2.2. Measures
The ABCD study used the Kiddie Schedule for Affective Disorders and Schizophrenia- Lifetime Version (Kaufman et al., 1997) to assess mental health diagnoses and symptoms in children. The K-SADS-PL is a highly reliable semi-structured interview that assesses the manifestation of past and present psychopathological disorders in children, according to the Diagnostic and Statistical Manual for Mental Disorders 5th edition (DSM 5) criteria. These interviews were administered both with the parent and the child, and a total score was calculated. Of interest to this study were the syndromes relating to mania/hypomania, depression, and anxiety.
