Abstract

Objective: Current psychological and behavioral therapies for chronic musculoskeletal pain only modestly reduce pain, disability, and distress. These limited effects may be due to the failure of current therapies: a) to help patients learn that their pain is influenced primarily by central nervous system psychological processes; and b) to enhance awareness and expression of emotions related to psychological trauma or conflict.

Methods: We developed and conducted a preliminary, uncontrolled test of a novel psychological attribution and emotional awareness and expression therapy that involves an initial individual consultation followed by 4 group sessions. A series of 72 patients with chronic musculoskeletal pain had the intervention and were assessed at baseline, post-treatment, and 6-month follow-up.

Results: Participation and satisfaction were high and attrition was low. Intent-to-treat analyses found significant improvements in hypothesized change processes: psychological attributions for pain, emotional awareness, emotional approach coping, and alexithymia. Pain, interference, depression, and distress showed large effect size improvements at post-treatment, which were maintained or even enhanced at 6 months. Approximately two-thirds of the patients improved at least 30% in pain and other outcomes, and one-third of the patients improved 70%. Changes in attribution and emotional processes predicted outcomes. Higher baseline depressive symptoms predicted greater improvements, and outcomes were comparable for patients with widespread vs. localized pain.

Conclusion: This novel intervention may lead to greater benefits than available psychological interventions for patients with chronic musculoskeletal pain, but needs controlled testing.
