3.5. Perceived control over the work environment
Responses to the knowledge and exercise of chair
adjustability questions showed a positive change for the
groups receiving the training as compared to the control
group, though not statistically significant (p40.05). An
observed positive change was noted in the responses to the
knowledge of workstation adjustability questions for the
chair+training (pre-intervention M ¼ 0.70; post-intervention
M ¼ 0.76) and training-only groups (pre-intervention
M ¼ 0.81; post-intervention M ¼ 0.90) as compared to the
control group (pre-intervention M ¼ 0.85; post-intervention
M ¼ 0.82). However, no significant change was found
for the knowledge and exercise workstation adjustability
questions.
