The aim of this graduate thesis was to determine the role of strenghts and individual resilience in explaining anxiety symptoms in high school students in Zagreb city. In this thesis strenghts and individual resilience are operationalized through self-image indicators, self¬efficiency and self- awareness. 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 total sample consists of 719 participants: 295 students from III. Gymnasium, 176 students from Vladimir Prelog High School, 137 students from Geodetic School and 111 students from Carpentry School (N=111). Intensity of experiencing symptoms of anxiety was measured with Depression Anxiety Stress Scales (DASS) (Lovibond and Lovibond, 1995). Self-efficiency and self-awareness were measured with Resilience and Youth Development Module iz California Healthy Kids Survey (Hanson and co., 2007). The results have shown that every 10th high school student which participated in this research has shown serious symptoms of anxiety. Self-image is mainly positive. There are significant gender differences in a way that girls show higher level of anxiety symptoms (especially in categories of serious and very serious symptom levels) and lower level of self-image. Age differences was not distinguished in showing those symptoms. The research has shown that there is a significant negative correlation between anxiety symptoms and level of self-image
