Child Behavior Checklist (CBCL).

The CBCL/6–18 is a parent-report measure comprised of items scored on a 3-point Likert scale that assesses frequency of behaviors indicative of psychopathology and atypical development in children ages 6 to 18 years (58). Internalizing and externalizing problem raw scores were used as dimensional measures of internalizing and externalizing symptoms. The depressive problems, anxiety problems, attention deficit/hyperactivity problems, oppositional defiant problems, conduct problems, and obsessive-compulsive problems raw scores were analyzed as dimensional measures of disorder-specific symptoms. Raw scores were used for all statistical analyses, allowing us to model change in these metrics over time. T-scores were only used to summarize and illustrate symptoms by SOR group relative to approximate cutoffs for scores in the borderline clinical (65≤t<70) or clinical (t≥70) range.
