Adaptation level, personality theory, and psychopathology.

Adaptation-level (AL) theory represents a quantitative approach to the concept of adjustment and offers an experimental psychological point of departure for a science of personal and social behavior. It is suggested that a personality theory develop from classification of response types specifying relevant aspects of the focal, background, and residual factors. The various psychopathologies may be similarly viewed in terms of specific behavioral excesses or impairments within the framework of AL theory. A proposal for the use of AL theory in regard to personality and psychopathology is outlined and representative studies are cited. (58 ref.)
