Title:
Validating and improving the test reliability of the motor and balance subscales in the Fugl-Meyer assessment scale for patients with stroke
Background and purpose:
The motor (upper extremity and lower extremity) and balance subscales of the Fugl-Meyer assessment scale (FM and FMB) are commonly used to evaluate motor and balance function in patients with stroke. These scales have shown sufficient reliability, validity and responsiveness in patients with stroke. The original 50-item FM has been analyzed using multidimentional Rasch analysis and formed a calibrated item bank (37 items) for evaluating motor function in patients with stroke. However, whether the FMB constitues a single contruct for evaluating balance function has not been justified. In addtion, it is not clear whether the combination of the 37-item FM and the calibrated FMB improves the test reliability of these scales. The purpose of this study was to investigate the construct validity of the FMB using unidimentinal Rasch analysis. Moreover, we used multidimentional Rasch analysis to improve the test reliability of the 37-item FM and the calibrated FMB.
多向度 Rasch分析的結果也會增加 UE/LE 之信度，若您同意，因為 UE/LE 很常被使用，那研究主題如何訂定！？可更凸顯價值/impact！？
回覆刪除Have revised, thanks!
回覆刪除Thanks!
回覆刪除但前言主要的論述有一些問題：
1. balance subscale 很少被使用。
2. 如果這些 subscales 都有sufficient reliability, validity and responsiveness in patients with stroke，那還有需要進行這個研究？？
3. 37 items 是 short form? it's not. 請留意看原論文。
4. 以 Rasch 分析 unidimensionality 比 CFA 嚴苛許多，並非好方法。
或許可考慮分析其它「較單純」的資料，如 PASS 或 BBS。
回覆刪除比較容易入門。
1. 謝謝老師的修正!short form已改為item bank。
回覆刪除2. 謝謝老師提供研究的主題~我會再找時間跟老師討論!
