Those who were ill applied the use of social comparisons strategically buy tamsulosin 0.4mg visa, to enhance their own mood if they could order 0.2 mg tamsulosin amex, and particularly to boost their self-esteem (Blalock et al. Sick people also employed higher order social comparisons based on what more abstract groups like “society,” their own sociocultural groups, and the medical profession (as represented by their doctors), ex- pected from someone of their age, sex, stage of illness, and so on (Skev- ington, 1994). Together, categorization and comparisons lead to identification with a group or isolation from it. Pain has often been associated with feelings of isolation (Rose, 1994) and alienation. Addressing the identities of those in pain at a group level could be a more appropriate and cost effective method than individual consultations. This could be brought about through the use of newsletters, meetings, support groups, and trained lay leaders in self-management groups. In a study looking at how sense is made of the causes of chronic pain, Eccleston and colleagues found that pain challenges the identities of patients and health professionals when responsibility and blame are taken away from the sufferer and healer. These findings clearly have interactive implications for the way that patients and health profes- sionals respond to each other (Eccleston, Williams, & Rogers, 1997). The media plays a pivotal role in presenting, reflecting, and reinforcing society’s message about those in pain. A hard-wired model of how migraine is relieved, presented in a well-known analgesic advertisement in Britain, propagates the erroneous image of a pain mechanism that predates the ad- vances made by the gate control theory of pain and makes it harder to man- age the beliefs of those who seek treatment. It perpetuates the view that medication is the only solution to pain, ignoring other important strategies and influences. The reverse side of media influence has been recently illus- trated in an Australian study (Buchbinder, Jolley, & Wyatt, 2001), where a population based multimedia campaign intervention was designed to alter 196 SKEVINGTON AND MASON beliefs about back pain. Studies such as this highlight the power of the media in influencing beliefs about pain and people’s response to it. Level 4: Higher Order Factors Level 4 represents the higher order factors affecting social and psychologi- cal processing that influence the response to pain, such as health culture, history, ideology and politics, quality of life, and economic beliefs about health. For health culture we must ask how particular cultural beliefs foster sickness and wellness in the community. There was a Western cultural tra- dition of prescribing extended bed rest for all low back pain sufferers until the results of Deyo’s seminal study (Deyo, Diehl, & Rosenthal, 1986) showed how this recommendation was contraindicated for those without malig- nancy or herniated disc and indeed, could be iatrogenic.
