The P.E.P. Report 1969-1973 focuses on the various findings and activities of the Program Evaluation Project. This chapter of the report discusses the basic goal attainment scaling procedures. Goal attainment scaling is a methodology for developing personalized, multivariable, scaled descriptions which can be used for either therapy objective-setting or outcome measurement purposes. Originally developed as an assessment approach for individual clients in a community mental health milieu, goal attainment scaling has since been applied to goal setting for both individuals and organizations across the whole spectrum of human services. This chapter begins with an overview of the core of the goal attainment scaling methodology. The second section discusses the characteristics of utilizing the goal attainment followup guide for assessment purposes. The final section briefly outlines some of the major possibilities which have been implemented or suggested for varying the basic goal attainment scaling format while retaining the basic attainment scaling approach.
