ANALYSIS OF VISION TESTER RELIABILITY

Test retest assessment of visual abilities recovered from the Mark II vision tester on two independent samples were submitted to reliability analysis. Subjects were age stratified individuals sampled from Indiana and New York states. Factor analysis of the two data sets revealed five factors underlying the eleven visual abilities. These factors were submitted to reliability analysis along with various weighted sums of responses to the Mark II vision tester Prom. Generally higher reliabilities were observed for these new criteria of visual abilities than previously derived for the standard scoring procedures. The reliability coefficients for the new criteria ranged from 0.45 to 0.78 in the Indiana data set and 0.07 to 0.60 in the New York set.
