The study deals with the relationship between antisocial behavior in early adolescence and family environment. Sample consisted of 2,856 adolescents (53%

girls, mean age 13.5 years, SD = 1.1) from urban areas in the Czech Republic. The Social and Health Assessment (SAHA), a school survey, was used to measure sociodemographic characteristics of the family, parent-child interactions, and antisocial behavior. K-means cluster analysis on the items of Antisocial Behavior Scale was used to identify types of adolescents differentiated on the basis of antisocial behavior. Four major clusters of adolescents were identified. Subsequently, adolescents from different clusters were compared on sociodemographic variables (Pearson’s chi-square) and aspects of upbringing (analysis of variance [ANOVA]). While there were no substantial differences between adolescents from the different clusters in sociodemographic characteristics of their family (parental education, parents employment, family structure), there were significant differences in aspects of upbringing (consistence, involvement, control, warmth) between adolescents from clusters differentiated by antisocial behavior.
