Test-retest reliability of colored filter testing.
This article evaluates the reliability of colored filter testing procedures. Properly chosen colored filters, with the tint being specific to each patient, are said to be effective in the treatment of dyslexia. We investigated the test-retest reliability of colored filter testing in relationship to two specific symptom levels using a forced-choice test procedure. This research was to evaluate test-retest reliability, not the validity of colored filter testing. Forty-one participants (28 boys and 13 girls) ranging in age from 15 to 17 years served as participants. Two tests, separated by 2 weeks, were conducted under standard conditions. Results indicated poor test-retest reliability.
