An Integrated Family Intervention for Child Conduct Problems: How a parenting intervention for childhood behavioural problems influences and is influenced by epigenetic variation in children aged 3 to 8 years.

The REAL Treatment project will investigate the inter-play between evidenced-based interventions that improve the child caregiving context, childhood behavioural outcomes, and, changes in DNA methylation of the major neurodevelopmental genes. 400 Children aged 2 to 8 years and their families will be recruited through the Sydney Child Behaviour Research Clinic over a 4 year period to participate in the REAL Treatment Study: A parenting Intervention for Child Conduct Problems. Families and the research team will form a supportive partnership to assess and monitor a child’s behavioural, emotional and neurodevelopmental progress, as well as parenting progress and family environment over the course of a 6 to 10 week tailored, evidenced-based parenting intervention to address child conduct problems. Assessments will be taken prior to and directly after receipt of the intervention as well as at a three month follow-up review assessment. Assessment will cover areas including: Child adjustment and diagnostic status, caregiver/parent adjustment, family environment, engagement with and dose of intervention received, epigenetic assessment (buccal cell collection for methylation assessment) and neurodevelopmental assessment (examining processes of emotional attention and responsiveness to stimuli). Preliminary assessments will also be conducted with a sub-sample of participants who are expected to be on the wait-list for 3 months or more before commencing treatment. A multi-informant assessment method will be applied throughout the research protocol that includes gathering data from: parents/caregivers; clinical interviews; the use of standardized questionnaire and psychometric assessments; coding of observational data of child and family interaction activities; and, teacher/educator reports and completion of questionnaires. We aim to a) confirm an emerging model of how epigenetic regulation of the major neurodevelopmental systems maps onto individual differences in comorbid symptom profiles before and after intervention; b) to examine how this regulation and mapping predicts individual differences in responsiveness of children to intervention that produces standardised and measurable improvements in the child caregiving environment; c) to examine how early intervention alters epigenetic regulation of the major neurodevelopmental systems and REAL (responsiveness, emotional attention and learning) phenomena, thus modifying risk versus protection for future development.
