Illness beliefs and treatment outcome in chronic fatigue syndrome

Deale, Alicia, Chalder, Trudie, Wessely, Simon·1998·Journal of Psychosomatic Research

Abstract

Longitudinal studies have shown that physical illness attributions are associated with poor prognosis in chronic fatigue syndrome (CFS). Speculation exists over whether such attributions influence treatment outcome. This study reports the effect of illness beliefs on outcome in a randomized controlled trial of cognitive-behavior therapy versus relaxation. Causal attributions and beliefs about exercise, activity, and rest were recorded before and after treatment in 60 CFS patients recruited to the trial. Physical illness attributions were widespread, did not change with treatment, and were not associated with poor outcome in either the cognitive-behavior therapy group or the control group. Beliefs about avoidance of exercise and activity changed in the cognitive behavior therapy group, but not in the control group. This change was associated with improved outcome. These findings suggest that physical illness attributions are less important in determining outcome (at least in treatment studies) than has been previously thought. In this study, good outcome is associated with change in avoidance behavior, and related beliefs, rather than causal attributions.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Patients with CFS who have primarily physical subjective explanatory models may be hesitant to engage in a therapy that emphasizes psychological processes.

    “When these subjective explanatory models are primarily physical and not related to psychological processes (such as appraisals and dysfunctional coping behavior), they may be hesitant to engage in a therapy that emphasizes these aspects [19].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
