To evaluate the inter-rater reliability and predictive validity of the Frenchay Activities Index (FAI) in patients after stroke.
One hundred sixty-one patients were selected for consecutive application of the FAI and National Institutes of Health Stroke Scale (NIHSS). Spearman's test was used for correlation between different scales. The FAI and NIHSS association was evaluated using ordinal logistic regression. Additionally, 36 patients underwent FAI rating on the same day by two independent evaluators.
A negative correlation between the FAI and the NIHSS scores (p = 0.017 r = -0.22) was found. Adjusting all variables with possible association with the NIHSS, ordinal logistic regression showed that the FAI had a significant association with NIHSS scores (OR 0.93, 95% CI 0.87 to 0.99, p: 0.033). The inter-rater agreement was considered good, k = 0.66 (0.54 to 0.78), p < 0.001.
The FAI is a valid and useful method to assess instrumental activities before acute stroke in a Brazilian population.
评估法国ay活动指数（FAI）在中风患者中的评分者间信度和预测效度。
选取161例患者连续应用FAI和美国国立卫生研究院卒中量表（NIHSS）。采用Spearman检验分析不同量表之间的相关性。使用有序逻辑回归评估FAI与NIHSS的关联。此外，36例患者由两名独立评估者在同一天进行FAI评分。
发现FAI与NIHSS评分呈负相关（p = 0.017，r = -0.22）。对所有可能与NIHSS相关的变量进行调整后，有序逻辑回归显示FAI与NIHSS评分有显著关联（OR 0.93，95%CI 0.87至0.99，p：0.033）。评分者间一致性良好，k = 0.66（0.54至0.78），p < 0.001。
FAI是评估巴西人群急性中风前工具性活动的有效且有用的方法。
