A Wherry (1984) hierarchical factor solution was obtained on the WAIS‐R subtest intercorrelations for 108 alcoholic adults. An ability arrangement consistent with Vernon's (1950) structure‐of‐intellect paradigm was found. This ability hierarchy consisted of a strong general intelligence ( g ) factor defined by all 11 subtests, which accounted for 49% of the variance. The primary level of the ability hierarchy consisted of spatial‐perceptual‐ mechanical ( k:m ), Freedom from Distractibility (FD), and Verbal Comprehension (VC) factors. Those respective factors accounted for 86%, 4%, and 3% of the total subtest variance.
