The Krogh-Poulsen Test is a classic instrument to measure dysfunction of the stomatognathic system whose psychometric properties are unknown. This study aimed to evaluate the psychometric properties of the Krogh-Poulsen Test for the diagnosis of temporomandibular disorders (TMDs). A cross-sectional study was designed, including 119 patients (63 patients with TMD and 56 healthy controls). Factorial validity, inter-rater reliability, error of measurement, diagnostic validity of the Krogh-Poulsen Test, and concurrent validity were analyzed. The Krogh-Poulsen Test showed a three-factor structure. The inter-rater agreement could be considered very good with a kappa index of 0.87 (95% CI 0.83-0.90) and Standard Error of Measurement of 0.79. Correlations were strong with other orofacial instruments, moderate with instruments measuring TMD-related disorders such as neck pain, headache, or dizziness, and poor with generic quality of life instruments. The Area Under the Curve ROC was 0.928 showing, for a cut-off point >1, a sensitivity of 90.48 (95% CI 80.4-96.4) and a specificity of 85.71 (95% CI 73.8-93.6) for the diagnosis of TMD disorders. The Krogh-Poulsen Test showed a three-factor structure, very good inter-rater reliability, a strong correlation with other orofacial instruments, and an excellent capacity to discriminate between patients with or without TMD.
克罗格 - 波尔森测试是一种用于测量口颌系统功能障碍的经典工具，但其心理测量特性尚不清楚。本研究旨在评估克罗格 - 波尔森测试在颞下颌关节紊乱病（TMD）诊断中的心理测量特性。设计了一项横断面研究，纳入119名患者（63名TMD患者和56名健康对照）。分析了克罗格 - 波尔森测试的因子效度、评分者间信度、测量误差、诊断效度和同时效度。克罗格 - 波尔森测试呈现出三因素结构。评分者间一致性可认为非常好，kappa指数为0.87（95%CI 0.83 - 0.90），测量标准误为0.79。与其他口腔颌面部工具的相关性很强，与测量TMD相关疾病（如颈部疼痛、头痛或头晕）的工具相关性中等，与一般生活质量工具的相关性较差。曲线下面积（ROC）为0.928，对于截断点>1，诊断TMD疾病的灵敏度为90.48（95%CI 80.4 - 96.4），特异度为85.71（95%CI 73.8 - 93.6）。克罗格 - 波尔森测试呈现出三因素结构，评分者间信度非常好，与其他口腔颌面部工具相关性很强，并且在区分有无TMD患者方面具有出色的能力。
