This study was designed to test the concurrent validity of the revised Task-Oriented Assessment (TOA) component of the Bay Area Functional Performance Evaluation (BaFPE) (Bloomer & Williams, 1979) with Part 1 of the American Association on Mental Deficiency Adaptive Behavior Scale (ABS) (Nihira, Foster, Shellhaas, & Leland, 1969, 1974) and to develop a means of interpretation for the numeric scores on the TOA. Both measures were administered to 67 psychiatric inpatients within the first 14 days of admission. Low to moderate correlations were found between the TOA tasks and functional parameters and the ABS domains. Because the TOA shows low concurrent validity with the ABS, only limited interpretive descriptions for TOA scores could be developed.
