Summary
A standardized Rorschach scoring training method using the Perceptanalytic system achieved high interscorer reliability. This classroom-based training model proved effective over a six-year period for graduate psychology students.
Area of Science:
- Psychological assessment
- Clinical psychology training
- Psychometrics
Background:
- The Perceptanalytic system offers a standardized Rorschach scoring method.
- Previous studies indicated high interscorer reliability in classroom settings by 1984.
Purpose of the Study:
- To evaluate the long-term effectiveness of the Perceptanalytic system for Rorschach scoring training.
- To assess interscorer agreement with continued use in a graduate clinical psychology program.
Main Methods:
- A six-year follow-up study (1985-1991) collected in vivo data from classroom training.
- 167 graduate clinical psychology students participated in the training.
- Data analyzed coding and summarizing operations for interscorer agreement.
Main Results:
- High interscorer agreement was achieved for both Level I and Level II Rorschach responses.
- Overall agreement reached 90% (SD = 6.0%) across 54,329 operations.
- The Perceptanalytic system demonstrated sustained reliability in training.
Conclusions:
- The Perceptanalytic method provides sufficiently high interscorer reliability for training doctoral students in Rorschach scoring.
- Classroom-based training is effective for achieving reliable Rorschach scoring.
- Further research into Rorschach training systems and the learning process is recommended.
