Peebles' Rorschach Content Scoring System: Reliability, Normative Data, and Validity

Abstract

This study reports normative data for the Peebles Rorschach content scoring system. Group Rorschach protocols from undergraduates were scored and reliably classified by quadrant. Frequencies were obtained by sex and by quadrant. Social desirability was demonstrated to vary across quadrants. The validity of quadrant classification was suggested by self-reports and MMPI scales. MMPI profile code predictions were made by experts for each quadrant and compared with obtained mean profile codes. The scoring system was evaluated and theoretical origins were discussed.
