Clinical Trial Summary

Severe chronic pain and opioid use disorder (OUD) occur at significantly higher rates in Veterans compared to the general population. Chronic pain often persists despite engagement in opioid agonist treatment (OAT), the first line treatment for OUD. Recent VA guidelines strongly recommend non-pharmacologic treatment for chronic pain, but individuals with OUD are frequently excluded from pain treatment studies. There is a need for evidence-based pain treatments that compliment OAT for Veterans with chronic pain and OUD. In this study, the investigators will determine feasibility and acceptability for a behaviorally focused pain treatment that includes pain education and a pedometer assisted adaptive walking program for Veterans receiving OAT for OUD. Potential treatment outcomes will be repeatedly assessed using a mobile device, and study-provided pedometers. By offering pain treatment within OAT clinical care, the investigators hope to decrease stigma and increase access for Veterans with chronic pain and OUD.

Description:

The proposed study will address the pain treatment knowledge gap in Veterans with opioid use disorder (OUD) by piloting a behaviorally-based walking pain treatment for Veterans with chronic pain and OUD. Steps to Change (S2C) is a pain-focused treatment comprised of weekly 60-minute treatment sessions held over four consecutive weeks within the a Veterans Health Administration opioid agonist treatment (OAT) clinic. To date, no study has evaluated a pedometer-assisted walking program in individuals with chronic pain and OUD engaged in OAT. Topics for S2C include biopsychosocial pain education, pacing activities, benefits of physical activity, and an adaptive walking program derived from Cognitive Behavioral Therapy for chronic pain (CBT-CP) modules. The control will be matched for treatment exposure and attention. Veterans in both conditions will be provided a pedometer to record daily step counts as an objective measure of physical activity. Importantly, pain is a dynamic process that is known to vary over time and context. Veterans in both conditions will complete ecological momentary assessment (EMA) surveys, where behavior is repeatedly sampled using a mobile device. The primary treatment outcome (i.e., pain interference) will be collected using EMA. The use of EMA offers considerable benefits relative to in-clinic measurement including significantly reducing recall bias and substantially improving reliability of measurement. For example, compared to a single rating, a composite of five daily pain ratings over 2 weeks increased reliability from 0.65 to 0.90.55 Importantly, multiple studies have demonstrated that repeatedly asking about pain (e.g., 3 to 12 prompts per day for 2 weeks) does not increase pain reactivity. The study objectives align closely with the description of a Stage IB pilot trial. Stage IB research determines feasibility and pilot testing of an adaptation or refinement of an existing intervention. Walking is a core component of CBT-CP and physical activity has a strong evidence base as a pain treatment for individuals with chronic pain; however, a walking program for chronic pain has not been evaluated in Veterans with chronic pain and OUD receiving OAT. Aim 1 will determine feasibility of study procedures including randomization, retention, fidelity, and proposed study outcomes of S2C and control conditions. Evaluating the feasibility of treatment and best practices for how quickly Veterans can be screened, consented, and randomized to start treatment is a critical step to inform a larger Stage II efficacy trial. In addition, the investigators will evaluate treatment attendance and retention in both S2C and control conditions to determine feasibility as well as discrimination of conditions for fidelity. The investigators will also collect data on mobile phone ownership and compare EMA survey response rates between conditions to inform future efficacy studies. The investigators expect that treatment attendance, retention, and survey responses for S2C will be equal to or superior then control. Aim 2 will establish acceptability of S2C and health education control by assessing intervention credibility and satisfaction at post-treatment. The investigators expect that Veterans in both conditions will report treatment as credible and satisfying. Since S2C is explicitly intended to increase daily step count, credibility of S2C will also be evaluated by expect greater increases (compared to control) in mean daily step count from baseline to post-treatment. Finally, Aim 3 will determine preliminary efficacy for whether S2C, compared to control, reduces pain interference assessed via EMA. Primary endpoint will be at post-treatment, but the investigators will also evaluate durability or sleeper effects on pain interference assessed via EMA at 3- and 6-month follow up.

Eligibility

Inclusion Criteria:

• Meet DSM5 criteria for OUD and receiving stable (i.e., unchanged in 2 weeks) dose of OAT (i.e., buprenorphine or methadone) in VACHS outpatient addiction clinic
• Report high impact or bothersome chronic pain defined by experiencing pain on most days or every day in the past 3 months that limits general activity or enjoyment
• Self-reported ability to walk 1 block
• Access to a mobile phone with active data plan

Exclusion Criteria:

• Untreated major psychiatric disorders (e.g., bipolar disorder, psychotic disorder)

• Currently engaged in CBT for chronic pain treatment
• Planned surgical intervention for pain

• Substance-Related Disorders

Intervention

Behavioral:
• Steps 2 Change (S2C)
Participants assigned to S2C and health education control will be scheduled for 60-minute weekly group sessions held over four consecutive weeks in the outpatient OAT clinic. Session 1 will provide pain education including a discussion the biopsychosocial treatment model for chronic pain. Session 2 and 3 will introduce a progressive walking program with individual goals and weekly step count benchmarks and introduce activity pacing to address pain flare ups caused by cycles of over activity and subsequent sedentary behavior.. Veterans will be expected to increase their average step counts by 10% over their prior week's average starting in Session 2. Session 4 will help develop a treatment plan to continue walking and identify possible barriers to meeting goals.
• Control
The control will be matched for treatment exposure and individual attention. Treatment discussion will explicitly avoid problems associated with MOUD, substance use, and general self-management strategies. Importantly, group will explicitly avoid talking about pain coping skills and setting goals for daily step targets.
