Effectiveness of a group-based self-management program for people with chronic fatigue syndrome: a randomized controlled trial.

Objective: To evaluate the effectiveness of a group-based self-management program for people with chronic fatigue syndrome.

Design: A randomized controlled trial.

Setting: Four mid-sized towns in southern Norway and two suburbs of Oslo.

Subjects: A total of 137 adults with chronic fatigue syndrome.

Intervention: A self-management program including eight biweekly meetings of 2.5 hours duration. The control group received usual care.

Main Measures: Primary outcome measure: Medical Outcomes Study-Short Form-36 physical functioning subscale.

Secondary Outcome Measures: Fatigue severity scale, self-efficacy scale, physical and mental component summary of the Short Form-36, and the illness cognition questionnaire (acceptance subscale). Assessments were performed at baseline, and at six-month and one-year follow-ups.

Results: At the six-month follow-up, a significant difference between the two groups was found concerning fatigue severity ( p = 0.039) in favor of the control group, and concerning self-efficacy in favor of the intervention group ( p = 0.039). These significant differences were not sustained at the one-year follow-up. No significant differences were found between the groups concerning physical functioning, acceptance, and health status at any of the measure points. The drop-out rate was 13.9% and the median number of sessions attended was seven (out of eight).

Conclusions: The evaluated self-management program did not have any sustained effect, as compared with receiving usual care.
