Abstract
- The Developmental Test of Visual Perception – Third Edition (DTVP-3) is a recently published revision of a visual perceptual test from the United States, frequently used by occupational therapists. It is important that tests have adequate documented reliability and validity and are evaluated in cross-cultural contexts. The purpose of the study was to assess the reliability and validity of the DTVP-3 when completed by a group of Australian participants. Thirty-nine typically developing children 6–8 years of age completed the DTVP-3 and the Developmental Test of Visual-Motor Integration – 6th edition (VMI-6). The internal consistency of the DVTP-3 was assessed using Cronbach alpha coefficients and the DTVP-3's convergent validity was examined by correlating it with the VMI-6 and its two supplementary tests. The five DTVP-3 subscales' Cronbach alpha coefficients ranged from.60 to.80 while its three composite indexes had coefficients all at the.80 level. The VMI-6 was significantly correlated with the DTVP-3 Figure Ground and Visual Closure subscales and the Motor-Reduced Visual Perception Index (MRVPI). The VMI-6 Visual Perception Supplementary Test was significantly correlated with the DTVP-3 Figure Ground, Visual Closure, Form Constancy, MRVPI, and General Visual Perception Index. The DTVP-3 exhibited acceptable levels of internal consistency and moderate levels of convergent validity with the VMI-6 when completed by a group of Australian children. [ABSTRACT FROM AUTHOR]
