Friendship requires hard work even for the most able, and the odds are heavily stacked against those with an autism spectrum disorder. Designed for younger children, aged between 2 and 8, this set of activities emphasises foundation skills such as social referencing, regulating behaviour, coversational reciprocity and synchronized actions. This volume is also available as a set with "Relationship Development Intervention with Children, Adolescents and Adults" (ISBN 1-84310-720-1).
