In the modern welfare state, foster homes carry important social values. On the one hand, they provide protection and supervision for children and adolescents who have been rejected by their natural parents, while on the other, they enhance stability in families that are unable to cope with the role of parenthood.Despite the benefit of foster homes, they are limited in scope and lack professional appreciation (Rimmerman et al.,1985). There are several reasons for the limited use, such as public image as less rewarding (Lakin et al., 1993), parental refusal to place the child in a competitive family, and the lack of foster families willing to serve as foster homes (Rimmerman et al., 1985).Policy-makers are concerned about the quality and stability of foster homes for children, adolescents and young adults with mental retardation (Lakin et al., 1993;Rimmerman et al., 1985).
