The Effect of an Educational Intervention Program on the Adoption of Low Back Pain Preventive Behaviors in Nurses: An Application of the Health Belief Model.

Study Design Randomized controlled trial. Objective The purpose of this study was to identify the effect of a theory-based educational intervention program on the level of knowledge and Health Belief Model (HBM) constructs among nurses in terms of the adoption of preventive behaviors. Methods This pretest/posttest quasi-experimental study was conducted on 100 nurses who were recruited through the multistage sampling method. The nurses were randomly assigned to intervention and control groups. The participants were evaluated before and 3 months after the educational intervention. A multidimensional questionnaire was prepared based on the theoretical structures of the HBM to collect the data. Data analysis was performed using descriptive and inferential statistics. Results There was no significant difference in the mean values of HBM constructs prior to the intervention between the intervention and control groups. However, after the administration of the educational program, the mean scores of knowledge and HBM constructs significantly increased in the intervention group when compared with the control group (p < 0.0001). Conclusion The results of the current study revealed that the educational intervention based on the HBM was effective in improving the nurses' scores of knowledge and HBM constructs; therefore, theory-based health educational strategies are suggested as an effective alternative to traditional educational interventions.
