Deliberate self harm in adolescents: self report survey in schools in England.
OBJECTIVE
To determine the prevalence of deliberate self harm in adolescents and the factors associated with it.


METHODS
Cross sectional survey using anonymous self report questionnaire.


METHODS
41 schools in England.


METHODS
6020 pupils aged 15 and 16 years.


METHODS
Deliberate self harm.


RESULTS
398 (6.9%) participants reported an act of deliberate self harm in the previous year that met study criteria. Only 12.6% of episodes had resulted in presentation to hospital. Deliberate self harm was more common in females than it was in males (11.2% v 3.2%; odds ratio 3.9, 95% confidence interval 3.1 to 4.9). In females the factors included in a multivariate logistic regression for deliberate self harm were recent self harm by friends, self harm by family members, drug misuse, depression, anxiety, impulsivity, and low self esteem. In males the factors were suicidal behaviour in friends and family members, drug use, and low self esteem.


CONCLUSIONS
Deliberate self harm is common in adolescents, especially females. School based mental health initiatives are needed. These could include approaches aimed at educating school pupils about mental health problems and screening for those at risk.
