Intelligence and Non-Intelligence Factors Contributing to Scores on the Rorschach Prognostic Rating Scale

Abstract

The relationship between the Rorschach Prognostic Rating Scale (RPRS) and the Wechsler Adult Intelligence Scale (WAIS) was investigated to identify the factors, intelligence and others, which contribute to the RPRS. Correlation between the RPRS total and WAIS FSIQ showed that approximately 43% of the variance in the RPRS total can be accounted for by the variance in the FSIQ. Verbal IQ is not significantly more highly correlated with the RPRS total than the Performance IQ (p less than .10). Factor analysis of the six RPRS subscores resulted in two factors. Subsequent factor analysis of the six RPRS subscores plus FSIQ and the factor analysis of the six RPRS subscores plus PIQ and VIQ showed the first factor to be an intelligence factor accounting for 85% of the common variance. The RPRS variables FL, FM, M and Sh loaded most heavily on this factor. The second factor was a non-intelligence factor accounting for 15% of the common variance. Small m is clearly the main determinant of this factor, followed by Sh.

The clinical utility of the Rorschach: Unfulfilled promises and an uncertain future.

“…We echo Meyer and Handler’s call for contemporary researchers to investigate the merits of the RPRS, as little research on this scale has been conducted since the early 1980s. However, it will be important for such research to address both Shield’s (1978) concern about the scale’s sensitivity and the potential confound stemming from the strong association between the RPRS and intelligence ( r = .66; Hathaway, 1982).…”

The Rorschach Ego Impairment Index: Prediction of Treatment Outcome in a Child Psychiatric Population

“…The strength of these Rorschach variables is that they may provide a measure of the integrity of personality structure and coping resources apart from symptoms or diagnostic status. Hunsley and Bailey (1999) expressed concerns about the methodological limitations of some of the studies that were included and the strong association between the RPRS and intelligence (r = .66; Hathaway, 1982). The RPRS was described by Klopfer, Ainsworth, Klopfer, and Holt (1954) as a measure of ego strength, which reflected "reality testing, emotional integration, self-realization, and mastery of reality situations" (p. 688).…”
