THE EFFECTS OF SELF-EFFICACY ENHANCEMENT PROGRAM TO PREVENT LOW BACK PAIN OF OFFICE WORKERS IN A PRIVATE HOSPITAL, BANGKOK
Keywords:
low back pain, office workers/ self-efficacyAbstract
This quasi-experimental research using two group pre test-post test designs aimed to examine the effect of a self-efficacy promotion program on the prevention of low back pain and level of lower back pain. The degree of flexibility of the back muscles and the degree of ergonomic risk were also assessed. Purposive sampling technique was used to recruit 60 office workers with lower back pain in a private hospital . Participants were then divided into experimental groups (n=30) and the control groups (n=30) based on their work location. The experimental group participated in the program for 4 weeks and the control groups received usual care. Program consists of educational activities related to lower back pain, ergonomics and working with computer, work station arrangement, and practice of back muscle exercises. Data was collected using self-administered questionnaire, muscle flexibility assessment and rapid office strain assessment (ROSA). Descriptive statistics including frequency, percentage, mean, standard deviation, Wilcoxon signed rank test and Mann Witney U test were used to analyze the data.
The results revealed that after receiving the program, the experimental group had higher mean scores on perceived self-efficacy in reducing low back pain and, self-care behaviors than the pretest and higher than that of the control group (p < .001), degree of flexibility of the back muscles was also significantly higher than before the experiment (p < .001). However, low back pain and ergonomic risk score was not significantly different between groups. Findings suggest that self-efficacy enhancement programs for the prevention of low back pain was effective in promoting self-care behaviors and could be applied to those with similar job characteristics.
