Incredible Years Preschool Basic + Advance Parent Training Curriculum

Incredible Years ADVANCE is an add-on component to the Incredible Years Preschool 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 Preschool BASIC intervention, for between nine to 12 additional weekly sessions.

Model description

Incredible Years ADVANCE is part of the Incredible Years series of interventions for children, parents and teachers. It is designed to be offered after either Incredible Years Preschool BASIC (IY Preschool BASIC) or IY School-Age BASIC interventions for families who may need additional support for child-related issues that are particularly entrenched (e.g. oppositional or aggressive behaviours, ADHD, poor social skills, autism spectrum disorders) or parent risk factors, including mental health problems, social isolation, marital conflict, or emotion regulation difficulties.

IY BASIC is delivered by two certified IY facilitators to groups of up to 12 families for 18 to 20 weekly sessions. During these sessions, parents learn strategies for interacting positively with their child and discouraging challenging behaviour.

Incredible Years ADVANCE adds nine to 12 sessions, each lasting 2 to 2.5 hours, to the BASIC intervention. These additional sessions help parents and practitioners consolidate material covered in the BASIC sessions and address topics involving the parents’ behaviour that were not fully explored. These topics include parental communication (both parent to parent and parent to child), emotional self-regulation, problem-solving, and relationship building.

In both the BASIC and ADVANCE models, parent learning is reinforced through discussions, home assignments, video vignettes, role-play practices, and individual goal setting. Video vignettes demonstrate effective communication, emotion regulation, and problem-solving. Structured homework activities between the sessions encourage parents to practise new skills so they can be reviewed during subsequent sessions.

Both the BASIC and ADVANCE models are structured with a manual, but the content allows supports a considerable amount of tailoring based on each family’s individual needs.

Age of child

3 to 6 years old

Target population

Parents of children aged 3 to 6 years diagnosed with oppositional-defiant or conduct disorder

Disclaimer: The information in this section is as offered/supported by the intervention provider.

Why?

Science-based assumption

Young children naturally exhibit challenging and non-compliant behaviours

Challenging child behaviours during preschool and 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 through non-directive play

Strategies for reinforcing positive child behaviour through labelled praise

Strategies discouraging challenging child behaviour through 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 3 to 6 diagnosed with oppositional-defiant or conduct disorder.

How is it delivered?

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 five to eight families.

What happens during the intervention?

  • Parents learn through discussion, home assignments, video vignettes, role-play practices, and individual goal setting.
  • Video vignettes provide models of effective communication, emotion regulation and problem-solving strategies for parents to discuss and apply to their own lives. There are also less effective video models that are catalysts for parents to discuss what they would do differently. Therapists use a collaborative process to encourage discussion in which parents self-reflect and develop parent principles that help them generalise the material presented to their own parenting situations.
  • Role-play practice provides opportunities for therapists to help individualise scenarios to the parents’ own situations and then to practise skills.
  • Practices learned during the sessions are then reinforced through ‘homework’ that parents complete and discuss the following sessions. While the intervention is structured and has a manual and required material to cover, the model is also built on the principle of tailoring the topics, activities, and skills to the individual families in the group.

Who can deliver it?

Two facilitators with experience in a helping profession, trained in the Incredible Years model.

What are the training requirements?

Practitioners have 18 hours of intervention training for the Incredible Years BASIC intervention plus 16 hours of intervention 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 and advanced qualification in psychology or social work), with two to three years of intervention training.

What are the systems for maintaining fidelity?

  • 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 Preschool BASIC + ADVANCE Parent Training Curriculum’s most rigorous evidence comes from two RCTS conducted in the United States which are consistent with Foundations’ Level 3 evidence strength threshold. Evidence from at least one level 3 study, along with evidence from other studies rated 2 or better qualifies Incredible Years Preschool BASIC + ADVANCE for a 3+ rating.

Both Incredible Years Preschool BASIC + ADVANCE’s studies identified statistically significant improvements in child behaviour in comparison to children whose parents did not receive the intervention. One study also observed improvements favouring IY Preschool BASIC + ADVANCE children’s interaction with their peers. However, neither study compared the ‘value added’ of IY Preschool BASIC plus ADVANCE to IY BASIC without the ADVANCE components.

IY Preschool BASIC + ADVANCE does have ‘value added’ evidence from a US study consistent Foundations’ L2 evidence strength threshold. This study observed IY Preschool BASIC + ADVANCE was superior to IY BASIC in improving children’s social problem-solving skills and their parents’ problem-solving and communication skills.

Incredible Years BASIC + ADVANCE can be described as evidence-based: it has evidence from at least one rigorously conducted RCT or QED demonstrating a statistically significant positive impact on at least one child outcome.
