Brief Summary
Many people in the US suffer from chronic pain. Often times, individuals who have chronic pain also feel depressed, anxious, or hopeless, which can worsen pain. Psychologists, therefore, have developed several treatments to help people with chronic pain. These psychological treatments differ. The most common treatment is Cognitive Behavioral Therapy (CBT) for chronic pain, which helps patients better manage pain through changing thoughts and behaviors. Two newer, less common psychological therapies are Pain Reprocessing Therapy (PRT) and Emotion Awareness and Expression Therapy (EAET). These therapies emphasize that chronic pain is mainly due to plastic processes of over-sensitization in the brain and nervous system, and that psychotherapies can significantly reduce or eliminate pain. Although similar, PRT and EAET stress different aspects of treatment. PRT emphasizes that one's fear of pain and bodily injury maintains the brain's sense of threat, thereby also maintaining the pain response; EAET emphasizes that one's conditioned psychological state of stress and tension maintains a sense of threat, thereby maintaining the pain response. These three treatments have yet to be compared; it is unclear which psychological processes are most important to treating chronic pain. There is growing interest in single-session psychotherapy interventions. Studies have shown that just a single session of CBT or EAET can help individuals reduce their pain. PRT has yet to be condensed to a single-session intervention. This study will compare a single session of CBT, PRT, and EAET with a no-treatment control group to test whether 1) one treatment outperforms the others, and 2) different mechanisms/ approaches matter to chronic pain treatment.

Outcome Measures
Primary Outcomes (4)
Brief Pain Inventory (BPI) - Pain Severity
4-item measure of pain severity over past week (range 0 to 10; higher scores = worse pain severity)
Baseline to 1-week post-treatment and 1-month follow-up
Patient-Reported Outcome Measurement Information System (PROMIS) - Pain Interference - Short Form 8a
8-item measure of pain interference over past week (range1 to 5; higher scores = more pain interference)
Baseline to 1-week post-treatment and 1-month follow-up
Pain Rating Question
1-item pain rating developed by research team asking "Please rate your pain by circling the one number that tells how much pain you have right now". (0 = No pain, 10 = Pain as bad as you can imagine; higher = more pain)
Immediately pre and immediately post-treatment
Symptom Rating Question
1 -item symptom rating developed by research team asking "Please rate your physical symptoms by circling the one number that tells how much physical symptoms you have right now". (0 = no symptoms; 10 = symptoms as bad as you can imagine; higher = more symptoms).
Immediately pre and immediately post-treatment
Secondary Outcomes (22)
Mood Rating Question
Immediately pre and immediately post-treatment
Patient-Reported Outcome Measurement Information System (PROMIS) - Physical Function - Short Form 10a

Interventions
CBT endorses a pain management model and teaches people skills to cope with chronic pain through reframing thoughts and encouraging behavioral change.
PRT advocates a pain treatment model in which pain can be substantially reduced by helping people learn that their pain is brain-based and can be substantially reduced or eliminated by decreasing fear of pain and bodily injury and providing education on the neuroscience of pain.
EAET advocates a pain treatment model in which pain can be substantially reduced by helping people learn that their pain is brain-based and can be substantially reduced or eliminated by decreasing fear of pain and of various emotional/interpersonal problems.
