Comparability of the Rey and Mack forms of the Complex Figure Test

Equivalent versions of the Complex Figure Test (CFT) are useful for assessi ng change over time in constructional skills, planning, spatial organizatio n, 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 Mac k CFTs obtained from 245 adults involved in a study of the neuropsychologic al correlates of sleep apnea and its treatment. Accuracy scores did not sig nificantly differ between individuals with and without sleep apnea. Also, t here was no significant difference between copy or recall accuracy scores o btained on the Rey and Mack CFTs. Similar correlations were found between r elevant demographic factors, estimated IQ, and accuracy scores for both CFT s. These data suggest that the Mack figure may be a useful alternative to t he Rey CFT.
