Prof Pilling, who worked on the guidance suggesting classes for parents of children with conduct disorders, said treating the disorder would save money that would otherwise be spent in the criminal justice system.
By any standard that Nice operates, these treatments are clearly cost effective.
If you put in criminal justice costs, these interventions are dominant. It's actually cheaper to provide them than not to provide them, they're saving money.
– Professor Stephen Pilling, director of National Collaborating Centre for Mental Health
The cost of not treating a 10-year-old with a conduct disorder for the next eight years, over the rest of their childhood, are in the £80,000 to £100,000 range.
