据报道，自闭症谱系中的个体表现出内感受的改变，内感受是身体内部状态的感觉。内感受感觉问卷（ISQ）是一个20项自我报告的内感受测量，专门用于测量自闭症患者的这种结构。然而，ISQ的心理测量学以前没有在自闭症个体的大样本中进行过评估。使用验证性因素分析，我们评估了潜在的结构的ISQ在一个大的在线样本的成年人的自闭症谱系障碍，发现一维模型拟合数据较差。本研究采用误设定分析法确定局部错配区域，运用项目反应理论考察七点反应量表的适用性，去除冗余项目，并将反应选项折叠，提出一种新的八项、五个反应的选择ISQ。修订后的五个响应选择ISQ（ISQ-8）显示出更好的拟合度，同时保持了较高的内部可靠性。差异项目功能（DIF）分析表明，ISQ-8的项目在自闭症青少年和成年人以及其他多个社会人口群体中的回答方式相当。我们的研究结果受到限制的事实是，我们没有收集数据，典型的发展控制，防止诊断状态的DIF分析。此外，虽然这项研究提出了一个新的5响应量表的ISQ-8，我们的数据没有收集使用这种方法，因此，心理测量特性的修订版的仪器需要进一步调查。ISQ-8显示出作为自闭症谱系青少年和成人内感受的可靠和有效的测量方法的希望，但需要更多的工作来检查其在这一人群中的心理测量学。已经创建了一个免费的在线分数计算器，以方便使用ISQ-8潜在特质分数对自闭症青少年和成人进行进一步研究（可在https：//asdmeasures.shinyapps.io/ISQ_score/获得）。在线版本包含补充材料，可通过10.1186/s13229-021-00440-y获得。
Individuals on the autism spectrum are reported to display alterations in interoception, the sense of the internal state of the body. The Interoception Sensory Questionnaire (ISQ) is a 20-item self-report measure of interoception specifically intended to measure this construct in autistic people. The psychometrics of the ISQ, however, have not previously been evaluated in a large sample of autistic individuals. Using confirmatory factor analysis, we evaluated the latent structure of the ISQ in a large online sample of adults on the autism spectrum and found that the unidimensional model fit the data poorly. Using misspecification analysis to identify areas of local misfit and item response theory to investigate the appropriateness of the seven-point response scale, we removed redundant items and collapsed the response options to put forth a novel eight-item, five-response choice ISQ. The revised, five-response choice ISQ (ISQ-8) showed much improved fit while maintaining high internal reliability. Differential item functioning (DIF) analyses indicated that the items of the ISQ-8 were answered in comparable ways by autistic adolescents and adults and across multiple other sociodemographic groups. Our results were limited by the fact that we did not collect data for typically developing controls, preventing the analysis of DIF by diagnostic status. Additionally, while this study proposes a new 5-response scale for the ISQ-8, our data were not collected using this method; thus, the psychometric properties for the revised version of this instrument require further investigation. The ISQ-8 shows promise as a reliable and valid measure of interoception in adolescents and adults on the autism spectrum, but additional work is needed to examine its psychometrics in this population. A free online score calculator has been created to facilitate the use of ISQ-8 latent trait scores for further studies of autistic adolescents and adults (available at https://asdmeasures.shinyapps.io/ISQ_score/).
