• Resumen

  • Paediatric occupational therapists often assess and treat school-age children and youth presenting with visual perceptual dysfunction. It is, therefore, important that occupational therapists use visual perceptual instruments that possess sound measurement properties (such as validity, reliability, responsiveness and clinical utility). The Motor-Free Visual Perception Test - Revised (MVPT-R) is an instrument frequently used by paediatric occupational therapists. Clinicians need to be cognisant of the measurement properties of the assessments they use in order to provide the best level of care for the paediatric clients they serve. Therefore, a review and critique of the MVPT-R is presented.

    Even though the MVPT-R has been revised recently, little has been done to address issues related to its reliability and validity. Evidence of criterion-related validity and construct validity, in particular, is still lacking. The rationale for measuring motor-free visual perception is also not well developed and needs to be expanded in the MVPT-R manual. In addition, the issue of summing the scores from the five MVPT-R subscales is questionable. What the final MVPT-R summed score really measures in terms of a screening evaluation or diagnosis is also lacking. At this stage, this instrument should be used and interpreted by occupational therapists with caution
