Rey-Osterrieth complex figure normative data for the psychiatric population.

Area of Science:

• Neuropsychology
• Psychiatry
• Clinical Psychology

Background:

• Accurate normative data are essential for neuropsychological assessment.
• Existing norms often do not represent psychiatric populations, potentially leading to misinterpretation.
• The Rey-Osterrieth Complex Figure Test (RCFT) is a widely used measure of visuospatial constructional ability and memory.

Purpose of the Study:

• To establish normative data for the RCFT specifically from a psychiatric inpatient population.
• To develop calculation tools to aid in the interpretation of RCFT scores within this population.
• To highlight the importance of using appropriate norms for individuals with psychiatric conditions.

Main Methods:

• Collected RCFT and Test of Memory Malingering (TOMM) data from 301 psychiatric inpatients (1999-2018).
• Utilized multiple regression analysis with age and education as predictors for RCFT subscores (Copy, Short-Delay Free Recall, Long-Delay Free Recall, Total Recognition, Percent Retained).
• Calculated base rates for Total Recognition subscores and developed a score calculator using spreadsheet software.

Main Results:

• Age and education were significant predictors for most RCFT scores.
• Regression equations and standard errors were used to create a user-friendly score calculator.
• Norms derived from healthy adults underestimated performance in the psychiatric inpatient sample, confirming the need for specific data.

Conclusions:

• The presented RCFT normative data are derived from a substantial cohort of psychiatric inpatients.
• The developed data and calculation tools are valuable for clinical practice and research involving individuals with serious mental illness.
• These normative data enhance the precision and validity of neuropsychological assessments in psychiatric populations.
