This study of 91 dyads investigated concurrent and prospective bidirectional
associations between friendship quality and psychosocial adjustment in young
adolescents, using multiple-group structural equation modeling to detect gender
differences. Friend reports ofboth positive (social support) and negative features of
friendship, self-reports of two adjustment variables (internalizing problems and
externalizing problems), and self-reports of three dimensions of self-esteem (global selfworth,
behavioral conduct esteem, and close friendship esteem) were examined at two
time periods approximately one year apart. Principal findings were that grade 6
friendship negativity was inversely associated with grade 7 self-esteem, and positively
associated with grade 7 internalizing problems and externalizing problems, in the boys'
model but not girls' model. Chi-square difference testing confirmed a significant
difference between these paths in the girls' model and these paths in the boys' model.
