Intelligence and non-intelligence factors contributing to scores on the Rorschach Prognostic Rating Scale.
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.
