Learning to Apply Mindfulness to Pain

The investigators will conduct a 3-site 3-arm pragmatic clinical trial (N = 750) to test effectiveness of 2 Mindfulness-Based Interventions (MBIs), Mobile+Group LAMP and Mobile LAMP, compared to usual practice. Effectiveness will be assessed by pain functioning over the 12-month follow-up period using the Brief Pain Inventory (BPI) interference score. The investigators will test the following primary hypotheses: (1) Mobile LAMP will be more effective at improving chronic pain (as measured by change in the BPI interference score over the 12-month follow-up period) compared to usual practice, (2) Mobile+Group LAMP will be more effective at improving chronic pain (as measured by BPI interference score over the 12-month follow-up period) compared to usual practice, and (3) Mobile+Group LAMP will be more effective at improving chronic pain (as measured by BPI interference change over the 12-month follow-up period) compared to Mobile LAMP without the group component. The investigators will test the following secondary hypotheses: (1) Comparison of intervention group with secondary outcomes listed below, and (2) primary and secondary hypotheses comparisons will be confirmed in gender-specific strata. The primary outcome will be measured as change in BPI interference score over the 12-month follow-up period. Secondary outcomes will include patient-reported measures related to pain, comorbid mental health conditions and function, expected mediators of treatment effects, patient satisfaction, and adverse effects and measures captured in electronic health records. These outcomes will be assessed at 10 weeks, 6 months and 12 months. Implementation data will be collected and described, using the guided Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework.
