Reliability and Validity of a New Computer-Administered Pictorial Activity and Task Sort

Abstract

Development of a new pictorial activity and task sort and examination of its reliability and validity is described. The Multidimensional Task Ability Profile (MTAP) is the latest in a series of measures that use a combination of drawings and task descriptions in a self-report format to assess functional capacity. The MTAP is found to be reliable on a test-retest and split-half basis. The concurrent validity of the MTAP was examined in performance testing of lift capacity. Results demonstrate that the MTAP has good concurrent validity.
