lationships between siblings when one child has a disability. Descriptive f
indings are presented that compare and contrast sibling warmth and positivi
ty, engagement, and conflict in sibling pairs with and without a child with
a disability. The social roles assumed by siblings are examined, as are de
velopmental changes in role relationships. Research on the development of t
he sibling relationship in the family context is reviewed, as are findings
concerning the effects of parent differential attention on the quality of t
he sibling relationship, (C) 2001 Wiley-Liss, Inc.
