This overview of research on relations between siblings with and without di
sabilities addresses four aspects: (1) the role relationships between sibli
ngs, (2) the amount of contact between siblings, (3) qualitative aspects of
this contact, and (4) type of play behavior. Research shows that a charact
eristic feature of the relationship between siblings with and without disab
ilities is a greater role asymmetry compared with pairs of nondisabled sibl
ings: Regardless of birth order, the nondisabled sibling adopts a dominant
position. Contact between siblings is generally not restricted, and sibling
relations are generally rated positively by both nondisabled siblings and
parents. Play behavior reveals that nondisabled siblings try to compensate
the differences in play level and thus establish the necessary precondition
s for playing together.
Research has singled out three factors that could impact on relations betwe
en siblings with and without disability: (1) differential attention paid to
siblings by parents, (2) the transfer of childcare responsibilities to the
nondisabled sibling, and (3) the type of disability. The state of research
on the impact these three factors exert on sibling relations is reported.
Finally, conclusions are drawn for providing psychosocial support to famili
es with disabled children.
