在現今的社會科學研究中，信度與效度的檢定，不僅是正式的研究程序所必須，也已成為研究報告中，必要的一個環節。當然，信度與效度的檢定，種類與方法極為眾多，要注意的是，檢定方法不一定偏於其中一種，研究者不以視需要，在不同的研究工作中，選擇一種適當的方法，或同時採用幾種方法進行，所用的檢定方法愈多，則研究的結果，通常也愈精確。要注意的是，任何科學研究都會注意信度與效度，亦要求研究結論的可信度與有效性，缺乏信度與效度的驗證，研究將遭到質疑，對於研究的科學性步驟，都是有所欠缺的，則其結果的呈顯與推論，都也將是不周密的。

The statistical test of reliability and validity are necessary for research process as well as an inevitable part of research report in modern social science. Surely, The test of reliability and validity are of kinds but alternatively applied for researcher only in suitable situation. It may used one way or multi ways simultaneously of which depends on research target aimed by itself. The more ways researcher of social science initialized the more accurate the research will achieve. Any research steps of social science would be questioned in want of test of reliability and validity and thus no conclusion will be identified as valid and reliable with no exception.
