To assess the agreement between postal and interviewer-administered versions of the Frenchay Activities Index (FAI) and to assess the criterion validity of the postal version, using interviewer administration as a gold standard.
Comparison of responses to FAI administered by post and then by interview (median delay 10 days).
Forty-eight Oxfordshire residents admitted to hospital with acute stroke between 1 August 1994 and 31 January 1995 and discharged alive within six months of their stroke.
The limits of agreement of the total FAI score are from -5.4 to 7.2. The kappa statistic for each of the 15 individual items that make up the FAI ranged from 0.35 to 1. For nine items, agreement was moderate or fair, and for six items, agreement was good or very good. The mean difference between the overall scores was 0.9 (95% confidence interval: -0.1 to 1.9). The correlation between the overall scores was 0.94 (Spearman's rank correlation coefficient).
The postal version of the FAI is a satisfactory alternative to direct administration, but poor agreement in scores for individual patients emphasizes that the two approaches should not be used sequentially to monitor individual patients.
以访谈者施测作为金标准，评估法国ay活动指数（FAI）邮寄版和访谈者施测版之间的一致性，并评估邮寄版的效标效度。
比较先通过邮寄然后通过访谈施测FAI的反应（中位间隔时间10天）。
1994年8月1日至1995年1月31日期间因急性中风入住牛津郡医院且中风后6个月内存活出院的48名居民。
FAI总分的一致性界限为-5.4至7.2。构成FAI的15个单项的kappa统计量范围为0.35至1。9个项目的一致性为中等或尚可，6个项目的一致性为良好或非常好。总体得分的平均差异为0.9（95%置信区间：-0.1至1.9）。总体得分之间的相关性为0.94（斯皮尔曼等级相关系数）。
FAI邮寄版是直接施测的一种令人满意的替代方法，但个体患者得分的一致性较差，这强调不应依次使用这两种方法来监测个体患者。
