Proven to work

Triple P is one of the few parenting programmes in the world that has been scientifically proven to work. It has been rigorously tested and evaluated in more than 150 international clinical trials and studies. Here is a selection of some of the key findings:

  • Triple P reduces problem behaviour in children and improves parents’ well being and parenting skills.
  • In communities where Triple P is widely available, children have fewer behavioural and emotional problems.
  • Parents using Triple P say they are less stressed, less depressed and don’t use harsh discipline.
  • Triple P has been shown to cut rates of child abuse, reduce foster care placements and decrease hospitalisations from child abuse injuries.
  • Parents of children with Autism Spectrum Disorders using Stepping Stones Triple P report they are more satisfied as parents, their children’s behaviour has improved and their relationship with their partner is better.
  • UK parents who watched a reality television series (Driving Mum and Dad Mad) which showed other parents using Triple P, felt more confident in their parenting, less angry and less depressed than before watching the series.
  • Triple P reduced disruptive child behaviour problems in Chinese families living in Hong Kong.
  • The cost of offering Triple P throughout a community would be recovered in a single year if it brought about a (modest) 10 percent reduction in cases of child abuse and neglect.

Additionally, Triple P has been tested and shown to be effective in many culturally and ethnically diverse populations around the world. Here are some of the results:
