Interoception is a multi-facetted phenomenon including interoceptive accuracy, awareness and sensibility. Deficits in interoception have been associated with psychological distress. However, little is known about the course of interoception over time. The present study aimed at examining interoception in an ecological momentary assessment (EMA)-setting. A seven-day smartphone-based EMA was conducted in a community sample of sixty-one participants (age: = 24.1, = 7.00, = 54 female (88.5%)). To control for potential practice effects of repeated assessments during the EMA phase, participants were randomly assigned to a control ( = 30) and an interoception ( = 31) group. The latter was assessed for interoceptive accuracy, awareness and sensibility. Before and after the EMA phase, all participants were assessed for interoception in the laboratory. Multilevel analyses revealed significant fluctuations for all three interoceptive facets, around 50% of variance was due to within-person variability. There were only practice effects for the subscale "Attention Regulation", measuring interoceptive sensibility. The facets of interoception can be assessed in an EMA-setting. Repeated interoceptive assessments do not necessarily lead to an improvement of participants' interoceptive abilities. It could be shown that all interoceptive facets fluctuate, which should be considered in future research.
内感受是一种多方面的现象，包括内感受准确性、意识和敏感性。内感受缺陷与心理困扰有关。然而，关于内感受随时间的变化过程知之甚少。本研究旨在通过生态瞬时评估 (EMA) 来检查内感受。在社区样本的 61 名参与者（年龄：= 24.1，= 7.00，= 54 名女性（88.5%））中进行了为期七天的基于智能手机的 EMA。为了控制 EMA 阶段重复评估的潜在练习效应，参与者被随机分配到对照组（= 30）和内感受组（= 31）。后者被评估内感受准确性、意识和敏感性。在 EMA 阶段之前和之后，所有参与者都在实验室中评估内感受。多层次分析显示，所有三个内感受方面都有显著波动，约 50%的方差归因于个体内变异性。只有“注意调节”子量表的评估存在练习效应，该子量表衡量内感受敏感性。内感受的各个方面可以在 EMA 环境中进行评估。重复的内感受评估不一定会提高参与者的内感受能力。研究表明，所有的内感受方面都存在波动，这在未来的研究中应该得到考虑。
