This study examined the concordance of two reporting methods for falls (3 month and 12 month recall) experienced by elderly living in a rural community. Four interview surveys on the occurrence of falls over a 3 month period were conducted from 1992 to 1993 every three months. In the final interview, subjects were also asked about the occurrence of falls during the past 12 months. A total of 799 subjects (270 men, 529 women) aged 65 and over, living in a village of Niigata Prefecture, responded to all four surveys. The incidence of falls in one year was 19.0% by the 3 month recall, and 19.1% by the 12 month recall. Overall agreement of fall occurrence between the two methods was 98.9%, and a coefficient of kappa as a measure of concordance was 0.96. On the other hand, subjects who sustained injuries during falls reported in the 3 month reporting did not necessarily recall having a fall when interviewed at the end of the study. In any case, this study reveals that for surveying falls by the elderly living in the community a 1 year recall is a reliable method, because of the high agreement of fall occurrence when comparing the two methods.
本研究调查了农村社区老年人跌倒两种报告方法（3个月和12个月回顾）的一致性。1992年至1993年期间，每三个月进行一次为期3个月的跌倒发生情况的四次访谈调查。在最后一次访谈中，还询问了受试者过去12个月内的跌倒情况。居住在新潟县一个村庄的799名65岁及以上的受试者（270名男性，529名女性）对所有四次调查都做出了回应。通过3个月回顾法得出的一年跌倒发生率为19.0%，通过12个月回顾法得出的为19.1%。两种方法之间跌倒发生情况的总体一致性为98.9%，作为一致性度量的kappa系数为0.96。另一方面，在3个月报告中报告跌倒时受伤的受试者在研究结束接受访谈时不一定记得自己跌倒过。无论如何，本研究表明，对于社区老年人跌倒情况的调查，1年回顾法是一种可靠的方法，因为比较两种方法时跌倒发生情况的一致性很高。
