INTRODUCTION: Brucellosis is one of the common diseases between humans and animals. The
purpose of this study was to investigate behavioral determinants of brucellosis incidence among
stockbreeders and their family members in a rural area based on the PRECEDE model.
MATERIALS AND METHODS: This cross-sectional study was carried out among 540 stockbreeders
and their family members in Northeastern Iran in 2019. Sampling was done in two stages including
stratified sampling and random sampling method. Data collection was conducted by a valid and
reliable questionnaire developed based on the PRECEDE model. Data were analyzed using SPSS16
through Pearson correlation coefficient, independent t-test, and ANOVA. Furthermore IBM SPSS
AMOS version 20 was used for the path analysis.
RESULTS: The mean age of the participants was 39.02 ± 16.41 years, of whom 53.1% and 46.9%
were men and women, respectively. About 23.9% of the participants had a history of brucellosis in
their families. Enabling factors were the most important determinant of self-efficacy and self-efficacy
was the most important determinants of behavior. Evaluation of the chi-square indicators, chi-square
ratio to degree of freedom, root mean square error of approximation, adjusted goodness of fit index,
parsimony comparative fit index, comparative fit index, incremental fit index, and parsimonious normed
fit index indices indicated that the model was well fitted and there was a positive and significant
relationship between the predisposing, enabling, and reinforcing factors on the one hand and behavior
on the other. chi-square indicators, chi-square ratio to degree of freedom, root mean square error
of approximation, adjusted goodness of fit index, parsimony comparative fit index, comparative fit
index, incremental fit index, and parsimonious normed fit index
CONCLUSION: Designing and implementing health plans based on the PRECEDE model with more
emphasis on self-efficacy as the most important behavioral determinants can bring about a positive
effect on enhancing the brucellosis preventing behaviors.
