Adaptive behavior is defined as the degree to which individuals are able to function and maintain themselves independently, and meet the culturally imposed demands of personal an social responsibility. In 1969, the American Association on Mental Deficiency sponsored the development of the Adaptive Behavior Scale to provide a comprehensive assessment of adaptive behavior. This scale was designed to be used in conjunction with intelligence tests for the diagnosis and placement of retarded school age children. The Public School Version of the scale was published in 1974. This report summarizes the research on the Public School Version which was conducted subsequent to its publication. This supplemental information includes reports of additional studies of the validity of the scale, information on domain score reliabilities, and the relationship of IQ to domain scores. In order to assist users in the application of the scale to decision making and to the development of individual education plans, this supplement also provides information about the dimensionality of the scale and samples of Adaptive Behavior profiles which can be prepared to aid in interpreting the results. The author concludes that the scale, as part of a comprehensive case study, can provide invaluable information for improving adaptive behavior, and for assessing intellectual functioning. (Author/BW)
