My Lords, I thank the House for its indulgence. I apologise, because my internet connection collapsed completely during the speech of the noble Baroness, Lady Brinton, and I missed a great deal of what she said.
Parental divorce or separation is the second most prevalent adverse event during childhood. There is plenty of evidence that most children who experience parental divorce do not develop long-lasting problems. Many studies show that children are remarkably resilient. Long-term studies of children in Romania after Ceausescu’s regime, for example, showed that, provided they were adopted into loving, caring families, they returned to an almost normal existence.
Even so, there are certain times when biology conflicts with resilience—for example, when children are first socialising, with puberty, with adolescence and with certain mental conditions. Nor can we ignore good follow-up studies of all ages which report problems. They confirm that, compared with children who remained in two-parent families, young people who experience parental divorce are at increased risk of a whole host of difficulties. These include depression later in life and may involve poor social values and behaviour, lack of empathy and various psychopathological disorders, substance abuse and academic underachievement.
These children and adolescents are much more vulnerable to various pressures, particularly when one divorced or separated parent deliberately attempts to undermine his or her offspring’s relationship with the other parent. This may not always be deliberate and,
when it is, it may be difficult to prove in court. There are examples where this is clear cut, with substantial evidence of this kind of damaging behaviour.
As the noble Baroness, Lady Meyer, firmly said in her speech, this amendment is unquestionably about child abuse. Research clearly shows that this can have long-term effects on children as they become adults. Moreover, it is possible—although this is more difficult to show in long-term studies—that traits which a child may develop in consequence of this kind of behaviour may be passed on. The child’s own offspring—the grandchildren of the fractured experience—may be affected. There is, incidentally, increasing evidence of a biological mechanism for such inherited behaviour. There is a significant indication that this may be epigenetic—a chemical alteration which influences the way in which the genes function. Evidence is growing that it may be true for one particular set of conditions which are of growing interest in human development.
Autism spectrum disorder—so-called ASD—is a group of neurodevelopmental disorders in which multiple genetic and epigenetic factors definitely play a role. As long ago as 1991, the famous expert, Professor Rutter, pointed out mistaken stereotypes in psychiatric and behavioural genetics. He was decrying the idea that strong effects might mean that environmental influences must be unimportant. In America, Judith Kroll has pointed out that parental behaviour is critical in enhancing or reducing the negative effects on autistic children. This is often a particular problem with one or other, or both parents. Her study is a useful marker to consider.
I want briefly to mention Karey O’Hara’s remarkable follow-up study from Arizona, looking at 240 children over six to eight years. The study showed very clearly quite subtle changes in these children’s relationship with one or the other parent. Mental health problems, drug abuse and risky sexual behaviour were all common. She and her colleagues concluded that children in families with high levels of post-divorce conflict, which could certainly include the sorts of behaviour to which the noble Baroness, Lady Meyer, referred, are an appropriate target group for preventive interventions. We know that these interventions work; they must surely be better than recourse to law. None the less, it is an important kind of child abuse because it can occasionally be hidden and difficult to see.
This is a vital discussion on an important amendment, and I am glad that the noble Baroness, Lady Meyer, has seen fit to introduce it on Report.
