Professor Tanya Byron, clinical psychologist and TV presenter, is interviewed by Kirsty Young for Desert Island Discs.

Tanya has spent the last twenty years in clinical practice, helping children, young people and families deal with some of the most difficult parts of life - depression, anxiety, aggression, self harming and drug addiction.

She came to public prominence through her television work, books and advice columns and it would seem that she had the perfect background to cope with life in the spotlight - her father was a successful tv and theatre director and her mother worked variously as a nursing sister and a model.

A highly dramatic family tragedy ignited her interest in what spurs people to behave the way that they do.

She says of her work "I do have a particular desire to enable young people, on the cusp of what could be the most extraordinary life, to live ... and live well."
