The Fonseca Anamnestic Index (FAI) offers a simple method to screen temporomandibular disorders (TMD). This study aimed to validate the Spanish version of the FAI in patients with TMD.
The sample consisted of 125 subjects (66 TMD and 59 controls) aged over 18 years. Construct validity, internal consistency, test-retest reliability, concurrent validity and capacity to discriminate between TMD and healthy subjects were analyzed.
The Spanish version of the FAI showed a structure formed by three factors. Cronbach's alpha was 0.826. The reliability of the items varied between substantial to almost perfect and was excellent for the total score (intraclass correlation coefficient = 0.937). The standard error of measurement (SEM) was 6.52, with a minimum detectable change (MDC) of 12.78. FAI score showed a significant correlation with headache, neck pain and vertigo measurements. A cut-off point >35 showed a sensitivity = 83.33% and a specificity = 77.97% in differentiating between healthy and TMD patients, with an area under the curve (AUC) = 0.865.
The Spanish version of the FAI is a valid and reliable instrument for diagnosing people with TMD, with appropriate general clinimetric properties. Discrimination between patients with and without TMD is excellent.
丰塞卡记忆指数（FAI）提供了一种筛查颞下颌关节紊乱病（TMD）的简单方法。本研究旨在验证FAI西班牙语版在TMD患者中的有效性。
样本包括125名年龄超过18岁的受试者（66名TMD患者和59名对照）。分析了结构效度、内部一致性、重测信度、同时效度以及区分TMD患者和健康受试者的能力。
FAI西班牙语版显示由三个因素构成的结构。克朗巴哈系数为0.826。各项目的信度在高到几乎完美之间变化，总分的信度极佳（组内相关系数 = 0.937）。测量标准误（SEM）为6.52，最小可检测变化（MDC）为12.78。FAI评分与头痛、颈部疼痛和眩晕测量值显著相关。在区分健康人和TMD患者时，截断点>35显示敏感性 = 83.33%，特异性 = 77.97%，曲线下面积（AUC） = 0.865。
FAI西班牙语版是一种有效且可靠的用于诊断TMD患者的工具，具有适当的一般临床测量特性。区分有TMD和无TMD患者的能力极佳。
