居家状态是医疗保险报销的一些家庭护理服务的一个关键的资格标准，但很少有讨论已经进行了建立一个有效的definitionofit.We提出了一个可操作的定义居家状态，我们衡量其有效性社区居住的老年人在马萨诸塞州卫生保健小组研究（MHCPS）。MHCPS是一项对老年人队列（N = 1，625）的纵向研究，始于1974年，并于1976年，1980年和1985年进行了随访调查。有效性是通过比较从操作措施的人的问题，我们认为应该与一个有效的措施，居家状态的反应。这种结构有效性方法导致相关性是显着的，在预期的方向，这表明，这种操作措施是一个高度具体的，适度的敏感性，有效的措施。这些结果强调了研究人员调查的必要性，讨论他们的家庭措施的有效性和局限性，以及在什么情况下，这些措施是有用的。
Homebound status is a critical eligibility criterion for Medicare reimbursement of some home care services, yet little discussion has been undertaken to establish a valid definition of it. We propose an operational definition of homebound status, and we measure its validity for community-dwelling elderly in the Massachusetts Health Care Panel Study (MHCPS). The MHCPS is a longitudinal study of a cohort of elderly persons (N = 1,625), which began in 1974, with follow-up surveys in 1976, 1980, and 1985. Validity was measured by comparing responses from the operational measure to persons' responses to questions that we judged should be associated with a valid measure of homebound status. This construct validity method resulted in correlations that were significant and in the expected direction, and that suggested that this operational measure is a highly specific, moderately sensitive, valid measure. These results underscore the need for researchers investigating the homebound to discuss the validity and limitations of their homebound measures, and in what context these measures are useful.
