Cr. Reynolds et Ed. Bigler, FACTOR STRUCTURE, FACTOR INDEXES, AND OTHER USEFUL STATISTICS FOR INTERPRETATION OF THE TEST OF MEMORY AND LEARNING (TOMAL), Archives of clinical neuropsychology, 11(1), 1996, pp. 29-43
Using the method of principal factors with varimax and promax rotation
s, the 14 subtests of the TOMAL were subjected to a factor analysis us
ing correlation matrices derived from the standardization sample. A 4-
factor solution was chosen as the overall best solution when mathemati
cal and neuropsychological variables were considered jointly. These fa
ctors (Complex Memory, Sequential Memory, Backwards Memory and Spatial
Memory) were used to develop unit-weighted factor indexes based on re
sponses of the original standardization sample. Normative tables, reli
ability data, and factor structures are reported for clinical use.
