The aim of this article is to present family therapy as an effective and adequate method of treating anxiety disorders in children and adolescents. Considering the significant prevalence of these disorders in the population of patients seeking help from mental health professionals, the development of effective therapeutic methods to work with anxiety in children and adolescents seems to be highly recommended. The first part of the article presents the characteristics of anxiety disorders in children and adolescents. Next, traditional models of conceptualization of children’s anxiety are described. The dominant methods of therapy are shown as well, taking into account the fact that they are insufficiently focused on family factors, which – based on current theoretical concepts and empirical data – should be considered very important in relation to emotional difficulties in children and adolescents. The next part of the article presents research indicating the rationale and even the necessity to involve parents in the treatment of anxiety in their children, as well as therapeutic programs taking into account family interventions. In the summary, there are conclusions, reflections, and proposed directions for further research in the area of family therapy focused on the treatment of anxiety disorders in children and adolescents.
