Fifty-one of the 92 participants met the inclusion criteria. The sample included male and female workers between 21
and 55. Of this total, 7 participants withdrew because of job relocation or for personal reasons. The randomization process
resulted in 24 participants in Group 3, which received the education–training intervention; 16 participants in
Group 2, which received education only; and 11 participants in Group 1, the control group. ANOVA on the demographic
data revealed no statistically significant differences between groups (p ≤ .05).
