This entry regards intervention research as an essential part of social work as a profession and research discipline. A brief history of intervention research reveals that use of intervention research for the betterment of human conditions is contemporary with the genesis of modern social science. Advances in intervention research are attributed to the comprehensive social programs launched during the 1960s in the United States. A contemporary and generic model of intervention research is described. It is argued that it is ethical to use intervention research and unethical not to use it. Assessment of some of the recent advances in policy making and science gives an optimistic picture of the future of intervention research.
