Baseline: CATSS-9/12 study (N = screen-positive in A-TAC for “proxy” diagnosis); Follow-up: Five subcategories of Antisocial behavior in the clinical follow-up study, CATSS-15/DOGSS.
A. NDP defined as ASD and/or ADHD and/or LD and/or TD and/or DCD, with a possible overlap of other mental health problems. NDP screen-positive: n = 198.
B. Other mental health problems defined as OCD and/or ODD and/or CD and/or ED, with no NDP overlap. Screen-positive for other mental health problems: n = 49.
* Questions included in the SDQ Conduct Problems Scale: 1. Often has temper tantrums or hot tempers; 2. Generally obedient, usually does what told (reversed question); 3. Often fights with other children or bullies them; 4. Often lies or cheats; 5. Steals from home, school or elsewhere
