Approximately 15% of children show significant behavioural difficulties. Research at the University of Manchester (UoM) established that delivery of evidence-based parenting information via broadcast TV changed viewers’ parenting behaviour and, in turn, reduced child behavioural problems. This novel delivery method was implemented and internationally disseminated via the Triple P-Positive Parenting Program. These new Triple P materials have reached an estimated 7 million families in 25 countries. This effective delivery method has also informed UK government policy and initiatives by the United Nations Office on Drugs and Crime (UNODC).
