Note: SDQ-SR= Strengths and Difficulties Questionnaire Self Report; SDQ-PR= Strengths and Difficulties Questionnaire Parent Report; BRIEF-PR GEC = Parent report Brief Rating Inventory of Executive Function, Global Executive Composite; BRIEF-SR GEC = Self report Brief Rating Inventory of Executive Function, Global Executive Composite. Sample sizes differed by analysis. For the BRIEF-SR-GEC regressions, they were as follows: SDQ-SR Inattention-Hyperactivity (n = 268); SDQ-SR Conduct Problems (n = 268); SDQ-PR Inattention-Hyperactivity (n = 213); SDQ-PR Conduct Problems (n = 213). For the BRIEF-PR-GEC regressions, they were as follows: SDQ-SR Inattention-Hyperactivity (n = 207); SDQ-SR Conduct Problems (n = 207); SDQ-PR Inattention-Hyperactivity (n = 206); SDQ-PR Conduct Problems (n = 206).
