  • 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 ICCs 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
