This document is one of three monographs resulting from a three-year study of adult counseling programs and practices in the United States. The first section of this monograph describes issues and potential problems associated with four frequently-experienced adult life transitions, i.e., divorce, midlife career change, preretirement planning, and leisure. For each area, three field-tested activities that counselors can adopt or adapt for use in their work settings are included. The second section provides an overview of adult development and adult counseling. Generalizations are presented regarding both the adult experience and appropriate adult counseling behaviors. For each concept, implications for the adult counseling profession are included. A brief summation of adult counseling is followed by extensive resource lists for the four selected life transitions and for the adult experience in general to offer more in-depth reading and practical counseling materials.
