Abstract

Objectives: The present article aims to identify the optimal cutoff score and the diagnostic accuracy for the English version of Speech Handicap Index (SHI) to screen out individuals with and without speech disorders in daily life.

Materials and methods: In this cross-sectional cohort study, a volunteer sample of 104 adult patients after total laryngectomy and 99 healthy controls in the United States completed the English version of SHI online questionnaire. Sensitivity and specificity were computed for a range of cut-off values using the Receiving Operating Characteristics (ROC) analysis to establish an optimal cutoff point for the SHI. Other measures of diagnostic accuracy, such as likelihood ratios (LR), positive predictive values (PPV), and negative predictive values (NPV) were also computed.

Results: Patients after total laryngectomy obtained a higher score than the healthy controls on the mean scores of SHI. According to the ROC analysis, an optimal cutoff score of 17 points determined by Youden index was identified on the head and neck cancer population with a sensitivity of 92.31%, specificity of 92.31%, PPV of 90.60%, NPV of 91.75%, LR + of 9.14, and LR- of 0.09.

Conclusions: The cutoff score of the English version of SHI applied on the English-speaking population in the United States demonstrated promising diagnostic accuracy.

对美国全喉患者英语版语言障碍指数分界点的调查。

研究目的本文旨在确定英文版言语障碍指数（SHI）的最佳临界值和诊断准确性，以筛选出日常生活中存在和不存在言语障碍的个体：在这项横断面队列研究中，美国的104名全喉切除术后成年患者和99名健康对照者自愿填写了英文版SHI在线问卷。使用接收操作特征（ROC）分析法计算了一系列临界值的灵敏度和特异性，以确定SHI的最佳临界点。此外，还计算了诊断准确性的其他指标，如似然比（LR）、阳性预测值（PPV）和阴性预测值（NPV）：全喉切除术后患者的SHI平均得分高于健康对照组。根据 ROC 分析，在头颈部癌症人群中，尤登指数确定的最佳临界值为 17 分，灵敏度为 92.31%，特异度为 92.31%，PPV 为 90.60%，NPV 为 91.75%，LR + 为 9.14，LR- 为 0.09：英文版 SHI 的临界值适用于美国的英语人群，诊断准确性良好。

期刊介绍： Logopedics Phoniatrics Vocology is an amalgamation of the former journals Scandinavian Journal of Logopedics & Phoniatrics and VOICE. The intention is to cover topics related to speech, language and voice pathology as well as normal voice function in its different aspects. The Journal covers a wide range of topics, including: Phonation and laryngeal physiology Speech and language development Voice disorders Clinical measurements of speech, language and voice Professional voice including singing Bilingualism Cleft lip and palate Dyslexia Fluency disorders Neurolinguistics and psycholinguistics Aphasia Motor speech disorders Voice rehabilitation of laryngectomees Augmentative and alternative communication Acoustics Dysphagia Publications may have the form of original articles, i.e. theoretical or methodological studies or empirical reports, of reviews of books and dissertations, as well as of short reports, of minor or ongoing studies or short notes, commenting on earlier published material. Submitted papers will be evaluated by referees with relevant expertise.
