Patients' initial beliefs about the success of a given pain treatment
are shown to have an important influence on the final treatment outcome.
This study used the data from two randomized clinical trials evaluating
the effectiveness of cognitive-behavioral interventions for 171 patients
with fibromyalgia and chronic low back pain. Treatment expectancy was
measured by a short questionnaire. Four outcome variables were measured
before and after the intervention and a 12 months follow-up (pain coping
and control, motor behavior, negative affect, and quality of life).
Patients with higher treatment expectancies significantly received less
disability compensation and were less fearful. Pre-treatment expectancy
significantly predicted each of the 4 outcome measures immediately after
treatment and at 12 months follow-up. This study corroborates the importance
of treatment expectation before entering a cognitive-behavioral intervention
in patients with chronic musculoskeletal pain. Goosens ME, et al. Clinical
