Clinical social work is a derivative profession, drawing its knowledge and practice base from several theoretical schools. The four primary theoretical schools contributing to social-work philosophy are psychodynamic, humanist, cognitive–behavioral, and postmodern. Acceptance and commitment therapy (ACT), although considered one of the third-wave behavioral approaches, draws from all four theoretical schools of clinical intervention. This entry gives an overview of ACT development, its essential features, empirical base, tenets and techniques, and relevance to the social-work profession.

Formal or institutional social services began in the United States in the late 19th century as a response to problems that were rapidly increasing as a result of modernization. These services were almost entirely private until the Great Depression in the 1930s when the government became involved via provisions of the Social Security Act. Services expanded greatly, beginning in the 1960s when the federal government developed a system wherein services were supported by public funds but provided through contracts with private agencies. This trend has continued and expanded, resulting in a uniquely American system wherein private agencies serve as vehicles for government social service policy.
