The validity and reliability of developmental test of visual perception-2nd edition (DTVP-2).
The Developmental Test of Visual Perception-2nd edition (DTVP-2) is frequently used by occupational therapists to evaluate school-age children. It is important that therapists use assessments with established validity and reliability. This study investigated the convergent validity and internal consistency of the DTVP-2. Forty-five healthy participants from Australia, aged 6-12 years, completed the DTVP-2, the Beery-Buktenica Developmental Test of Visual-Motor Integration-6th edition (VMI), and the Test of Visual Perceptual Skills-3rd edition (TVPS-3). A Spearman rho correlation coefficient was used to investigate the DTVP-2's convergent validity and Cronbach alpha coefficients were used to determine the DTVP-2's internal consistency. Statistically significant correlations between the DTVP-2, VMI, and TVPS-3 total scale scores and subscale scores were found. Internal consistency of items for the DTVP-2, VMI, and TVPS-3 total scores was >0.80 and internal consistency of items for subscale scores was >0.70. The DTVP-2 exhibited evidence of convergent validity with the VMI and TVPS-3, and moderate to high levels of internal consistency.
