Experimental: Single Session Skills-Based Pain Psychology Class
"Empowered Relief (ER)": A single-session skills-based approximately 2-hr group intervention for chronic pain.
Behavioral: "Empowered Relief" (ER)
"Empowered Relief (ER)": A single-session skills-based approximately 2-hr group intervention to treat chronic pain.
Format of intervention: Therapist-delivered PowerPoint presentation with experiential exercises. Experienced senior level psychologist and two (2) additional doctoral level psychologists will conduct the ER sessions.
Content of intervention: ER Participants have the 'ER Relaxation Resource' app (guided relaxation audiofile) loaded on their apple or android electronic device.
Active Comparator: Cognitive Behavioral Therapy (CBT)
8-week Manualized Pain-CBT Group Intervention will be delivered by PhD-level psychotherapists (3 in total).
Behavioral: Cognitive Behavioral Therapy (CBT)
Format of intervention: 8-week Manualized Pain-CBT Group Intervention will be delivered by PhD-level psychotherapists (3 in total). The group is run weekly for 8 consecutive classes. Each class is 2 hours with a midpoint break (16 hours total intervention time).
Content of intervention: The protocol and materials were developed with funding from NIH/NCCAM R01 AT006226 (Dan Cherkin, PI) [1& 2], and include content from a pain-CBT program developed by Drs. Ehde, Dillworth, and Turner .
Participants receive a workbook with homework and a copy of The Pain Survival Guide: How to reclaim your life © 2005 by Turk & Winter  for optional reading.
Active Comparator: Health Education (HE)
The active control treatment arm consists only of Health Education and has no psychological treatment components. It is a 2-hour HE class matched to the single-session psychological experimental arm (ER) on 4 important factors: duration, structure, format and site.
Behavioral: Health Education (HE)
Format of intervention: The HE class will be instructor taught and will involve a PowerPoint presentation and handouts. Two additional providers will be identified and trained to conduct the sessions. Selected instructors will have substantial health education experience.
Content of intervention: HE content will include basic information such as nutrition and interacting with the healthcare system; these relatively 'inert' topics are unlikely to impart any specific effects typically found with a true psychobehavioral intervention.
- Trait Pain Catastrophizing (Trait PC) [ Time Frame: 3 months Post-Treatment ]Change in Trait Pain Catastrophizing (Trait PC) from baseline to 3 months post-treatment across all treatment groups
- Trait PC at 6 months Post-treatment [ Time Frame: 6 months Post-Treatment ]Change in Trait Pain Catastrophizing (Trait PC) from baseline to 6 months post-treatment across all treatment groups
- PROMIS Measures at 3 months Post-treatment [ Time Frame: 3 months Post-Treatment ]Change in score of PROMIS domains for chronic pain - including pain intensity, physical functioning, and emotional functioning - from baseline to post-treatment 3 months across all three treatment groups
- Actigraphy for function and sleep [ Time Frame: Several time frames from baseline to 3 months Post-Treatment ]Change in activity & sleep measures from baseline to post-treatment across all treatment groups
