* Number of K-SADS-PL disorders: Positive diagnostic areas according to parent or clinician (screen interview), and final DSM-IV diagnoses
** Continuous T-scores for the three CBCL/4-18 broad-band scales: total problems, internalizing problems and externalizing problems
^a Internalizing problems = Sum of CBCL subscales I, II, III (withdrawal, anxiety/depression, somatic complaints)
^b Externalizing problems = Sum of CBCL subscales VII, VIII (delinquent behavior, aggressive behavior)
^c One or more diagnostic areas (for the screen interview) or one or more psychiatric disorders (for final diagnoses)
^d Any affective disorder (depressive disorders, dysthymia, mania, hypomania, bipolar disorder) and/or any anxiety disorder (social phobia, agoraphobia, specific phobias, separation anxiety disorder, generalized anxiety disorder, obsessive compulsive disorder, panic disorder, acute stress disorder, posttraumatic stress disorder)
^e Disruptive disorder (oppositional defiant disorder, conduct disorder)
