A Comparison of Two Vision Screening Batteries for Clinical and Classroom Use.
Mangrum, Charles T.
The degree of correlation existing between visual screening results obtained from the Keystone Visual Survey Telebinocular and the Titmus Biopter Vision Test was discussed. A sample of 59 children admitted to the University of Miami Reading Clinic during the 1969 summer session was used. They ranged in age from 7 to 16. All subjects were previously diagnosed as having reading difficulty. A trained examiner administered both tests to all subjects, rotating the order with each student. All subjects were screened with both instruments on the same day, and pass or fail for each student was determined using the criteria suggested by respective publishers. After obtaining point biserial correlation coefficients for the 12 paired subtests from the Keystone and Titmus tests, it was found that the correlation coefficients were too low to permit substitution of the Titmus for the Keystone instrument in either classroom or reading clinic. Other inexpensive vision screen instruments should be similarly compared with a suitable criterion to determine the feasibility of substituting one of these for the more expensive Keystone. References are included. (CL)
