According to Salvador Minuchin’s (1974) theory, it was assumed that inappropriate boundaries (rigid or diffuse) between parents and children make adolescents less competent in difficult social situations, while individuals from families with clear boundaries are more competent in social situations such as intimate contact, social exposition and assertiveness. The modified versions of Analysis of Family Environmental Scale by M. Ryś (2004) and Social Competence Questionnaire by A. Matczak (2001) were used in the study. 345 adolescents from different types of families were examined. The results of the analysis of variance (ANOVA) indicated that there is a connection between family boundaries and interpersonal skills of adolescents.
