There are four procedures to present the implications of a correlation in terms of our ability to use the correlations to make successful predictions:
Validity correlations can be evaluated in the context of a particular area of research or application.
A nomological network refers to the interconnections between a construct and other related construct. There are several methods to evaluate the degree to which measures show convergent and discriminate associations:
The correlations between measures are called validity coefficients. Validity generalization is a process of evaluating a test’s validity coefficients across a large set of studies. Validity generalization studies are intended to evaluate the predictive utility of test’s scores across a range of settings, times and situations. These studies can reveal the general level of predictive validity (1), reveal the degree of variability among the smaller individual studies (2) and it can reveal the source of the variability among studies (3).
| Method used to measure the two constructs | |
Association between two constructs | Different methods | Same method |
Different constructs (not associated) | Heterotrait-heteromethod correlations. This is nonshared trait variance and nonshared method variance and probably the weakest correlation. | Heterotrait-monomethod correlation. This is nonshared trait variance and shared method variance. A moderate correlation is expected. |
Same constructs (associated) | Monotrait-heteromethod correlations. This is shared trait variance and nonshared method variance. A moderate correlation is expected. | Monotrait-monomethod correlation. This is shared trait variance and shared method variance. This is probably the strongest correlation. |
A requirement for convergent and discriminant validity in the multitrait-multimethod matrices could be that the correlations of a construct should be more highly correlated with other measures of this construct than with other constructs using the same method.
