Relations between co-rumination, adjustment, and peer relationsPearson correlations computed between co-rumination and adjustment variables are presented in Table 2 (along with correlations among all other coping variables). As expected, co-rumination was significantly and positively correlated with self-reported internalizing symptoms; however, it was not significantly associated with teacher-reported anxious/depressed symptoms. Co-ruminationwas also significantly and directly associated with self-reported externalizing problems, but again not with teacher reports of similar behaviors. Teacher-rated social acceptancewas negatively related to co-rumination as well as both teacher and youth reports of internalizing (not externalizing) problems. Number of friends was not significantlyassociated with internalizing or externalizing behaviors, but was negatively associated with co-rumination. Providing some evidence of convergent validity across reporters, self-reported number of friends was positively associated with teacher reports of social acceptance.
