背景由于在呼叫中心等行业中嗓音健康风险增加，因此需要有可访问的、快速的语音症状自我报告工具。本研究旨在确定语音质量和症状的三个视觉模拟量表(VASS)的同时效度和结构效度是否可以作为呼叫中心话务员的筛查工具。对66名呼叫中心工作人员进行了语音障碍指数-10(VHI-10)和发声卫生和症状调查。此外，还收集了包括谐波噪声比(HNR)、平滑倒谱峰值显著(CPPS)、L1-L0斜率和Alpha比在内的声学参数。最后，工作人员完成了三项VASS，分别捕捉了发声努力自我知觉(VAS-1)、声音质量(VAS-2)和发声疲劳(VAS-3)。结果VAS-1评分与HNR和嗓音中断有关，VAS-2评分与嗓音中断相关，VAS-3评分与α比相关。使用受试者工作特征曲线下的面积(AUC)，观察到三种VAS在检测VHI-10问卷分数改变时的AUC最高。VAS-1检测CPP改变的AUC最高。结论VAS作为一种发声症状的自我报告工具，与呼叫中心工作人员的心理社会嗓音障碍和声学嗓音参数的改变有关。这类仪器可以很容易地在这些人群中识别语音抱怨。证据水平2(诊断研究问题)喉镜，133：1676-1682,2023
BackgroundDue to elevated vocal health risk in industries such as call centers, there is a need to have accessible and quick self‐report tools for voice symptoms. This study aimed to determine if the concurrent and construct validity of three visual analog scales (VASs) of voice quality and symptoms could be used as a screening tool in call center agents.MethodsA cross‐sectional study was carried out in three call center companies. The Voice Handicap Index‐10 (VHI‐10) and a vocal hygiene and symptoms survey were administered to 66 call center workers. Further, acoustic parameters including harmonics‐to‐noise ratio (HNR), smoothed cepstral peak prominence (CPPs), L1‐L0 slope, and Alpha ratio were collected. Finally, workers completed three VASs capturing self‐perception of vocal effort (VAS‐1), voice quality (VAS‐2), and vocal fatigue (VAS‐3). Linear regression models with bootstrapping evaluated the possible relationship between the three VASs measurements, self‐perceived vocal symptoms, and acoustic parameters.ResultsVAS‐1 scores were associated with HNR and voice breaks, VAS‐2 with voice breaks, and VAS‐3 with Alpha ratio. Using the area under a receiver operating characteristic curve (AUC), the highest AUC for detecting an altered VHI‐10 questionnaire score was observed for the three VASs. Also, the highest AUC for detecting altered CPPs was reached for the VAS‐1.ConclusionsVAS as a self‐report instrument of vocal symptoms is related to psychosocial voice impairment and alterations of acoustic voice parameters in call center workers. Such instruments could be easily implemented to identify voice complaints in these populations.Level of Evidence2 (Diagnosis research question)Laryngoscope, 133:1676–1682, 2023
