Friendships and sibling bonds are often the most enduring relationship
s in a person's life. This study examined what makes each relationship
close and how gender and type of relationship affect the ways in whic
h closeness is manifested. Contrary to previous research on American s
tudents, respondents in the present study did not indicate that they w
ere closer to their friends than their siblings. Rather, closeness eme
rged as a function of similarity in friendships and as a function of d
ependability in sibling dyads. Similarly, women and men reported that
their relationships were equally close; however, closeness was manifes
ted differently for each.
