Abstract

The objectives of this research were 1) to study the level of bullying behavior among lower secondary school students, 2) to investigate the factors that affect bullying behavior among lower secondary school students, and 3) to identify the factors that influence bullying behavior among lower secondary school students. The sample consists of 240 lower secondary school students selected through simple random sampling. Data were collected using questionnaires, and the statistics used for data analysis include frequency, percentage, mean, standard deviation, person’s product moment correlation coefficient, and stepwise multiple regression analysis.
The research results were as follow: 1) the overall factors influencing bullying behavior among lower secondary school was at a high level; 2) the factor affecting of bullying behavior among lower secondary school students was at moderate level with 7 factors identified include self-esteem, frustration, relationships between students and peers, relationships between students and family, relationships between students and teachers, online media usage, and religious beliefs; and 3) the factors affecting bullying behavior among lower secondary school students consist of 3 factors: relationships between students and peers, relationships between students and family, and online media usage. The collectively explain the bullying behavior of lower secondary school students about percentage of 21.2 at the level of .001 and can be used to develop a predictive equation. The predictive equation for bullying behavior of lower secondary school students as follows: Regression equation: Y ̂=2.455 + 0.168X_3 + 0.316X_4 + 0.161X_6 Standardized regression equation: (Z_y ) ̂=0.185Y_x3 + 0.331Y_x4 + 0.215Y_x6
