Prediction of differences in Rorschach protocols from the Personality Assessment System

Area of Science:

• Psychology
• Personality Assessment
• Psychometrics

Background:

• The Personality Assessment System (PAS) offers a method to assess personality attributes, including developmental changes in the Internalized-Externalized (I-E) dimension.
• This I-E dimension is conceptually similar to the Introversion-Extroversion construct often explored through Rorschach assessments.

Purpose of the Study:

• To investigate the relationship between the Personality Assessment System (PAS) and Rorschach measures.
• To examine if PAS scores, derived from Wechsler tests, correlate with Rorschach-based assessments of personality, specifically Experience Balance (EB) and Body-image (B) scores.

Main Methods:

• PAS scores were calculated from Wechsler test subtest scores.
• Rorschach protocols from a sample of normal adults were scored by "blind" scorers using the Exner and Klopfer systems for Experience Balance (EB) and the Body Image scoring system for Body-image (B).
• PAS scores were statistically contrasted with the derived Rorschach EB and B scores.

Main Results:

• Significant correlations were observed between Rorschach Experience Balance (EB) ratios and the primitive (early childhood) Internalized-Externalized (I-E) PAS scores.
• Body-image (B) scores from the Rorschach were found to be related to the basic (adolescent) I-E PAS scores.
• While statistically significant, the correlations between PAS and Rorschach measures were generally modest, suggesting challenges in precisely aligning the internalization-externalization continuum with Rorschach interpretations.

Conclusions:

• The study demonstrates a provocative link between traditional Rorschach scoring and personality development as measured by the PAS derived from Wechsler tests.
• Despite limitations in correlation strength, Rorschach measures appear to capture aspects of the Internalized-Externalized personality dimension and its developmental trajectory.
• Further research is warranted to refine the conceptual and interpretive links between these psychometric tools.
