Correcting for gender on the Cognistat Judgment subtest.

The Cognistat is a widely used screening instrument for the assessment of higher cerebral functioning. This study investigated the effects of gender and age on a specific item from the metric sequence of the Cognistat Judgment subtest. Participants consisted of 110 cognitively intact volunteers (45 males, 65 females). Results showed that females responded with 1-point answers, as defined by the manual, significantly more often than those who responded with a manual-defined 2-point response. Males responded with a 2-point answer with a significantly greater frequency than they responded with 1-point responses. The data indicate that a gender correction for females should be made to the Judgment subtest of the Cognistat.
