의사결정나무분석을 이용한 학교폭력 주변인 행동유형 예측모형 탐색

초록

The purpose of this study was to predict the behavioral types among school violence bystanders, focusing on the interactions between ecological systemic factors affecting school violence. For this, 1,984 middle and high school students were surveyed using a questionnaire that consisted of 16 factors derived from the ecological systemic theory. The interactions between these factors predicting behavioral types (i.e., the bully-follower, outsider, and victim-defender) were analyzed using the data mining's decision tree analysis. Results are as follows. First, in the decision tree model of bully-follower, the bully-followers were most often predicted by the following factors: strong influence of violent media, perceived social tolerance to violence as being more tolerant, low level of empathy, and interactions with peer groups. Second, in the decision tree model of outsider, the outsiders were most often predicted when there were: less frequent interactions with teachers, not well-established school violence prevention safety systems existing, lack of conflict resolution strategies, and less influence of violent media. Third, in the decision tree model of victim-defender, the victim-defenders were most often predicted by the following factors: more frequent interactions with teachers, less influence of violent media, perceived social tolerance to violence as being more intolerant, and low level of social anxiety. Based on the results of this study, to prevent and reduce school violence, we discussed the importance of studying school violence bystanders and developing counseling and educational approaches for them. Directions for future research were also suggested.
