Reliability and validity of the Toglia Category Assessment Test.
The aim of this study was to establish interrater reliability, internal consistency reliability, and both concurrent and discriminant validity for the Toglia Category Assessment (TCA), a test of cognitive categorization. This study was based on an examination of categorization skills in clinical samples, using both the Toglia Category Assessment as well as the Riska Object Classification (ROC) test. The study sample consisted of 35 adult persons with brain-injury and 35 persons with chronic schizophrenia (n = 70). Correlations between scores of the two different tests and the two different samples were computed using Pearson's Product Moment Correlation Coefficients. Both inter-rater reliability, internal consistency, and concurrent validity were established for the TCA. These results suggest that the Toglia Category Assessment and Riska Object Classification tests may address different cognitive abilities. The Toglia Category Assessment appears to be a more sensitive test than the Riska Object Classification in that it provides an elaborate cognitive profile.
