Interoception is the sense of the body's physiological state. Both the ability to accurately perceive bodily signals, and the self-reported sensibility for the body were assumed to be reciprocally associated with negative affect. Up to now, the specific interplay between dimensions of interoception and negative affect remains largely unknown. We investigated the interplay of cardioceptive accuracy assessed by a heartbeat tracking task, facets of interoceptive sensibility as measured by the Multidimensional Assessment of Interoceptive Awareness, and trait anxiety as measured by the trait version of the State-Trait-Anxiety inventory across two studies (n = 243) using a network analytic approach. The resulting network structure suggested a relationship between interoceptive sensibility and trait anxiety through the tendency to evaluate one's own body as trustworthy. Interoceptive accuracy showed no considerable associations to other variables. The findings question the relevance of cardiac interoceptive accuracy for trait anxiety in healthy populations.

内感受是对身体生理状态的感觉。准确感知身体信号的能力和自我报告的身体敏感性都被认为与负面情绪相互关联。到目前为止，内感受和负面影响维度之间的具体相互作用在很大程度上仍然未知。我们调查了通过心跳跟踪任务评估的心脏感受准确性、通过内感受意识多维评估测量的内感受敏感性方面以及通过两项研究中的状态-特质-焦虑清单的特质版本测量的特质焦虑之间的相互作用（n = 243) 使用网络分析方法。由此产生的网络结构通过将自己的身体评估为值得信赖的倾向，表明了内感受性和特质焦虑之间的关系。内感受准确度与其他变量没有显着关联。研究结果质疑心脏内感受准确性与健康人群特质焦虑的相关性。
