The aim of this study was to translate and validate the Alzheimer's Disease Knowledge scale (ADKS) in a population of Greek general practitioners (GPs). The international standards for the forward and back translation approach were followed. For the validation step, 112 GPs, treating dementia in their daily practices, were enrolled from Crete. The questionnaire was assessed for the following psychometric properties: intraclass reliability, test-retest reliability, and construct and face validity. Internal consistency of the Greek ADKS was satisfactory (α = .65). A high repeatability of the instrument was found during the retest with 27 GPs (intraclass correlation coefficient = 1.0). Factor analysis showed that all the items from the original instrument can be used in the Greek version. The inter-item correlation revealed a high cross-correlation between the items of the questionnaire (α > .6). The data confirmed the validity of the Greek version of the ADKS for measuring GPs' knowledge on the diagnosis and management of dementia.
本研究的目的是在希腊全科医生（GP）群体中翻译并验证阿尔茨海默病知识量表（ADKS）。遵循了正向和反向翻译方法的国际标准。在验证阶段，从克里特岛招募了112名在日常诊疗中治疗痴呆症的全科医生。对问卷进行了以下心理测量学特性评估：组内信度、重测信度以及结构效度和表面效度。希腊版ADKS的内部一致性令人满意（α = 0.65）。在对27名全科医生进行重测时发现该工具具有较高的重复性（组内相关系数 = 1.0）。因子分析表明，原始量表的所有项目均可用于希腊语版本。项目间相关性显示问卷项目之间存在高度交叉相关性（α > 0.6）。数据证实了希腊版ADKS在测量全科医生对痴呆症诊断和管理知识方面的有效性。
