Achalasia Quality of Life (ASQ) and Eckardt scores are two patient-reported instruments widely used to assess symptom severity in achalasia patients. ASQ is validated and reliable. Although Eckardt is commonly used, it has not been rigorously assessed for validity or reliability. This study aims to evaluate (i) the accuracy of Eckardt and ASQ for assessing improvement post-treatment (predictive validity), (ii) accuracy of Eckardt and ASQ for assessing improvement post-treatment with pneumatic dilatation (PD) versus surgical myotomy (predictive validity), and (iii) convergent validity of Eckardt and ASQ tools.
