Potential Projective Material on the Rorschach: Comparing Comprehensive System Protocols to Their Modeled R-Optimized...

Area of Science:

• Psychological assessment
• Personality psychology

Background:

• Exner (1989) and Weiner (2003) identified Distortions, Movement, and Embellishments as key Rorschach codes indicating projective content.
• The frequency and distribution of these codes are crucial for interpreting Rorschach protocols.

Purpose of the Study:

• To determine the frequency of Distortions, Movement, and Embellishments codes in normative Rorschach data.
• To assess if these code frequencies vary by response number.
• To evaluate the impact of R-PAS statistical modeling on these projective codes compared to the Comprehensive System (CS).

Main Methods:

• Analysis of two normative Rorschach reference databases.
• Examination of code frequencies across response numbers (1st, 2nd, 3rd, 4th, last).
• Comparison of original CS data with R-PAS modeled data using statistical measures (Cohen's d).

Main Results:

• Approximately 40% of responses contained one type of projective code, 15% contained two, and 1.5% contained all three.
• Code frequencies did not significantly change based on the response number.
• No significant mean differences were found between original CS and R-PAS modeled records (M Cohen's d = -0.04).

Conclusions:

• R-PAS administration and statistical modeling appear to maintain the integrity of projective material in Rorschach protocols.
• Findings suggest that R-PAS optimized administration does not alter the presence or extent of potential projective content.
• This supports the validity of R-PAS in capturing psychologically relevant information from Rorschach responses.
