The mean scores for all groups on the Laboratory Assessment Checklist were analyzed (Table 1). A higher score
indicates a more ergonomically sound workstation, with a maximum score of 33. To assess the degree to which participants improved their workstations, no “passing” or “failing” grades were assigned; rather, the data were examined on a continuous scale. Before the study, all groups obtained mean scores between 15.25 and 17.81 (see Table 1). A one-way ANOVA revealed no statistically significant difference between the pretest values across groups (p < .05). The posttest
mean scores revealed improvements for the education group (Group 2) and the education–training group (Group
3). The control group, however, experienced a decrease in score (Group 1).
