Jenny Hope in the UK Daily Mail:

Children struggle with maths and making friends when their parents divorce, a study has found.

They often fall behind classmates whose parents stay married, suffering from anxiety, loneliness and feeling sad – and may never catch up academically.

Contrary to some previous research, children through primary school did not show any negative effects before the parents decided to split, the U.S. study found.

But as soon as the divorce process started, the children suffered a range of problems that persisted, a report in the American Sociological Review said.

The five-year study compared emotional and academic development of children of divorce with those whose parents stayed together, by following 3,585 children from around the age of four.
