This article presents the results of research carried out among a group of young adults from foster families and their peers from natural families. The main focus of the research was comparing the factors influencing young people's adaptation. Both groups of young adults, from foster families as well as from natural ones, were compared in relation to creating own aims and own paths of development. The changes in the sphere of the evaluation of future events among young adults from foster families are of major importance for social optimization of their life. The result of the research may bear great significance for social prevention, according to which new ways of optimizing the developmental path for people threatened by social exclusion are searched for.
