To investigate the routine use of a measure of quality of life (QoL) in care homes and assess its psychometric properties when used by care staff.
A cross-sectional two-phase study.
Data were collected from care staff in seven care homes in East Sussex, England.
Phase I: The ability of care staff from two care homes to use the DEMQOL-Proxy without interviewer administration was assessed using agreement analysis between a self-administered and interviewer-administered version of the instrument. Based on these findings, DEMQOL-Proxy was adapted into a new version, DEMQOL-CH, for use as a self-administered instrument in care homes. We assessed agreement between the new DEMQOL-CH and DEMQOL-Proxy to ensure DEMQOL-CH was used correctly. Phase II: A preliminary assessment of the psychometric properties of DEMQOL-CH when used routinely was completed in a further five care homes.
Phase I: Nineteen care staff from two care homes completed QoL measurements for residents. Systematic error was identified when staff self-completed the DEMQOL-Proxy without an interviewer. We modified the DEMOoL-Proxy to create DEMQOL-CH; this reduced the error, producing a version that could be used more accurately by care staff. Phase II: Eleven care staff from five care homes rated resident QoL routinely. DEMQOL-CH showed acceptable psychometric properties with satisfactory reliability and validity and a clear factor structure.
The research presents positive preliminary data on the acceptability, feasibility and performance of routine QoL measurement in care homes using an adapted version of DEMQOL-Proxy, the DEMQOL-CH. Results provide evidence to support the concept that routine measurement of QoL may be possible in care homes. Research is needed to refine and test the methodology and instrument further and to explore the potential for benefits to residents, staff and care homes in larger and more representative populations.
调查护理院中生活质量（QoL）测量方法的常规使用情况，并评估护理人员使用该方法时的心理测量特性。
一项横断面两阶段研究。
数据收集自英国东萨塞克斯郡七家护理院的护理人员。
第一阶段：通过对该工具的自我施测版本和访谈员施测版本进行一致性分析，评估两家护理院的护理人员在无访谈员协助的情况下使用DEMQOL-Proxy的能力。基于这些结果，将DEMQOL-Proxy改编为新版本DEMQOL-CH，用作护理院中自我施测的工具。我们评估了新的DEMQOL-CH与DEMQOL-Proxy之间的一致性，以确保DEMQOL-CH的使用正确。第二阶段：在另外五家护理院中对DEMQOL-CH常规使用时的心理测量特性进行了初步评估。
第一阶段：两家护理院的19名护理人员完成了对居民的生活质量测量。当护理人员在无访谈员的情况下自行完成DEMQOL-Proxy时，发现了系统误差。我们对DEMQOL-Proxy进行了修改，创建了DEMQOL-CH；这减少了误差，产生了一个护理人员可以更准确使用的版本。第二阶段：五家护理院的11名护理人员对居民生活质量进行了常规评分。DEMQOL-CH显示出可接受的心理测量特性，具有令人满意的信度和效度以及清晰的因子结构。
该研究提供了关于使用改编版DEMQOL-Proxy即DEMQOL-CH在护理院中进行常规生活质量测量的可接受性、可行性和性能的积极初步数据。结果提供了证据支持护理院中可能进行生活质量常规测量的概念。需要进一步开展研究以完善和测试该方法及工具，并在更大规模和更具代表性的人群中探索对居民、工作人员和护理院的潜在益处。
