Abstract

The present paper describes a theoretical model for exaggerated pain perception which has been generated from a multidisciplinary team approach to the problem of chronic low-back pain. The model is an attempt to explain how and why some individuals develop a more substantial psychological overlay to their pain problem than do others.

Central to the model is the concept of ‘fear of pain’ which, it is suggested, leads to differing responses in different individuals. The two extreme responses are those of ‘confrontation’ and ‘avoidance’, although most individuals probably exhibit a mixture of the two. The former, it is argued, leads the individual to resume an increasing range of physical and social activities as the organic basis for the pain resolves and, as a consequence, ensures minimal psychological overlay. By contrast, an avoidance strategy is thought to produce a number of physical and psychological consequences which promote the development of the invalid status and the phenomenon of exaggerated pain perception.

The model suggests that the type of strategy adopted (i.e. confrontation or avoidance) is influenced by a number of psychosocial factors.
