^a Composite scaled score of all internalizing disorders (α = .89) and externalizing disorders (α = .74)

^b Nicotine use was significantly associated with these disorders, and analyses were repeated with nicotine use as a covariate: GAD (r = .37, p = .01), Depressive Disorder (r = .46, p = .003), Dysthymic Disorder (r = .37, p = .03), ADHD-Combined Type; r = .41, p = .007, ADHD-Inattentive Type (r = .31, p = .045), ADHD-Hyperimpulsive Type, r = .38, p = .01).

⁺ indicates significant at Bonferroni corrected α = .004
