OBJECTIVE: Large studies, with limited
resources call for cost-effective cognitive assessment
methods. Computerized tests offer viable alternatives but
more data is needed on their functioning. Our aim was to evaluate the
overlap between a computerized neuropsychological test battery and a
traditional test of general intelligence (IQ).

METHOD:
Cognitive functioning was assessed in birth cohort mothers (n=80) with two
widely used methods: Cogstate, computerized test battery, and WAIS-IV, a
traditional IQ test. Correlational analyses were conducted.

RESULTS:
We found weak to moderate correlations between the measures, except for
verbal comprehension. The indices of overall performance showed more consistent
correlations than subtests.

DISCUSSION: The overall correlations were in accordance with
earlier studies. Cogstate is relatively independent of verbal comprehension
abilities. The choice of the cognitive assessment method should be strongly
guided by the research question. More studies are needed to evaluate the
applicability of the Cogstate Composite Score in cognitive screening.
