The role of the family in preventive behaviors against brucellosis is important, so this study was conducted to determine the relationship between preventative behaviors of brucellosis and family-based empowerment models in women in families with brucellosis patients in Iran.Instrument & Methods 200 people participated in this descriptive study through the multistage cluster method. Data were collected through demographic questionnaires, awareness, attitude, self-efficacy, and self-esteem and behavior. Data were analyzed using SPSS software and independent T-tests, one-way analysis of variance, and Pearson and Spearman correlation and regression. Findings 96 (48%) participants had a history of brucellosis, 174 (87%) had a history of contact with livestock, 131 (65.5%) had a history of consumption of unpasteurized dairy products (r=-0.218, p=0.003). Based on the independent t-test, a significant relationship was observed between pasteurized dairy consumption and housekeeping with preventive behavior (p=0.039) (p=0.455). Variance analysis test showed a significant relationship between the level of education and preventive behavior (p=0.002). According to the linear regression model, the relationship between self-efficacy and behavior was significant (p0.001), and self-efficacy had more predictive power than other constructs. Conclusions In countrywomen, self-efficacy plays an important role in predicting behavior. In order to promote preventive behaviors against brucellosis, people's self-efficacy should be improved.
