Given the limited sample sizes of both Dutch subsamples, only the strongest correlations were entered in the regression analyses up to a maximum of 5. Collinearity proved not to be a problem. However, to limit overlap between constructs, if both child and parent report on the same SDQ scale were correlated, the strongest one was entered. In both Dutch groups, if both a behavior problem scale and a DBD diagnosis or both a hyperactivity scale and an ADHD diagnosis were correlated, the strongest one was entered.
1. If the analyses were run excluding the psychiatric diagnoses ADHD en DBD, only behavior problems entered the model.
2. Running the regression analyses without the psychiatric diagnoses ADHD and DBD produced the same model.
3. The regression analyses including the psychiatric diagnoses ADHD and DBD produced the same model but in a smaller sample.
4. ADHD, parent report behavioral problems, status offenses, reactive aggression, sensation seeking and proactive aggression were entered in the model.
5. Parent report emotional problems, parent report behavioral problems, proactive aggression, ADHD en status offenses were entered in the model.
6. Sensation seeking, parent report behavioral problems, substance use, parent report poor relationship with peers and child report hyperactivity were entered.
