A demonstration respite project for caregivers of older people with Alzheimer's disease was evaluated by a randomized experiment. Three hundred and sixteen volunteer primary caregivers were offered respite services and 315 completed the research portion without the offer of respite. The research indicated that even before the demonstration most families had some respite help in place. Of all those offered respite, 58% availed themselves of the offer. During the project year experimental and control subjects were equal in using slightly more services and there was no evidence that formal services had substituted for informal.
一项针对老年痴呆症患者照料者的示范性喘息服务项目通过随机试验进行了评估。316名志愿主要照料者获得了喘息服务，315名未获得喘息服务的照料者完成了研究部分。研究表明，甚至在示范项目开展之前，大多数家庭就已经有了一些喘息帮助。在所有获得喘息服务的人中，58%利用了这一服务。在项目实施的这一年里，实验组和对照组在使用稍多服务方面情况相当，而且没有证据表明正规服务取代了非正规服务。
