Book excerpt: This book takes a new, critical, and multidisciplinary look at experiences and meanings of social intervention in different social contexts, taking the approaches of social constructionism as a theoretical approach. The volume collects the results of theoretical-practical experiences that social science professionals with critical and constructionist visions linked to social work intervention have carried out in different spaces. It considers the way social work intervention models are built, their foundation, and their application. It provides the findings on tested intervention models built according to the basis of social constructionism in specific social scenarios, providing interesting findings that show intervention alternatives beyond traditional approaches. The social intervention strategies discussed take place in diverse situations, including health recovery and reconstruction in breast cancer, family abandonment issues of institutionalized adolescents, institutional care of refugee families, women caregivers of children with disabilities, men who exercise violence, and more.
