Rorschach differences in normal and delinquent white male adolescents: A discriminant function analysis

Abstract

Rorschach productions from 38 normal and 30 delinquent White male adolescents were scored by three Ph.D. clinical psychologists according to the method given by Beck. The groups were equated for IQ, social class, and age at the time of testing. Rorschach scales representative of various personality dimensions, i.e.,R, M, F, F+, FC, CF, C, FC: CF + C, Sum C, Affective Ratio, Shading, H, andA, were subjected to a linear discriminant analysis. The results showed highly significant and accurate differentiation between the groups (p<0.0005, correct classification rate =86.8%); however, theAffective Ratio was the only scale that heavily contributed to the discrimination. The difference between the groups on this scale was attributed to the delinquents' passive cognitive style. The results also lend support to the notion that delinquents differ from normals along the dimension of impulsivity, a finding relevant to psychodynamic theories of delinquency as reflective of serious ego deficits. Fuller consideration of Rorschach symbolic content and qualitative features of response is recommended.
