SummaryBackgroundAchalasia is a debilitating major motor disorder of the oesophagus. Hypervigilance and symptom‐specific anxiety substantially impact dysphagia symptom reporting, and quality of life is a critical patient outcome. Earlier achalasia symptom scales did not consider these constructs in their psychometric development.AimTo develop a new symptom measure, the Achalasia Patient‐Reported Outcomes (APRO) QuestionnaireMethodsFour gastroenterologists with achalasia expertise generated preliminary items. Patients reviewed items via cognitive interviews. Patients undergoing high‐resolution manometry completed the APRO with Oesophageal Hypervigilance and Anxiety Scale, Northwestern Oesophageal Quality of Life Scale, and three measures of reflux and dysphagia. Full APRO psychometric assessment (reliability, validity, factor structure) was done. Cluster analysis evaluated APRO + symptom‐anxiety/hypervigilance patient phenotypes.ResultsWe included 961 patients with normal motility and 296 with achalasia. The APRO yielded three subscales: dysphagia, reflux, chest pain with two items for weight change and diet modifications. Reliability and validity were excellent. Twenty‐five percent of achalasia patients may have high levels of anxiety/hypervigilance despite low symptoms, while 8% may report severe symptoms with low anxiety/hypervigilance. The APRO significantly predicted quality of life, but less cognitive‐affective processes.ConclusionsThe APRO is a reliable and valid measure of achalasia symptoms that addresses the limitations of existing questionnaires. Symptom anxiety and hypervigilance moderate the relationship between APRO and quality of life; 33% of patients with achalasia exhibit concerning patterns in symptom severity, anxiety and hypervigilance that may contribute to poorer outcomes.

OBJECTIVES: Symptoms are inconsistently associated with esophageal motor findings on high-resolution manometry (HRM). We aimed to evaluate predictors of dysphagia severity, including esophageal hypervigilance and visceral anxiety, among patients evaluated with HRM. METHODS: Adult patients undergoing HRM at 4 academic medical centers (United States and France) were prospectively evaluated. HRM was completed and analyzed per the Chicago Classification v3.0. Validated symptom scores, including the Brief Esophageal Dysphagia Questionnaire and Esophageal Hypervigilance and Anxiety Scale, were completed at the time of HRM. RESULTS: Two hundred thirty-six patients, aged 18–85 (mean 53) years, 65% female, were included. Approximately 59 (25%) patients had a major motor disorder on HRM: 19 achalasia, 24 esophagogastric junction outflow obstruction, 12 absent contractility, and 4 jackhammer. Approximately 177 (75%) patients did not have a major motor disorder: 71 ineffective esophageal motility and 106 normal motility. Having a major motor disorder was a significant predictor of dysphagia severity (R 2 adj = 0.049, P < 0.001), but the Esophageal Hypervigilance and Anxiety Scale score carried a predictive relationship of Brief Esophageal Dysphagia Questionnaire that was 2-fold higher than having a major motor disorder: R 2 adj = 0.118 ( P < 0.001). This finding remained when evaluated by the major motor disorder group. HRM metrics were nonsignificant. DISCUSSION: In a prospective, international multicenter study, we found that esophageal hypervigilance and visceral anxiety were the strongest predictors of dysphagia severity among patients evaluated with HRM. Thus, an assessment of esophageal hypervigilance and visceral anxiety is important to incorporate when evaluating symptom severity in clinical practice and research studies.
