Types include Content Validity (extent to which a tool measures all aspects of the domain it is supposed to), Construct Validity (when results coincide with what a theory about some construct would predict.

Number that quantifies the size of relationship between two variables, noted by the symbol r, rating from -1.0 to 1.0
Sensitivity
Probability that a person with a mental disorder is diagnosed as having a disorder. True Positive
Specificity
