Abstract

Introduction: Chronic pain increases the risk of prescription opioid misuse or opioid use disorder (OUD). Non-pharmacological treatments are needed to dually address pain and opioid risks. The purpose of the Mobile and Online-Based Interventions to Lessen Pain (MOBILE Relief) study is to compare a one-session, video-based, on-demand digital pain relief skills intervention for chronic pain ('Empowered Relief' (ER); tailored to people at risk for opioid misuse or with opioid misuse/OUD) to a one-session digital health education intervention ('Living Better'; no pain management skills).

Methods And Analysis: MOBILE Relief is an international online randomised controlled clinical trial. Study participants are adults with chronic, non-cancer pain (≥6 months) with daily pain intensity ≥3/10, taking ≥10 morphine equivalent daily dose and score ≥6 on the Current Opioid Misuse Measure. Participants are recruited through clinician referrals and clinic advertisements. Study procedures include electronic eligibility screening, informed consent, automated 1:1 randomisation to the treatment group, baseline measures, receipt of assigned digital treatment and six post-treatment surveys spanning 3 months. Study staff will call participants at baseline and 1-month and 3 months post-treatment to verify the opioid prescription. The main statistical analyses will include analysis of covariance and mixed effects model for repeated measurements regression.

Main Outcomes: Primary outcomes are self-reported pain catastrophising, pain intensity, pain interference, opioid craving and opioid misuse at 1-month and 3 months post-treatment. We will determine the feasibility of ER (≥50% participant engagement, ≥70% treatment appraisal ratings). We hypothesise the ER group will be superior to the Living Better group in the reduction of multiprimary pain outcomes at 1-month post-treatment and opioid outcomes at 1-month and 3 months post-treatment.

Ethics And Dissemination: The study protocol was approved by the Stanford University School of Medicine Institutional Review Board (IRB 61643). We will publish results in peer-reviewed journals; National Institute of Drug Abuse (funder) and MOBILE Relief participants will receive result summaries.
