Abstract

The Rey-Osterrieth Complex Figure Test (RCFT) is a widely-used measure of visuospatial construction and nonverbal memory. One of the critical aspects of this test is that organizing the figure into meaningful perceptual units during copy enhances its subsequent free recall from memory. This study examined the psychometric properties of a new system for quantifying the organizational approach to the RCFT figure and compared it to another compatible scoring system. We investigated interrater reliability of both systems and explored the influences of copy organization and copy accuracy on immediate recall. Seventy-one participants meeting DSM-IV criteria for obsessive-compulsive disorder and 55 healthy control participants completed the copy and immediate free recall condition of the RCFT. Interrater reliability was evaluated by Kappa coefficients and Pearson correlations. The effects of copy organization and copy accuracy on immediate recall were evaluated using multiple regression analyses. Results indicated that the organizational approach could be assessed with high reliability using both scoring systems. Organization during copy was a strong predictor for subsequent free recall from memory using both approaches. Multiple regression analysis indicated that all organizational elements were not equally predictive of memory performance. This new system represents a very simple and reliable approach to scoring organization on the RCFT, since it requires the identification of only 5 figure components. These characteristics should contribute to its clinical utility.
