One in ten 16 year olds in Northern Ireland have self-harmed in the past year, according to new research. Of the 941 young people who were questioned during the 2008 Young Life and Times Survey, a further 14 per cent had thought about harming themselves in the past year but had not done so. This is the first time a representative sample of young people in Northern Ireland has been asked about their attitudes to and experiences of self-harm.
