怡靜的新春賀禮

"A comparison of the responsiveness of the long-form and simplified Stroke Rehabilitation Assessment of Movement: Group and individual level analysis"

稿件被 Physical Therapy 期刊接受了。。。這是怡靜第一篇英文論文

拖了一段時間，剛好碰到農曆年前被接受

相關研究方法雖然我們團隊已執行了幾次

但審查者還是能提出一些關鍵問題。。。

怡靜特別值得稱讚/祝賀的地方：她已有獨立解決(回覆)關鍵問題的能力。

如【個別反應性分析方法與假設】之說明，幾乎都是她獨立完成的！簡述如下：

Deduction of SE_difference formula

          In classical test theory, the observed scores comprise true scores and measurement errors. If a patient’s ability (i.e., true score) has not changed between assessments, which is a necessary assumption in the estimation of reliability, the fluctuation of observed scores between two assessments obtained on the same measure by the same individual patient comes solely from the measurement errors (formulae 1 and 2). Therefore, the variance of the observed change scores (measurement error between repeated assessments) is equal to the variance of the difference of the measurement errors (formula 3). In addition, the measurement errors are random variables and are assumed to be independent between repeated assessments. Thus, the covariance of the measurement errors between admission and discharge should be zero and could be ignored for calculation of SE_difference (formula 4). The deduction of SE_difference formula are presented as follows:

Note. The SE means measurement error, not standard error of the mean. The SE represents the measurement error of an individual patient’s Rasch score, and the SE_difference means the measurement error of an individual patient’s Rasch change score between repeated assessments.
