The violence which was done in health instutitions includes verbal or behavioural threats, physical attacks or sexual attacks which comes from patients, patient relatives or another individual and which forms a risk for the health worker. The health workers are attacked 16 times more than the individuals which work at the other areas.

In this study, the 2-factored cross-classification model was applied, because there are qualitative valued data. There are 10 violence levels in the model. We have tested that which level is most efficient with a certain probability level  and we have found the best estimator and a single solution vector.
