The experimental design used was a non-randomized pretest-posttest control group design. The research location is a Kindergarten in Bangkalan, with 20 preschool children in grade A and B as subjects. This study uses a measurement instrument in the form of an Aggressiveness Scale which is filled in based on observations and self-reports of children from parents. The collected data were tested using the non-parametric difference test, Wilcoxon. The results of this study were viewed from the aspect of aggressive behavior, namely: 1) physical aggression; 2) Verbal aggressive; and 3) Passive aggression. From the test results it was found that the experimental group experienced a decline and the untreated control group did not experience a decrease, so it can be said that the hypothesis in this study was accepted.
