Abstract

Background: There is limited research on the Minimal Important Change (MIC) of the Chinese Western Aphasia Battery (WAB). Since an MIC for Chinese WAB has yet to be established, the clinical implications of data using the Chinese WAB remain unclear.

Aim: This study was to establish the MIC of the Aphasia Quotient (AQ) of the Chinese WAB.

Design: The study is a prospective, longitudinal study.

Setting: The rehabilitation department of a Class A tertiary hospital.

Population: One hundred six patients with aphasia after stroke were included and analyzed in the study.

Methods: Patients were evaluated by a speech and language therapist using the Chinese version of WAB before and after the 2 week intervention. Patients and their primary therapist and caregiver provided a global rating of changes in patients' oral communication ability using the 7-point Likert Scale after the speech and language therapy. Three anchor-based methods were used to examine the MIC: the ROC-based method (MICROC), the predictive modeling method (MICpred), and the MICpred-based method adjusted for the proportion of improvement (MICadj).

Results: MICadj was the best parameter in this study. The participant, caregiver, and therapist anchor-based MICadj estimated in the present study was 6.98, 6.73, and 6.00, respectively.

Conclusions: Our data provide the first estimate of MIC value for the Chinese WAB-AQ. Future studies with larger sample sizes are needed to refine the estimated value.

Clinical rehabilitation impact: The current study has advanced the research on the properties of Chinese WAB.

《中西失语词典》失语商数的微小重要变化。
背景:中西方失语量表(WAB)的最小重要变化(MIC)研究有限。由于中国WAB的MIC尚未建立,使用中国WAB的数据的临床意义尚不清楚。目的:建立汉语WAB失语商(AQ)的MIC。设计:本研究为前瞻性、纵向研究。单位:某三级甲等医院康复科。人群:106例脑卒中后失语患者被纳入研究并进行分析。方法:在干预前和干预后2周,由语言治疗师使用中文版的WAB对患者进行评估。在言语和语言治疗后,患者及其主要治疗师和护理人员使用7分李克特量表对患者口头沟通能力的变化进行了全面评分。采用三种基于锚定的方法来检验MIC:基于roc的方法(MICROC)、预测建模方法(MICpred)和基于改善比例调整的基于MICpred的方法(MICadj)。结果:MICadj是本研究的最佳参数。在本研究中,参与者、照顾者和治疗师基于锚定的MICadj分别为6.98、6.73和6.00。结论:我们的数据首次估计了中国WAB-AQ的MIC值。未来需要更大样本量的研究来完善估计值。对临床康复的影响:本研究促进了对中药骨胶凝剂特性的研究。
