Factor analysis for responses to the WAIS-R by 1,630 adults of the Italian standardization sample produced two factor solutions in different age groups, and showed high factorial similarity when compared with the same American solution. An estimate of g factor and variance components showed some difference with American data: a lower proportion of g and common variance, and a greater specificity characterized the Italian version with an almost identical error variance. For both the estimate of… CONTINUE READING
