The cognitive behavioral therapy causes an improvement in quality of life in patients with chronic musculoskeletal pain.

UNLABELLED Chronic pain causes functional incapacity and compromises an individual's affective, social, and economic life. OBJECTIVE To study the cognitive behavioral therapy (CBT) effectiveness in a group of patients with chronic pain. METHODS A randomized clinical trial with two parallel groups comprising 93 patients with chronic pain was carried out. Forty-eight patients were submitted to CBT and 45 continued the standard treatment. The visual analogue, hospital anxiety and depression, and quality of life SF-36 scales were applied. Patients were evaluated before and after ten weeks of treatment. RESULTS When the Control Group and CBT were compared, the latter presented reduction of depressive symptoms (p=0.031) and improvement in the domains 'physical limitations' (p=0.012), 'general state of health' (p=0.045), and 'limitations by emotional aspects' (p=0.025). CONCLUSIONS The CBT was effective and it has caused an improvement in more domains of quality of life when compared to the Control Group, after ten weeks of treatment.
