« This study, which was designed to explore the usefulness of role theory in the area of sibling relationships, examined shared norms or children’s sibling roles and compared these norms with findings from studies of children’s sibling relationship. » (p. 549)
« The 284 participants (157 women and 127 men) were recruited from large undergraduate classes in several departments. Of the 276 respondents who provided family information, 7% had no siblings, 47% one sibling, 33% two siblings, and 14% three to six siblings; 33% of those respondents had at least one older brother, 39% at least one younger brother, 30% at least one older sister, and 33% at least one younger sister. » (p. 552)

« This study assesses generally shared norms for children’s sibling roles by examining adults’ role expectations for older brother, older sister, younger brother, and younger sister. Subjects listed prescriptions and proscriptions for each sibling in one of 12 two child families with target children designated as 4 and 1,7 and 4, or 10 and 7 years old for each of four sex compositions. Subjects had more, and relatively more positive, role expectations for older siblings than younger siblings. Expectations differed qualitatively for the siblings (e.g. teaching, help, protection, and admiration with younger siblings). As the ages of the target children increased, role expectations for the siblings became more alike in some ways (e.g. affection and aggression) but less alike in others (e.g. respect and annoyance). The sex composition of the pair minimally influenced subjects’ responses; yet sibling roles for same-sex pairs were more differentiated than role for mixed-sex pairs. Subjects’ sibling status did not affect their responses. The study provides a detailed description of children’s sibling roles and supported the prospect of using role theory as a framework for considering sibling relationships. » (p. 549)
