Parenting classes should be made more available to help families deal with challenging behaviour, research says.
A King's College London study suggests young people displaying antisocial behaviour who do not feel cared about by their parents cost more socially than those who feel well supported.
The study says parenting classes could help families form stronger bonds.
It says early interventions can "improve child outcomes and reduce the financial burden on society".
The researchers assessed data from 174 young people, aged between nine and 17.
Of these, 85 had been rated by their schools as having moderate antisocial behavioural issues, while 89 had been referred by mental health services as having high levels of antisocial behaviour.
The young people (73% of whom were male) were interviewed for about an hour, separately from their parents, and asked how they felt about their parental relationships.
If they trusted their parent to provide emotional support, they were designated as having a secure attachment - but if they dismissed their parent as not there for them, they were designated as having an insecure attachment.
Using statistical software, the researchers examined data about the level of health, educational and social care services the families had accessed, as a result of their child's behaviour, in the previous year.
They took into account the parents' reports of how naughty the child was, as well as the child's own assessment of their behaviour and they also controlled for the child's level of antisocial behaviour recorded at the age of five or six.
The results showed those with secure attachments cost less than those with insecure attachments, whether or not they were in the group displaying moderate antisocial behaviour or high levels.
The study found young people securely attached to their mother cost £6,743, whereas those insecurely attached cost £10,119 - a £3,456 difference.
Differences were more striking for fathers, with securely attached youths costing £1,353, while insecurely attached youths cost £12,625 more at £13,978.
