Convergent validity of rorschach and TAT scales of object relations

The Rorschach Mutuality of Autonomy Scale (MOA; Urist, 1977) and the Social Cognition and Object Relations Scale (SCORS; Westen, 1995) have been shown to be reliable and valid measures of interpersonal functioning. Utilizing a sample of 57 outpatients with a Diagnostic and Statistical Manual of Ment al Disorders (4th ed.; American Psychiatric Association, 1994) Axis H diagn osis, this study extends the findings of previous research demonstrating th e reliability and convergent validity of each measure. Analyses focused on the convergent validity between the Rorschach MOA Scale and 8 SCORS variabl es (complexity, affect, emotional investment in relationships, emotional in vestment in values and morals, understanding of social causality, managemen t of impulses/aggression, self-esteem, identity/coherence of self) ratings of Thematic Apperception Test (Murray, 1943) narratives. The conceptual nat ure and clinical utility of these findings are discussed in relation to psy chological assessment.
