In Adolescence and Early Adulthood we carry out long-term research of various aspects of mental and social development in adolescence and in the transition to adulthood. We study how a personality forms, what influence cognitive, emotional and social characteristics have on shaping one’s relationship to oneself, e.g. shaping one’s identity, perception of self, self-evaluation, autonomy, life satisfaction well-being, personal perspective and values, how these factors change and what importance interpersonal relationships have in this process. Our research is longitudinal and cross-sectional, combining quantitative and qualitative research.
