We can now define positive and negative predictive value as follows: Positive predictive value = a / (a+b). Negative predictive value = d / (c+d). Post-test probability of disease given a positive test = a / (a+b). Post-test probability of disease given a negative test = c / (c+d). Notice that we are now using the rows instead of columns, as for sensitivity and specificity.
Definition of Predictive Validity: In the context of pre-employment testing, predictive validity refers to how likely it is for test scores to predict future job performance. Predictive validity is one type of criterion validity, which is a way to validate a testâs correlation with concrete outcomes. The best way to directly establish predictive validity is to perform a long-term validity study by administering employment tests to job applicants and then seeing if those test scores are correlated with the future job performance of the hired employees.
