The authors discuss the concepts of rehabilitation, and how the meaning of rehabilitation has developed into a more complex term. Topics they address and relate to rehabilitation include: policy indicators; context indicators; program indicators; indicators of the volume of activities; cost indicators; process indicators; impact indicators; outcome indicators; and satisfaction indicators. The authors contend that evaluation of the impact of a rehabilitation program should measure the cultural and strategic changes wrought by the program in the context within which it functioned. They explain this evaluation is important because it enables one to understand the degree of integration and relevance of a rehabilitation experience within the whole health and social context in which it operated.
