OBJECTIVE: To measure the inter-rater reliability of the interview-administered version of the Frenchay Activities Index (FAI). DESIGN: Comparison of FAI score on the same person when administered by two raters (mean time between interviews 15.2 days). SUBJECTS: Fifty-nine Oxfordshire residents who either had had a stroke (n = 35) or were the main carer (n = 24). RESULTS: The 95% limits of agreement for the FAI totals were -9.9 to +8.4. The kappa statistic for nine of the 15 items showed a good level of agreement between the two research interviews (0.64-0.80). The other six items showed fair or moderate strength of agreement (0.26-0.52). Three items showed significant differences between the two raters p < 0.05 (Wilcoxon's sign paired rank sum test). The mean difference between the total scores was -0.76 (95% confidence interval from -1.98 to 0.46). Spearman's rho correlation coefficient for FAI totals of rater B against A was r(59) = 0.93 (p < 0.001). CONCLUSION: The FAI is a reliable tool for measuring outcome following stroke. Suggestions are made to strengthen the reliability, and consequently the validity of the measure.
