The visuoperceptual measure for videofluoroscopic swallow studies (VMV) is a new measure for analysing the recordings from videofluoroscopic swallow studies (VFSS). This study evaluated the reliability and validity of the pilot version of the VMV using classical test theory (CTT) analysis, informed by the consensus-based standards for the selection of health measurement instruments (COSMIN) guidelines. Forty participants, diagnosed with oropharyngeal dysphagia by fibreoptic endoscopic evaluation of swallowing, were recruited. The VFSS and administration of bolus textures and volumes were conducted according to a standardised protocol. Recordings of the VFSS were rated by three blinded raters: a speech-language pathologist, a radiologist and a phoniatrician. Inter- and intra-rater reliability was assessed with a weighted kappa and resulted in 0.889 and 0.944 overall, respectively. Structural validity was determined using exploratory factor analyses, which found four and five factor solutions. Internal consistency was evaluated with Cronbach's alpha coefficients, which found all but one factor scoring within an acceptable range (>0.70 and <0.95). Hypothesis testing for construct validity found the expected correlations between the severity of dysphagia and the VMV's performance, and found no impact of gender on measure performance. These results suggest that the VMV has potential as a reliable and valid measure for VFSS. Further validation with a larger sample is required, and validation using an item response theory paradigm approach is recommended.
用于电视荧光吞咽造影研究的视觉感知测量法（VMV）是一种分析电视荧光吞咽造影研究（VFSS）记录的新方法。本研究采用经典测试理论（CTT）分析，依据基于共识的健康测量工具选择标准（COSMIN）指南，评估了VMV试用版的信度和效度。招募了40名经纤维内镜吞咽评估诊断为口咽吞咽困难的参与者。VFSS以及团块质地和体积的施用均按照标准化方案进行。VFSS的记录由三名不知情的评分者进行评分：一名言语病理学家、一名放射科医生和一名语音治疗师。评分者间信度和评分者内信度通过加权kappa系数进行评估，总体结果分别为0.889和0.944。使用探索性因素分析确定结构效度，发现了四因素和五因素解决方案。使用克朗巴赫α系数评估内部一致性，发现除一个因素外，所有因素的得分均在可接受范围内（>0.70且<0.95）。对构想效度进行假设检验，发现吞咽困难严重程度与VMV表现之间存在预期的相关性，且发现性别对测量表现没有影响。这些结果表明，VMV有潜力成为一种用于VFSS的可靠且有效的测量方法。需要用更大的样本进行进一步验证，建议使用项目反应理论范式方法进行验证。
