食道过度警惕和焦虑正在成为吞咽困难症状和食道诊断中生活质量下降的重要驱动因素。食道过度警觉和焦虑量表(EHAS)是这些认知-情感过程的有效测量。然而，它的长度可能会阻碍它在临床实践中的使用。我们的目标是使用既定的心理测量学方法创建一个简短的EHAS版本。对前往大学食道动力诊所进行诊断性测试的患者进行了回顾。如果患者在活动测试时完成了15个项目的EHAS和评估吞咽困难严重程度和健康相关生活质量(HRQOL)的问卷，就包括在内。主成分因子分析确定了可能剔除的项目。对完整版和简式版(EHAS-SF)进行信度和同时效度检验。3976例确诊为食道疾病的成人患者中，30%患有失弛缓症或EGJOO，13%患有EoE，13%患有GERD，39%运动正常。根据因子负荷值0.70，从量表中删除了8个条目，得到了一个包含7个条目的EHAS-SF得分从0到28。EHAS-SF表现出极好的内部一致性(α=0.91)和分半信度(0.88)，正如在当前研究和先前验证的完整EHAS中发现的那样。EHAS-SF与吞咽困难(r=0.33)和生活质量(r=−0.73，P均.001)之间存在一致的效度。EHAS-SF是一个由7个条目组成的量表，用于评估食道过度警惕和症状特定焦虑，其表现与最初的15个条目版本一样。较短的问卷可以在临床实践中实施。对于临床医生来说，EHAS-SF是一个有用的工具，可以快速评估过度警惕和焦虑是如何导致患者的临床表现的。
Esophageal hypervigilance and anxiety are emerging as important drivers of dysphagia symptoms and reduced quality of life across esophageal diagnoses. The esophageal hypervigilance and anxiety scale (EHAS) is a validated measure of these cognitive-affective processes. However, its length may preclude it from use in clinical practice. We aimed to create a short form version of the EHAS using established psychometric practices. A retrospective review of a registry of patients who visited a university-based esophageal motility clinic for diagnostic testing was conducted. Patients were included if they completed the 15-item EHAS and questionnaires assessing dysphagia severity and health-related quality of life (HRQOL) at the time of motility testing. Principle components factor analysis identified items for possible removal. Tests for reliability and concurrent validity were performed on the full EHAS and short-form version (EHAS-SF). 3,976 adult patients with confirmed esophageal disease were included: 30% with achalasia or EGJOO, 13% with EoE, 13% with GERD, 39% normal motility. Eight items were removed from the scale based on a factor loading of > 0.70, resulting in a single scale 7-item EHAS-SF scored from 0 to 28. The EHAS-SF demonstrated excellent internal consistency (α= 0.91) and split-half reliability (0.88) as was found in the full EHAS in the current study and prior validation. Concurrent validity existed between the EHAS-SF and measures of dysphagia (r= 0.33) and HRQOL (r = −0.73, both p<.001). The EHAS-SF is a 7-item scale to assess esophageal hypervigilance and symptom-specific anxiety that performs as well as the original 15-item version. Shorter questionnaires allow for implementation in clinical practice. The EHAS-SF is a useful tool for clinicians to quickly assess how hypervigilance and anxiety may be contributing to their patients’ clinical presentations.
