Effect of health educational intervention based on the educational phase of the PRECEDE-PROCEED model on the promotion of preventive behaviors of brucellosis in the villagers of Minoodasht, Iran

Aims Annually, more than half a million people worldwide are infected with brucellosis. Education is one of the basic strategies in controlling and preventing this disease. The PRECEDE model provides a clear framework for planning to change behavior. The factors affecting the behavior in the educational diagnosis stage of this model are categorized. This study aimed to determine the effect of educational intervention based on the educational phase of the PRECEDE-PROCEED model on the improvement of preventative behaviors of brucellosis. Materials & Methods This semi-experimental study was carried out on 150 villagers of Minoodasht, Iran, in 2019. The subjects were selected by stratified sampling in two control and intervention groups. Seventy-five people were assigned to each group. Data collection tools were the valid and reliable questionnaire based on the educational structures of the PRECEDE-PROCEED model and a demographic questionnaire. Data of the two groups were collected before and three months after the educational intervention. Data were analyzed using SPSS 19 software through T, Chi-square, and exact Fisher tests. Findings There was no significant difference between the two groups in demographic variables and enabling factors before the intervention (p>0.05). In contrast, there was a significant difference between the two groups in the enabling factors and preventive behaviors of brucellosis three months after the educational intervention (p<0.05). Conclusions The educational intervention based on the educational diagnosis phase of the PRECEDE-PROCEED model effectively promotes brucellosis prevention behaviors in the villagers.
