Assessment and development of organizational ability: The Rey Complex Figure Organizational Strategy Score (RCF-OSS)

The Rey Complex Figure Organizational Strategy Score (RCF-OSS) was devised for pediatric populations to cater for developmental variability. A sample consisting of 376 children aged between 7.0 and 13.11 years was recruited for the standardization of RCF-OSS. The interrater reliability (.85 to .92) and temporal stability (.79 to .94) of the RCF-OSS are acceptable. RCF-OSS correlated moderately with RCF accuracy memory and organization, however it seems to be measuring an independent aspect of performance, possibly strategy. Moderate Linear relationships were observed with executive function and memory measures. Considerable age-related variation in strategy formation was observed with significant maturity occurring between the ages of 7 years and 11 years. Surprisingly, older children used fragmented strategies more than the younger age groups. In conclusion, the RCF-OSS is a useful adjunct to traditional accuracy scoring procedures, and the normative data indicates that organizational skills may not consolidate until middle to late adolescence.
