Circle of Friends is a recent intervention used to tackle social isolation in childhood. Its aim is to promote social inclusion by establishing a friendship group for an isolated child. Although there is some literature relating to the development and implementation of this approach, there is relatively little evidence regarding its effectiveness. Two evaluation studies of the Circle of Friends approach are discussed in this paper. Both studies involve adaptations of the traditional model. Consideration of these models and an evaluation of their relative effectiveness in promoting social inclusion is made. Implications for educational psychology practice are explored.
