This article is a review of research concerning the friendships of del
inquents and nondelinquents. Contrasting theories and corollary resear
ch have pointed to either the distinctiveness of delinquent friendship
s or to the commonality with normal friendships. On close examination,
with exceptions due to methodological and sample features, the resear
ch has been more supportive of differences in behavioral, cognitive, a
nd affective characteristics of friendships. Greater conflict, poorer
attachment quality, lesser ability to repair relationships, cognitive
distortions, and poorer social-cognitive problem solving characterize
delinquent friendships. There is little support for the superior quali
ty of friendships of delinquents, as some had speculated. A failure to
find differences between delinquents and nondelinquents in certain st
udies may be traced to use of single-index measures of qualitative asp
ects or variations in the sample studied, but this cannot be taken to
mean there are no differences in the population from which the samples
were drawn.
