Incredible Years School Age Basic + Advance Parent Training Curriculum

Incredible Years ADVANCE is an add-on component to the Incredible Years School Age BASIC intervention. It is designed to be delivered to families after they have received the BASIC intervention and includes opportunities for the parent and child to attend the intervention together. It is delivered by two IY certified facilitators to groups of five to eight families who have already received the School Age BASIC programme, for between 9 to 12 additional weekly sessions.

Model description

Incredible Years School Age Basic is part of the Incredible Years series of interventions for children, parents, and teachers. IY School Age Basic is specifically for parents with concerns about the behaviour of a child aged between 6 and 12 years.

IY School Age BASIC is suitable for children with attention deficit hyperactivity disorder (ADHD), oppositional defiant disorder (ODD), conduct disorder (CD), or difficulties with peer relationships. It aims to increase the use of effective parenting strategies and ultimately reduce antisocial or criminal behaviour in children who may be at risk.

Incredible Years ADVANCE is an add-on intervention to the Incredible Years Prechool BASIC and School Age BASIC interventions, designed to be delivered to families after completing the BASIC intervention. It is particularly recommended where child risk factors, such as oppositional or aggressive behaviours, ADHD, poor social skills, or autism spectrum disorders, or parent risk factors, such as mental health problems, poor communication skills, social isolation, marital conflict, or emotion regulation difficulties, are present. The intervention aims to support high-risk groups who are likely to progress slower through the curriculum content by enabling parents and practitioners to consolidate and progress on content for which there was no time in the BASIC intervention sessions.

IY School Age BASIC is delivered in 12 to 16 two-hour sessions by a lead and co-practitioner to groups of 8 to 12 parents. When combined with the Advanced Programme, parents attend an additional 10 to 12 sessions depending on the needs of the target group. It can also be delivered individually to families in 12 to 16 sessions lasting 1.5 to 2 hours each.

During the sessions, parents engage in group discussions guided by facilitators, sharing experiences and understanding the rationale behind the strategies. Role-plays allow parents to practise new strategies, tailoring them to specific issues faced at home. Homework encourages parents to implement these strategies with their children, and they return to the group to refine their approach with feedback. Weekly reading assignments offer theoretical and practical guidance, while video vignettes showcase diverse parenting scenarios, helping parents develop effective strategies tailored to their unique family situations.

Age of child

6 to 12 years

Target population

Parents of children aged 6 to 12 years diagnosed with oppositional-defiant or conduct disorder, and who would benefit from more time to progress through content than is possible in the BASIC intervention alone

Why?

Science-based assumption

Challenging child behaviours during primary school increase the risk of behavioural problems in adolescence.

Science-based assumption

Effective parenting helps children to regulate their own behaviour and reduce the risk of child behavioural problems becoming established.
Ineffective parenting strategies can increase the risk of child behavioural problems becoming further entrenched.

Who?

Science-based assumption

Parents dealing with stressful family circumstances or child behaviour that is particularly challenging often benefit from additional parenting support.

How?

Intervention

Parents learn:

Age-appropriate expectations for their child

Strategies for establishing predictable family routines

Strategies for promoting positive parent–child interaction

Strategies for implementing age-appropriate discipline.

What?

Short-term

Parents implement effective parenting strategies in the home

The parent’s confidence and self-efficacy as a parent increases

Parent–child interaction improves.

Medium-term

Children are better able to regulate their behaviour and emotions

Children’s behaviour improves

Behavioural problems are less entrenched.

Long-term

Children are at less risk of antisocial behaviour in adolescence

Children are more likely to engage positively with others.

Who is eligible?

Parents of children aged 6 to 12 years diagnosed with oppositional-defiant or conduct disorder.

How is it delivered?

Incredible Years School Age BASIC is delivered in 12 to 16 sessions of two hours’ duration each by two practitioners, to groups of 8 to 12 parents (5 to 8 families).

Incredible Years ADVANCE is delivered in 9 to 12 additional sessions of 2 to 2.5 hours’ duration each by two practitioners, to groups of 8 to 12 parents (5 to 8 families).

What happens during the intervention?

Group discussion and brainstorm: guided by facilitators, parents discuss new content, share their own experiences, and come to an understanding of the rationale behind the parenting strategies that are presented to them during the intervention.

Role-plays: parents practise strategies in the parent role, and experience the new strategies from the child’s point of view. Role-play is tailored to represent specific issues that families in the group are experiencing at home.

Homework: parents take what they have discussed and practised in the group and try the new strategies at home with their own children. They come back to the group to report on what worked and what did not work, so that they can receive ideas and feedback to refine their practice.

Parent book: parents have a reading assignment each week that provides some theory behind the strategies that they are learning, as well as practical examples of how to implement the new strategies.

Video vignettes: parents watch vignettes of other parents who represent a diverse range of cultures, family circumstances, and child developmental level. From these vignettes, the parents develop principles of effective parenting and think about how they wish to apply these with their own children.

Who can deliver it?

The practitioners who deliver this intervention are two psychologists, mental health counsellors, marriage and family therapists, social workers or similar practitioners.

What are the training requirements?

The practitioners have 18 hours of training for the Incredible Years BASIC intervention plus 16 hours of training for the Incredible Years ADVANCE intervention. Booster training of practitioners is recommended.

How are the practitioners supervised?

It is recommended that practitioners are supervised by one clinical host-agency supervisor, with two to three years of intervention training.

What are the systems for maintaining fidelity?

Intervention fidelity is maintained through the following processes:

  • Training manual
  • Other printed material
  • Other online material
  • Video or DVD training
  • Face-to-face training
  • Fidelity monitoring.

Is there a licensing requirement?

No

Incredible Years School Age BASIC + ADVANCE’s most rigorous evidence comes from a single RCT conducted in the United States consistent with Foundations’ Level 2 evidence strength criteria.

This study identified statistically significant pre/post intervention improvements in parents’ reports of their children’s behaviour and emotional wellbeing. Parents also reported improvements in their disciplinary practices.

Incredible Years School Age BASIC + ADVANCE Parent Training Curriculum has preliminary evidence of improving a child outcome, but we cannot be confident that the programme caused the improvement.
