Chronic Widespread Pain (CWP) is the cardinal feature of the fibromyalgia syndrome. It has a population prevalence of approximately 13% in the UK and is amongst the most common reasons for referral to a rheumatologist. Managing patients with chronic widespread pain is difficult. No individual management modality (pharmacological, physical, psychological therapies) has been demonstrated to be effective in relieving symptoms. Treatment is often prolonged and improvement likely to occur slowly. There is a need therefore to develop interventions at a primary care level that are potentially available to a large number of patients, which result in an improvement of symptoms, are acceptable and convenient to patients, and ideally which are inexpensive to provide.
Amongst patients with "unexplained" chronic widespread musculoskeletal pain that in addition to usual care:
1. A telephone-based Cognitive Behavioural Therapy (CBT) programme
2. Prescribed exercise
3. A combination of both treatments
will improve pain and disability in the short (6 months) and medium (9 months) term, in comparison to patients receiving "usual care" only.

Chronic Widespread Pain (CWP)
When eligibility is established and consent is obtained, subjects will be randomly allocated into one of four treatment groups, stratified by two important predictors of outcome: initial chronic pain grade score (I/II/III/IV) and by psychological distress (high/low). The four groups, which will be of equal size are:
Group 1: telephone-based CBT intervention (10 sessions in total)
Group 2: prescribed exercise intervention in a local leisure facility under the supervision of a fitness instructor (2 - 3 times a week)
Group 3: telephone-based CBT and prescribed exercise intervention
Group 4: treatment as usual
Each patient will receive the intervention for a period of 6 months.
Primary outcome measures
The primary outcome of the trial will be a self-rated clinical global impression change score at 6 (end of intervention) and 9 months post-randomisation. This is a seven-point scale measuring how participants feel that their health has changed since the period prior to entering the trial. It ranges from "I feel much worse" (score 1) to "I feel better" (score 6) and "I feel much better" (score 7).
Secondary outcome measures
4. Psychological distress
5. Sleep problems
6. Fear of movement
7. Quality of life
8. Treatment side-effects
This corresponds to the recommendations of core outcome domains for chronic pain clinical trials, and outcomes considered by the Outcome Measures in Rheumatology Clinical Trials initiative. All secondary outcomes will be measured at 6 and 9 months post-randomisation.
