The study was conducted at two New Jersey
locations of a petrochemical research and develop-
ment facility. In 1994, 373 employees responded
``yes'' to a site wide e-mail survey asking whether
they used a VDT for two or more hours a day.
Employees meeting the above criteria were
assumed to be at risk of developing VDT-related
musculoskeletal injuries; these employees were
encouraged to attend a VDT training program
and to complete a self-administered questionnaire
prior to attendance. A total of 292 employees
(79%) completed the baseline self-administered
questionnaire and attended training.
