Abstract: The purpose of this study was to establish the validity and reliability of Motor-Free Visual Perception Test - Revised (MVPT-R) for preschool children in Hong Kong. Validity was evaluated by investigating the content validity and construct validity evidence. The reliability of MVPT-R was evaluated by investigating the test-retest and internal consistency evidence. This research consisted of two stages. Stage one was an evaluation of the content validity. The instructions were translated into Cantonese. Six pediatric occupational therapists were invited to be the panel members to review the translated test instructions and the test items. Stage two was an investigation of reliability and construct validity. Sixty 4-year old children (30 boys and 30 girls) and sixty 5-year old children (30 boys and 30 girls) were recruited through cluster sampling. They were tested individually. Results from the expert panel review suggested that all the instructions showed fluency and correctness and also were equivalent to the semantic meaning of the original version of the MVPT-R. They also agreed to the relevance and the representativeness of all the test items. The test-retest reliability in the 4-year old age group and 5-year old age group was .63 and .79 respectively. The result indicates that MVPT-R was reliable to measure visual perception of the 5-year old children, but to measure the 4-year old children, care must be exercised. The internal consistency of the test was moderately high in both age groups. There was significant difference in the performance between 4 and 5-year old groups but there was no significant gender difference. The result suggests that only a single set of norms instead of separate sets of norms based on gender is required for 4 and 5-year old children. Norms developed in U.S.A. has found to be unsuitable for use in Hong Kong.
