One hundred and five consecutive patients attending an ENT out-patients' clinic with a diagnosis of globus pharyngis completed a 10-item questionnaire concerning common throat symptoms. Principal components analysis of the questionnaire revealed a general throat pathology factor, and three orthogonal rotated factors which were related to dysphagia, globus sensation, and pain/swelling in the throat. Of 10 throat symptoms, the globus patients most commonly complained of: "Feeling of something stuck in the throat," "Discomfort/irritation in the throat," and "Want to swallow all the time." These were the symptoms which had highest loadings on the 'globus' factor. The clear factor structure and the satisfactory internal consistency of the Glasgow-Edinburgh Throat Scale (GETS) suggest that it offers a clinically useful instrument for assessing and monitoring the severity of some common throat ailments. The degree of distress caused by throat symptoms was predicted independently by the intensity of the globus sensation and by anxiety level.
105名连续就诊于耳鼻喉科门诊且诊断为咽异感症的患者完成了一份关于常见咽喉症状的10项问卷。对该问卷进行主成分分析，发现了一个一般咽喉病理因素，以及与吞咽困难、咽异感和咽喉疼痛/肿胀相关的三个正交旋转因子。在10种咽喉症状中，咽异感症患者最常抱怨的是：“感觉有东西卡在喉咙里”、“喉咙不适/刺激感”以及“总想吞咽”。这些是在“咽异感”因子上负荷最高的症状。格拉斯哥 - 爱丁堡咽喉量表（GETS）清晰的因子结构和令人满意的内部一致性表明，它为评估和监测一些常见咽喉疾病的严重程度提供了一种临床有用的工具。咽喉症状引起的痛苦程度由咽异感的强度和焦虑水平独立预测。
