Abstract
This study was designed from the theoretical perspective of Sullivan who proposed that during preadolescence, a “chum” relationship increases a child's sense of self-worth. Ss were 60 male sixth graders, with an equal number in the chumship and nonchumship groups. Self-concept was measured with the Piers-Harris Children's Self-concept Scale. It was found that children involved in a chum relationship possessed significantly higher self concepts than those without a chum. This finding was accounted for in terms of Sullivan's notion that a chum relationship provides the opportunity for the preadolescent to realize that he shares common thoughts and feelings with his friend. Thus, his own sense of self-worth is consensually validated.
