Abstract：
The Visceral Sensitivity Index (VSI) represents a significant advancement in the assessment of gastrointestinal-specific anxiety among patients with irritable bowel syndrome (IBS) and chronic inflammatory bowel diseases (IBD)-such as ulcerative colitis and Crohn\'s disease. However, an Italian version of the instrument is not yet available for the Italian-speaking population. This study utilized a national sample of 500 individuals divided into four groups: (a) patients with Crohn\'s disease, (b) patients with ulcerative colitis, (c) patients with IBS, and (d) healthy controls (individuals without any diagnoses) to test the validity and reliability of the Italian VSI. Using back-translation methodology to ensure translation fidelity, this research applied a questionnaire and the VSI through an online format to 500 participants. Confirmatory Factor Analysis (CFA) revealed that the Italian VSI had excellent psychometric properties, demonstrating high internal consistency (Cronbach\'s α = 0.949) and construct validity. The scale proved sensitive in detecting significant differences in visceral sensitivity among groups, highlighting its utility as a clinical and research assessment tool. Specifically, the Italian VSI exhibited a unidimensional factorial structure and maintained a strong correlation with interoceptive awareness, type of disease, and gastrointestinal symptom severity, confirming its role in enhancing the understanding and management of IBD and IBS in Italy.
摘要：
内脏敏感性指数（VSI）代表了肠易激综合征（IBS）和慢性炎症性肠病（IBD）患者（如溃疡性结肠炎和克罗恩病）的胃肠道特异性焦虑评估的显着进步。然而,该乐器的意大利语版本尚未适用于讲意大利语的人群。这项研究利用了全国500人的样本，分为四组：（a）克罗恩病患者，(b)溃疡性结肠炎患者，(c)IBS患者，和（d）健康对照（没有任何诊断的个体），以测试意大利VSI的有效性和可靠性。使用回译方法来确保翻译的保真度，这项研究通过在线形式对500名参与者进行了问卷调查和VSI.验证性因子分析(CFA)显示，意大利VSI具有出色的心理测量特性，表现出较高的内部一致性(Cronbach'sα=0.949)和结构效度。该量表在检测各组内脏敏感性的显着差异方面被证明是敏感的，强调其作为临床和研究评估工具的实用性。具体来说,意大利VSI表现出一维阶乘结构，并与相互感受意识保持很强的相关性，疾病类型,和胃肠道症状的严重程度，确认其在加强意大利IBD和IBS的理解和管理方面的作用。
