Primary Outcomes (1)

  • Global impression of change (PGIC) between groups at end of treatment (Day 28)

    This is a 1-item survey that measures patient perceptions of intervention success. This survey is scored from 1 to 7, where lower scores indicate a better outcome.

    Day 28

Secondary Outcomes (7)

  • Chronic pain severity between groups in the study period (Days 1 - 28)

    Days 1-28

  • Change in pain interference based on the pain interference 4a short form items from the Patient Reported Outcomes Measurement Information System (PROMIS)-29+2 Profile v2.1

    baseline (day 1), day 28

  • Anxiety based on the Patient Reported Outcomes Measurement Information System (PROMIS)-29+2 Profile v2.1

    Days 1-28

  • Sleep disturbance based on the Patient Reported Outcomes Measurement Information System (PROMIS)-29+2 Profile v2.1

    Days 1-28

  • Change in suicidal ideation based on the Negative Suicide Ideation questionnaire (PANSI)
