Rorschachs of 155 schizophrenics, 102 depressives, and 186 nonpatients were collected and scored using the Comprehensive System. Twenty-seven Rorschach variables considered central to interpretation were selected for study. Factor analyses and partial correlations controlling for number of responses, R, were generated in order to investigate the personality organization of each of the three groups. A three factor solution was found to be optimal for each group. Patterns of personality organization were discussed within the three groups and factor structures were compared and contrasted. While similarities occur between the three groups, each group also manifests a unique personality organization. These findings support the hypothesis that schizophrenics and depressives differ from nonpatients in kind, rather than degree of disorder.
