Mindfulness-Oriented Recovery Enhancement Ameliorates the Impact of Pain on Self-Reported Psychological and Physical Function Among Opioid-Using Chronic Pain Patients
Abstract
Context.
Chronic
pain impacts one-third of the U.S. population, and its effects are
debilitating for individuals and costly to the medical system. Although
opioids are commonly prescribed to address chronic pain, they confer
risk for misuse and addiction, and may not fully restore life function –
particularly with regard to psychosocial factors. Because of the
multiplicity of impacts that chronic pain may have on daily functioning,
broad-spectrum behavioral interventions are needed.
Objectives
The
purpose of this study was to conduct follow-up analyses from a pilot
randomized controlled trial of Mindfulness-Oriented Recovery Enhancement
(MORE) to assess specific effects of MORE on various biopsychosocial
aspects of pain-related impairment.
Methods
Chronic pain patients (N=115;
mean age 48±14 years; 68% female) were randomly assigned to either
eight weeks of MORE or to a support group (SG). Domains of pain-related
functional interference were measured with the Brief Pain Inventory at
pre- and post-treatment, and at a three-month follow-up. Treatment
effects were analyzed with multivariate intention-to-treat models.
Results
MORE
participants reported significantly greater reductions in functional
interference than SG participants at post-treatment across all domains,
including: general activity, mood, walking ability, normal work,
relationships, sleep, and enjoyment of life. These effects were largely
maintained by the three-month follow-up; however, general activity level
and walking ability were no longer significant, indicating differential
long-term effects between physiological and psychological functioning.
Conclusion
Findings
demonstrate preliminary efficacy of MORE as a treatment for
pain-related functional impairments, and suggest that effects may be
more pronounced and durable for aspects of psychological function.
