A questionnaire study was performed in order to clarify knowledge and practice of cancer pain treatment in Norway: a 10% random sample of Norwegian physicians received a questionnaire. Of 800 correctly addressed questionnaires, 549 were returned and 306 were analyzed after exclusion of those doctors who never treated cancer patients. Their knowledge of the principles and methods of cancer pain treatment were evaluated with 8 multiple-choice and 13 open questions. ⋯ Two hundred seventy-four (97%) of the physicians said they experienced problems when treating cancer pain, ranging from inefficient pain relief (52%) to side effects of opioid analgesics (32%), most often sedation, in combination with nausea and constipation. Only 13% of the physicians had a correct understanding of opioid drug dependence. As many as 72% of Norwegian physicians thought their education in cancer pain treatment was insufficient.

Although a number of self-report indices that measure intensity and psychosocial components of the pain experience are available, these measures do not assess the range of cognitive, behavioral, and physiological reactions frequently associated with pain. This paper describes the initial determination of the psychometric properties of the Biobehavioral Pain Profile (BPP) developed to measure these reactions. The BPP is a 41-item self-report scale tested in a sample of 617 subjects with chronic recurrent pain, chronic non-malignant pain or chronic malignant pain. ⋯ Test-retest reliability for the scales ranged from 0.57 to 0.73. Low correlations among the BPP and general indices of fear, depression, anxiety, body consciousness and social desirability are reported. The BPP appears to provide a unique composite assessment of self-report of behavioral, physiological, and cognitive reactions to pain experienced by individuals with a wide range of pain problems.

It is being increasingly recognized that the solution to the problem of inadequate postoperative pain relief lies not so much in development of new techniques but in development of a formal organization for better use of existing techniques. Acute Pain Services (APS) are being increasingly established to provide good quality postoperative analgesia. In the United States such 24-h services usually consist of anesthesiologists, residents, specially trained nurses and pharmacists. ⋯ Regular recording of each patient's pain intensity by VAS every 3 h and recording of treatment efficacy on a bedside vital-sign chart are the cornerstones of this model. A VAS greater than 3 is promptly treated. Surgeon and ward nurse participation are crucial in this organization.(ABSTRACT TRUNCATED AT 250 WORDS)

Review Historical Article
The role of psychological factors in chronic pain. I. A half century of study.
This review examines a half century of thought about the role of psychological factors in chronic pain. Changing views are discussed, and representative examples of pain research based on psychoanalytic, behavioural, cognitive, and psychophysiological theories are presented and evaluated. ⋯ Studies reviewed show that an earlier concept, based on simple formulations of psychological causation, has been replaced by more comprehensive explanations comprising both physical and psychological influences. Further methodological and conceptual problems are discussed in the second paper of this 2-part review.

Chronic pain and depression often coexist, but there is still uncertainty about the nature of this relationship. Virtually all the available data are cross-sectional and therefore do not clarify the causal relationship between the two variables. In epidemiological studies, chronic pain has often been defined fairly liberally in terms of the actual duration. ⋯ Those with data on both occasions represent 76% of an initial population of 3059 persons. On logistic regression analysis depressive symptoms at year 1 significantly predicted the development of chronic musculo-skeletal pain at year 8 with an odds ratio of 2.14 for the depressed subjects compared with the non-depressed subjects. In patients in whom pain was present at baseline no socio-demographic variable alone predicted its persistence; however, male sex and white race together with 2 items of the CES-D did predict the persistence of existing pain.(ABSTRACT TRUNCATED AT 250 WORDS)
