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).

Exclusion Criteria
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
The American Psychiatric Association’s manual of mental health diagnoses. DSM-5 (2013, revised as DSM-5-TR in 2022) replaced DSM-IV, and some studies still name the older edition. “Meets DSM criteria for …” means diagnosed by that edition’s diagnostic criteria, usually by a clinician in an interview.

Parents and their children aged 6-12 with DBD who meet inclusion criteria.
Behavioral: Behavioral Parent Training
Two 15-session multi-component cognitive-behavioral group treatments for children with disruptive behavior and their parents (i.e., one program for children aged 6-8 years and their parents and another for children aged 9-12 years and their parents. The programs have a child and parent group that are implemented concurrently.
Changes in child emotional and behavioral problems between baseline, post-treatment, and follow-up
Changes in child emotional and behavioral problems are assessed using the Strengths and Difficulties Questionnaire (SDQ). It asks parents to indicate how true a statement is with regards to their child's emotions or behaviours in the last 6 months: 'not true', 'somewhat true', or 'certainly true'.
Time frame: Baseline (prior to treatment), post-treatment (within 30 days post-intervention completion) and follow-up (1 year post-treatment completion)
Changes in parenting skills between baseline, post-treatment, and follow-up
Parenting skills are assessed using the Alabama Parenting Questionnaire (APQ). Parents indicate how often an item typically occurs in their home: 'never', 'almost never', 'sometimes', 'often', or 'always'. Each answer corresponds to a score: never = 1, almost never = 2, sometimes = 3, often = 4, and always = 5. The APQ has 3 subscales: positive parenting, inconsistent discipline, and poor supervision. Higher scores on the positive parenting subscale means greater positive parenting skills. Higher scores on the inconsistent discipline subscale means greater instances of inconsistent discipline. Higher scores on the poor supervision subscale means greater instances of poor supervision.
Time frame: Baseline (prior to treatment), post-treatment (within 30 days of treatment completion) and follow-up (1 year after treatment completion)
Changes in parenting competencies between baseline, post-treatment, and follow-up
Parenting competencies are assessed using the Parenting Sense of Competence (PSOC). Parents indicate how much they agree with statements: 'strongly disagree', 'disagree', 'slightly disagree', 'slightly agree', 'agree', or 'strongly agree'. Higher scores on the PSOC indicate higher parenting sense of competence with scores ranging from a minimum of 17 and a maximum of 102.
Time frame: Baseline (prior to treatment), post-treatment (within 30 days of treatment completion) and follow-up (1 year after treatment completion)
Changes in child emotional and behavioural challenges between baseline, post-treatment, and follow-up
This will be assessed using the Behavior and Feelings Scale (BFS) which asks parents to indicate how big of a problem a behaviour or feeling has been for a child in the last two weeks from '0 - not a problem' to '4 - a very big problem'.
Time frame: Baseline (prior to treatment), post-treatment (within 30 days of treatment completion) and follow-up (1 year after treatment completion)
Changes in child emotional and behavioural challenges between baseline, post-treatment, and follow up
This will be assessed using the Child Behavior Checklist (CBCL) which asks parents to indicate how relevant the listed challenges are to their child from '0 - not true', '1 - somewhat or sometime true', and '2 - very or often true'.
Time frame: Baseline (prior to treatment), post-treatment (within 30 days of treatment completion) and follow-up (1 year after treatment completion)
Changes in child emotional and behavioural challenges between baseline, post-treatment, and follow up
This will be assessed using the Modified Connors which asks parents to indicate how much a concerning behaviour describes their child from 'not at all', 'just a little', 'pretty much', or 'very much'.
Time frame: Baseline (prior to treatment), post-treatment (within 30 days of treatment completion) and follow-up (1 year after treatment completion)

Plan to share: No — Would need further REB approval to determine whether participant data could be released based on existing consent.
Ran from Sep 2016 to primary completion in Sep 2022, 72 months.
Of 22 interventional studies with no phase under Attention Deficit and Disruptive Behavior Disorders, half reached primary completion within 39 months of starting (the median), counting those still running; a quarter within 22 and three quarters within 68. This study's 72 months is above that.
