Level 4 Group Triple P
Level 4 Group Triple P is a targeted-indicated intervention for parents with a child between 0 and 12 years old who have concerns about their child’s behaviour.
Groups of up to 12 parents attend sessions over eight weeks delivered by a single trained and supervised clinical psychologist. These sessions include five two-hour group meetings, as well as three individual telephone consultations lasting 15 to 30 minutes.
Parents learn 17 different strategies for improving their children’s competencies and discouraging unwanted child behaviour. Role play, homework exercises and discussions involving video-taped examples of effective parenting strategies are used to help parents learn methods for dealing with unwanted child behaviour and supporting their child’s emotional needs.
EIF Programme Assessment
Level 4 Group Triple P has evidence of a short-term positive impact on child outcomes from at least one rigorous evaluation.
What does the evidence rating mean?
Level 3 indicates evidence of efficacy. This means the programme 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.
This programme does not receive a rating of 4 as it has not yet replicated its results in another rigorously conducted study, where at least one study indicates long-term impacts, and at least one uses measures independent of study participants.
What does the plus mean?
The plus rating indicates that this programme has evidence from at least one level 3 study, along with evidence from other studies rated 2 or better.
A rating of 1 indicates that a programme has a low cost to set up and deliver, compared with other interventions reviewed by EIF. This is equivalent to an estimated unit cost of less than £100.
According to the best available evidence for this programme's impact, it can achieve the following positive outcomes for children:
Preventing crime, violence and antisocial behaviour
Improved behaviour - based on,
This programme also has evidence of supporting positive outcomes for couples, parents or families that may be relevant to a commissioning decision. Please see About the evidence for more detail.

About the programme
What happens during delivery?
How is it delivered?
- Level 4 Group Triple P is delivered by a Triple P practitioner in five sessions of approximately two hours’ duration to groups of up to 12 families. An additional three sessions (between 15 and 30 minutes each) are delivered to individual families via telephone.
What happens during the intervention?
- Parents learn 17 different strategies for improving their children’s competencies and discouraging unwanted child behaviour.
- Learning is supported through role play exercises, homework exercises and group discussions involving video-taped examples of effective parenting strategies.
What are the implementation requirements?
Who can deliver it?
- The practitioner who delivers this programme is a Triple P practitioner, who can come from a range of professions (eg family support worker) with recommended minimum QCF-4/5 level qualifications.
What are the training requirements?
The practitioner has three days of programme training. This includes one day of pre-accreditation, and a half-day accreditation workshop (accreditation workshops are held over two days; practitioners attend in groups of five). Booster training of practitioners is not required.
How are the practitioners supervised?
- It is recommended that practitioners are supervised by one host-agency supervisor with QCF-7/8 level qualifications, with no required programme training.
What are the systems for maintaining fidelity?
- Accreditation process
- Training manual
- Fidelity monitoring
Is there a licensing requirement?
There is no licence required to run this programme.
How does it work? (Theory of Change)
How does it work?
- Triple P is based on the idea that parents often unintentionally perpetuate unwanted child behaviour through ineffective parenting strategies.
- Triple P helps parents replace ineffective parenting strategies with effective methods for encouraging positive child behaviour.
- In the short term, parents learn more effective strategies for managing their child’s behaviour and the child’s behaviour improves.
- In the longer term, children should have greater self-regulatory skills and self-confidence and do better in school.
- It is also expected that children will be less likely to have behavioural problems and/or engage in antisocial behaviour.
