A review of systems for psychology and psychiatry: adaptive systems, personality psychopathology five (PSY-5), and the DSM-5.

We outline a crisis in clinical description, in which atheoretical categorical descriptors, as in the Diagnostic and Statistical Manual of Mental Disorders (DSM), has turned focus away from the obvious: evolved major adaptive systems. Adaptive systems, at the core of a medical review of systems (ROS), allow models of pathology to be layered over an understanding of systems as they normally function. We argue that clinical psychology and psychiatry would develop more programmatically by incorporating 5 systems evolved for adaptation to the external environment: reality modeling for action, short-term danger detection, long-term cost-benefit projection, resource acquisition, and agenda protection.
