Is there a link between 'pain-proneness' and 'action-proneness'?

Determinants of representational and behavioral hyperactivity in patients with fibromyalgia syndrome

Fibromyalgia is associated with a premorbid hyperactivity. This study examines how contextual and personality factors contribute to premorbid hyperactivity. A total of 45 patients completed questionnaires. The results show that the number of children and the basic bodily needs neglect (and their interaction) explain nearly 50 percent of the variance of hyperactivity. The neglect toward bodily needs completely mediates the relation between self-oriented perfectionism and hyperactivity. This study suggests that hyperactivity itself would not have a pathological value, but that the neglect of basic bodily needs would represent a vulnerability factor in a hyperactive premorbid lifestyle in fibromyalgia patients.

The prevalence and impact of early childhood trauma in Chronic Fatigue Syndrome

BACKGROUND

Although some studies have found high rates of early childhood trauma in Chronic Fatigue Syndrome (CFS), the role of early trauma in this condition remains controversial.

METHODS

This study examined the prevalence of early childhood trauma and its impact on daily fatigue and pain levels over a 14-day period in a sample of 90 carefully screened CFS patients using a diary method approach. Data were analyzed using multilevel analysis.

RESULTS

More than half of the patients (54.4%) had experienced at least one type of early trauma, with the majority of these patients reporting multiple traumas. Prevalence rates were particularly high for emotional trauma (i.e., emotional abuse and/or emotional neglect) (46.7%). Moreover, total trauma scores and emotional abuse significantly predicted higher levels of daily fatigue and pain over the 14-day period, even when controlling for demographic features and depressed mood.

CONCLUSIONS

This is the first study to demonstrate that early childhood trauma predicts increasing levels of core symptoms of CFS in the daily flow of life. Moreover, findings of this study suggest that emotional trauma may be particularly important in CFS.

Self-critical perfectionism and its relationship to fatigue and pain in the daily flow of life in patients with chronic fatigue syndrome

BACKGROUND

Research suggests that the personality factor of self-critical or maladaptive perfectionism may be implicated in chronic fatigue syndrome (CFS). However, it is not clear whether self-critical perfectionism (SCP) also predicts daily symptoms in CFS. Method In the present study we investigated whether SCP predicted fatigue and pain over a 14-day period in a sample of 90 CFS patients using a diary method approach. After completing the Depressive Experiences Questionnaire (DEQ) as a measure of SCP, patients were asked each day for 14 days to complete Visual Analogue Scales (VAS) of fatigue, pain and severity of depression. Data were analysed using multilevel analysis.

RESULTS

The results from unconditional models revealed considerable fluctuations in fatigue over the 14 days, suggesting strong temporal variability in fatigue. By contrast, pain was relatively stable over time but showed significant inter-individual differences. Congruent with expectations, fixed-effect models showed that SCP was prospectively associated with higher daily fatigue and pain levels over the 14-day period, even after controlling for levels of depression.

CONCLUSIONS

This is the first study to show that SCP predicts both fatigue and pain symptoms in CFS in the daily course of life. Hence, therapeutic interventions aimed at targeting SCP should be considered in the treatment of CFS patients with such features.

Multidisciplinary pain education program (MPEP) for chronic pain patients: preliminary evidence for effectiveness and mechanisms of change

OBJECTIVE

There is a need for effective brief interventions in chronic pain patients, and the identification of mechanisms of change.

METHOD

In the present study, we tested the effectiveness of MPEP (Multidisciplinary Pain Education Program), a very brief, four-session cognitive-behaviorally based psycho-educational intervention for chronic pain using a pre-and post-test design. In addition, pre- to post-treatment change scores were calculated to investigate factors associated with change in pain. Participants of the study were 53 patients with chronic non-cancer pain. Primary outcome measures were (1) pain severity, (2) health perception, and (3) severity of depression. Secondary outcome measures included factors that have been implicated in the maintenance of chronic pain and that might be associated with worse treatment outcome: (1) catastrophizing, (2) kinesiophobia, and (3) action-proneness.

RESULTS

Findings provided preliminary evidence for the effectiveness of MPEP in that patients showed significant and clinically meaningful improvements in pain symptoms (F = 24.503, p < 0.001, d = 0.59) and action-proneness (F = 178.504, p < 0.001, d = 1.95), and small improvements in health perception (F = 7.116, p < 0.05, d = 0.30). Furthermore, results showed that changes in catastrophizing (β = -0.455, p = 0.001) and severity of depression (β = -0.300, p < 0.05) were independently and significantly associated with changes in pain. However, changes in health perception, kinesiophobia, and action-proneness were not significantly associated with changes in pain (β = 0.203, ns; β = 0.003, ns; and β = 0.154, ns, respectively). Importantly, duration of chronic pain was not related to treatment outcome (β = 0.070, ns).

CONCLUSIONS

Overall, this study provides preliminary evidence for the effectiveness of MPEP and possible mechanisms through which MPEP is effective. Yet, further research is needed to investigate the efficacy of MPEP.

[The psychosomatics of chronic back pain. Classification, aetiology and therapy]

An overview is given on the current classification, description and treatment of chronic pain with causally relevant psychological factors. It is based on the "practice guidelines on somatoform disorders" and on a thematically related meta-analysis. The classificatory problems, especially of the demarcation of somatoform and other chronic pain, are presented. Additional descriptive dimensions of the relevant psychosocial factors are: pain description, other organically unexplained pain- and non-pain-symptoms, anxiety and depression, disease conviction and illness behaviour, personality and childhood abuse. A modified psychotherapy for (somatoform) chronic pain is outlined. Finally, this aetiologically oriented psychosomatic-psychiatric approach is compared to psychological coping models for chronic pain.

Chronic fatigue syndrome and fibromyalgia: clinical assessment and treatment

Chronic fatigue syndrome (CFS) and fibromyalgia (FM) are closely related illnesses of uncertain etiology. This article reviews the research literature on these biobehavioral conditions, with an emphasis on explanatory models, clinical evaluation of comorbid psychiatric disorders, assessment of stress factors, pharmacologic and alternative therapies, and cognitive-behavioral treatment studies. Furthermore, clinical protocols suitable for professional practice are presented based on an integration of the authors' clinical observations with published data. The article concludes with the recognition that mental health professionals can offer substantial help to these patients.

Does high 'action-proneness' make people more vulnerable to chronic fatigue syndrome? A controlled psychometric study

Degree of premorbid 'action-proneness' was measured, using a self-administered questionnaire, in 35 patients suffering from chronic fatigue syndrome (CFS), all the members of 'ME'-self help groups and all those meeting CDC-criteria of CFS. The results were compared with those of 30 chronic idiopathic musculoskeletal pain patients, 34 patients with a chronic organic condition, and 34 neurotic patients without primary somatic complaints. Statistical analysis showed that CFS patients described themselves as significantly more 'action-prone' than the last two groups, and to a degree which was comparable with the chronic pain group. The results could not be explained by concomitant depression and are in accordance with anecdotal reports of premorbid hyperactive lifestyle in CFS patients. Further investigations seem worthwhile to test the hypothesis that hyperactivity might be a predisposing factor for chronic illness behaviour in CFS patients.

The role of psychological factors in chronic pain. II. A critical appraisal

This paper, the second of two, concerning the study of psychological factors in chronic pain, presents a critical appraisal of the literature. Questionable assumptions, flawed methodology, and conceptual problems in earlier work are discussed, as are gradual improvements in methodological rigour and conceptual clarity. Methodological weaknesses in studies, including lack of control groups, selection biases, overinterpretation of correlational data, and use of inappropriate testing instruments are examined. Questions are raised about persisting tendencies to split mind from body by attributing pain to either organic or psychological causes. Despite advances in research and thinking in recent years, several issues remain unresolved in both the research enterprise and the clinical setting. These are discussed in relation to the respective needs of the researcher, the clinician, and the patient. Limitations on research conducted in clinical settings are considered and targets for improved methodology in studies are identified.
