BACKGROUND: Changing human behavior for the purposes of improving the way people workis an integral part of most educational interventions. This study aimed to evaluate the effect of amodel based on the theory of planned behavior (TPB) on correct principles of manual materialhandling (MMH) among male soldiers.SUBJECTS AND METHODS: This study was a quasi‑experimental, pretest‑posttest research witha control group. Furthermore, 140 soldiers, from an area located in the city of Bandar Abbas, Iran,were selected through a simple random sampling and they were divided into two groups: interventionand control (70 subjects in each group). The data were collected using a three‑part questionnaireincluding demographic information, the theory constructs, and MMH behavior. The intervention groupwas given the relevant education, and after 2 months, the both groups were evaluated.RESULTS: Based on regression analysis, attitude toward behavior and perceived behavioral controlwere predictors for correct principles of MMH. There were significant differences between the meanscores of the theory constructs before and after the education in intervention group (P < 0.001);however, no significant differences were observed in the theory constructs in the control groupafter the intervention. Before the education, the mean score of MMH of the intervention groupwas 38.30 ± 6.45; but after, the education, this changed into 44.20 ± 6.01, and significantlyincreased (P < 0.001).CONCLUSIONS: Educational intervention based on the TPB was effective in improving behavior forcorrect MMH in soldiers. Thus, the use of such educational programs according to the constructs ofthe planned behavior theory is recommended.
