WHEN she signed up for a self-development course, Rebekah Lawrence hoped it would help her find happiness. Instead, it triggered a psychotic state in which she leapt naked to her death from her office window.

Yesterday, the Deputy State Coroner, Malcolm MacPherson, found her deadly psychosis stemmed from the course she had completed two days earlier, known as The Turning Point.

For Ms Lawrence's family, the finding confirmed what they had believed since she died on December 20, 2005. Her widower, David Booth, said there were ''unqualified people doing damaging things to people's minds'' - with potentially fatal results.

An inquest into Ms Lawrence's death heard there were no legal restrictions for practising under the titles of psychotherapist or counsellor, and therefore no public safeguards.
