Preeclampsia is a leading cause of maternal mortality and morbidity worldwide. The high incidence of preeclampsia is due to the low prevention behavior of preeclampsia. The preeclampsia tree education model is expected to improve preeclampsia prevention behavior. Produce a proper preeclampsia tree education model and its effective application for the prevention of preeclampsia. This type of research is Research and Development. Test model validation by obstetricians and gynecologists, material experts, media experts and linguists. The model application test used a quasy experiment design (pre-test and post-test with control group design). The research subjects were 64 pregnant women who were divided into intervention and control groups. The independent variable is the educational model of the preeclampsia tree and the dependent variable is the knowledge, attitudes and behavior of village health worker and pregnant women. Data analysis used paired t-test, Wilcoxon test, independent t-test and Mann Whitney test. The results of material validation obtained a mean of 90 (very feasible) p-value 0.001, the model test obtained a mean of 87.6 (very feasible) p-value 0.012 (p <0.05). The unpaired data test (post-test) on the knowledge of pregnant women obtained p-value 0.000 (p <0.005), attitude p-value 0.000 (p <0.05), and behavior pvalue 0.000 (p <0.05). The preeclampsia tree education model is feasible as a model and guideline and its application is 10 times for pregnant women have a better effectiveness on the knowledge, attitudes and behavior of preeclampsia prevention than the control group.
