On the synthesis of information from psychological tests.

Résumé

This paper evaluated research concerning the synthesis or integration of information from Wechsler intelligence, Rorschach, and Thematic Apperception tests, Minnesota Multiphasic Personality Inventory, and Millon Clinical Multiaxial Inventory in the process of personality assessment. Five methodological issues were considered in evaluating the extent to which the results contributed to the statistical prediction of clinical status: the method of measuring the clinical criteria, the status of participants or the groups tested, whether results were estimated for specific diagnostic groups, whether there were estimates of incremental validity for different psychological tests, and if diagnostic group status was predicted on the basis of test scores as opposed to the report of differences on tests between diagnostic groups. Few studies met as many as four of these methodological criteria; several provided information relevant to the process of statistical prediction.
