The MATCH Study

The MATCH Study

Chronic pain is a significant problem affecting millions of Americans. Research has shown that psychological treatments can help people with chronic pain manage their pain and improve their quality of life. Three psychological treatments shown to be effective for chronic pain include Mindfulness-Based Cognitive Therapy (MBCT), Hypnotic Cognitive Therapy (HYP-CT), and Cognitive-Behavioral Therapy (CBT). While research has shown these treatments are helpful for people with chronic pain, the benefits people experience from these types of treatments can vary from person to person. There is little research showing who responds best to which treatments. The purpose of this study is to better understand who benefits most from MBCT, HYP-CT, and CBT. By identifying a way to match people with the type of psychological treatment for pain that would work the best for them based on certain personal characteristics, we aim to improve treatments for people with chronic pain in the future.Participation in study activities includes:• In-Person Baseline Assessments (about 2 hours TOTAL): Cognitive Assessment (about 20 minutes), Relaxation and Hypnotic Exercise (about 20 minutes), Brain Wave Activity (EEG) Assessment (60 minutes), Baseline Questionnaire (about 20 minutes)• 7 Follow-up Assessment Sets (45-60 minutes per set, 5-7 hours TOTAL): These assessments will happen before you start treatment, after the 2nd, 4th, and 6th treatment sessions; at the end of treatment, and 3 and 6 months after treatment ends.• 8 Psychological Treatment Sessions (60 minutes each, 8 hours TOTAL): These individual videoconference treatment sessions will occur on average once per week.If you participate in this study, we will need 16-20 hours of your time over a 9–12-month period.
