Unidimensional Conceptualizations of Chronic Pain 297
husband provided extra attention, comfort, and the opportu-
nity to avoid an undesirable social obligation. Therefore, her
pain behaviors were rewarded.
Figure 13.1 describes examples of basic operant principles
in chronic pain. The operant learning paradigm does not un-
cover the etiology of pain but focuses primarily on the main-
tenance of pain behaviors and de“ciency in well behaviors.
Adjustment of reinforcement schedules will likely modify
the probability of recurrence of pain behaviors and well
behaviors.
Pain sufferers do not intentionallycommunicate pain to
obtain attention or avoid undesirable activities. It is more
likely to be the result of a gradual process of the shaping of
behavior that neither the sufferer nor her comforter (i.e., hus-
band) recognizes. Thus, a person•s response to life stressors
as well as how others respond can in”uence the experience
of pain in many ways, but are not the causeof the pain
condition.
It is important not to make the mistake of viewing pain
behaviors as being synonymous with malingering.Malinger-
ing involves the patient consciously and purposely faking a
symptom such as pain for some gain, usually “nancial. As
we noted earlier, in the case of pain behaviors, there is no
suggestion of conscious deception but rather the unintended
performance of pain behaviors resulting from environmental
reinforcement contingencies. The patient is typically not
aware that these behaviors are being displayed, nor is he or
she consciously intending to obtain a positive reinforcement
from the behaviors. Contrary to the beliefs of many third-
party payers, there is little support for the contention that out-
right faking of pain for “nancial gain is prevalent (e.g., Craig,
Hill, & McMurtry, 1999).
Social Learning Processes
Social learning has received some attention in acute pain and
in the development and maintenance of chronic pain states.
From this perspective, the acquisition of pain behaviors may
occur by means of observational learningand modeling
processes. That is, people can acquire behavioral responses
that were not previously in their repertoire by the observation
of others.
Children develop attitudes about health and health care,
and the perception and interpretation of symptoms and phys-
iological processes from their parents and social environ-
ment. They learn appropriate and inappropriate responses to
injury and disease and thus may be more or less likely to
ignore or overrespond to symptoms they experience based on
behaviors modeled in childhood. The culturally acquired per-
ception and interpretation of symptoms determines how peo-
ple deal with disease states. The observation of others in pain
is an event that captivates attention. This attention may have
survival value, may help to avoid experiencing more pain,
and may help us to learn what to do about acute pain.
There is ample evidence of the role of social learning from
controlled laboratory pain studies and from some evidence
based on observations of people•s behaviors in naturalistic
and clinical settings. For example, children of chronic pain
patients may make more pain-related responses during stress-
ful times than would children with healthy parents. These
children tend to exhibit greater illness behaviors (e.g., com-
plaining, days absent, visit to school nurse) than children of
healthy parents (Richard, 1988). Models can in”uence the
expression, localization, and methods of coping with pain
(Craig, 1986). Physiological responses may be conditioned
during observation of others in pain (Vaughan & Lanzetta,
1980). Expectancies and actual behavioral responses to noci-
ceptive stimulation are based, at least partially, on prior social
learning history. This may, along with classical conditioning
and operant learning history, contribute to the marked vari-
ability in response to objectively similar degrees of physical
pathology noted by health care providers.
The biomedical, psychogenic, secondary-gain, and behav-
ioral views are unidimensional. Reports of pain are ascribed
toeitherphysicalorpsychological factors. Rather than being
categorical, either somatogenic or psychogenic, both physi-
cal and psychological components may interact to create and
in”uence the experience of pain. Several ef forts have been
made to integrate physical, psychosocial, and behavioral fac-
tors within multidimensional models.
