Depression research and treatment: are we skating to where the puck is going to be?

This paper critically reviews empirical findings regarding current key assumptions underlying the nature and treatment of depression which heavily rely on the DSM approach. This review shows that empirical evidence provides little support for these assumptions. In response to these findings, an etiologically based, biopsychosocial, dynamic interactionism model of depression is proposed. This model could foster further integration in research on depression and assist in the development of guidelines for the treatment of depression that are better informed by research findings and more congruent with complex clinical realities.

Does methylphenidate reduce the symptoms of chronic fatigue syndrome?

PURPOSE: Chronic fatigue syndrome is a clinical entity consisting of prolonged and debilitating fatigue in which concentration disturbances are very frequent. Until now, no medical treatment has shown any efficacy. The objectives of this study were to investigate the short-term effects of methylphenidate, an amphetamine derivative, on fatigue, concentration disturbances, and quality of life. SUBJECTS AND METHODS: A double-blind randomized placebo-controlled crossover study was conducted in 60 patients who fulfilled the 1994 Centers for Disease Control criteria for chronic fatigue syndrome and had concentration difficulties. Patients were enrolled between March 2003 and March 2004 at the outpatient department of a university hospital referral center for chronic fatigue syndrome patients. Random assignment to 4 weeks treatment with methylphenidate 2 x 10 mg/day, followed by 4 weeks of placebo treatment, or 4 weeks of placebo treatment, followed by methylphenidate treatment. Fatigue and concentration were measured with a Checklist Individual Strength (CIS) and a Visual Analogue Scale (VAS). RESULTS: Fatigue scores fell significantly during methylphenidate intake in comparison with baseline (mean difference: -0.7, P = .010 for VAS; mean difference: -11.8, P <.0001 for CIS) and in comparison with placebo (mean difference: -1.0, P = .001 for VAS; mean difference: -9.7, P <.0001 for CIS). Concentration disturbances, measured with a VAS improved significantly under methylphenidate treatment compared with baseline (mean difference: -1.3, P <.0001) and compared with placebo (mean difference: -1.1, P <.0001). A clinical significant effect (> or =33% improvement or CIS < or =76) on fatigue was achieved in 17% of patients, who were considered responders; on concentration in 22% of patients. CONCLUSIONS: Methylphenidate at a dose of 2 x 10 mg/day is significantly better than placebo in relieving fatigue and concentration disturbances in a minority of chronic fatigue syndrome patients. Further studies are needed to investigate the long-term effects of this treatment.

In search of a new balance. Can high "action-proneness" in patients with chronic fatigue syndrome be changed by a multidisciplinary group treatment?

OBJECTIVE: The purpose of this study is to investigate changes in action-proneness (a cognitive and behavioral tendency toward direct action) after a multidisciplinary group intervention, including cognitive behaviour therapy (CBT) and graded exercise therapy (GET). METHODS: Patients with chronic fatigue syndrome (n=62) completed three versions of a Dutch self-report questionnaire evaluating action-proneness retrospectively that is (1) before illness onset, (2) before treatment and (3) after treatment. Significant others (n=62) also gave their opinion about the patients' action-proneness at time points 1 and 2. RESULTS: Premorbid action-proneness levels considerably dropped after illness onset. After treatment, action-proneness levels significantly increased again, although levels remained below premorbid levels. CONCLUSION: High action-proneness retrospectively reported by CFS patients can be adaptively modified by a multidisciplinary group treatment including CBT and GET.

Well-being in patients with chronic fatigue syndrome: the role of acceptance.

OBJECTIVE: Research in chronic pain patients has shown that accepting the chronic nature of their illness is positively related to quality of life. The aim of this study was to investigate whether acceptance is also associated with better well-being in patients suffering from chronic fatigue syndrome (CFS). METHODS: Ninety-seven patients completed a battery of questionnaires measuring fatigue, functional impairment, psychological distress, and acceptance. RESULTS: Results indicated that acceptance has a positive effect upon fatigue and psychological aspects of well-being. More specifically, acceptance was related to more emotional stability and less psychological distress, beyond the effects of demographic variables, and fatigue severity. CONCLUSION: We suggest that promoting acceptance in patients with CFS may often be more beneficial than trying to control largely uncontrollable symptoms.

The role of life stress in fibromyalgia.

This paper focuses on recent evidence of etiopathogenetic links between fibromyalgia and life stress. From an etiologic point of view, studies concerning the role of adverse life events, personality and lifestyle factors, post-traumatic stress, and negative childhood experiences are reviewed. From a pathogenetic point of view, neurobiologic links between stress and fibromyalgia symptoms, notably chronic pain and fatigue are highlighted. Finally, several methodologic issues with regard to stress research on fibromyalgia, as well as the clinical relevance of the stress concept for fibromyalgia are discussed.

Combination therapy with hydrocortisone and fludrocortisone does not improve symptoms in chronic fatigue syndrome: a randomized, placebo-controlled, double-blind, crossover study.

PURPOSE: Chronic fatigue syndrome has been associated with decreased function of the hypothalamic-pituitary-adrenal axis. Although neurally mediated hypotension occurs more frequently in patients with chronic fatigue syndrome than in controls, attempts to alleviate symptoms by administration of hydrocortisone or fludrocortisone have not been successful. The purpose of this study was to investigate the effect of combination therapy (5 mg/d of hydrocortisone and 50 microg/d of 9-alfa-fludrocortisone) on fatigue and well-being in chronic fatigue syndrome. METHODS: We performed a 6-month, randomized, placebo-controlled, double-blind, crossover study in 100 patients who fulfilled the 1994 Centers for Disease Control and Prevention criteria for chronic fatigue syndrome. Between-group differences (placebo minus treatment) were calculated on a 10-point visual analog scale. RESULTS: Eighty patients completed the 3 months of placebo and 3 months of active treatment in a double-blind fashion. There were no differences between treatment and placebo in patient-reported fatigue (mean difference, 0.1; 95% confidence interval [CI]: -0.3 to 0.6) or well-being (mean difference, -0.4; 95% CI: -1.0 to 0.1). There were also no between-group differences in fatigue measured with the Abbreviated Fatigue Questionnaire, the Short Form-36 Mental or Physical Factor scores, or in the Hospital Anxiety and Depression Scale. CONCLUSION: Low-dose combination therapy of hydrocortisone and fludrocortisone was not effective in patients with chronic fatigue syndrome.

Acceptance of pain is an independent predictor of mental well-being in patients with chronic pain: empirical evidence and reappraisal.

This paper reports upon: (1) the value of acceptance of pain in predicting well-being in patients suffering from chronic pain and (2) the construct validity of acceptance by comparing two questionnaires designed to measure acceptance (the Chronic Pain Acceptance Questionnaire, CPAQ, unpublished doctoral dissertation, University of Nevada, Reno, NV, 1992 and the Illness Cognitions Questionnaire, ICQ, J Consult Clin Psychol 69 (2001) 1026). The results of two independent cross-sectional studies are reported. Study 1 included 120 patients seeking help in tertiary care settings. In Study 2, 66 patients were recruited from a self-support group for fibromyalgia patients and from a pain clinic. Both studies revealed that acceptance of pain predicted mental well-being beyond pain severity and pain catastrophizing, but did not account for physical functioning. In both instruments, it was found that acceptance of pain was strongly related to engagement in normal life activities and the recognition that pain may not change. Acceptance in both instruments was strongly related to a cognitive control over pain. Study 2 further revealed that the correlation between the CPAQ and the ICQ is moderate, indicating that both instruments measured different aspects of acceptance. It is concluded that acceptance of chronic pain is best conceived of as the shift away from pain to non-pain aspects of life, and the shift away from a search for a cure with an acknowledgement that pain may not change.

A confirmatory factor analysis of the Pain Catastrophizing Scale: invariant factor structure across clinical and non-clinical populations.

This study examined the factor structure of the Pain Catastrophizing Scale in three different Dutch-speaking samples: 550 pain-free students, 162 chronic low back pain patients, and 100 fibromyalgia patients. Confirmatory factor analyses were used to compare three different models of pain catastrophizing (one factor, two oblique factors, three oblique factors), and to investigate the invariance of the factor structure across the three different samples. The results indicated that a three-factor oblique model with a four-item rumination factor, a three-item magnification factor, and a six-item helplessness factor provided the best fit to the data in the three samples. Furthermore, it was found that this model could be considered as invariant across three samples (pain-free students, chronic low back pain patients, and fibromyalgia patients) and across gender, indicating that the same processes are measured in different subgroups.

Spinal cord stimulation in Belgium: a nation-wide survey on the incidence, indications and therapeutic efficacy by the health insurer.

The present report describes a nation-wide survey on the incidence, the indications and the efficacy of spinal cord stimulation (SCS), as assessed by the Belgian health authorities. The direct motive for this survey was the rapidly growing expenditures resulting from the increasing use of SCS. Between 1983 and 1992, nearly 700 SCS devices were implanted for a population of less than 10 million inhabitants. The most common indication for SCS was failed back survey (61.4%). Whereas SCS was initially only performed in university teaching hospitals, it is now also widely practised in general hospitals. In 3 studies, the efficacy of SCS was assessed. In a first study, success was defined in terms of resumption of professional activities. After a mean follow-up of more than 1 year, less than 5% of the 147 patients treated with SCS had returned to work. A second study investigated the subjective evaluation of the therapy by the patient. Seventy patients with a mean follow-up of 3.5 years were studied. In 52% of the patients, the effect of SCS was judged as good to very good. Men scored better than women. In addition, the results obtained in the teaching hospitals were significantly better than those obtained in general hospitals. In a third study, the impact of psychiatric screening on patient selection was evaluated. Of the 100 candidates, 36 were withheld from implantation with a SCS device because of psychiatric contra-indications. Patients who had received a positive psychiatric advice showed a significantly better therapeutic outcome than patients for whom the psychiatrist had made reservations.
