A preliminary study of the predictive value of the IPAT.
Articulation test scores for 278 subjects with cleft palate were compared with the normative data of Templin and Darley on the Iowa Pressure Articulation Test and the Templin-Darley Screening test of Articulation. In addition the predictive value of the Iowa Pressure Articulation Test in relation to the need for secondary management was examined. The results indicate that, at no age level between four and ten years, do more than 9% of the subjects achieve the mean on the IPAT without secondary management. Examination of the data in regard to "risk rates" indicates that the IPAT is very useful in predicting the need for secondary management. Subjects who obtained scores of zero on the IPAT at four and one-half years of age had a 96% risk of requiring secondary palatal management.
