The factor structure of the Frostig Developmental Test of Visual Perception

Comparison of factor structures for the Frostig Developmental Test of Visual Perception

The purpose was comparison of the factor structure of the Frostig DTVP based on current research reporting intercorrelations of scores on the 5 Frostig subtests. Ss in the 11 studies examined were children from preschool through the second grade. The intercorrelation matrices from the studies were analyzed using a principal components analysis with orthogonal rotation as a common factor analytic procedure. Results indicated a single-factor structure described the 5 Frostig subtests in 9 of the 11 studies examined with that single factor accounting for 50 to 60% of the total variation. It is possible that one or more additional specific factors may exist but the analyses in this study did not identify more than the single factor.
