Pain
-
Although published treatment outcome studies for chronic pain have provided favorable support for the efficacy of many pain clinics and the use of specific modalities such as biofeedback and relaxation, there are several factors that mitigate against euphoria. Two related factors that influence interpretation of these reported outcomes are discussed, namely, noncompliance with therapeutic recommendations during treatment and subsequent to treatment termination, and relapse. Conceptual and methodological problems for establishing the prevalence of noncompliance and relapse are reviewed. ⋯ Studies on arthritis and heterogeneous pain clinic populations suggest that noncompliance and relapse are related; however, this association is less well established for headache patients. Strategies for assessing compliance (i.e., self-report, behavioral, biochemical, and clinical outcome) and the perspectives' of patients and health-care providers on the application of self-care recommendations are discussed. Strategic planning and adherence enhancement tactics to facilitate maintenance of post-treatment gains are described.
