Personalizing Psychosocial Intervention for Children With Disruptive Behaviour

Personalizing Psychosocial Intervention for Children With Disruptive Behaviour

This study will develop and test whether personalized profiles of children with Disruptive Behaviour Disorder (DBD) and their parents based on important psychological, emotional, and neuropsychological indicators predict their response to child cognitive behavioral treatment and Behavioral Parent Training (BPT).

To accomplish these goals, the investigators will collect psychological, emotional, and neuropsychological measures before and following cognitive behavioural therapy (CBT) for both children and parents. The investigators will use statistical modeling to determine profiles of parents of children and children aged 6-12 years with DBD based on key domains of mental health, emotion regulation, cognition, and parent-child behaviour, and observe whether these profiles allow the study team to predict which sub-groups of parents and children are most and least likely to benefit from child CBT and Behavioural Parent Training (BPT).
