Randomized Clinical Trial of Pain Psychology/Neuroscience and Written Disclosure for Chronic Pain

This study will recruit adults with chronic back and neck pain. Participants will be adults between the aged of 18 and 75. Participants will be excluded if they have the presence of serious disease or impairment (cancer, systemic infection, serious vision impairment), if there is clear evidence of significant structural damage likely causing their pain (eg, vertebral compression fracture); being considered for interventional spine procedures (eg, steroidal injections) or surgery; leg or arm pain more severe than back or neck pain; if they have been diagnosed with fibromyalgia, rheumatoid arthritis or have active psychosis. Participants will be allowed to engage in this study regardless of current medication use or engagement in other treatment.

Participants who are interested in participating will complete a brief online zoom interview to determine eligibility and will be provided with basic information about the study. Once eligibility has been determined, consent form and, baseline measures will be sent out and completed online.

Participants will be emailed confirming they are still interested in participating. Once they reply, they will complete baseline measures (on-line) and then be randomized 1:1 to the pain psychology and affect neuroscience education intervention or the health behavior intervention. For the pain neuroscience education, participants will complete a 15 to 20-minute on-line exercise that inquires about 5 domains: the degree of central sensitization symptoms, catastrophizing , personality factors, stressors that triggered or exacerbated the pain, and adverse childhood experiences. The health behavior control intervention participants will engage in a 15 to 20-minute on-line exercise examining their health behaviors in five domains: exercise, sleep, diet, hygiene, and social connections.

Once they have completed the first intervention participants will be randomly assigned to the written emotional disclosure task or the healthy behavior-writing task. For the written emotional disclosure task participants will be asked to write for 20 minutes about their very deepest thoughts and feelings about the most traumatic experience of their lives. There will be a 10-minute break and when they return participants will be asked to write again for 20 minutes about how you have come to understand what happened and how you have changed because of the event. The healthy behavior writing task will include writing for 20 minutes a letter to a person of their choosing describing healthy behaviors, a 10 minute break and a second 20 minute writing task describing a time when they performed a healthy behaviors.

Follow-up measures will be administered 5 weeks after the intervention. There will be clinical outcomes assessed that reflect changes in pain severity, pain-related interference and pain catastrophizing. Psychological outcomes that reflect changes in symptoms for depression, anxiety, fatigue and sleep. Finally there will be attitudinal outcomes in stigma around chronic pain and patients' attributions about the role of psychological and brain-based factors in pain and self efficacy.
