Behaviour research and therapy
-
A key issue in chronic pain treatment concerns changes necessary for reduced pain-related distress and disability. Acceptance and Commitment Therapy (ACT), a behavior change approach, theorizes several important treatment processes. Increased engagement in valued activities appears highly relevant as previous work has indicated it is related to current and future functioning and to treatment outcomes. ⋯ Overall, slope of change in valued activity was predictive of improvement in psychosocial outcomes at post-treatment, including psychosocial disability, depression, pain anxiety, and discrepancy between values importance and success. Slope was not related to change in pain intensity or physical disability at post-treatment, nor was it related to change in any variable at follow-up. Findings are discussed in relation to the ACT model, in that support was provided in relation to post-treatment improvements for psychosocial variables.
