Validation and Field Testing of an Ergonomic Computer Use Checklist and Guidebook

The authors developed a validated office ergonomics checklist that focused on outcomes instead of workstation features. The workstation is evaluated primarily through observed working postures and movement patterns while the subject performs their usual tasks. A guidebook for the improvement of computer workstations is keyed to the checklist, to lead the user in reducing risk factors and improving workstation ergonomics. The checklist was first validated in a field test with three expert evaluators. The checklist and guidebook were later tested with a large employer and used as a self-evaluation instrument, by a co-worker, and by an Ergonomics Coordinator with training and experience. Workstations were evaluated by an independent ergonomist before and after interventions were made. Results indicated that the checklist and guidebook were effective in making significant improvements in workstation conditions when administered by an Ergonomics Coordinator, but not when used as a self-assessment or by an untrained co-worker.
