The effect of administration skills on Rorschach protocols

Area of Science:

• Psychological Assessment
• Clinical Psychology
• Psychometrics

Background:

• The Rorschach is a widely used personality assessment tool.
• Empirical data on the expertise required for valid Rorschach protocol collection is lacking.
• Understanding training effects on Rorschach administration is crucial for reliable assessment.

Purpose of the Study:

• To investigate the impact of training on Rorschach administration proficiency.
• To identify errors associated with different training levels.
• To determine the expertise level ensuring effective Rorschach administration.

Main Methods:

• A within-subject design was used, analyzing Rorschach protocols from 50 psychologists at three training stages (T1, T2, T3).
• Protocols were evaluated for errors in the Response and Inquiry phases.
• The study tracked changes in administration proficiency throughout a Rorschach training course.

Main Results:

• Initial training (T1) showed more errors and simplistic protocols in the Response phase.
• Proficiency improved by T2, with fewer omission errors but increased commission errors in the Inquiry phase.
• Effective Rorschach administration was achieved by T3, indicating mastery.

Conclusions:

• A 100-hour training course with 10 supervised administrations and feedback is suggested for Rorschach proficiency.
• Training significantly enhances the quality of Rorschach protocol collection.
• Adequate training is essential for ensuring the validity of Rorschach assessments.
