These perceptual skills also influence children's behavioural characteristics. Well-constructed, norm-referenced standardised tools are vital for assessing visual-perceptual skills. Since ethnicity and cultural background may influence the performance of perceptual tasks, the proposed norms for any assessment tool need to be validated for specific populations. Hence, the current study aimed to develop norms in the Indian context for the Developmental Test of Visual Perception, third edition (DTVP-3), and compare the obtained norms with the norms established in the United States of America.Methods: One hundred and thirty-seven healthy children (mean age: 9.5 ± 1.7 years, range: 7-12 years, 67 females) participated in the study. Visual-perceptual functions including eye-hand coordination, copying, figure-ground, visual closure, and form constancy, were assessed and compared with age-matched norms provided in the test manual. Internal consistency of DTVP-3 was evaluated using Cronbach's Alpha correlation coefficients.Results: Significant differences were observed between the study groups and the given norms for assessment of the abilities of eye-hand coordination, copying skills and visual figure-ground (p < 0.05). No significant difference was found for visual closure and form constancy subtests. Cronbach's alpha coefficients for the five subtests ranged from 0.70 to 0.91 while the composite indexes had coefficients from 0.90 to 0.93.Conclusion: The DTVP-3 showed acceptable limits of internal consistency when tested in a group of children from South India. Region-specific norms need to be used for each of the subtests. pubtype: Academic Journal doctype: research tables/charts Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
