Comparison of a modified (two-item) Frisby with the standard Frisby and Random-Dot E stereotests when used with preschool children.
The purpose of this study was to assess the clinical value of the standard Frisby stereotest with young children, and the effects of modifying the standard Frisby to a two-item, forced-choice format. A description of the modified test is presented along with data that indicate the standard Frisby and Random-Dot E (RDE) stereotests are appropriate for children as young as age 30 months; both instruments yield similar results; and the modified two-item Frisby extends the applicability of the test to even younger and/or less communicative children.
