Abstract:
The purpose of this research study was to examine factors related to inter-institutional rumbles in male vocational students in Bangkok Metropolitan and perimeter areas. The participants were 300 male vocational students who were classified into 2 groups: 150 participants who have engaged in inter-institutional rumbles at least once in the last six months and 150 participants who have never had such experiences. Research instruments were Personal Data Questionnaire, Aggression Questionnaire, Self-esteem Scale, Collective Self-esteem Questionnaire, Emotional Intelligence Scale, Independence from Peer Norms Scale, and Media Influence Questionnaire. Data were analyzed by using the Discriminant Analysis with a stepwise method. The Wilks Lambda was examined to determine the factors that helped predict inter-institutional rumbles in these participants. Findings indicated that four factors helped predict inter-institutional rumbles in male vocational students. These factors were: aggression, independence from peer norms, reception of media influence, and emotional intelligence. These factors significantly discriminated participants with and without inter-institutional rumbles and yielded the total predictive discriminant efficiency of 80.00 percent.
