The convergent validity of the Developmental Test of Visual Perception - Adolescent and Adult, Motor-Free Visual Perception Test - third edition and Test of Visual Perceptual Skills (non-motor) - third edition when used with adults.
Objective: The objective of the study was to investigate the convergent validity of the Developmental Test of Visual Perception - Adolescent and Adult (DTVP-A), the Motor-Free Visual Perception Test - third edition (MVPT-3) and the Test of Visual Perceptual Skills (non-motor) - third edition (TVPS-3...

Method: Two hundred and twenty-one participants aged 20+ years (49 with and 172 without neurological impairment) completed the DTVP-A, MVPT-3 and TVPS-3. Spearman rho correlation coefficients were used to analyse the convergent validity of the three tests. Results: The DTVP-A (non-motor) total score was significantly correlated (p<0.01) with the MVPT-3 and the TVPS-3 total scores (rho = 0.73 and rho = 0.75 respectively). The MVPT-3 total score was also significantly correlated (p<0.01) with the TVPS-3 total score (rho = 0.79). The DTVP-A figure-ground subscale was found to be significantlycorrelated (p<0.01) with TVPS-3 subscales 1 to 7 with rho coefficients ranging from 0.36 to 0.56, as was the DTVP-A visual closure subscale (rho coefficients ranging from 0.43 to 0.64) and the DTVP-A form constancy subscale (rho coefficients ranging from 0.51 to 0.64). The DTVP-A total score was also significantly correlated (p<0.01) with subscales 1 to 7 of the TVPS-3 (rho coefficients ranging from 0.48 to 0.68). Moreover, the TVPS-3 total score was significantly correlated (p<0.01) with the figure-ground, visual closure and form constancy subscales of the DTVP-A (rho = 0.62, rho = 0.65 and rho = 0.68). Furthermore, the MVPT-3 total score was significantly correlated (p<0.01) with the figure-ground, visual closure and form constancy subscales of DTVP-A (rho = 0.59, rho = 0.68 and rho = 0.65 respectively) and with subscales 1 to 7 of the TVPS-3 (rho coefficients ranging from 0.53 to 0.70). Conclusion: The DTVP-A, MVPT-3 and TVPS-3 exhibited moderate to high levels of convergent validity. The clinical implications of the findings of the study are that the DTVP-A, MVPT-3 and TVPS-3 appear to be measuring similar visual perceptual skills, but it is also important to note that the three tests all assess the visual perceptual skills in different ways. pubtype: Academic Journal doctype: research tables/charts Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
