Reliability and validity of the German version of the Glasgow Edinburgh Throat Scale

Background Many patients who consult the ENT doctor suffer from globus sensation, as a term for a multifactorial symptom description. It is particularly important during initial consultation to take the often-sensitive patients seriously and to offer a structured diagnostic clarification. Today, there is a lack of a screening tool in everyday clinical practice that can be used to differentiate the globus sensations more closely and assess their severity Objectives The reliability and validity of the German version of the Glasgow Edinburgh Throat Scale (GETS) were examined. Materials und Methods The original GETS questionnaire was translated into German (GETS-G) and completed by 60 patients with globus sensation (>3 months) in a prospective observational study. All patients received a clinical examination a sonography of the neck. In patients without an identifiable organic cause, a pH monitoring was carried out. Results A local organic cause for the globus sensation was found in 30 patients (50%). In addition, reflux was detected in 24 patients (40%) using pH monitoring. No cause could be determined in only 6 patients (10%). According to the overall score (Q1-Q12), there was no significant difference between these three groups. The Cronbach's alpha for assessing reliability was 0.88 in the 12-item analysis. Principal component analysis yielded a globus scale, dysphagia scale and a chronic pharyngeal irritation scale. Conclusions The GETS-G showed high reliability and validity, which justifies its use in patients with globus sensation in German-speaking countries and may lead to a better assessment of the severity of this symptom.
