INTRODUCTION - The aim of the study was to provide normative data on Test of Visual Perceptual Skills-3 (TVPS) in Indian Drivers as well as to examine the effect of education, age and gender. Also to assess the clinical utility in Indian population. METHODS One hundred and seven participants -57 males and 50 females aged 25 to 54 years stratified into 3 age group and 3 educational level completed the TVPS-3. Mean, standard deviation and decile were calculated for TVPS overall score and mean, standard deviation, quartile were calculated for TVPS-3 subtest score. One way ANOVA and t test were used to analyze the data. RESULTS The analysis demonstrated that education has a significant effect on TVPS 3 score, as evidenced by increasing TVPS score with education. Lower education contributed to poor test performance. One-way ANOVA between three age group and three educational years showed that as the number of educational years increases in any group there is statistically significant interaction. No significant age and gender effect was noticed as age group studied was younger and middle age group. TVPS subtest accuracy score of 16 was obtained in all subtest by 12 + educational group. CONCLUSION The findings indicated that education was associated with better performance on TVPS-3. We obtained normative references for the TVPS on an adult Indian drivers population. An accurate screening tool should lead to increased confidence for Occupational Therapists to assess visual perceptual skills for comprehensive driving assessments.
