Q&A
Q1:the standard error of measurement of the total score was calculated for both the test-retest and the interrater conditions to determine the consistency of scoring in absoloute terms and to evaluate the minimal detectable change.
Ans:DGI再測信度和施測者間條件檢驗總分的標準誤(SE of measurement, SEM)以判斷分數在絕對數值中的一致性，及評估最少偵測變化(Minimal Detectable Change)。

Q2:the Bland and Altman method of plotting the difference of scores against total scores of each participant of the 2 testing times //showed good realibility.

Q3:the mean differences in interrater scoring are plotted against the mean scores of the 2 raters for the same participant in figure 1B.
Ans: Q2 & Q3 are the same meaning of telling us the ICC scores of the interrater and test-retest have increased when we look in the Bland and & Alman plot and Table 2.e.g item 5:icc scores 0.56(test-retest )< icc scores 0.83 (interrater)
against difference(Y axis) vs mean (X axis)

Q4:for item 5,and for item 7 ,the realibility for the test-retest conditionwas lower than that of the interrater condition.
Ans:That is means the realibility

Q5:on item 8,there was total agreement in both test-retest and the interrater condition indicating that instructions for item 8 were specific enough to leave little doubt about scoring.
Ans:total agreement = 完全一致

Q6:the criterion for statistical significance was P less than .05.
Ans:
P值是論文中最常用的一個統計學指標，可是其誤用、解釋錯誤的現象卻很常見。因此，很有必要說明p值的意義、用法及常見錯誤。
釐清自己的觀念:
1.角色--
2.貢獻--對病患的成效有多少,能排除其他介入的因素來確定OTR 在臨床給予的治療?
