The Boston qualitative scoring system for the Rey-Osterrieth complex figure: Description and interrater reliability

Abstract

This report describes a qualitative scoring method for the Rey-Osterrieth Complex Figure (ROCF) that provides scores for fragmentation, planning, organization, presence and accuracy of various features, placement, size distortions, perseveration, confabulation, rotation, neatness, symmetry, and immediate and delayed retention. Interrater reliability is reported for productions drawn by 60 adolescents and adults. Each production received 16 initial scores based on specific criteria. Six additional summary scores were then calculated using scores from all three conditions (i.e., copy, immediate, and delayed recalls). Kappa statistics and intraclass correlations indicated excellent interrater reliability. In sum, the Boston Qualitative Scoring System for the ROCF appears to be a highly reliable and informative method for scoring this widely used instrument.
