interoceptive processes affect the motivated approach or avoidance behavior toward stimuli. Alcohol and other substances have effects on the autonomic system that result in altered interoceptive processes. Individuals who have disturbed IA may be at a higher risk of addiction because they are not able to utilize sufficiently body-relevant signals to guide their decision-making. The hypothesis that IA in alcohol-addicted patients would be affected and that the disturbed IA would be associated with alcohol craving was tested in this study.Methods: The study was conducted with 55 patients diagnosed with alcohol addiction according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR) criteria and who had been sober for at least two weeks and 52 non-addicted healthy controls. IA measurements were performed using the heartbeat perception performance method, which determines participants' awareness of their own heartbeat by comparing the number of subjectively perceived heartbeats with an objective heart rate measure recorded with ECG during four separate intervals. In addition, the Alcohol Use Disorders Identification Test (AUDIT), Penn Alcohol Craving Scale (PACS), and Obsessive Compulsive Drinking Scale (OCDS) were performed on the alcohol-addicted patient group.Results: IA scores were significantly lower in the alcohol-addicted patients than the control subjects. IA scores of alcohol-addicted patients were negatively correlated with the levels of alcohol craving sensations according to the PACS results.Conclusion: Our results corroborate the suggestion that IA in alcohol-addicted patients would be affected and that poor IA would be associated with alcohol craving and could be a maintaining factor for drinking behavior.
