Evaluation of convergent and discriminant validity with multitrait-multimethod correlations.

A procedure for evaluation of convergent and discriminant validity coefficients is outlined. The method yields interval estimates of these coefficients in a construct validation study conducted via the multitrait-multimethod approach, as well as permitting examination of their population relationships. The procedure is readily employed in behavioural research using the increasingly popular latent variable modelling methodology. The method is illustrated with a numerical example.
