Pregnancy outcomes included measures of growth (i.e., infant birth weight, length & head circumference), and gestational age at birth. When the children were 14 years old, the Teacher Report Form (TRF; Achenbach & Rescorla, 2001) was used to assess teacher-reported child behavior problems. In addition to total scores, problem behaviors are described along several syndrome scales (Achenbach & Rescorla, 2001): Aggressive & Delinquent behavior (Externalizing); Anxious/Depressed, Somatic Complaints, & Withdrawn scales (Internalizing); and Attention, Social, and Thought problems; and DSM-IV-based scales: Conduct Disorder (CD), Oppositional Defiant Disorder (ODD), Affective, Anxiety, Somatic, and ADHD (including inattention and hyperactivity/impulsivity. The DSM-IV oriented scales consist of items that clinicians have judged consistent with DSM-IV diagnostic categories (Achenbach & Rescorla, 2001). In addition, to behavior problems, IQ was assessed via the Wechsler Intelligence Scale for Children – 3rd Edition (WICV-III). Both Verbal IQ and Performance IQ have good concurrent and construct validity with other IQ assessments (Wechsler, 1991). Maternal reports of teen behavior were collected but not included in this analysis because maternal perceptions of teen behavior problems might have influenced maternal self report of prior drinking, thereby exaggerating relations between drinking and outcomes.
