The main goal of this graduate thesis is to verify how important and stressful life events cloud certain aspects of individual resilience of adolescents in Zagreb. Problems are related to stressful events with regard to certain aspects of individual resilience to adolescents. This research was conducted in the period from October to November 2017 in Zagreb, within the framework of the scientific project "Positive development of adolescents in Zagreb: analysis of the situation". The research covered a representative population of high school students from 25 schools in the Zagreb area. This graduate thesis is based on a specific sample from a large-scale research to data, data collected in four high schools in Zagreb. The schools included in this sample of 719 participants are: III. Gymnasium (N=295), Vladimir Prelog High School (N=176), Geodetic School (N=137) and Carpentry School (N=111). The survey was conducted groupwise and was anonymous. Along with demographic variables, individual resilience and protective factors are investigated with scale Resilience and Youth Development Module from California Healthy Kids Survey (Hanson et al., 2007). For the purposes of this thesis, three of the six aspects of resilience have been taken: goals and aspirations, empathy and self-efficacy. Significant and stressful life events were examined by the Questionnaire of Lifestyles that was designed for the project Positive Development of Adolescents in Zagreb based on some similar questionnaires. For the purpose of this research, stressful events are divided into two categories: significant life stressful events and everyday stressful events. The research results show that there are statistically significant differences in the examined three aspects of individual resilience with respect to the sex of the participant in a way that girls exhibit a higher level of individual resilience in all three aspects. However, it has been established that there are no statistically significant differences in the examined aspects of individual resistance with respect to the age of participants. Then, in relation to the level of correlation between the frequency of experiencing stressful events and the level of individual resilience with regard to the type of stressful events and the three aspects of individual resistance, the research shows unbalanced results. This graduate thesis confirms that individual resilience is a complex concept that consists of many different aspects, which are also an inexhaustible source of new findings in the area of mental disorders prevention.
