The basic aim of this paper is to gain insight into the relationship between socialemotional competences and depressive symptoms among adolescents in Zagreb. The specific objectives of this research are to understand the differences in the occurrence of depressive symptomatology and the level of social-emotional competences with respect to some demographic characteristics of adolescents (gender and age) and to establish the level of connection between the level of social-emotional competence and the intensity of the presence of depressive symptomatology in adolescents. The survey was conducted in the period from October 2017 to November 2017 on a sample of 719 participants in four high schools in the city of Zagreb, III. gymnasium (295 participants), Vladimir Prelog High School (176 participants), Geodetic School (137 participants) and Drvodjelja School (111 participants). The survey was conducted in the framework of the project "The positive development of adolescents from City of Zagreb: state of the art" in the Department of Behavioural Disorders, on the Faculty of Education and Rehabilitation Sciences. For the purposes of this project, an instrument has been created consisting of several different scales and additional questions which collected socio-demographic data on participants in research. In order to gain the information needed to accomplish the objective, these scales from the whole research battery were taken into account: (1) General information on the research participants (created for the purpose of this project), (2) Depression Anxiety Stress Scale- 21 (Lovibond and Lovibond, 1995) and (3) Emotional Skills and Competence Questionnaire (ESCQ; Takšić, 1998). The paper-pencil method was used in the research and participation in the research was anonymous, as well as in the line with other relevant ethical principles in the field. The results showed that there is a statistically significant difference in the prevalence of depressive symptomatology with respect to the gender and that the symptoms of depression are more prevalent in females. Furthermore, there was no statistically significant difference in the prevalence of depressive symptoms with respect to the age of the participants. Also, the results show that there is no statistically significant difference in the level of social-emotional competences with respect to age and gender. In terms of correlations, the obtained results showed a statistically significant low negative correlation between the level of socioemotional competences and the symptoms of depression.
