Självkänsla och familjestöd hos ungdomar med olika aggressionsroll : en representativ studie bland högstadieelever i Österbotten

Objektive: To examine differences in the degree of self-esteem and family support among adolescents involved in different aggression roles from Ostrobothnia in Finland and to examine the relation between aggression role, family support and self-esteem. Method: A sample of 3512 adolescents in school at grades 7 and 9 from Ostrobothnia was considered for this study. The sample consisted of 1741 boys and 1771 girls with the mean age of 14.3 years and SD of 1.10 years. Aggression was measured with the Mini Direct Indirect Aggression inventory (Mini-DIA) by Österman and Björkqvist (2008), self-esteem was measured with the Rosenberg Self-Esteem Scale (RSES) by Rosenberg (1965) and family support was measured with the family support part from the Multidimensional Scale of Perceived Social Support (PSSS) by Zimet, Dahlem, Zimet and Farley (1988). Chi-square test, multivariate analysis and regression analyses were carried out. Results: The boys reported higher self-esteem and received higher family support than girls. The adolescents who were involved in aggression as victims or perpetrators reported lower self-esteem and family support than adolescents who were not involved in aggression. The regression analyses showed that family support and aggression role had significant effects on the adolescents’ self-esteem in both boys and girls. There was also an interaction effect between family support and aggression role for girls, so that the difference in self-esteem between perpetrator-victims and control group for example was higher for girls with low family support than for girls with high family support.
