Abstract
The present study considered a factor analysis of the Rorschach Comprehensive System. That is, exploratory factor analysis was conducted to examine the psychometric structure of the Rorschach Comprehensive System using protocols from two diagnostic categories, some of which were used to construct the standardization population for this instrument. The current study utilized protocols from a total of 714 subjects. These subjects can best be described when stratified into two major categories: nonpatient and inpatient depressive adults. The Rorschach Comprehensive System was administered to each patient by experienced psychometricians according to standard procedures set forth in the manual some of which were used to construct the standardization population (Exner, 1990). Permission to use this data was granted by Rorschach Workshops and John Exner, Jr. Thirty variables which met the basic assumptions were submitted to maximum likelihood (ML) factor analysis. The resulting 4 factors were subjected to oblique rotation procedures for further clarification of the underlying dimensions. Maximum likelihood (ML) factor analysis extracted a four factor model which accounted for 37.5% of the total variance in the nonpatient group and 42.6% for the depressives. Findings from these factor analyses are discussed in semblance to previously established factor analytic findings for the Rorschach Comprehensive System. Current findings are also discussed in relation to the underlying content dimensions represented in the Rorschach Comprehensive System for nonpatient and inpatient depressive adults, development of factor analytically derived subscales, and the implications of this factor model for the interpretation strategies with this instrument.
