TRAUT: a Rorschach index for screening thought disorder. Tripartite Classification of Autisms

Area of Science:

• Psychological assessment
• Psychopathology research
• Cognitive science

Background:

• The Rorschach test is a projective psychological test.
• Identifying thought disorder is crucial for diagnosing and treating psychiatric conditions.
• Existing methods for classifying Rorschach perceptions indicative of thought disorder have limitations.

Purpose of the Study:

• To introduce TRAUT (Thought-Related Absurdity Understanding Test), a new approach for recognizing and classifying Rorschach perceptions linked to thought disorder.
• To establish the validity and utility of TRAUT in differentiating thought-disordered individuals.

Main Methods:

• TRAUT categorizes Rorschach "absurdities" into three types: HYPO (ignoring the blot), HYPER (circumventing the task), and RELER (rationalizing counterfactual images).
• Development of logically derived definitions for clarity, generalizability, and teachability.
• Administration of norms and significance tests to compare TRAUT scores across patient groups.

Main Results:

• Thought-disordered patients exhibited significantly higher TRAUT scores compared to non-thought-disordered patients and normal individuals.
• TRAUT categories demonstrated efficacy in differentiating between various subtypes of thought-disordered patients.
• The TRAUT approach offers a clear, generalizable, and teachable framework for analyzing Rorschach perceptions.

Conclusions:

• TRAUT provides a reliable and valid method for identifying and classifying thought disorder on the Rorschach.
• The system's logical structure enhances its clinical and research applicability.
• TRAUT contributes a valuable tool for the nuanced assessment of cognitive disturbances in psychiatric populations.
