[Validation of a measurement instrument to evaluate computer access in people with physical disabilities]

The aim of this study was to develop an instrument to measure performance in computer tasks for persons with physical impairments. The objectives were to assure the content validity and the internal consistency of the test as well as the reliability of each task. The first step was to determine the mouse and keyboard actions necessary to use a computer. Resulting from these actions, 15 standardized computer tasks were designed as part of the test. To measure reliability and internal consistency, the test was administered twice to 19 persons without disabilities and 17 persons with disabilities. Reliability was established for most of the tasks and the test showed good internal consistency. This instrument could contribute to the improvement of occupational therapy interventions regarding computer access.
