The present paper emphasizes the role of adaptive behavior assessment in intervention planning. Adaptive behavior and some of the functions commonly served by measures thereof will be defined. Then, attention will be directed to the characteristics required of instruments used for program planning purposes. Four widely used measures will then be reviewed. A systems approach to assessment that integrates various types of instruments for different assessment functions will be proposed, and an example will be described in some detail.Step-by-step procedures to follow in using adaptive behavior assessment information to develop individualized education programs will be presented. Finally, suggestions for future research will be offered.
DEFINING ADAPTIVE BEHAVIORNumerous definitions of adaptive behavior have been offered over the years and will not be reviewed here. The subject has been treated more extensively in other papers in this issue. Grossman (1983) considered adaptive behavior to be the extent to which a person meets "the standards of personal independence and social responsibility expected for age and cultural group" (p. 1, emphasis added). As observed by Coulter and Morrow (1978), the concept of adaptive behavior potentially could include the whole range of human behavior. Operationally, one could define adaptive behavior as the skills/responses assessed by inat UQ Library on July 11, 2015 sed.sagepub.com Downloaded from
