VMI and VMIp test-retest comparisons indicated no significant bias (subjects did not tend to score better on retest). Interrater correlations were strong (0.75 to 0.88). One of the two trained scorers tended to provide higher scores than the other (mean difference in standardized scores = 1.54). Trained scorers had no significant scoring bias compared with the experienced scorer. Analyses included interrater and test-retest assessments of bias, 95% limits of agreement, and intraclass correlation analysis. Scorers strictly applied objective scoring criteria. ![]() All VMI tests were scored by two trained scorers, and a subset of 50 tests was also scored by an experienced scorer. The VMI and VMIp were administered twice, on separate days. Subjects were 163 Native American third- to eighth-grade students with no significant refractive error (astigmatism <1.00 D, myopia <0.75 D, hyperopia <2.50 D, anisometropia <1.50 D) or ocular abnormalities. To assess interrater and test-retest reliability of the 6th Edition Beery-Buktenica Developmental Test of Visual-Motor Integration (VMI) and test-retest reliability of the VMI Visual Perception Supplemental Test (VMIp) in school-age children. ![]()
