Psychiatric diagnoses were based on evaluations with the Kiddie Schedule for Affective Disorders and Schizophrenia (K-SADS-E; (Orvaschel, 1995)) administered to a parent; parent and teacher Conners' Rating Scale-3rd Edition (Conners, 2008), ADHD Rating Scale (DuPaul et al., 1998) and Strengths and Difficulties Questionnaire (Goodman, 1997); and a clinical review by a child psychiatrist and a neuropsychologist who had to independently agree on the diagnosis. Intelligence was estimated with a reliable and valid three-subtest short form (Block Design, Vocabulary, and Information) of the Wechsler Intelligence Scale for Children, Fourth Edition (Wechsler, 2003).
