On the other hand buy eriacta 100mg with mastercard, a lack of age differences in disease presentation is unlikely to be reported or published and this could overem- phasize age differences in clinical pain presentation cheap eriacta 100 mg with amex. Studies of clinical pain have usually defined adult groups as being either young or old and there has been little recognition of finer nuances in life stage (e. Nonetheless, a consensus view would be that there are clinically significant changes in the pain experience over the adult life span and that such changes are most obvious in late middle age and the very old age cohorts. PAIN OVER THE LIFE SPAN 131 Psychosocial Influences on the Experience and Expression of Pain Over the Adult Life Span Pain is a complex perceptual experience that combines sensory, affective, and cognitive dimensions. The context in which noxious input is processed, the cognitive beliefs of the individual, and the meanings attributed to pain symptoms are known to be important factors in shaping the overall pain ex- perience. A number of recent studies have examined psychological compo- nents of pain over the adult life span, and there is now clear evidence for some important age differences in cognitive beliefs and coping mechanisms. It has been suggested that older adults perceive pain as something to be expected and just a normal companion of advancing age (Hofland, 1992). A number of empirical studies provide clear support for this view (Harkins et al. Stoller (1993) examined causal attributions in 667 community dwell- ing adults aged 65 plus and found that 43% of the sample attributed joint or muscle pain to the normal aging process. Conversely, in a sample of 396 adults only 21% of the elderly aged 60-plus attributed aching to a specific disease, whereas 36% of young adults aged 20–39 perceived this symptom as a warning sign of disease (Leventhal & Prohaska, 1986; Prohaska, Leven- thal, Leventhal, & Keller, 1985). Under such circumstances older adults may be more likely to interpret pain as a sign of serious illness and seek more rapid medical treatment than their young counterparts (Stoller, 1993; Leventhal, Leventhal, Schaefer, & Easterling, 1993). There are also a number of studies that demonstrate that mild pain symptoms do not affect self-rated percep- tions of health in older adults, but do so in the young (Ebrahim, Brittis, & Wu, 1991; Mangione et al. On the basis of these findings, it is clear that older adults underreport pain as a symptom of illness. Seniors are very aware of the increasing prevalence of disease with advancing age, and this is thought to contribute to the widespread misattribution of pain symp- toms. However, attributing mild aches and pains to the normal aging proc- ess greatly reduces the importance of this symptom and alters the funda- mental meaning of pain itself. Other types of pain beliefs and attitudes have also started to attract in- creasing attention from the pain research community. Gagliese and Mel- zack (1997b) reported a lack of age differences in both pain-free individuals and chronic pain patients when using the pain beliefs questionnaire (Wil- liams & Thorn, 1989). This instrument monitors beliefs about psychological influences over pain (i. Re- gardless of age, patients with chronic pain were more likely to endorse psy- 132 GIBSON AND CHAMBERS chological beliefs than organic causes of pain. In contrast, others have noted that chronic pain patients show significant age differences in most of the beliefs as assessed by the cognitive risks profile (Cook, DeGood, & Chastain, 1999). Older adults (60–90) were found to have a lower cognitive risk of helplessness, self-blame, and absence of emotional support, but an increased desire for a medical treatment breakthrough and a greater denial of pain-related mood disturbance. In a recent study, the locus of control scale was used to examine cognitive factors and the experience of pain and suffering in older adults (Gibson & Helme, 2000). Chronic pain patients aged over 80 years were shown to have a greater belief in pain severity being controlled by factors of chance or fate (Gibson & Helme, 2000). This con- trasts with younger pain patients, who endorse their own behaviors and ac- tions as a strongest determinant of pain severity. In agreement with previ- ous studies (see Melding, 1995, for review), a belief in chance factors was also shown to be associated with increased pain, depression, functional im- pact, and choice of maladaptive coping strategies. Finally, using a newly de- veloped psychometric measure of pain attitudes, Yong, Gibson, Horne, and Helme (2001) found that older persons living in the community exhibited a greater belief in the need for stoic reticence and an increased cautious re- luctance and self-doubt when making a report of pain. These findings are in agreement with early psychophysical studies that show that older persons adopt a more stringent response criterion for the threshold report of pain and are less willing to label a sensation as painful (Clark & Mehl, 1971; Harkins & Chapman, 1976, 1977). The finding is also consistent with other recent studies of stoic attitudes in older pain patients (Klinger & Spaulding, 1998; Machin & Williams, 1998; Morley, Doyle, & Beese, 2000) and provides strong empirical support for the widely held view that older cohorts are generally more stoic in response to pain. Another potentially important psychological influence relates to possi- ble age differences in self-efficacy and the use of pain coping strategies. Self- efficacy in being able to use coping strategies to effectively reduce the se- verity of pain does not appear to change between early adulthood and older age (Corran et al. These findings would seem to challenge the commonly held view that older persons have less self-efficacy and instead show a stability and resilience in beliefs of personal competence across the major portion of the adult life span.
