The self-reported perception of bodily sensations is assumed predictive for health and disease. Existing questionnaires mostly focus on aversive sensations, and associated emotions and cognitions, which potentially confounds associations between interoception and illness. Therefore, we developed the Three-domain Interoceptive Sensations Questionnaire (THISQ), assessing self-reported perception of neutral respiratory, cardiac, and gastroesophageal sensations.
Using cross-sectional surveys, we developed and validated the THISQ.
In Sample 1 (n = 357), a pool of 28 Dutch items was subjected to exploratory factor analysis. Eighteen items with a primary factor loading >.40 were retained for confirmatory factor analysis in Sample 2 (n = 374) and Sample 3 (n = 484) for the validation of the Dutch and English questionnaire, respectively.
Analyses supported the 3-factor solution: cardiorespiratory activation, cardiorespiratory deactivation, and gastroesophageal sensations. Scales showed acceptable to good internal consistency. Convergent validity was confirmed by significant medium associations between THISQ scores and other self-report measures of interoception. Divergent validity was supported by non-significant or small associations with measures of negative affectivity and symptom-related anxiety.
Our findings suggest that the Dutch and English THISQs are valid and reliable self-report measures of interoception, which could advance our understanding of interoceptive processes in health and disease.

自我报告的身体感觉认知被认为对健康和疾病具有预测性。现有的问卷大多关注厌恶感觉以及相关的情绪和认知，这可能会混淆内感受与疾病之间的关联。因此，我们开发了三领域内感受觉问卷（THISQ），用于评估自我报告的对中性呼吸、心脏和胃食管感觉的认知。
我们通过横断面调查开发并验证了THISQ。
在样本1（n = 357）中，对一组28个荷兰语项目进行探索性因子分析。保留了18个主因子载荷>.40的项目，分别在样本2（n = 374）和样本3（n = 484）中进行验证性因子分析，以验证荷兰语和英语问卷。
分析支持三因子解决方案：心肺激活、心肺失活和胃食管感觉。量表显示出可接受至良好的内部一致性。通过THISQ得分与其他内感受自我报告测量之间显著的中等关联，证实了聚合效度。与消极情感和症状相关焦虑测量的非显著或小关联支持了区分效度。
我们的研究结果表明，荷兰语和英语的THISQs是有效的、可靠的内感受自我报告测量工具，这可能会增进我们对健康和疾病中内感受过程的理解。
