Associations between attachment security, assessed as a secure base script (SBS), and teachers' social competence ratings were examined in two samples (one from the Midwest region and the other from the Southern region of the United States). Consistent with previous reports, significant associations between domains were obtained in both samples and after combining the two samples, r = .33, p < .001. The associations remained significant when child sex, age, and verbal intelligence were controlled. Findings are discussed with reference to relations between SBS scores and the covariates. Regarding sex differences, an existing literature suggests that girls, compared with boys, may be advantaged with respect to skills that could support higher scores on the task used to assess secure base scripts. In both samples, teachers rated girls as somewhat higher on scales of social competence and controlling for sex reduced the magnitude of associations between SBS and social competence, but the results remained significant in all tests.
