Normative data of developmental test of visual motor integration for Chennai population

Objectives: The main purpose of this study was to establish normative data of the developmental test of visual-motor integration (VMI) among Chennai population. The study was also intended to (a) identify performance of chennai population on Principal test of VMI and Supplemental test of Visual Perception (VP) and Supplemental test of Motor coordination (MC) (b) To find the gender difference on performance of Principal test of VMI,Supplemental test of VP and Supplemental test of MC among Chennai population. Methodology: A quantitative research study. A total of 400 participants aged 15 to 19 years were engaged in the study from regular schools and Colleges located in Chennai using a convenience sampling method. The study participants were administrated with the Beery-Buktenica Developmental Test of VMI, 6th edition-long form. Results: The study found a statistically significant difference in the performance of a developmental test of VMI between each age group (F = 5.831, P = 0.001). The finding revealed that there was no gender difference in the principal test of VMI and the supplement test of MC. But there was a significant difference in the supplemental test of VP while comparing both genders (t = 2.76, P = 0.006). Girl's mean score in supplemental test of VP is higher relative to the boy's mean score in supplemental test of VP. Conclusion: The established normative data can be used in the evaluation of VMI and to plan the intervention and to identify effectiveness of the therapy.
