highly significantp < 0.001
For boys: Likelihood ratio test comparison between the full model (including age and direct BIS-BAS orientation score) and null model was highly significant ( Χ 2 (21) = 11.22, p < 0.001), with a main effect for the direct BIS-BAS orientation score (estimate ± SE = 0.22 ± 0.06, z = 3.28, p = .001), suggesting that BAS-oriented boys took ~80% of others’ resources.
