This study aims to reveal the relationship between the self-perception of five-six-year-old children and the social impact, social preference and various conditions in peer relationships (prosocial behaviour, aggression, asocial behaviour, exclusion, fear-anxiety, hyperactivity and victimisation). Two models are the basis of the objectives for this study. The first is to determine the predictor effect of social impact, social preference and various conditions in peer relationships on the self-perception of kindergarten children (Model 1). The second is to determine the effect of the self-perception of kindergarten children on social impact, social preference and various conditions in peer relationships (Model 2). In the research, which investigates the relationship between self-perception and social impact, social preference and peer relationships on the basis of two different models, the obtained results supported both models to a significant extent (except for the social impact). The results obtained supported Model 2 applied in the research. (Contains 3 tables.)
