Purpose
The purpose of this paper is to examine the etiological model of cyberbullying behaviors among Thai adolescents, testing the hypothesis that the constructs of theory of planned behavior (TPB), including self-esteem, will influence and have impact on cyberbullying intention and behaviors.
Design/methodology/approach
Structural equation modeling (SEM) was used to analyze the data. Self-administered questionnaires were used among multi-stage stratified random samples from secondary schools in the Bangkok. The sample size consisting of 354 subjects included those who were victims (44.7 percent), perpetrators (33.1 percent) and witness (67.8 percent).
Findings
The SEM showed subjective norm (SN) to be the most direct influential factor of cyberbullying intention and behaviors, followed by attitude toward cyberbullying (Intention β=0.31, 0.24; p=0.01, Behavior β=0.09, 0.07; p=0.012 and 0.05, respectively). However, the SEM revealed that all variables from TPB including self-esteem in the equation can explain the variation scores of intention and cyberbullying behaviors at 54 and 67 percent levels (adjusted R2=0.54 and 0.67), respectively. The SEM showed that model modification indices indicate a good fit to the data (χ2=0.00, df=0, p>0.05, CMIN/df=0, GFI=1, AGFI=1, CFI=1 and RMSEA=0).
Research limitations/implications
The experiences or witness of family violence and support at school level, which is supposed to mitigate the bullying problems, were neglected from this study.
Practical implications
The preventive measures for cyberbullying behaviors among adolescents should involve activities fostering self-esteem, developing proper attitude and SN to prevent cyberbullying. The initiatives and developed school supportive system for adolescents to understand how to control themselves when engaging in social network are imperative. However, for future research, family violence witness and attempt to lure the cyberbullying victims into offline meeting should be explored more.
Social implications
TPB and the use of social media should be taken into account for planning and designing appropriate intervention to reduce and eliminate cyberbullying among all stakeholders in both public and private sectors in the area of health and educational institutes in order to endeavor and to advocate the anti-cyberbullying policy in Thailand.
Originality/value
TPB and self-esteem explained a substantial portion of and more modest but significant amount of variance in cyberbullying intention and behaviors. However, SN and attitude toward cyberbullying which was found to be most influential factors could be the useful information for designing intervention toward cyberbullying prevention for Thai adolescents and advocate implementing the anti-cyberbullying policy in Thailand.
