Psychopathology and Public Policy

An effective definition of psychopathology would be helpful in distinguishing between normal and abnormal behavior and would provide guidance for important public policy decisions. Overinclusive definitions, such as the capacity/disability formulation, do not provide meaningful direction for defining need or assessing eligibility for insurance or other entitlements. Coping failures due to lack of skill, inadequate preparation, or other factors should be distinguished from those due to dysfunction or disturbance of psychological mechanisms. The capacity/disability formulation encourages confusion between different performance decrements and gives no guidance for appropriate boundaries for psychotherapy.
