Almost 20% of 13-year-old girls believe they have symptoms of depression 

A study found 16% of younger teenagers rated themselves as having symptoms consistent with a diagnosis of ‘depression’, but for girls it rose to 18%, versus 14% for boys.

Almost a fifth of 13-year-old girls believe they have symptoms of 'depression',  the ESRI's latest 'Growing Up in Ireland' study has found.

The strength of teens' friendships and conflict with their parents, especially their mothers, are among the reasons given.
