Brief Summary

The goal of this clinical trial is to learn which treatment works better for adults with chronic pain. This study is comparing three treatments: Pain Reprocessing Therapy (PRT), Cognitive Behavioral Therapy (CBT), and usual care (whatever a person is already doing to cope with their pain).

The study's main questions are:

• Does PRT work well for adults with chronic pain?
• Which treatment works better for lowering pain: PRT, CBT, or usual care?

This study will compare PRT, CBT, and usual care to see which is most helpful for lowering pain and helping with other problems that people with chronic pain can have.

Detailed Description

Investigators recently developed a novel psychological treatment, pain reprocessing therapy (PRT). Using a combination of cognitive, exposure-based, and somatic psychotherapy techniques, PRT aims to promote patients' reconceptualization of pain as due to reversible, non-dangerous brain activity rather than peripheral pathology. Critically, PRT aims to reduce or eliminate pain, rather than increasing functioning.

In the first trial of PRT (N = 151), 66% of patients randomized to PRT were pain-free or nearly so at post-treatment, as compared to fewer than 20% of placebo and usual care controls. This trial was conducted in a primarily White, highly-educated population with face-to-face treatment, and how PRT effects would generalize to a more diverse population or to telehealth treatment is not known.

PRT was developed to better address pain intensity and pain-related outcomes compared to leading psychological treatments for pain such as cognitive behavioral therapy (CBT). This study aims to yield preliminary findings on the comparative efficacy of PRT vs. CBT vs. usual care. Developing scalable effective, non-pharmacological chronic pain treatments and testing their efficacy in racial/ethnic minorities is an urgent societal need. Accordingly, this study also tests a remotely-delivered PRT intervention in a diverse patient population.

Aim 1 of this study is to test the feasibility (recruitment & retention) of conducting a randomized clinical trial comparing remotely-delivered PRT with an active comparator, CBT, and usual care and to assess the acceptability (helpfulness, satisfaction, & impact) of PRT in a diverse, lower socioeconomic status (SES) patient population.

Aim 2 of this study is to test the comparative efficacy of PRT vs. CBT and PRT vs. usual care on pain intensity and other pain-related outcomes.

Additional resources became available during the study, allowing an increase in sample size from N = 75 to N = 150 to provide greater statistical power aim 2 (comparative efficacy). No interim analyses were conducted at any point, and investigators remained blind to study outcomes. The decision to expand the sample size was made after careful deliberation with Columbia and Cornell Roybal Center Advisory Committees.

Study Groups

Pain reprocessing therapy (PRT)

PRT has 5 components: 1) education about the origin of pain in the brain, its reversibility, and the pain-fear cycle; 2) reinforcing education using personal biography; 3) "somatic tracking" of pain through mindfulness and reappraisal of pain sensations as non-dangerous; 4) lowering the level of personal threat that may trigger pain sensation; and 5) inducing positive affect in periods of pain. Patients will attend 1 assessment and education telehealth session with a physician followed by 8, 50-minute, therapist-led sessions. Pacing will be flexible, ranging from 5-12 weeks, to increase accessibility. Treatment will be provided by experienced PRT clinicians. All PRT sessions will be remotely-delivered.

Group Type: EXPERIMENTAL

Intervention Type: BEHAVIORAL

A promising new psychotherapy for chronic pain

Cognitive Behavioral Therapy for Chronic Pain (CBT-CP)

CBT-CP, considered the leading psychological treatment for chronic pain, is a structured, time-limited intervention that aims to teach patients how to better manage chronic pain and improve their quality of life. Participants will receive 9, 50-minute sessions of CBT-CP over 5 - 12 weeks. The VA CBT-CP protocol contains an initial orientation involving education and familiarization with the CBT-CP approach to chronic pain. The protocol then includes sessions that focus on topics such as exercise, relaxation, pleasant activities, cognitive coping, and sleep. All CBT-CP sessions will be remotely-delivered.

Group Type: ACTIVE_COMPARATOR

Cognitive Behavioral Therapy for Chronic Pain (CBT-CP)

Intervention Type: BEHAVIORAL

A psychotherapy for chronic pain that has 30+ years of research support.

Usual Care

Participants will be asked to continue whatever they are already doing to care for their back pain. Length of the usual care condition will be 5 weeks, the expected mean completion time of the PRT and CBT arms, and may be adjusted at mid-enrollment to match treatment arm length more closely.

Group Type: ACTIVE_COMPARATOR

Usual care

Intervention Type: OTHER

Participants will be asked to continue to do whatever they are currently doing to manage their pain
