Note. Convergent and discriminant validity correlations were averaged after conversion to Fisher’s z and then re-converted to correlations. Average convergent and discriminant validity correlations were compared using the test of dependent correlations with the nuisance correlation being the average of the inter-correlations between the convergent and discriminant validity measures.
