使用访谈数据来衡量健康状况的工具已越来越多地用于衡量患者的结果。为了评估当受试者无法做出回应时，代理人对健康状况的反应的潜在效用，作者比较了60名受试者和代理人对测量整体当前健康状况，功能状态，社会活动，情绪健康和医疗服务满意度的工具的反应。代理人被要求按照他们认为的主题做出回应。受试者和代理人的回答与整体健康，功能状态，社会活动和情绪健康密切相关（P<0.05）。001），与满意度中度相关（P<. 005）。代理人的情绪健康和满意度低于受试者（P<. 005）。代理人和受试者的总体健康状况、功能状态和社会活动的平均应答通常相似。然而，那些每周花更多时间帮助受试者的代理人认为受试者的功能状态和社会活动比受试者更受损（P<0.05）。05）。总体健康状况较差的受试者倾向于对自己的健康状况的评价相对低于代理人（P<0.05）。05）。这些结果表明，使用代理人与主题混合，以衡量健康状况，通过采访可能会导致偏颇的结果。
Instruments using interview data to measure health status have been increasingly used to measure patient outcomes. To assess the potential utility of proxy responses about health status when subjects are unable to respond, the authors compared the responses of 60 subject and proxy pairs on instruments measuring overall current health, functional status, social activity, emotional health, and satisfaction with medical care. Proxies were asked to respond as they thought the subject would. Subject and proxy responses were strongly correlated with each other for overall health, functional status, social activity, and emotional health (P<. 001), and moderately correlated for satisfaction (P<. 005). Proxies reported lower emotional health and satisfaction than did subjects (P<. 005). Proxy and subject mean responses were generally similar for overall health, functional status, and social activity. However, those proxies who spent more time per week helping the subject rated the subject's functional status and social activity as more impaired than did the subject (P<. 05). Subjects who had poorer overall health tended to rate their health relatively lower than did the proxies (P<. 05). These results suggest that use of proxies intermingled with subjects to measure health status through interview may lead to biased results.
