This report describes the workshop, sponsored by the Laboratory of Community Psychiatry, Harvard Medical School, that gathered in Cambridge on April 21-23, 1971 to explore the question: Is there a definable discipline of community crisis intervention (CCI) with a discoverable body of techniques which can be systematized, taught, evaluated and refined to help communities achieve positive social change through resolution of the crisis? The immediate objectives of the Workshop were to expand the pooling of knowledge and techniques in the field and to include in its report the first major statement of theory and techniques about CCI. The workshop also stressed that the accumulated knowledge and techniques in community crisis intervention should benefit grass roots, minority and otherwise powerless groups in their quest for self determination. During the conference, the participants focused on methods of intervention for social change and the future of community crisis intervention. Six appendices are also included in the Workshop final report: A-Workshop Participants; B-Workshop Program; C-Participant Evaluation; D-Outline for Case Studies in Community Crisis Intervention; E-Bibliographic Materials; and F-Summary of Findings and Theory from a Case Study in Community Crisis Intervention.
