When it comes to preventing suicide, a lot of emphasis is placed on communication. It's important to talk, say the experts, because it stops the situation from building up to the point where a person believes that ending their life is the only choice they have left.
Now, a new study has revealed just how important talking therapy can be in the prevention of suicide.
Five years after the course of treatment ended, there were 26% fewer suicides among those who had undergone therapy compared with those who had not.
Study leader Dr Annette Erlangsen, from Johns Hopkins Bloomberg School of Public Health in the US, said: "We know that people who have attempted suicide are a high-risk population and that we need to help them. However, we did not know what would be effective in terms of treatment.
"Now we have evidence that psychosocial treatment - which provides support, not medication - is able to prevent suicide in a group at high risk of dying by suicide."
The researchers analysed Danish health data on more than 65,000 people who attempted suicide between January 1 1992 and December 31 2010.
Of that group, 5,678 individuals received psychosocial therapy at one of eight suicide prevention clinics in Denmark.
Their outcomes were compared with those of 17,304 people who had attempted suicide but not received therapy.
The findings are published online in the journal The Lancet Psychiatry.
The therapy itself varied depending on the individual needs of the patient, said the researchers.
It was not possible to point to an "active ingredient" that protected against suicide. However, all the treatments offered a "safe and confidential" place to talk.
Co-author Dr Elizabeth Stuart, also from Johns Hopkins University, said: "Our findings provide a solid basis for recommending that this type of therapy be considered for populations at risk for suicide."
