Examining the Convergent Validity of the Test of Visual Perceptual Skills – Fourth Edition (TVPS-4) in the Australian Context

Abstract

ABSTRACT The Test of Visual Perceptual Skills – Fourth Edition (TVPS-4) is a recently revised assessment of motor-free perceptual abilities, that was standardized in the United States. The TVPS-4 is commonly used by pediatric occupational therapists, health professionals and educators, therefore it is important that its psychometric properties and use in cross-cultural contexts are investigated. The study aim was to examine the convergent validity of the TVPS-4 when completed by Australian children. Thirty typically developing children aged 6–12 years (17 females and 13 males; mean age 8.7 years; SD = 1.7) completed the TVPS-4, the Developmental Test of Visual Perception – Third Edition (DTVP-3) and the Motor-Free Perception Test – Fourth Edition (MVPT-4). Spearman Rho correlation analyses with bootstrapping were completed to examine the associations between the TVPS-4, DTVP-3 and MVPT-4. The TVPS-4 total scale raw score exhibited strong significant correlations with the DTVP-3 (rho = .745, p < .000) and MVPT-4 (rho = .791, p < .000) total scale raw scores, and moderate to strong significant correlations with all of the DTVP-3 subscales (rho = .540 to .717, p = .002 to .000) and three of the MVPT-4 subscales (rho = .536 to .695, p = .004 to .000). Several weak to moderate significant correlations were found between the TVPS-4 and DTVP-3 subscale raw scores (rho = .370 to .607, p = .044 to .001). The TVPS-4 and MVPT-4 subscale raw scores exhibited several weak to strong, positive and statistically significant associations (rho = .385 to .600, p = .036 to .001). Australian children appeared to complete the TVPS-4 without any cross-cultural issues. The study findings suggest that the TVPS-4 assesses some similar motor-free perceptual abilities as the DTVP-3 and MVPT-4. This study provides some preliminary insights about the TVPS-4’s convergent validity with the Australian context. The primary clinical implication is that the study findings add to the TVPS-4’s body of validity evidence. Further research studies are recommended.
