Nurses in the training group were given training on aggression and the use of BVC.

Nurses in the control group were not trained, till the study ends.

After obtaining verbal consent from the nurses who met the inclusion criteria of the study before the pre-test was applied to the nurses, the nurses who volunteered to participate in the study were randomized within their own clinic using the simple randomization method. For this, after the data collection form was distributed before the pre-test, the nurses were asked to write the letter that came to them on the data collection form and not forget it. In order for nurses to be included in the training or comparison group, the letter A, written on the closed papers in the box prepared for simple randomization, represents the Education group, and the letter B represents the comparison group.

The scale has a 5-point Likert-type rating system ranging from strongly disagree (1) to strongly agree (5) and consists of 29 items. The items have two subscales: functional (functional - acceptable / healthy response) and dysfunctional (dysfunctional - unacceptable / undesirable aggression). For each subscale, the average of the relevant item scores will be calculated.

A score of "1" is given in the presence of each item of the BVC, and "0" in the absence of it. In the next evaluations of the patient, if there is an increase in the relevant item compared to the previous one, the behavior score is scored as "1", the habitual or same level behavior is considered absent and scored as "0". If there is no more in the case of a patient with a flood than before, the relevant item score should be "0". If an increase in the level of exuberance is observed, it should be scored as "1". After the six items are scored in this way, the evaluation is made over the total score. A total score of "0" indicates that the patient has a low severity risk level. "1- 2 points" indicates moderate risk of violence and necessitates measures to prevent violence. "3-6 points" refers to a high risk of violence.
