Raising understanding of dementia has become a key focus of international health and social care. An up-to-date, psychometrically sound measure of dementia knowledge that embraces a biopsychosocial perspective is lacking. The aim of this study is to develop and evaluate the psychometric properties of the DK-20, a dementia knowledge questionnaire aimed at unqualified care staff.
Domain and item generation followed recommended measure development procedures. A pilot and large-scale study evaluated the psychometric properties of the measure on a sample of 211 care staff and other dementia professionals.
The final 20-item measure encompasses items based on biopsychosocial dementia knowledge and care-specific knowledge. Acceptable test-retest reliability, marginal levels of internal consistency, and evidence for face, content, and construct validity were demonstrated.
The DK-20 is the first knowledge of dementia measure to be developed specifically for unqualified care staff and has reasonable psychometric properties. It may be used to identify gaps in knowledge, highlighting areas for inclusion in educational interventions.
提高对痴呆症的认识已成为国际卫生和社会保健的一个重点。目前缺乏一种最新的、具有心理测量学效度的、涵盖生物心理社会视角的痴呆症知识衡量标准。本研究旨在开发和评估 DK-20 的心理测量特性，这是一种针对非专业护理人员的痴呆症知识问卷。
遵循推荐的测量开发程序进行领域和项目生成。一项试点研究和一项大规模研究在 211 名护理人员和其他痴呆症专业人员样本中评估了该测量的心理测量特性。
最终的 20 项测量涵盖了基于生物心理社会痴呆症知识和特定于护理的知识的项目。测试-重测信度可接受，内部一致性的边缘水平，以及有充分的表面、内容和结构效度的证据。
DK-20 是专门为非专业护理人员开发的第一个痴呆症知识衡量标准，具有合理的心理测量特性。它可用于确定知识差距，突出纳入教育干预的领域。
