Relationships between presence of irritable bowel syndrome (IBS) and generalized anxiety disorder (GAD), chronic worry, neuroticism, anxiety sensitivity and anxiety about visceral sensations were examined among university students.
College student participants were administered self-report diagnostic measures of IBS and GAD, the Penn State Worry Questionnaire (PSWQ), the Neuroticism subscale of the Eysenck Personality Questionnaire, the Anxiety Sensitivity Index (ASI) and five additional items designed to measure visceral anxiety.
The prevalence of IBS and its associated characteristics among students were similar to previous community survey studies, with the exception of lower symptom severity in the university sample. IBS was associated with a higher frequency of GAD and greater worry, neuroticism, anxiety sensitivity and visceral anxiety. Logistic regression analyses further showed that the measure of anxiety specific to visceral sensations was the strongest predictor of IBS diagnostic status.
While various aspects of anxiety appear related to IBS, specific anxiety about visceral sensations appears to be the most significant factor. Implications of the associations between anxiety-related variables, particularly anxiety about visceral sensations, are discussed.
在大学生中研究肠易激综合征（IBS）与广泛性焦虑症（GAD）、慢性担忧、神经质、焦虑敏感性以及对内脏感觉的焦虑之间的关系。
对大学生参与者进行IBS和GAD的自我报告诊断测量、宾夕法尼亚州立大学担忧问卷（PSWQ）、艾森克人格问卷的神经质分量表、焦虑敏感性指数（ASI）以及另外五个用于测量内脏焦虑的项目。
学生中IBS及其相关特征的患病率与先前的社区调查研究相似，但大学样本中的症状严重程度较低。IBS与较高频率的GAD以及更大程度的担忧、神经质、焦虑敏感性和内脏焦虑相关。逻辑回归分析进一步表明，特定于内脏感觉的焦虑测量是IBS诊断状态的最强预测指标。
虽然焦虑的各个方面似乎都与IBS有关，但对内脏感觉的特定焦虑似乎是最重要的因素。讨论了与焦虑相关变量之间关联的意义，特别是对内脏感觉的焦虑。
