The stroop strategy test: investigation of a computerised version of the Stroop test for classifying Swedish military servicemen.

A computerised test termed the Stroop Strategy Test, utilising the Stroop effect, is described. To assess the test's usefulness and discriminant power, it was given to three military groups adjudged on the basis of interview and a test of intelligence to differ in their qualifications (61 men of Level 1, 41 of Level 2, and 17 of Level 3, in descending order) and a group of 16 men imprisoned or put in detention school for violent behaviour. In a discriminant analysis in which the eight measures the test provided were included and the four groups were compared yielded a discriminant power of 52.6% for the group as a whole, highest (56%) for the military Level 1 group. The potential usefulness of the test is discussed.
