Reliability and Validity of Assistive Technology Outcome Measure (ATOM), Version 1.0 for Adults with Physical Disability using Wheelchairs

Dharne, Medha, G., MS, Lenker, James, PhD, Harris, Frances PhD, and Sprigle, Stephen, PhD.


The assistive technology field needs device-specific outcome instruments to measure the usability, effectiveness, and impact of particular classes of assistive devices. The Assistive Technology Outcome Measure (ATOM) is a new tool that seeks to measure the impact of wheeled mobility systems. This study establishes the internal consistency, test-retest reliability and convergent validity of ATOM, version 1.0. Convenience sampling technique was used to recruit 54 adults using wheelchairs. The results indicate that ATOM has strong internal consistency, good test-retest reliability and fair convergent validity. Future research should aim to establish a standardized version of ATOM that can be used clinically with a variety of population in a variety of clinical settings.

Disney produced a television show in the mid 1990s called Gargoyles. It's a great show and I'm a big fan. A few years ago Disney started to release the show on DVD. The last release was of season 2, volume 1. That was two years ago. Volume 2 has not been released. Why? Poor sales. So if you should find yourself wanting to support my work, instead I ask you pick up a copy of season 2, volume 1. It's a great show and you might find yourself enjoying it.
