Work-related back pain causes limitations in activity and decreased productivity. Modifying ergonomic work behaviors along with exercise can help reduce back pain symptoms. This quasi-experimental research aimed to investigate the effects of self-efficacy promoting program on work-related back pain preventive behaviors among garbage collectors under the local government organization on self-efficacy in the practice of preventing work-related back pain, outcome expectation of preventing work-related back pain, practices of preventing work-related back pain, back muscle flexibility, ergonomic risk, and back pain, by applying the self-efficacy concept of Bandura and ergonomics principle. The participants were garbage collectors under the local government organization, Samut Prakan province, Thailand, using a purposive sampling method. The participants included 29 workers; they were divided into; 14 workers in the experimental group and 15 workers in the comparison group. The experimental group received the effects of a self-efficacy promoting program on work-related back pain prevention, with four activities. The program activities included learning, successful models, encouraging and goal setting. Data were collected by using questionnaires, back pain assessment form and REBA (Rapid Entire Body Assessment) before and after the intervention at week 5 and week 7. The results revealed that after the intervention in the 5th and 7th week, the experimental group was statistically significantly higher in self-efficacy (M5th 59.29+3.07; M7th 56.43+4.03) outcome expectation (M5th 45.50+4.22; M7th 39.93+1.69) practices of preventing work-related back pain (M5th 44.64+4.34; M7th 42.57+1.50) and back muscle flexibility scores (M5th 14.57+5.18; M7th 15.66+7.00) than before the intervention (Mpre45.64+2.27; Mpre37.00+1.71; Mpre38.00+4.24; Mpre9.84+5.01,respectively) and higher than the comparison group (p <0.05) and had a statistically significant decrease in back pain scores (M5th 0.86+0.770; M7th 0.50+0.855) than before the intervention (Mpre4.24+2.016) and lower than the comparison group (p <0.05). The mean score of ergonomic risk (M5th 6.57+1.651; M7th 6.14+1.167) lower than before the intervention (Mpre8.00+1.240) and lower than the comparison group (p <0.05) in week 7. This finding suggested that occupational health nurse or public health officer at the local government organization can apply this program to promote self-efficacy to prevent work-related back pain among the garbage collectors’ behavior.
