Abstract
Both individual cognitive-behavioural therapy and short-term psychoeducational courses have shown to be effective in reducing hypochondriacal complaints. However, it is unknown which patients benefit from treatment. The aim of the present study is to explore which variables predict treatment outcome in a pooled group of 140 participants of a psychoeducational course. Predictor variables were a) pretreatment hypochondriasis, b) age, c) gender, d) level of education, e) duration of hypochondriacal complaints, f) severity of depressive complaints, g) severity of trait anxiety, and h) treatment expectation. The target scores were residual gain scores of hypochondriacal complaints. Results showed that more severe hypochondriacal complaints at pre- and post-test correlated significantly with more severe hypochondriacal complaints later. Furthermore, higher trait anxiety and older age predicted less treatment gain in hypochondriacal complaints. More research of which variables can predict treatment outcome is needed.

Abstract
We conducted this study to evaluate the clinical and disability status of injured workers 4.6 years after undergoing multidisciplinary pain center evaluation, comparing subjects who received treatment to subjects who were evaluated only. Three hundred injured workers were selected for a telephone survey; 150 had received pain center treatment and 150 had been evaluated but not treated. The survey included the SF-12, and questions about subjects' pain intensity and current work status. A workers' compensation database indicated the disability status of subjects. The response rate was 50%. In multivariate analyses, treated and evaluated-only subjects did not differ significantly in disability status, pain intensity, SF-12 scores, or current work status. At 4.6 years follow up, there was no evidence that pain center treatment affects either disability status or clinical status of injured workers.

Abstract
OBJECTIVES To analyse differences in demographic/financial/pain/health variables, disability, General Health Questionnaire (GHQ; i.e., depression symptoms) and coping among 949 primary care pain patients in various ages (20-65+ years) and to identify predictors of disability and coping. METHOD Patients completed scales about various areas (e.g., coping). The design was cross-sectional and data were collected during 15 consecutive days at 20 randomly selected primary care centres in Stockholm. RESULTS Univariate analyses showed that older patients (a) were more often divorced, blue-collar workers, less educated and had greater difficulties with living expenses, (b) had pain of longer duration, more frequently and of more complexity, and felt more disabled, (c) consumed more painkillers, analgesics, sedatives and other medications, had received more pain treatments and had more health problems and (d) more often used passive coping for pain. Younger patients (a) had more severe pain, were financially strained and were more often unemployed and (b) more often used active coping for pain. There were no significant differences concerning GHQ scores. Multivariate regression analyses showed that active coping was associated with younger age. High disability and passive coping were associated with older age. CONCLUSION We corroborated previous findings and may provide new insights into the experiences of older and younger pain patients. Further research concerning, for example, the elderly at risk of developing pain problems is needed.

Abstract
Using questionnaires, we analyzed associations between different pain variables (e.g., pain intensity) and age (20-65+ years) among 949 primary pain patients. Older patients (a) were more often divorced, were blue-collar workers, were less educated, and had greater difficulties with living expenses; (b) had pain of longer duration, more frequently and of more complexity, and felt more disabled; (c) consumed more painkillers, analgesics, sedatives, and other medications, and had received more pain treatments; and (d) had more health problems. Younger patients had more severe pain, were financially strained, and were more often unemployed. A multivariate regression analysis showed that high disability was more determined by older than young age. However, other factors (e.g., pain complexity) were also important. Thus, older and younger patients experienced their pain differently

Abstract
This study investigated the utility of the MMPI-2-based Personality Psychopathology Five (PSY-5) scales (Harkness, McNulty, & Ben-Porath, 1995) in the outcome prediction of behaviorally oriented chronic-pain treatment. The PSY-5 is a dimensional descriptive system for personality and its disorders. The sample consisted of 120 consecutive chronic-back-pain patients who followed a 4-week multimodal treatment program aimed at achieving a normal pattern of functioning, including return to regular work. The psychometric properties of the PSY-5 scales (Aggressiveness, Psychoticism, Constraint, Negative Emotionality/Neuroticism, and Positive Emotionality/Extraversion) were highly similar to the data reported by Harkness et al. (1995) and also corresponded to the characteristics of chronic-pain patients. The results of the hierarchical regression analyses provided support for the utility of the PSY-5 Positive Emotionality/Extraversion scale for the prediction of emotionally oriented outcome. We conclude that the PSY-5 model of personality psychopathology provides a solid basis for the more systematic study of the complex relation between personality characteristics and multidimensional treatment.

Abstract
Chronic pain in elderly people has only recently begun to receive serious empirical consideration. There is compelling evidence that a significant majority of the elderly experience pain which may interfere with normal functioning. Nonetheless, a significant proportion of these individuals do not receive adequate pain management. Three significant factors which may contribute to this are (1) lack of proper pain assessment; (2) potential risks of pharmacotherapy in the elderly; and (3) misconceptions regarding both the efficacy of nonpharmacological pain management strategies and the attitudes of the elderly towards such treatments. In this review the most commonly used assessment instruments and patterns of age differences in the experience of chronic pain are described and evidence for the efficacy of psychological pain management strategies for this group is reviewed.

Abstract
In a previous study it was concluded that only a few changes in symptoms related to craniomandibular dysfunction (CMD) could be attributed to therapy. It was suggested that psychosocial and socio-demographic variables, as well as symptom characteristics, could be responsible for the unconvincing treatment outcome in patients treated with a splint. The present study was performed to investigate whether socio-demographic characteristics, symptom characteristics and various psychosocial variables are associated with treatment outcome in patients with CMD treated with a splint. Treatment outcome was determined by using self-reported follow-up data. Results showed that patients with a negative treatment outcome were older, reported more and more severe symptoms and correlates of CMD, reported fewer stressors and more frequently considered health to be determined by external factors than patients who were treated successfully. The two groups could not be differentiated with regard to anxiety and depression. Results are interpreted with regard to the prediction of treatment outcome.

Abstract
Chronic pain treatment outcome studies have generated conflicting information on whether geriatric (age 65+) patients (1) benefit from pain center treatment, and (2) benefit as much as do other age groups. We asked chronic pain patients to rate themselves at pain center admission and discharge on 43 scales assessing area of pain, functional status, behavioral variables, and other areas (pain center modification goals). Patients were placed into one of three age groups: "geriatric" (n = 153); "middle aged" 45 to 64 years (n = 126); and "younger" 21 to 44 years (n = 191). First, tests of geriatric improvement were performed. Next, the three groups were compared on baseline variables and on overall admission, discharge, and change scores. Change scores of the three groups were compared using analysis of covariance, followed by pairwise post hoc tests. Overall, the geriatric group improved on 42 of the 43 scales (p < .001). Geriatric improvement was significant on 37 scales, with most scales being significant at p < .001. Geriatric patients were significantly different from the other two groups on most baseline variables. Their admission scores were better than the other two groups. Geriatric improvement was not significantly different from the other two groups on 37 of the scales. Geriatric change was significantly better on two scales and significantly worse on 4 scales. Geriatric chronic pain patients are (1) distinctly different from younger chronic pain patients, (2) show significant and meaningful improvement with pain center treatment, and (3) demonstrate as great an improvement as the other age groups in the majority of measures.

Abstract
This study compares the effectiveness of two methods of opiate reduction in 108 chronic pain patients during a 4 week inpatient pain management programme, and at 1-month and 6-month follow-up. Patients chose either the patient-controlled reduction (PCR) or cocktail reduction method, aiming to complete withdrawal by discharge. Use of opiates and other drugs was recorded, and psychological measures taken, at admission, at discharge, and at follow-ups. Patients who opted for the cocktail reduction method started at higher morphine equivalents (P < 0.001), were less confident in their ability to cope without medication (P < 0.05), and rated their everyday activities a more disrupted by pain (P < 0.05). At discharge, 89% of the cocktail group were abstinent from opiates compared with 68% of the PCR group (P < 0.05). By 1-month follow-up, the advantage of the cocktail method had disappeared, with no significant differences between the two groups in mean opiate dose, nor in the proportion of abstinent patients. This was the result of a greater return to opiate use in the cocktail group, with abstinence rates remaining unchanged in the PCR group. By 6-month follow-up, abstinence rates for the groups were equivalent, with 55% of patients remaining off opiates. By this stage, however, non-abstinent cocktail group patients were taking significantly larger doses of opiates than PCR patients (P < 0.05), although in both groups, the dose was well below admission level. Admission opiate dose level was the best predictor both of abstinence at discharge and of subsequent opiate dose level in non-abstinent patients. This study demonstrates that both reduction methods can produce substantial reduction in opiate use by severely impaired chronic pain patients with long medication histories.

Abstract
This article reviews the empirical data obtained in existing studies on the multimodal treatment of chronic pain. The majority of these 'treatment packages' are based on a cognitive/behavioural perspective. The articles for review were selected from the scientific literature on this subject which has appeared since the first publication of Fordyce in 1973. The following aspects have been analysed: the goal and structure of the treatment programmes; the method of evaluating treatment results; and the indications for treatment. Programmes for in-patients and out-patients have been compared because it is very likely that there are differences between the treatment methods and study populations. The interval validity and clinical relevance of the available research are discussed in the conclusion.

Abstract
The older segments of the U.S. population are expanding rapidly and account for a disproportionate amount of health care, including treatment for pain-related musculoskeletal disorders. In a prospective study with objective measures and one-year follow-up, Middaugh et al. (1988) found that older patients (55-78 yr; N = 17, 76% success) treated in a multidisciplinary chronic pain rehabilitation program enjoyed a success rate equal to that of younger patients (29-48 yr, N = 20, 70% success). The current study presents additional data on these two groups of patients to compare their ability to learn the physiological self-regulation skills taught in the biofeedback/relaxation component of the multimodal program. This component included progressive muscle relaxation training, diaphragmatic breathing instruction, and EMG biofeedback. Repeated measures ANOVA showed significant increases in digital skin temperature (peripheral vasodilation) and decreases in respiration rate both within and across training sessions (p values = .04 to .0001) with no differences between age groups (p greater than .05). EMG measures for the upper trapezius ms in patients with cervical pain showed similar deficits in muscle control at evaluation and similar improvements with biofeedback training for the two age groups. These findings indicate that older pain patients responded well to the biofeedback/relaxation training component of the multimodal pain program.

Abstract
Thirty-nine outpatients suffering from chronic pain were studied in a multidisciplinary program. Pain intensity on a visual analogue pain scale (VAPS), sensory decision indices of thermal discriminability, P(A), and pain report criterion, B, age and sex obtained before treatment, were used to predict the patients' status, determined by a follow-up questionnaire 6 mo later. The results showed that patients who were high on the VAPS at intake had shorter pain relief and decreased physical activities on follow-up. Patients with better thermal discriminability had greater pain relief, while those with low pain report criterion, that is, less stoical, demonstrated improved physical activity, and more social and hobby activities. Patients who were less stoical to thermal stimuli (lower pain criterion) took fewer centrally active drugs after treatment. Younger patients showed greater improvement at follow-up. The data indicate that the VAPS, thermal discriminability, and pain report criterion all predict the duration of pain relief after treatment. Nevertheless, each of these variables had its individual character. The VAPS was most efficient in predicting physical activities, thermal discriminability related best to pain relief, and pain report criterion to social and hobby activities as well as drug intake.

Abstract
An increasing number of chronic pain treatment outcome studies have appeared in the literature. In general, these studies support the efficacy of multidisciplinary pain programs, as well as specific treatment modalities such as biofeedback and relaxation. Reviews of this literature have tended to be cautiously optimistic. Some concerns, however, have been raised about the methodological adequacy of these studies, particularly in terms of the lack of control groups, the brief duration of follow-up periods, and the vague criteria used for establishing the success of the therapeutic interventions. Other factors that mitigate conclusions regarding the generalizability of the favorable results reported need to be considered. In this paper 3 rarely discussed topics that are implicit within most treatment outcome studies and that need to be given greater attention are examined. These topics include: (1) referral patterns to pain clinics (who are referred to pain clinics, when, and how representative is the referred sample?); (2) failure to enter treatment (e.g., exclusion criteria, lack of available financial support to cover the cost of treatment, patient's refusal to accept recommendations), and consequently, the representativeness of the treated sample; and (3) patient's attrition. In this paper we discuss each of these factors as they underscore important qualifications that have to be made in evaluating treatment outcome studies.

Abstract
Forty-eight chronic pain patients who were discharged from or left the 21-day inpatient component of a multidisciplinary pain program prior to completion were compared with a randomly selected matched group of program patients who stayed the entire 21 days. The purpose of the study was to determine if pre-admission factors are useful in predicting whether a chronic pain patient will complete an inpatient pain program. The results of pre-admission MMPI, POMS, MPQ, and information obtained from a questionnaire specially created for the program were studied. On the tests, the non-completers admitted to less psychopathology than those who did complete the program. The non-completers also had a higher number of pain-related surgeries and were more likely to be college graduates; limited social support from their families and lower MMPI premature termination scale scores were also found. Implications of these findings for the management of chronic pain patients are discussed.

Abstract
Long-term outcomes for 300 chronic back pain patients were assessed retrospectively by a telephone follow-up 4-6 years after the patients were evaluated by a multi-disciplinary rehabilitative program. A Perception of Disability scale, developed to rate subjective disability, was used along with objective measures of functioning. On objective measures, 56% of patients reported themselves working or work ready, 58% no longer received compensation, 62% were taking no prescription medications and 65% had no or brief medical treatment since evaluations. Perceived disability, however, suggested a bleaker outcome picture with only 29% of patients perceiving themselves as improving. There was a strong relationship between perceived disability and objective circumstances with 63% of the patients unable to work and 61% still on disability payments reporting their disability as increasing. Of the 48 patients reporting back surgery at some point after evaluation only 17% perceived themselves as improved while 58% considered themselves worse. These results are discussed in the context of the development of pain focussed lifestyles.

Abstract
In response to an earlier published paper by Fordyce, some assumptions underlying the behavior management paradigm of chronic pain are critically discussed. While operant treatment has proved successful, the conclusion that operant factors play an important role in the development and maintenance of chronic benign pain is debated. Some empirical studies, regularly used to demonstrate this role, are re-evaluated. An alternative theory is proposed for chronic pain behavior, in which the role of a lower tolerance to proprioceptive stimuli, which may include more than just pain stimuli, is emphasized.

Abstract
The Minnesota Multiphasic Personality Inventory (MMPI) is widely used in the psychological assessment of patients with chronic low back pain (LBP). Patients' profiles have been used in a number of ways: in attempts to discriminate between cases; as predictors of both medical treatment and pain management program outcomes; and in attempts to assess degree of disability. Studies reviewed here indicate that the concept of psychological etiology of chronic LBP, despite widespread use, has failed to differentiate patients and to reliably predict response to specific treatment. A promising alternative approach has emerged in recent years: profile distinctions between different types of psychological response to chronic LBP. These subgroups are associated with different pain-related behaviors and may show differential response to various treatments, although further work remains to be done to specify the relationships more precisely. Methodological difficulties that continue to appear in the literature are addressed and recommendations for further developments in the use of the MMPI with this patient population are made.

Abstract
This paper considers the reliability and validity of pain assessment methods in mechanical dysfunction. A distinction is drawn between measures of subjective report and those of pain behaviour. The latter is observable and therefore more amenable to direct study than subjective report. Measures of subjective report include rating scales, the McGill Pain Questionnaire, and diary cards. Consideration is also given to personality assessment in this context. It is concluded that measurement needs to proceed from a number of standpoints, with the importance of each of these dependent upon the context. For chronic pain, emphasis on pain behaviours is appropriate.

Abstract
Previous reports on the use of the MMPI with chronic pain patients have produced a variety of results. No single configural feature or scale identifies the chronic pain patient, regardless of the origin or verifiability of the etiology of the pain. Elevations on the neurotic triad occur frequently, but do not have the specificity of more recently reported chronic-pain subtypes on the MMPI. The present nonexperimental study (N = 72) provides an example of a multi-method analysis of a carefully selected sample of chronic pain patients without physical findings. Blind clinical analysis, simple two-point code aggregation, and multivariate profile methods were used and produced similar subtypes of the sample and understanding of the data. The obtained sample subtypes were similar to those found in other studies and were hypothesized to be related to each other along an underlying continuum of what might be depression. Further research is needed to facilitate understanding of the causation of chronic pain of obscure origin.

Abstract
Although it has often been suggested that chronic pain patients who are receiving workmen's compensation or who have litigation pending are less likely to benefit from treatment, the results of outcome studies of this question conducted by various pain clinics have been inconsistent. We hypothesized that poorer outcome in such patients may be related to the fact that they are less likely to be working and that the inconsistent results in the literature may therefore be explained by variability among studies in the percentages of patients who are receiving compensation (or who have litigation pending) who are also working. We examined the relationships among compensation, litigation, employment, and short- and long-term treatment response in a series of 454 chronic pain patients. Compensation benefits and employment status both predicted poorer short-term outcome in univariate analyses; however, when employment and compensation were jointly used to predict outcome in multiple regression analyses, only employment was significant. In additional analyses, only employment significantly predicted long-term outcome, whereas compensation and litigation did not. Our results suggest that it would be valuable to redirect attention away from the deleterious effects of the 'compensation neurosis' and toward the roles of activity and employment in the treatment and rehabilitation of chronic pain patients.

Abstract
Eighteen patients with chronic musculoskeletal pain completed a trial of EMG feedback where each subject was exposed to biofeedback, a control condition and a waiting list. Pain scores were determined pre- and posttrial, and the percentage change calculated for each subject. EMG activity and present pain measured during the trial gave an EMG/pain correlation for each patient. A repertory grid was completed by each patient at the pretrial evaluation. Repertory grid technique is a highly flexible way of measuring subjective data such as attitudes. The specific test used involved the patient in rating a series of 6 self-concepts across 8 'constructs' or concepts concerning illness and emotional distress. The resulting matrix of 48 ratings was analysed to produce a measurement of 'distance' between the self and ideal-self concepts. The major finding was that the self-ideal-self distance was significantly positively correlated with pain score changes by rank correlation. The self-ideal-self distance is essentially a measure of self-satisfaction or dissatisfaction and the results imply that patients who show a relatively greater degree of self-dissatisfaction are more likely to respond well to EMG feedback. In addition, patients with high EMG/pain correlations had a better outcome and this measure also correlated with pain scores. The relationship between self-concepts and EMG/pain correlations is discussed. The Illness Self-Concept Repertory Grid appears capable of predicting treatment outcome and shows promise as a prognostic tool.
