A Multitrait Multimethod Measurement Approach to the Traits (or States) of Anxiety,Depression and Hostility

This study tested the convergent and discriminant validities of various psychological techniques used for the measurement of the affects of anxiety, depression and hostility. The subjects were 29 psychiatric patients and 25 normal controls, all males. Subjects were interviewed and rated for the three affects and given an extensive battery of tests. Anxiety and depression measures from ratings, checklists, and questionnaires demonstrated good convergent validity but poor discriminant validity. The projective methods did not demonstrate much convergent validity. Hostility was separable from anxiety and depression but the tests showed poor convergent validity for hostility. In the normals, fantasy hostility (TAT) and admitted hostility (Multiple Affect Adjective Check List) showed some convergence, but in the patients there was no congruence between these two levels.
