Test-Retest Reliability of the Motor-Free Visual Perception Test Revised (MVPT-R) in Children with and Without Learning Disabilities

Abstract

The Motor-Free Visual Perceptual Test Revised (MVPT-R) is an updated edition of the original test with the addition of four items and normative data for 9-11-year-old children. Test-retest reliability studies on the MVPT-R are not reported. The purpose of this paper is to report the test-retest reliability of the MVPT-R in children with and without learning disabilities. The MVPT-R was administered to 38 children with identified learning disabilities and 37 control children (aged 7-10 years) on two separate occasions within a 2.5 week window of time. Inter-rater reliability agreement between examiners was 99%. Intra-class correlations for perceptual quotient scores ranged from .63-.79 and perceptual age scores ranged from .69-.86. Pearson product moment correlations for perceptual quotient scores ranged from .70-.80 and perceptual age scores ranged from .77-.87. Results suggest moderate test-retest reliability for the MVPT-R with more stability in visual perceptual scores for children with learning disabilities. This information will be helpful for therapists using the MVPT-R as a descriptive measure for children.
