This dataset, ADHD_df, is a data frame containing ADHD symptom ratings for 355 children aged 6 to 8 years from the Children's Attention Project (CAP) cohort (Silk et al. 2019). The sample consists of 146 children diagnosed with ADHD and 209 without a diagnosis. Symptoms were assessed through structured interviews with parents using the NIMH Diagnostic Interview Schedule for Children IV (DISC-IV) (Shaffer et al. 2000). The checklist includes 18 items: 9 Inattentive (I) and 9 Hyperactive/Impulsive (HI). Each symptom item is binary coded (1 = present, 0 = absent), providing a comprehensive assessment of ADHD symptomatology in young children.
