Abstract

The Boston Diagnostic Aphasia Examination (BDAE) has been extensively utilized in Serbia; however, data on its psychometric properties within this context are limited. This study aimed to evaluate the reliability and validity of the BDAE-2 in Serbian-speaking individuals with aphasia. The sample comprised 119 participants with stroke-induced aphasia and 51 neurologically healthy speakers. A Serbian translation of the second edition of the BDAE was administered to all participants. Findings indicated that the Serbian version of the BDAE-2 exhibited strong internal consistency, high inter-rater reliability, satisfactory construct validity, and robust discriminative capacity for differentiating individuals with aphasia from neurotypical speakers. Furthermore, specific subtests effectively distinguished between various aphasia types and demonstrated sensitivity to aphasia severity levels. Sociodemographic factors (gender, education, age) significantly influenced assessments of certain language abilities. In conclusion, the BDAE-2 was found to be a reliable diagnostic tool for assessing aphasia in Serbian speakers, showcasing favorable psychometric properties.

波士顿诊断性失语症检查（BDAE-2）在塞尔维亚人群中的信度和效度评价

波士顿失语诊断检查（BDAE）已在塞尔维亚广泛使用；然而，在这种情况下，关于其心理测量特性的数据是有限的。本研究旨在评估BDAE-2在塞尔维亚语失语症患者中的信度和效度。样本包括119名中风性失语症患者和51名神经系统健康的说话者。向所有与会者分发了第二版的塞尔维亚语翻译本。结果表明，塞尔维亚语版BDAE-2具有较强的内部一致性、较高的量表间信度、较好的构念效度和较强的区分失语症个体与神经正常说话者的能力。此外，特定的子测试有效地区分了各种失语症类型，并显示了对失语症严重程度的敏感性。社会人口因素（性别、教育程度、年龄）显著影响对某些语言能力的评估。综上所述，BDAE-2是评估塞尔维亚语失语症的可靠诊断工具，显示出良好的心理测量特性。
