Vertaling van "they have all had specific training " (Nederlands → Frans) :

They have all had specific training on the issue of suicide and offer different types of counselling in order to meet different expectations: individual meetings, open or closed discussion groups – either self-help groups or groups that are coached by professionals – for children, teenagers and adults.
Ils ont tous reçu une formation spécifique à la problématique suicidaire et proposent une gamme d’accompagnement répondant à différentes attentes possibles: entretiens individuels, groupe de parole ouvert ou fermé, en self help ou animé par des professionnels, pour enfants, adolescents et adultes.

When possible, those who have had the training can share the knowledge they have acquired with the staff of their hospital.
Si c’est possible, ceux qui ont suivi la formation peuvent transmettre les connaissances acquises au personnel de leur hôpital.
