Brief summary

The long-term goal of this two-phase project is to reduce chronic pain and co-morbid conditions among Veterans, through scalable, non-pharmacologic evidence-based strategies that are Veteran-Centric, designed to optimize engagement, adherence and sustainability, and are deliverable to large numbers of Veterans.

Detailed description

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.

Interventions

BEHAVIORALMobile+Group LAMP Mindfulness-Based Intervention

The Mobile+Group LAMP Mindfulness-Based Intervention (MBI) condition consists of eight 90-minute weekly group sessions, delivered via secure video-conferencing. The first session is preceded by a 90-minute technical session introducing the video-conference system and other logistics. The program consists of educational and instructional videos presented by a trained mindfulness instructor interspersed with workbook reflections and group discussions, and daily practice exercises that participants do on their own. A trained facilitator (who is not required to be an expert in mindfulness) leads the group. Participants also have access to a mobile app and a study website, with the same educational and instructional videos that are presented in the group sessions, and the accompanying workbook.

BEHAVIORALMobile LAMP Mindfulness-Based Intervention

The Mobile LAMP MBI consists of 8 self-paced, 30- to 60-minute weekly sessions, delivered on a mobile app and available on the study website, with an accompanying workbook. The program consists of educational and instructional videos presented by a trained mindfulness instructor, with workbook reflections and daily practice exercises that participants do on their own (the same content used in Mobile+Group LAMP). Participants also participate in 3 engagement phone calls with a facilitator. The 1st call (45-60 minutes), held at the beginning of the program, includes technical and logistical information on engaging with mobile app, website, and workbook; and discussion of goals, challenges and plans for practice. The 2nd (middle of program) and 3rd call (end of program) are 25-45 minutes long and address technical/logistical issues and discussion of goals, progress, plans for practice and strategies to address challenges.
