CHIODI, Marcelo Gulini  and  WECHSLER, Solange Muglia. Convergent Validity Study of the Cognitive Abilities Battery Woodcock-Johnson III - Extended Version. Aval. psicol. [online]. 2012, vol.11, n.1, pp. 63-75. ISSN 1677-0471.

The purpose of this study was to evaluate the convergent validity of the Cognitive Abilities Battery Woodcock-Johnson III (WJ-III) Expanded version by comparing it to the WJ-III Battery Standard version. The sample consisted of 70 public elementary and high school students. The results obtained were analyzed using Pearson’s correlation and the Analysis of variance between sex and age. Correlations were found between both the total scores of the WJ-III Expanded and the total scores of the WJ-III Standard, as well as between the subtests that assess Crystallized Intelligence of the WJ-III Expanded vs. the WJ-III Standard. Significant correlations were also found by comparing the subtests used to assess other skills of both versions of the WJ-III battery. There were significant differences regarding the age variable in both the Expanded and the Standard. Those data show that the WJ-III Battery Extended version features a convergent validity with the WJ-III Standard version, which may expand the possibilities of those instruments for intellectual evaluation.
