Explanation: Predictive validity shows the extent to which a score on a scale predicts scores on some criterion measure. For example, the validity of a cognitive test for job performance is the correlation between test scores and the performance rating of the supervisor.There are four types of validity, they are face, construct, content, and predictive validity inclusive.
The predictive validity can be explained or established in such a way that a tests are administered to a something and later seeing if the tests are correlated or went along with the future performance of that thing. This simply means that , how likely it is for a test score to predict the future performance.
In this case, the new assessment can be concluded of having a good predictive validity when it can successful differentiates those who will later be depressed from those that will not.
