Résumé:
The Institut national de santé publique du Québec has been mandated to prepare a knowledge synthesis for the Direction générale de la santé publique of the Ministère de la Santé et des Services sociaux on reference points underpinning actions to enhance mental health, on life situations encountered during the passage to adulthood and the resources that can have a positive effect on the mental health, and on the relevant spheres of action to promote mental health in young adults. To do this, a literature review from scientific literature and from grey literature was conducted. This allowed the identification of four reference points: looking at mental health as a concept distinct from mental disorders, focusing on helping each and every person reach their potential by building on their strengths instead of focusing on their problems, addressing the social determinants of mental health and their distribution, and adopting a life-course approach.
