Comparability Of The Rey And Mack Forms Of The Complex Figure Test

Equivalent versions of the Complex Figure Test (CFT) are useful for assessing change over time in constructional skills, planning, spatial organization, and visual-spatial memory while minimizing practice effects. To address the need for an equivalent version of the CFT to the Rey, the present study compared copy and 45 min-delayed recall accuracy scores of the Rey and Mack CFTs obtained from 245 adults involved in a study of the neuropsychological correlates of sleep apnea and its treatment. Accuracy scores did not significantly differ between individuals with and without sleep apnea. Also, there was no significant difference between copy or recall accuracy scores obtained on the Rey and Mack CFTs. Similar correlations were found between relevant demographic factors, estimated IQ, and accuracy scores for both CFTs. These data suggest that the Mack figure may be a useful alternative to the Rey CFT.
