There are currently no questionnaires to measure the knowledge of nurses about dementia or Alzheimer's disease care in the Spanish language.
To validate the Spanish version of the Dementia Knowledge Assessment Tool 2 (DKAT2-Sp).
The DKAT2 was translated into Spanish and then back-translated. The new Spanish version was validated in a sample of 361 members of the nursing staff from 24 nursing homes and a sample of 297 nursing students in Spain. Psychometric properties were assessed through an item analysis, a Rasch analysis, differential item functioning analysis, construct validity (known groups), and internal consistency (Cronbach's alpha).
The 21 items of the DKAT2-Sp fit the model well, showing a wide range of difficulty. Four items have differential items functioning between nursing professionals and students. The DKAT2-Sp shows acceptable internal consistency (Cronbach's alpha = 0.76 for nursing professionals and 0.83 for students). Scores obtained in the known groups test were as hypothesized (Nursing home staff mean = 15.57 versus Nursing student mean = 12.85; p < 0.0001 for mean difference), supporting construct validity.
The DKAT2-Sp is a reliable and valid questionnaire to measure knowledge about dementia in both nursing professionals and nursing students in Spanish-speaking contexts.
目前尚无西班牙语版的护士对痴呆症或阿尔茨海默病护理知识的问卷。
验证痴呆症知识评估工具 2 （DKAT2-Sp）的西班牙语版本。
DKAT2 被翻译成西班牙语，然后再被翻译回英语。新的西班牙语版本在西班牙 24 家养老院的 361 名护理人员样本和 297 名护理学生样本中进行了验证。通过项目分析、Rasch 分析、差异项目功能分析、结构效度（已知组）和内部一致性（Cronbach's alpha）评估心理测量特性。
DKAT2-Sp 的 21 个项目与模型拟合良好，显示出广泛的难度范围。有 4 个项目在护理专业人员和学生之间存在差异项目功能。DKAT2-Sp 具有可接受的内部一致性（护理专业人员的 Cronbach's alpha 为 0.76，学生为 0.83）。已知组测试中的得分与假设一致（养老院工作人员的平均得分为 15.57，护理学生的平均得分为 12.85；p<0.0001，平均值差异），支持结构效度。
DKAT2-Sp 是一种可靠和有效的问卷，可用于衡量西班牙语环境中护理专业人员和护理学生对痴呆症的知识。
