A NATIONAL children's charity is urging youngsters to talk about their "harmful experiences" after a survey revealed that many bottle up their problems.

Fifty per cent of young teens know someone suffering abuse - such as bullying or bad treatment at home - but keep it a secret, an NSPCC survey revealed.

A third of young teens said they would keep a friend's secret as a sign of loyalty while one in four were worried they did not know how to help.

The findings coincide with the latest phase of the charity's FULL STOP campaign, to encourage young people to speak to a trusted adult if they are worried about something.

"Talking to a friend can be a good first step in dealing with problems," said Mary Marsh, chief executive of the NSPCC.

"However, this can place a lot of responsibility upon young shoulders and put problems out of the reach of adults who are in a position to help.

"We need to take the secrets out of the playground so young people can get the support and advice they need."

The campaign is being backed by powerful TV advertisements, to be screened from tomorrow onwards.

In Worcestershire, the NSPCC receives around 100 calls a month from worried children, or someone on their behalf, while 33 secondary schools ordered advice booklets to give to pupils.

The NSPCC is now calling on the Government to ensure every school has a professional peer support scheme - allowing children to discuss problems where an adult can help.

"Every child needs to have someone they can turn to - someone who will listen, take them seriously and provide suitable advice and support," said Ms Marsh.

"Peer support really can provide that bridge between listening and getting a young person the help they need."

Anyone can help the NSPCC ensure children get the support and advice they need by donating, fund-raising or campaigning.
