Not only adults suffer from affective disorders also children and adolescents can be affected by depressive moods. Depressive states and their its characteristics are closely connected with problematic social behaviour. Moreover, the extraordinarily sensitive phases of childhood and adolescence have enormous effects on the development of human emotions and social behaviour. In order to provide adequate prevention and intervention measures, research projects should specifically focus on these age groups. The present study tries to examine the correlation between symptoms of depression and social behaviour in 683 Styrian students of the seventh grade. The students were on average 13 years old and attended either urban or rural schools. In addition to gender differences and the influence of the school location, the study also compared the two Austrian school-types Allgemeinbildende Höhere Schule (AHS) and Neue Mittelschule (NMS). In this regard, aspects of social behaviour - particularly aggressive and prosocial behaviour - and the level of depressiveness was determined by means oft wo questionnaires: DTK: Depressionstest für Kinder (Rossmann, 2005), and FEPAA: Fragebogen zur Erfassung von Empathie, Prosozialität, Aggressionsbereitschaft und aggressivem Verhalten (Lukesch, 2006). Product-moment correlations revealed significant connections between inadequate social skills and symptoms of depression: those students who described themselves as more depressed or agitated, reported less prosocial behaviour and at the same time more propensity to violence and aggression. The results also indicate, that girls tend to identify themselves as being more depressed, more tired, more prosocial and in comparison to boys less agitated and aggressive. Futhermore the survey ascertained higher mean scores of NMS-schoolers in depression as well as aggression scales.
