Sensory integrative dysfunction occurs in 5-10% of children. Various tests are used to identify sensory dysfunction in infants in South Africa but they have not been validated in this context. The purpose of this study was to explore the comparison of normative scores, construct validity and diagnostic accuracy of two standardised assessments: the Infant/Toddler Sensory Profile (ITSP), a parent report tool and the Test of Sensory Functions in Infants (TSFI), a therapist administered test on 60 infants. The sample was recruited from child day care facilities in the East Rand. Overall reliability of the ITSP was found to be within an acceptable range, while for the TSFI it was below an acceptable range. The TSFI had poor diagnostic accuracy for the total score on a number of sections. The divergent validity found between the sections of the two tests confirmed that they do not measure the same constructs of sensory processing.
