Knowing when perceiving inner bodily signals better and when perceiving them worse is a health relevant but understudied dimension of interoception. Therefore, the present study assessed interoceptive metacognition (IMC) as the skill to adequately monitor interoceptive accuracy in the cardiac domain. We used the Graz Ambulatory Interoception task (GRAIT), which applied two intervals of the heartbeat tracking task 12 times a day for 3 days in total to n = 66 participants. We assessed IMC as the relative correspondence between interoceptive accuracy and the subjective confidence ratings. We found that 6 % of the total IMC variance was due to person, which was assessed reliable ($R_{\mathit{KRn}}$=0.81). Furthermore, the between-person variation of IMC was negatively associated with the MAIA (especially attention regulation and self-regulation). People who believe that they are aware of their interoceptive experiences (MAIA) showed lower IMC. This study advocates the assessment of interoception in everyday life.

了解何时感知内部身体信号更好、何时感知更差是内感受的一个与健康相关但尚未得到充分研究的维度。因此，本研究将内感受元认知（IMC）评估为充分监测心脏领域内感受准确性的技能。我们使用了格拉茨动态内感受任务 (GRAIT)，该任务对 n = 66 名参与者应用两次心跳跟踪任务，每天 12 次，总共 3 天。我们将 IMC 评估为内感受准确性和主观置信度之间的相对对应关系。我们发现 IMC 总方差的 6% 是由人造成的，这一点被评估为可靠（${右}_{\mathit{钾盐}}$=0.81）。此外，IMC 的人际差异与 MAIA（尤其是注意力调节和自我调节）呈负相关。相信自己了解自己的内感受体验 (MAIA) 的人表现出较低的 IMC。这项研究提倡在日常生活中评估内感受。
