RESUMEN
Violent behaviour in the secondary education stage is a serious concern that comes from low emotional control. Judo is a sport that requires self-control and high emotional competence to mitigate aggressive behaviours. This research presents the objectives of analysing the correlations of different types of aggressive behaviours before an intervention program with those after said program, as well as study the effect of emotions on aggressive behaviours before and after the intervention program through multigroup structural equation modelling. A quasi-experimental study was planned. It used a pre-test-post-test design in a population of 139 secondary school students (M = 15.76; SD = 1.066). The instruments were an ad hoc questionnaire, the Schutte Self-Report Inventory and the Violent Behaviour at School Scale. The data show that the intervention decreased the correlations between different types of violent behaviours. The results show an increase in the effect of emotional intelligence on mitigating aggressive attitudes. The promotion and use of contact sports is necessary to prevent the emergence of aggressive behaviours within a school environment.
RESUMEN
Currently, many combat sports are pedagogically conceived as uneducational and unreliable for the development of young people. The present research aims to investigate the influence of a Judo intervention programme on the motivational climate towards sport, aggressive behaviour, emotional intelligence, and self-concept in secondary school students and to establish the relationships between them. This objective was broken down into (a) developing an explanatory model of the variables mentioned above and (b) testing the model equations through a multi-group analysis in terms of pre-test and post-test. The present study conducted a pre-post-test quasi-experimental design with a single experimental group. The sample consisted of a total of 139 adolescents (12.67 ± 1.066), 50.4% of whom were male (n = 70) and 49.6% female (n = 69). The results show that the intervention decreased all types of aggression and increased levels of emotional intelligence. An increase in social, physical and academic self-concept and decreases in the family and emotional areas were also observed. Finally, for the motivational climate, a tendency towards the ego climate to the detriment of the task climate was observed. It is concluded that the Judo intervention programme is effective in decreasing aggressive behaviour and effective in increasing levels of emotional intelligence and self-concept.
RESUMEN
The present research aims to analyse the psychometric properties of the AF5 questionnaire for its adaptation for use with young people during a lockdown period. Research was conducted with a sample of 534 students aged between 13 and 17 years (M = 14.49; SD = 1.805). Exploratory factor analysis was conducted using the FACTOR program and confirmatory factor analysis was conducted using the M-PLUS 7 program. Results indicate that a four-dimensional model is most appropriate for bringing together the emotional and physical dimensions. Further, 11 items were removed due to poor factor loadings. The majority of factors were directly and positively correlated (99%; p < .01). The data obtained supports conclusions that the AF-5 meets validity and reliability requirements for it to be considered a useful instrument for use with young people during the COVID-19 lockdown period.
