Bullying and cyberbullying are important global issues with negative consequences for physical and mental health in education. The objective of this study was to analyze to what extent some dimensions of emotional intelligence predict certain manifestations of bullying and cyberbullying in adolescents. The total number of subjects recruited in compulsory secondary education schools, was 309 (53.1% female). Their ages ranged from 12 to 16 (M = 14.17, SD = 1.4). The used instruments were the school violence questionnaire and the emotional coefficient inventory; the study design was cross-sectional. Results showed that the score increases on some scales (adaptability, stress management, and interpersonal) involved a greater risk of increasing the likelihood of social perception the different manifestations of school violence. However, in the general mood, the increase in this variable score implied lower perceiving in likelihood of violent behavior. It is important to take into account preventive actions aimed at improving school life and, above all, to alleviate difficulties in managing stress, adaptability, and interpersonal relationships.

The rise of technology has increased risks such as problematic internet use or cyberbullying. Data show that there is problematic use of the internet, which has important repercussions academically, personally, socially and for health. The objective of this study was to identify different profiles that vary according to intra- and interpersonal conflicts related to internet use. In addition, this study aimed to examine whether there are significant differences in bullying and cyberbullying among adolescents with a conflict related to internet use. The study participants were 810 students of Compulsory Secondary Education (M = 13.99, SD = 1.32). The Questionnaire on School Violence and the Questionnaire of Experiences Related to Internet was use. The latent profile analysis identified four different types of conflicts related to internet use: (a) high levels in intra- and interpersonal conflicts; (b) low levels intra- and interpersonal conflicts; (c) moderate intra- and interpersonal conflicts and (d) very high levels in intra- and interpersonal conflicts. The results of the study indicated that there were significant differences in the manifestations of school violence between the profiles. This study assists in educational programs to prevent conflicts related to internet use and school violence through emotional adjustment.

The use of mobile phones has great benefits for communication. However, evidence has shown that problematic use, such as cyberbullying, can also be associated with mobile phones. In this sense, emotional regulation plays an important role. The objective of this study was to identify different groups that varied in terms of conflicts related to problematic mobile phone use (namely, maladaptive communication and emotional patterns). Furthermore, the study aimed to examine whether there were significant differences in the dimensions of emotional intelligence and cyberbullying between adolescents with a mobile phone use problem. The study participants were 810 students aged between 12 and 16 years. The Emotional Coefficient Inventory questionnaire about cyberbullying and a questionnaire on experiences related to mobile phones were used. The cluster analysis identified three different types of mobile phone use: A group displaying no problematic use, a group displaying moderately problematic use, and a group displaying problematic use. The study results motivate carrying out stress management programs, emotional re-education, and other actions that reinforce emotional intelligence.
