|Opis:||Currently there is an increase in various forms of aggressive and delinquent behaviour among youth in school environment and in the society in general. Therefore, the long-term study of the risk factors that are predictive of aggression is essential for identifying and predicting the aggression and delinquency outcomes. The ability to understand the development of aggressiveness and its various forms is crucial for the experts in various areas of psychological work: in clinical and pedagogical environment, in psychotherapy and in mental health prevention programs. Once the factors of aggressive behaviour development are identified, the guidelines for the professionals working with the young people and their parents, legal guardians and adults can be suggested.
The aim of the current research is to examine the relationship between the aggressive behaviour, self-esteem and family factors, such as family processes and parenting styles. Furthermore, the differences in behaviour of the juvenile delinquents regarding the age and gender are identified. The empirical research is based on a set of four questionnaires: The Aggression Questionnaire (AQ), Parental Authority Questionnaire for the Mother's and Father's Parenting Style (PAQ), The Adolescent Family Process Measure (AFP) and Rosenberg self-esteem scale (RSES).
The study involved 126 female and 104 male participants. The sample consisting of 230 participants included 129 high school students and 101 university students whose average age was 18,74 years.
The results of the research show that a variable self-esteem has a significant negative correlation with aggressiveness and various forms of aggressive behaviour. The linear aggression analysis indicates that the variable self-esteem in the sample can considerably predict physical aggressiveness, anger and hostility – aggression in general. The analysis of the relationship between aggressiveness and parenting style indicates that mother’s permissive and authoritarian parenting styles statistically significantly predict child’s aggressiveness. On the contrary, authoritative parenting style proves to be the most suitable style in predicting positive behaviour outcomes. Furthermore, there are considerable relationships between aggressiveness and variables referring to family processes. The research shows that the variable conflict is positively related to all forms of aggressive behaviour on the aggression scale. The other variables related to family processes (intimate communication, communication, acceptance) are not significantly related to any form of aggression. However, according to the research, there is a significant gender difference in physical aggression since men tend to be more physically aggressive than women are. Nevertheless, the differences in physical aggression between high school students and university students were not identified.
Since all the potential factors that may lead to aggressive behaviour (personal characteristics, environment factors etc.) were not controlled the limitation of the study refers to the statistical and psychometrical level and to the subject matter. Furthermore, the current study is based on the self-evaluation of the participants, which reduces the objectivity of the results. As aggressive behaviour among elementary and high school students causes more and more difficulties, the strength of the study refers to the importance of researching aggression among youth.|
