The most compelling finding of this study was that of
the three groups analyzed, the group that received the education–
training intervention (Group 3) obtained the highest
mean score on the Laboratory Assessment Checklist posttest
and demonstrated a large effect size and substantial percentage
of no overlap compared with both the education-only
and the control groups. This finding implies that of the three
groups, members of the education–training group improved
their workstation design and body positioning most significantly.
Participants in this group experienced a large change
in their scores pretest to posttest and relative to the other
groups. The intervention designed for this study was
grounded both in the literature and in the philosophies of
occupational therapy, ergonomics, and health education.
The central themes of the intervention included an emphasis
on client centeredness, environmental adaptation, task analysis,
feedback, and participation, in addition to peer support
and involvement and multimodal learning. These emphases
appear to have had a substantial impact on the participants
in their work environment, without excessive time
requirements.
