• Resumen

  • OBJECTIVE. Having access to high-quality, rigorously developed, valid visual�motor integration assessment tools is the first step in the process of providing effective clinical services to children presenting with visual�motor integration problems. The aim of this study was to examine the factor structure of four visual�motor integration instruments through factor analysis.

    METHOD. The participants included 400 children ages 5 to 12, recruited from six schools in the Melbourne metropolitan area, Victoria, Australia. Children completed the Developmental Test of Visual�Motor Integration (VMI), Test of Visual�Motor Integration (TVMI), Test of Visual�Motor Skills�Revised (TVMS�R), and Slosson Visual�Motor Performance Test (SVMPT). The factor analysis was completed using SPSS.

    RESULTS. Results indicated that the VMI displayed six factors; TVMI, three factors; TVMS�R, four factors; and SVMPT, three factors.

    CONCLUSION. The VMI, TVMI, TVMS�R, and SVMPT exhibited multidimensionality, and it is recommended that the instruments be revised to enhance their construct validity and unidimensionality.
