title: Cross validation of the Lu and colleagues (2003) Rey-Osterrieth Complex Figure Test effort equation in a large known-group sample.
abstract: A Rey-Osterrieth Complex Figure Test (ROCFT) equation incorporating copy and recognition was found to be useful in detecting negative response bias in neuropsychological assessments (ROCFT Effort Equation; Lu, P. H., Boone, K. B., Cozolino, L., & Mitchell, C. (2003). Effectiveness of the Rey-Osterrieth Complex Figure Test and the Meyers and Meyers recognition trial in the detection of suspect effort. Clinical Neuropsychologist, 17, 426-440). In the current cross validation of this validity, the credible patient group (n = 146; 124 with equation data) outperformed the noncredible group (n = 157; 115 with equation data) on copy, 3-min recall, total recognition correct and the Effort Equation, but the latter was most effective in classifying subjects. A cut-off of ≤50 maintained specificity of 90% and achieved sensitivity of 80%. Results of the current cross validation provide corroboration that the ROCFT Effort Equation is an effective measure of neurocognitive response bias.
