Purpose - As occupational therapists embrace evidence-informed and occupation-centred practice, the use of standardised visual perceptual tests remains a strong feature of typical paediatric practice. Yet, the research evidence for the use of such tools is inconclusive at best. This study compared the results of the Test of Visual Perceptual Skills (TVPS) with a checklist of reported functional difficulties in 30 children attending occupational therapy. The purpose of this paper was to determine the usefulness of visual perceptual testing in relation to occupation-centred practice. Design/methodology/approach - A descriptive correlational study design was used. Participants were 30 primary school-age children who were on a paediatric occupational therapy caseload. An additional 30 typically developing children participated in the development of the checklist. Findings - Correlations were found between reported functional visual skill difficulties and two subtests of the TVPS (visual memory and visual discrimination). No correlation was found between the reported functional difficulties and any of the other five subtests of the TVPS or the total score. Originality/value - Results highlight the weak relationship that existed in this study between standardised measures of visual perception, as measured by the TVPS, and functional difficulties. Therapists are cautioned to explore both the evidence base for continued use of standardised visual perceptual measures to inform occupation-centred practice and the need to embrace a more comprehensive person-centred approach to visual perceptual assessment.
