SOCIAL INFLUENCES ON PAIN RESPONSE 189 tors that mediate the painful experience buy naltrexone 50mg amex. Kiecolt-Glaser and colleagues re- cently reviewed considerable evidence and confirmed that stress delays wound healing (Kiecolt-Glaser buy naltrexone 50mg with amex, Page naltrexone 50mg on line, Marucha generic naltrexone 50 mg without prescription, MacCullum cheap 50mg naltrexone with mastercard, & Glaser best 50 mg naltrexone, 1998). As pain is a prominent stressor, this has implications for the induction and perpetuation of chronic pain at physiological and neurological levels. Other research has shown that interpersonal stress is associated with an increase in disease activity in rheumatoid arthritis patients (Zautra et al. Taken together, this research highlights that the response to pain and its consequences can be influenced by factors external to the individual, and that this complex relationship has only just begun to be unraveled. Li and colleagues looked at whether pain perception differed between older and younger adults (Li, Greenwald, Gennis, Bijur, & Gallagher, 2001). Pa- tients requiring a painful procedure—in this case, the insertion of an intrave- nous catheter during attendance at an emergency department—were asked to rate their pain on a visual analogue scale. The results showed that adults over 65 years reported significantly less pain than younger people, and this result was not influenced by gender. However, this study is unable to dem- onstrate whether such differences could be explained by a decline in sensi- tivity to pain or a reduced willingness to complain of pain, which may have implications for treatment. Having identified differences in the response to pain by people of different age groups, it follows that this is an important area of inquiry and should be considered when approaching the manage- ment of pain. Other influences on the response to pain derive from the complex inter- play of biological, hormonal, molecular, and genetic determinants, which are important at Level 1 of this model for understanding pain (see chap. Recently there has been an explosion of interest in the genetic mechanisms underlying pain, although this area of research is beyond the scope and direction of this chapter. Research examining these features of pain is well documented elsewhere; for example, for ge- netic variation see Hakim, Cherkas, Zayat et al. Furthermore, these types of research are beginning to indicate that individuals respond differently to analgesics, and there has been some work to elucidate the possible mechanisms involved (Amanzio, Pollo, Maggi, & Benedetti, 2001). Level 2: Interpersonal Behavior Current and future expectations about pain, illness, treatments, and a “cure,” link Level 1 to Level 2 of the model. Level 2 is characterized by be- liefs about pain and treatment, the context of encounters, and social atmo- 190 SKEVINGTON AND MASON sphere and motivation. Beliefs about pain and treatment are socially shared, and include the nature of pain, illness, and disability, attributions about their causation, the efficacy of particular interventions, self-efficacy in implementing treatment, and aspects of pain control, such as choice and predictability. The social context of interpersonal encounters encompasses the social relationships with family, significant others, friends, acquain- tances, workmates, colleagues, health professionals, and alternative practi- tioners. Social motivation incorporates social support, the need for ap- proval of actions to utilize social resources such as family and friends and formal health care resources, and seeking help from alternative therapists. Numerous beliefs, probably in the hundreds, need to be systematically documented and organized taxonomically to understand which are the most important predictors of the response to pain, illness, and treatment outcomes. Patients’ beliefs tend to mirror the general and current views held by the society that they live in, being grounded in that culture. These interpersonal beliefs provides a backdrop for shared group and intergroup understandings at Level 3, and connect with higher order factors such as health culture at Level 4. Beliefs have considerable practical value in under- standing how patients present their condition, and in predicting their re- sponse to advice and compliance with treatment, with erroneous beliefs be- ing particularly prone to perpetuating persistent pain. Identifying several clusters of relevant beliefs, Jensen, Karoly, and Huger (1987) found that pain patients commonly believe that physicians will rid them of pain, that they themselves are not in control of the pain, that others are responsible for helping people in pain, that those in pain are permanently disabled, and that medication is the best form of treatment for pain. These beliefs are conceptualized as reflecting dependency, external health locus of control, absence of positive thoughts about rehabilitation, or catastrophizing, and medicalization, respectively.

Paul Dirac (theoretical physicist discount naltrexone 50 mg without a prescription, 1980) The size of your study sample is of paramount importance for testing your hypothesis or fulfilling the study aims 50 mg naltrexone with visa. The number of participants in any study should be large enough to provide precise estimates of effect and therefore a reliable answer to the 59 Scientific Writing research question being addressed naltrexone 50 mg without prescription. You may be under some pressure to publish your work quickly, but your study should not be stopped or written up before an adequate number of participants has been recruited and studied. Even if formal sample size calculations suggested that you only needed a small number of participants, it is usually difficult to interpret the results from studies with fewer than 30 participants in each group. When the sample size is smaller than this, the results are rarely believable, the summary estimates lack precision, standard statistical methods may be inappropriate, and the generalisability of the results will be questionable. Providing a reliable answer to a study question usually means recruiting larger numbers of participants and, in terms of scientific integrity, it is worth going the hard yard to do this. It is always important to include details of your sample size calculations. Your readers will need to know what outcome variables your study was designed to detect a difference in, what size of difference you initially expected, what power level you were working with, and why you chose a particular sample size. In practice, many studies with negative results do not have a large enough sample size to show that clinically important differences are statistically significant. If your statistics lead you to accept the null hypothesis, having set up an experiment to disprove it, fellow scientists are entitled to information about the effect size that you considered clinically important at the outset. The probability that your findings were a result of type I and type II errors, which are explained in Box 3. This usually happens because the study is overpowered in terms of sample size and the result is that the null hypothesis is rejected in error. Type II errors Errors that occur when a clinically important difference between two groups fails to reach statistical significance. This usually happens 60 Writing your paper when the study is underpowered in terms of sample size and the result is that the null hypothesis is accepted in error. Power Chance of finding a statistically significant difference when there is one, or of rejecting the null hypothesis. A study with a power of 80% has a 20% chance of a type II error occurring. Probability Level at which a difference between groups is considered statistically significant, for example P < 0·05. If not, your theory is apt to be based more upon imagination than upon knowledge. William Thompson (physicist, 1927) Many research studies use questionnaires to collect information about the participants’ characteristics, exposure to environmental risk factors, current and previous illness history, and so on. In the methods section, you should give precise details of the questionnaires you used and how they were developed, validated, and tested for repeatability. The mode of administration must also be spelt out since different types of bias can arise when questionnaires are self-administered, telephone-administered, or interviewer-administered. A questionnaire that is thoughtfully designed has good face, content and construct, or criterion validity that minimises both measurement bias and the amount of missing or unusable information. If your questionnaire has been validated, always give a reference to the work. But a pile of stones is not a house and a collection of facts is not necessarily science. It is important to include exact details of the intervention of interest, and the intervention, sham, or placebo that was used for comparison.
