We identified different patterns in young adolescents' experiences with the
ir siblings and their friends and investigated the connections between thes
e relationship patterns and both young adolescents' psychosocial functionin
g and the characteristics of their family and neighborhood contexts. Partic
ipants were 141 families, including mothers, fathers, young adolescents (M
= 11.4 years), and their younger siblings (M = 8.3 years). Cluster analysis
revealed three groups of young adolescents.. (I) high intimacy and involve
ment with sibling, high intimacy with friend but low involvement with frien
ds ('Differentiated'); (2) high intimacy and involvement with friend but no
r sibling ('Incongruent'); and (3) low involvement and intimacy, with both
sibling and friend ('Congruent'). The Congruent pattern was associated with
young adolescents' personal characteristics and their parent-adolescent re
lationship experiences. In contrast, the Incongruent and Differentiated pro
files were linked to contextual factors (i.e., family and neighborhood reso
urces). Findings suggest that individual differences exist in the associati
ons between young adolescents' relationships with siblings and friends.
