The objective of this chapter is to describe the strategies of intervention that promotes mental health. These strategies have been identified in several quantitative and quality studies that deal with social well-being and psychosocial trauma. These studies belong to researches in the field of social development which were done by a group of researchers in human development formed by gidhum from the Universidad del Norte, Universidad Autónoma de Madrid and the Universidad José Simeón Cañas de El Salvador. The psychosocial intervention strategies found on those studies were the following: 1) reconstruction of the historical memory for the strengthening of self identity; 2) qualification of confrontation strategies; and 3) improvement in the support networks which clearly promote discarding a pathogenic model based on psychological distress and using a saluto-genic approach instead, that focuses on welfare as an indicator of mental health.
