ABSTRACT
Presurgical psychological screening represents a new extension of a long line of theory and research concerning the nature and treatment of pain. For many decades it has been recognized that pain is a complex phenomenon, involving “affective, cognitive, and behavioral as well as sensory mechanisms” (Fields, 1991, p. 8). However, there have been a number of quite disparate viewpoints on the processes involved in pain perception and response. This chapter represents a brief review of four major theoretical viewpoints that have had a significant influence on the field of pain management. It is not critical to understand these viewpoints in order to perform PPS. Thus, the reader who wishes to quickly gain knowledge of PPS techniques may skip this chapter and return to it at a later time. However, knowledge of the major theories on pain will help the behavioral health practitioner to develop and refine his or her own conceptualization of pain mechanisms. Further, scientific research can spring from an understanding of pain theories. Finally, the information discussed in this chapter will help the practitioner to communicate with other professionals in the field of pain management.
