目的：研究Northwick Park Dependency Scale（NPDS）的心理测量学特性。设计：回顾现有文献和心理测量学分析，并与一个大型神经康复队列中的其他标准化残疾指标进行比较。设置：英国伦敦的一个区域急性期后专科住院神经康复单位。参与者：共569名复杂神经残疾住院患者（350名男性，219名女性;平均年龄44.4岁）。主要措施：NPDS，Barthel指数，功能独立性和功能评估measurements.Results：数据库搜索发现5项研究，检查了NPDS的心理测量学。这些都支持了它的有效性和可靠性。本研究通过评估内部一致性、因素结构、辨别力和对康复过程中变化的反应来补充这些内容。发现NPDS具有良好的内部一致性（α =0.90），这表明它可以合理地加总为一个总分。它的歧视与不同程度的依赖，并响应变化，特别是在较高的依赖groups.Conclusion：NPDS是一个心理测量强大的工具，提供了更广泛的信息比其他一些常用的残疾措施的护理需求。特殊护理需求子量表提供了临床有用的信息，但其指标属性需要进一步开发，目前正在进行中。
Objective: To examine the psychometric properties of the Northwick Park Dependency Scale (NPDS).Design: Review of existing literature and psychometric analysis in relation to other standardized measures of disability in a large neurorehabilitation cohort.Setting: A regional post-acute specialist inpatient neurorehabilitation unit in London, UK.Participants: A total of 569 inpatients with complex neurological disabilities (350 males, 219 females; mean age 44.4 years).Main measures: The NPDS, Barthel Index, Functional Independence and Functional Assessment measures.Results: A database search found 5 studies that examined the psychometrics of the NPDS. These supported its validity and reliability. The present study added to these by evaluating the internal consistency, factor structure, discriminatory power and responsiveness to change during rehabilitation. The NPDS was found to have good internal consistency (alpha=0.90), suggesting that it can reasonably be summed to a single total score. It discriminated among people with different levels of dependency and was responsive to change, particularly in the higher dependency groups.Conclusion: The NPDS is a psychometrically robust tool, providing a broader range of information on nursing needs than some other commonly-used disability measures. The Special Nursing Needs subscale provides clinically useful information, but its metric properties require further development, which is now underway.
