Good day,

I am attempting to review several studies that mention the reliability and validity of a Stroop test. I wanted to know what is there a technique that can take the reliability coefficient of different studies and be able to tell me that overall all this type of Stroop test tool is reliable.

Noted, the Stroop test has many different versions, and in the found studies they are all different as well. Their evidence of reliability also differs, like some use test retest, some use cronbach alpha.

So, as a starting base I am wondering where to begin. Can this be done at all? Additionally, can the same process be done for validity?
