Background Interoception is the perception of afferent information that arises from any point within the body. Individual differences in interoception have been associated with affective processing and decision-making processing. The somatic marker hypothesis summarizes the potential effects of interoception on decision-making processes. According to this theory, individuals with interoceptive dysfunction exhibit disadvantageous decision making. Recently, enhancement of interoceptive accuracy, an element of interoception assessed by objective decision-making tasks, has been demonstrated using biofeedback. Garfinkle et al. developed an interoceptive training task, modified from the heartbeat perception task, which enhanced interoceptive accuracy and reduced anxiety symptoms. The purpose of this study was to determine the effects of interoceptive training on decision-making processes. Based on improvements in interoceptive accuracy, we hypothesized that decision-making scores would change in a manner indicative of increased rationality. Methods This longitudinal interventional study was performed with interoceptive training. Before and after the intervention, interoceptive accuracy and rationality of decision-making processes were assessed using a heartbeat perception task and rational decision-making tasks, respectively. Fourteen healthy volunteers (nine women; mean age, 21.9 ± 4.5 years) participated. The analysis included data from 12 participants. To detect individual differences in the effects of interoceptive accuracy on rationality of decision making, correlation analysis was conducted on change ratios of the indices of interoceptive accuracy and rationality of decision making. Results Interoceptive training resulted in significant enhancement of interoceptive accuracy scores and significant reductions in somatic symptom and state anxiety scores. In contrast, interoceptive training did not cause significant changes in decision-making indices. There was a significant positive correlation between change ratios of indices of interoceptive accuracy and rationality of decision making. Conclusions The results suggested a causal relation between interoception and rationality of decision making. These findings will enhance the understanding of mechanisms underlying alterations of decision-making related to psychotherapy by focusing on interoception.

内感受性训练对决策、焦虑和躯体症状的影响。

背景 内感受是对来自身体内任何一点的传入信息的感知。内感受的个体差异与情感处理和决策处理有关。体细胞标记假说总结了内感受对决策过程的潜在影响。根据这一理论,具有内感受功能障碍的个体表现出不利的决策。最近,已使用生物反馈证明了内感受准确性的增强,这是通过客观决策任务评估的内感受元素。加芬克尔等人。开发了一种内感受训练任务,从心跳感知任务修改而来,提高了内感受的准确性并减少了焦虑症状。本研究的目的是确定内感受训练对决策过程的影响。基于内感受准确性的改进,我们假设决策得分将以一种表明理性增加的方式发生变化。方法 这项纵向介入研究是通过内感受训练进行的。在干预前后,分别使用心跳感知任务和理性决策任务来评估决策过程的内感知准确性和合理性。十四名健康志愿者(九名女性;平均年龄,21.9 ± 4.5 岁)参加。该分析包括来自 12 名参与者的数据。检测内感受准确性对决策合理性影响的个体差异,对感知准确性和决策合理性指标的变化率进行相关性分析。结果 内感受训练导致内感受准确度得分显着提高,躯体症状和状态焦虑得分显着降低。相比之下,内感受训练并没有引起决策指数的显着变化。内感受准确度指标变化率与决策合理性呈显着正相关。结论 结果表明,内感受与决策的合理性之间存在因果关系。这些发现将通过关注内感受增强对与心理治疗相关的决策改变的潜在机制的理解。试用注册试用注册号:
