The article presents a review of research on the prevalence of emotional and behavioral problems in children and adolescents raised in foster families. Epidemiological data indicate that these problems are significantly more in this group compared to children raised in biological families. Analysis of the results of the study indicates that children and adolescents from foster families are relatively more often observed to have behavioral problems than emotional problems. The article also presents factors that may increase the risk of these problems. They are divided into internal and external, environmental factors. The most common problems are polyetiological in nature. Also, the support given to the child and family should take into account multiple spheres and ways of influence.
