Comparison of scores on two recent editions of the developmental test of visual-motor integration

Standard scores on the third and fourth editions of the Developmental Test of Visual-motor Integration (VMI-3 and VMI-4) were compared for a sample of 120 children (4 to 17 years of age) referred to an outpatient diagnostic clinic for developmental, learning, attention, mood, and behavior problems. The two editions of the test have the same items, so the test was administered only once to each child, but the editions differ in their scoring systems and norms. The correlation between the pairs of standard scores on the two editions was .99, and the absolute mean difference between scores was only 1.5 points.
