Aim: The purpose of this study was to use a variety of methods to evaluate and cross-validate the reliability estimates of the quality of schoolwork performance measures in the School Version of the Assessment of Motor and Process Skills (School AMPS)(1).
Methods: Split-half reliability was estimated based on School AMPS data from 6 194 students who had performed at least two school AMPS tasks. Two different split-half methods were used: splitting the School AMPS items vertically and splitting them horizontally. The Rasch equivalent of Cronbach’s alpha for the full School AMPS evaluation and standard error of measurement (SEm) were also considered.
Results: All three methods yielded high reliability coefficient estimates (r ≤ 0.70) and overall SEm was low.
Conclusions: From a practice perspective, the results of this study are of clinical importance as they provide evidence that occupational therapists can have confidence in the consistency of the School AMPS measures when they are used in the process of making decisions about individual students, planning interventions, and later performing followup evaluations to measure the outcome.
