Aggression was linked to more negative, r ¯ = .19, 95% CI [.14, .24], and less positive, r ¯ = -.05 [-.08, -.01], friendships. Withdrawal was associated with less positive friendships, r ¯ = -.13 [-.18, -.08], whereas prosocial behavior was related to more positive, r ¯ = .29 [.22, .37], as well as less negative, r ¯ = -.16 [-.20, -.12], friendships. Assertion was related to more positive friendships, r ¯ = .15 [.01, .28].
