Rater agreement for the Rey-Osterrieth Complex Figure Test

This report assesses the intrarater and interrater reliability of quantitatively scoring the Rey‐Osterrieth Complex Figure Test (RCF). The intrarater correlation coefficients were .96, .99, and .96, and the interrater correlation coefficients were .88, .97, and .96 for the Copy, Immediate Recall, and Delayed Recall, respectively. However, statistically significant mean differences in score were found between raters on the Copy, Immediate, and Delayed Recall. Though the majority of structural units within the RCF are reliably scored, several units had a greater magnitude of observed scoring differences compared to the other units after adjusting for expected differences. Overall, reliability estimates demonstrate high intrarater reliability and acceptable interrater reliability except for the potential for systematic scoring differences.
