Standardized clinical assessment of dysarthria is essential for management and research. We present a new, fully standardized dysarthria assessment, the Bogenhausen Dysarthria Scales (BoDyS). The measurement model of the BoDyS is based on auditory evaluations of connected speech using 9 scales (traits) assessed by 4 elicitation methods. Analyses of the BoDyS' reliability and construct validity were performed to test this model, with the aim of gauging the auditory dimensions of speech impairment in dysarthria.
Interrater agreement was examined in 70 persons with dysarthria. Construct validity was examined in 190 persons with dysarthria using a multitrait-multimethod design with confirmatory factor analysis.
Interrater agreement of < 1 on a 5-point scale was found in 91% of cases across listener pairs and scales. Average reliability was .85. Inspection of the multitrait-multimethod matrix pointed at a high convergent and discriminant validity. Modeling of the BoDyS trait and method factors using confirmatory factor analysis yielded high goodness of fit. Model coefficients confirmed high discriminant and convergent validity and revealed meaningful relationships between scales and methods.
The 9 auditory scales of the BoDyS provide a reliable and valid profile of dysarthric impairment. They permit standardized measurement of clinically relevant dimensions of dysarthric speech.
构音障碍的标准化临床评估对于管理和研究至关重要。我们提出了一种全新的、完全标准化的构音障碍评估方法，即博根豪森构音障碍量表（BoDyS）。BoDyS的测量模型基于对连贯言语的听觉评估，使用4种诱发方法评估9个量表（特征）。对BoDyS的信度和结构效度进行了分析以检验该模型，目的是衡量构音障碍中言语损伤的听觉维度。
对70名构音障碍患者进行了评分者间一致性检验。使用多特征-多方法设计和验证性因素分析，对190名构音障碍患者进行了结构效度检验。
在91%的病例中，跨听者对和量表的5分制评分者间一致性小于1。平均信度为0.85。对多特征-多方法矩阵的检查表明具有较高的收敛效度和区分效度。使用验证性因素分析对BoDyS特征和方法因素进行建模，得到了较高的拟合优度。模型系数证实了较高的区分效度和收敛效度，并揭示了量表与方法之间有意义的关系。
BoDyS的9个听觉量表提供了构音障碍损伤的可靠且有效的概况。它们允许对构音障碍言语的临床相关维度进行标准化测量。
