An Evaluation of MBSR and CBT for Veterans With Chronic Pain — IMPROVE  

Pain Clinical Trial

Official title: An Evaluation of MBSR and CBT for Veterans With Chronic Pain

Status Active, not recruiting

Clinical Trial Summary

Approximately fifty percent of Veterans report chronic pain. Management of chronic pain is often compounded by other life problems, including depression and posttraumatic stress disorder. Use of opioids for pain management entails risk of harm, and effective non-pharmacologic approaches to chronic pain management are needed. Mindfulness-Based Stress Reduction (MBSR) and group Cognitive Behavioral Therapy for Chronic Pain (CBT-CP) are programs that teach skills to improve functionality and quality of life for people with chronic pain. However, studies of MBSR and the group form of CBT-CP for chronic pain remain limited. In the proposed trial, MBSR will be compared to CBT-CP and usual care, with assessment of pain interference and other outcomes at 6-month follow-up. If MBSR and group CBT-CP are shown to be effective in improving outcomes, it would support use of these modalities for chronic pain.

Clinical Trial Description

Background: Pain is one of the most common reasons Veterans seek health care. Mental health conditions (including PTSD, anxiety, and depression) are estimated to co-occur for 30-50% of Veterans with chronic pain. Current recommendations for pain management include an integrative approach informed by the biopsychosocial model. It is increasingly recognized that use of opioids for pain management is associated with risk of harm, yet treatment studies of non-pharmacologic approaches remain limited. Mindfulness-Based Stress Reduction (MBSR) and Cognitive Behavioral Therapy for chronic pain (CBT-CP) teach skills intended to enhance functionality and quality of life in the face of chronic pain. The proposed randomized clinical trial will evaluate if MBSR and CBT-CP each result in improvements in pain interference that are superior to usual care. Two hundred twenty-two Veterans with chronic musculoskeletal pain will be randomized to MBSR, CBT-CP or usual care. Measures pertaining to the primary outcome of pain interference will be collected at baseline, at the post-MBSR/CBT-CP time point, and at 6-month follow-up. In addition, measures of pain intensity, depression, and treatment satisfaction will be applied to more fully characterize the impact of MBSR relative to CBT-CP and usual care. Exploratory analyses will assess if outcomes differ for MBSR and CBT-CP, the impact of the interventions on opioid use and indicators of suicidality, and whether Veteran characteristics assessed at baseline function as treatment moderators. Aims: Primary Aim: Assess if MBSR and CBT-CP each result in greater reductions in the pain interference subscale of the Brief Pain Inventory (BPI) as compared to usual care, from baseline to 6 months post-treatment. Secondary Aim: Evaluate if MBSR and CBT-CP are each superior to usual care in producing improvements in pain severity, treatment satisfaction, and depression. Exploratory Aim 1: Evaluate whether outcomes for patients randomized to MBSR and CBT-CP differ for changes in pain interference, pain severity, depression, and treatment satisfaction. Exploratory Aim 2: Evaluate the impact of MBSR and CBT-CP on utilization of opioid analgesics and markers of suicidality.

Exploratory Aim 3: Evaluate moderators of response to MBSR and CBT-CP to lay the groundwork for identifying Veterans more likely to succeed in one or the other treatment. Potential moderators assessed will include: age, gender, baseline depressive symptoms, anxiety sensitivity, and pain catastrophizing.

Design: A three-arm randomized controlled trial comparing MBSR, CBT-CP and usual care. Participants: 222 Veterans at a large urban VA facility with chronic musculoskeletal pain. Interventions: Group MBSR or group CBT-CP, each 8 weeks in duration. Analyses: Mixed models with assess whether MBSR, CBT-CP each produce greater reductions in outcome variables from baseline to follow-up compared to usual care. Implications: If MBSR and CBT-CP are each shown to be superior to usual care for treatment of chronic pain among Veterans, it would support providing MBSR and CBT-CP for this population. ;
