Silvitra

By A. Kerth. Santa Clara University.

The research is correlational in nature and does not rule out the possibility that patient anxiety reflects a realistic interpretation of the circumstances sur- rounding surgery purchase 120mg silvitra with mastercard. It is also possible buy silvitra 120 mg cheap, however discount silvitra 120mg mastercard, that anxiety serves to limit activity and thus reduces the probability of a positive outcome order 120mg silvitra overnight delivery. In line with this interpretation purchase silvitra 120mg amex, concurrent psychological intervention with surgery may serve to enhance surgical outcome. That is, psychological interventions specifically aimed at anxiety reduction and improving self-efficacy and con- trol may serve to facilitate recovery in some patients. In particular, usage of imagery and relaxation strategies following surgery was associated with significantly greater knee strength, and less pain anxiety about reinjury. Overall, there appears to be increasing support for psycho- logical interventions in improving outcomes following surgery, but clearly more research is needed in this area. PAIN IN CHILDREN Prior to concluding, it must be acknowledged that this chapter, due largely to space constraints, has focused on psychological interventions for adults with chronic pain. We recognize that psychological interventions are also used to manage pain among children and adolescents (McGrath & Hillier, 1996; see also chap. Cognitive interventions with children typically focus on modifying thoughts and coping abilities related to pain (e. McGrath (1987), in particular, strongly advocated a multistrategy approach (both pharmaco- logical and nonpharmacological) for optimal management of recurrent per- 10. PSYCHOLOGICAL INTERVENTIONS AND CHRONIC PAIN 295 sistent pain that is tailored to the child and follows from the needs identi- fied through a multidimensional pain assessment. The interested reader is encouraged to review Eccleston, Morley, Williams, Yorke, and Mastroyan- nopoulou (2002), who conducted a recent systematic review and meta- analysis that shows good efficacy, but only really for headache, and second- arily for abdominal pain and sickle cell where there has been some prelimi- nary research. There is no controlled research on several major childhood chronic problems such as juvenile rheumatoid arthritis. CONCLUSION Although psychological treatments for chronic pain have been shown to be valuable, there is far greater support for CB interventions than any other form of treatment. Even with this form of treatment, however, there is a need for further research evaluations. A number of valuable recommenda- tions in this regard have been made (e. Morley and Williams (2002) most recently highlighted some of the issues that deserve reflection for those considering conducting and evaluating psychological treatments for chronic pain. A significant chal- lenge, for instance, is to understand why patients vary in their response to treatment and to develop interventions that are sensitive to individual needs. They further noted that there are severe limits to the extensive test- ing of all the parameters of treatment such as length and intensity. In this regard, they suggested that the way to move forward is through articula- tion of theories of change, of both specific and process components, to guide research on efficacy and effectiveness of treatment. In the selection and development of outcome measures they suggested that we need to ex- amine the needs of various stakeholders and that both qualitative and quantitative approaches to this research are required. Schwartz and colleagues (Schwartz, Cheney, Irvine, & Keefe, 1997) cau- tioned that clinical research on psychosocial interventions has flourished in the past two decades, and that due to the wide availability of interven- tions, reliance on standard no-treatment control conditions is really no lon- ger possible. A new design for randomized clinical trials is described by Schwartz’s group (1997) that does not require a no-treatment control group, and that potentially identifies dose-response relationships between inter- ventions and treatment outcomes. They proposed use of a three-arm varia- tion of a standard crossover trial. In the first arm patients receive active treatment followed by standard care; in the second arm patients receive standard care followed by active treatment; and in the third arm, patients receive active treatment throughout, allowing also for the study of dose- response relationships. The design avoids ethical difficulties by ensuring all 296 HADJISTAVROPOULOS AND WILLIAMS patients receive treatment and also in the final arm allows for study of the process of change. Most studies are hopelessly underpowered for their aims, and the use of treatment rather than no-treatment controls (as recommended) will require even larger samples to show differences. Based on review of the research as it stands, it is apparent that many pa- tients have benefited from the development of psychological interventions outlined here and are substantially better served than they were 40 years ago. There is now widespread acceptance for the role of psychological in- terventions in the treatment of chronic pain, and, in particular, it has been recommended that pain treatment facilities, in addition to physical therapy and education, include CBT on a routine basis (Fishbain, 2000). At the present time a CBT approach would appear to have the greatest support in working with pa- tients. Within this approach, however, there is considerable variability in how this can be applied, and until further research is available, clinicians are likely to continue to tailor their approach to the needs of the patients.
