生態效度

Ecological validity refers to the degree to which test performance corresponds to real-world performance.

中文解釋：生態效度為分析受測者之評估表現與真實環境下表現之相關性。

判斷標準：欲驗證之評估工具與ADL或outcome measure評估工具之相關性。
                    ≧ 0.60 excellent；
                    0.31-0.59 adequate；
                    ≦ 0.30 poor

臨床意義：評量所得所得結果可推論至真實情境之程度，即結果是否可作為推估受測者真實生活能力高低依據之指標。

研究設計：同時測量欲驗證之評估工具及ADL或outcome measure評估工具，看工具間的相關程度。
