背景：与胃肠道感觉、症状或可能发生这些症状的环境相关的焦虑被认为在肠易激综合征患者的病理生理学和健康结局中起着重要作用。目的：研制一种有效可靠的胃肠道症状特异性焦虑心理测量仪。方法：外部和内部专家小组以及患者焦点小组评估了从心理学和胃肠道文献中收集的大量潜在项目。然后对96名诊断为肠易激综合征的患者进行潜在量表项目和一套验证问卷。最后的项目选择是基于严格的经验标准和最终量表的心理测量特性进行了检查。结果：最终编制的15项单项内脏敏感性指数量表具有良好的信度，内容效度、收敛效度、发散效度和预测效度均较好。结论：研究结果表明，内脏敏感性指数是一种可靠、有效的胃肠道症状特异性焦虑测量方法，可用于肠易激综合征患者症状相关焦虑的临床评估、治疗结果研究和机制研究。
Background: Anxiety related to gastrointestinal sensations, symptoms or the contexts in which these may occur is thought to play a significant role in the pathophysiology as well as in the health outcomes of patients with irritable bowel syndrome.Aim: To develop a valid and reliable psychometric instrument that measures gastrointestinal symptom-specific anxiety.Methods: External and internal expert panels as well as a patient focus group evaluated a large pool of potential item stems gathered from the psychological and gastrointestinal literature. Potential scale items were then administered to 96 patients diagnosed with irritable bowel syndrome along with a set of validating questionnaires. Final item selection was based upon rigorous empirical criteria and the psychometric properties of the final scale were examined.Results: A final unidimensional 15-item scale, the Visceral Sensitivity Index, demonstrated excellent reliability as well as good content, convergent, divergent and predictive validity.Conclusions: The findings suggest that the Visceral Sensitivity Index is a reliable, valid measure of gastrointestinal symptom-specific anxiety that may be useful for clinical assessment, treatment outcome studies, and mechanistic studies of the role of symptom-related anxiety in patients with irritable bowel syndrome.
