Note: Reported Ns reflect the number of participants with valid scores for the given measure. Sex was dummy coded as female = 0 and male = 1. Maternal education was coded on an ordinal scale where high school diploma = 0, college degree = 1, and post-graduate degree = 2. Lastly, due to small cell sizes for specific racial/ethnic groups, race/ethnicity was collapsed and dummy coded as Non-White = 0 and White = 1. Pubertal stage was assessed via self-report with the Pubertal Development Scale.⁴¹ SCARED = Screen for Child Anxiety Related Emotional Disorders. AX-CPT = AX Continuous Performance Test.
