A further note on the construct validity of the multidimensional aptitude battery

Abstract

A hierarchical factor analysis was performed on MAB subtest intercorrelations for a sample of 300 male felons to provide a further test of the construct validity of that test. The ability hierarchy thus obtained showed a high degree of congruence with the results of the Wallbrown, Carmin, and Barnett (1988) findings for male felons and the Lee and Wallbrown (in press) for Jackson's (1984) sample. That is, a general (g) factor was loaded positively by all 10 subtests and accounted for 45% of the total subtest variance. A verbal-educational (v:ed) factor was defined by the five verbal subtests and accounted for 21% of their variance. Similarly, a spatial-perceptual (k) factor was defined by performance subtests and accounted for 15% of their variance.
