Prediction of differences in Rorschach protocols from the Personality Assessment System

The Personality Assessment System (PAS) is derived from certain subtest scores on any Wechsler test by rather simple calculations. It purports to measure, among other personality attributes, developmental changes in the Internalized-Externalized (I-E) dimension of personality, which is akin to the Introversion-Extroversion construct reflected by some Rorschach measures. PAS scores from a tightly defined sample of normal adults were contrasted with Experience Balance (EB) and Body-image (B) scores derived from Rorschach protocols by "blind" scorers. Significant relations were found between EB ratios produced via the Exner and Klopfer scoring systems and the primitive (early childhood) I-E scores from the PAS. The B scores produced by the Body Image scoring system were related to the basic (adolescent) I-E PAS scores. Although significant, the PAS-Rorschach correlations were relatively poor, in part because it was difficult to define the center of the internalization-externalization continuum in terms of the Rorschach protocols. It is, nevertheless, provocative that traditional scorings of the Rorschach responses of adults assess differences not only in this personality trait, but also in its development, as determined from scaled scores on Wechsler subtests.     

Psychosomatic diseases and the Rorschach test

Despite numerous efforts to identify a Rorschach profile uniquely associated with and helpful in diagnosing psychosomatic conditions, none has been demonstrated to exist. Although certain Rorschach characteristics have been consistently observed in studies of patients with psychosomatic diseases and can shed light on personality features of these individuals, similar characteristics are encountered in a variety of other conditions as well. This state of affairs is attributable not to short-comings in the Rorschach test, but rather to inadequate conceptualization and categorization of psychosomatic disease.     

Prediction of adolescent and adult delinquency from childhood Rorschach ratings

Relatively few studies have predicted adolescent or adult delinquency from childhood Rorschach data. Incremental validity of Rorschach measures over other known consistent and more easily obtained predictors has typically not been investigated. We addressed Rorschach data's incremental validity over mother's reports of externalizing behavior and mother-child relations for predicting officially registered adolescent and adult delinquency in a longitudinal study of 122 Swedish men. The Rorschach measures we used were aggregates of blind, prospectively performed, global expert ratings based on a holistic evaluation of protocols. An aggregate of Rorschach-based ratings of ego strength significantly improved the prediction of delinquency in adolescence and adulthood over and above earlier identified best predictors (mother's ratings of mother-child relations and externalizing problem behavior).     

The role of perceptual laws in the Rorschach test

The purpose of this study is twofold: to ascertain the perceptual deficits in schizophrenic subjects and to test the assumption that the Rorschach is mainly a perceptual task. Forty-eight subjects participated in the study, distributed in six groups of eight subjects each: normals, affective disorders, and four groups of schizophrenics (chronic paranoid, chronic nonparanoid, acute paranoid, and acute nonparanoid). They were given a perceptual test developed by Fernández-Trespalacios, Bermudez, and Luna (1979). Contrary to previous findings, no differences in the perceptual test were found among the groups. In the second part of the study, a group of schizophrenic subjects was given the Rorschach and the perceptual test in a balanced order. Subsequently, subjects in the experimental group were trained in the perceptual laws they had failed. Comparison of the Rorschach protocols obtained before and after this training failed to show any significant differences in the expected direction, thus questioning the perceptual nature of this test. Interestingly, an increase in negative categories of the Rorschach subsequent to the perceptual training was observed.
