Abstract
OBJECTIVE: We examined the reliability of the Motor-Free Visual Perception Test-Revised (MVPT-R) and the Test of Visual-Perceptual Skills-Revised (TVPS-R) in 52 children with cerebral palsy. METHOD: The MVPT-R and TVPS-R were initially assessed by a single rater and then randomly assigned to the same rater or another rater after 6 to 14 days. RESULTS: For scale-level reliability of both tests, the intraclass correlation coefficients (ICCs) were high. The smallest real differences (SRDs) were largely acceptable. The OICCs of most subscale-level reliability of the TVPS-R were satisfactory. The SRD of each TVPS-R subscale score was notable (>29%). The internal consistency was high for both tests. CONCLUSION: The scale-level reliabilities of both tests were satisfactory in children with cerebral palsy. Although most subscales of the TVPS-R had acceptable test-retest or interrater agreement, all subscales of the TVPS-R had large SRDs, limiting their clinical utility.
