Abstract

Intervention permeates all social work processes and gives it a characteristic that distinguishes it from other careers or occupations. It is a concept related to the categories of intervention - directly and indirectly- methodology, method, technique, strategy, methodologies, instrumentality, and instrumental devices. It is present from the birth of Social Work as a profession, and despite having its origin in medicine, it has evolved and adjusted to the paradigm shift, to be appointed as a Social Intervention discipline, as a feature. It is the uniqueness of the profession, that sets it apart from other forms of intervention. Evolves from theparadigm shift and disciplinary consolidation. Coexist interventions, traditional, directed by analytical models, functionalist, linear and modern interventions, guided by circular statements, probabilistic integrators. At its core is a redefined and lifted up at the practice concept that integrates democratic proposals for social construction, the ethical-political and ethical technical dimensions and commitment to social development in systematic and progressive process knowledge dialogue, negotiation culture. Evolves with time, and serves as theoretical and methodological axis of Social Work, in convergence with the investigation. Illustrated this with two recent disciplinary fields, family intervention and social therapy.
