Background

SATIS-Stroke questionnaire has been translated and adapted for use in the Brazilian population, however, it is necessary to test the measurement properties in Brazilian population.

Objective

To test the reliability, agreement, concurrent validity, and diagnostic accuracy of the SATIS-Stroke.

Methods

Chronic stroke survivors were included. The calculations were made using scores in logits (Rasch Model). Reliability was tested using the intraclass correlation coefficient (ICC_2,1), standard error of measurement (SEM), minimal detectable change (MDC), and Bland-Altman plots. Concurrent validity was analyzed using Spearman's correlation coefficient. For such, the correlation between SATIS-Stroke and Stroke Specific Quality of Life (SS-QOL) questionnaires was determined. Diagnostic accuracy was estimated based on the area under the receiver operating characteristic (ROC) curve with a 95% confidence interval and considering the sensitivity and specificity of SATIS-Stroke in differentiating different types of activity and participation.

Results

Eighty stroke survivors were analyzed. Mean age was 57.98±13.85 years and 45.2% had severe impairment. Excellent reliability was found (intra-observer ICC_2,1 = 0.90; 95% CI: 0.84, 0.93; inter-observer ICC_2,1 = 0.89; 95% CI: 0.83, 0.93). The Bland-Altman plot demonstrated satisfactory agreement. In the analysis of concurrent validity, a strong, positive, significant correlation was found between SATIS-Stroke and SS-QOL (r_s = 0.74; p <0.001 with an r²=0.44; p=0.001). Diagnostic accuracy was satisfactory, with 80.8% sensitivity and 85.2% specificity.

Conclusion

The Brazilian version of the SATIS-Stroke questionnaire exhibited adequate reliability, concurrent validity, and diagnostic accuracy. Therefore, this is a valid, reproducible measure for the assessment of satisfaction with regard to activities and participation following a stroke.

巴西人群中 SATIS-中风问卷的临床测量特性：针对中风后活动和参与的满意度评估措施

背景

SATIS-中风问卷已被翻译并改编用于巴西人口，但是，有必要测试巴西人口的测量特性。

客观的

测试 SATIS-Stroke 的可靠性、一致性、同时有效性和诊断准确性。

方法

慢性中风幸存者也被包括在内。使用对数分数（Rasch 模型）进行计算。使用组内相关系数 (ICC _2,1 )、测量标准误差 (SEM)、最小可检测变化 (MDC) 和 Bland-Altman 图来测试可靠性。使用 Spearman 相关系数分析同时有效性。为此，确定了 SATIS-中风和中风特定生活质量 (SS-QOL) 问卷之间的相关性。根据置信区间为 95% 的受试者工作特征 (ROC) 曲线下面积，并考虑 SATIS-Stroke 在区分不同类型的活动和参与方面的敏感性和特异性，估计诊断准确性。

结果

对八十名中风幸存者进行了分析。平均年龄为 57.98±13.85 岁，45.2% 患有严重损伤。具有出色的可靠性（观察者内 ICC _2,1  = 0.90；95% CI：0.84, 0.93；观察者间 ICC _2,1  = 0.89；95% CI：0.83，0.93）。布兰德-奥尔特曼图表现出令人满意的一致性。在同时效度分析中，发现 SATIS-Stroke 和 SS-QOL 之间存在强、正、显着的相关性（r _s = 0.74；p <0.001，r ² =0.44；p=0.001）。诊断准确性令人满意，敏感性为 80.8%，特异性为 85.2%。

结论

巴西版 SATIS-Stroke 问卷表现出足够的可靠性、同时效度和诊断准确性。因此，这是一种有效的、可重复的措施，用于评估中风后活动和参与的满意度。
