Brief Summary
Approximately 30% of adult Norwegians experience chronic pain, with its prevalence rising across demographics, including children and adolescents Chronic pain contributes to significant personal suffering and substantial societal costs. Traditional treatments - physical, pharmacological, and surgical - as well as psychological interventions, such as cognitive and acceptance-based therapies, demonstrate only minor to modest effects. To address the challenge of rising demand alongside limited treatment options, university hospitals must consistently evaluate and adopt new, potentially effective therapies to meet their societal mission. Pain Reprocessing Therapy (PRT) is one such innovative treatment that has recently demonstrated promising results for a subset of chronic pain patients in a U.S. primary care setting. In this study, the investigators want to assess the effectiveness of PRT on various outcomes in patients with primary chronic pain that has a likely nociplastic pain mechanism, within a Norwegian primary care population. The insights from this study will be important for any prospective implementation of PRT to align with one of the guiding principles of the Norwegian healthcare system: the Best Effective Level of Care (BEON principle). The BEON principle supports the delivery of high-quality, cost-effective healthcare services and is founded on the notion of seamless integration across different levels of care. When competence or resources at the primary healthcare level are insufficient, more patients tend to be referred to higher, specialized, and inherently more costly levels of care, such as secondary and tertiary care. Therefore, if the study can demonstrate that PRT is effective within a Norwegian primary care population, the hypothesize is that its implementation could strengthen both primary and tertiary care in alignment with the BEON principle.

Outcome Measures
Primary Outcomes (1)
Average pain rating in the past 7 days on a numerical rating scale from 0-10 from Patient-Reported Outcomes Measurement Information System - 29 items (PROMIS-29)
Pain intensity average last week assessed through one item. The scale ranges from 0 (no pain) to 10 (worst imaginable pain)
5-week post-treatment assessment (5 weeks after first PRT session; 1 week after final PRT session)
Secondary Outcomes (4)
Physical function measured through PROMIS-29
5-week post-treatment assessment (5 weeks after first PRT session; 1 week after final PRT session) and at 1 year follow-up
Individual goals assessed through Goal Attainment Scaling (GAS)
5-week post-treatment assessment (5 weeks after first PRT session; 1 week after final PRT session) and at 1 year follow-up
Work participation at 1-year follow-up
Assessed through self-report at 5 weeks follow-up and 1 year follow-up
Patient Global Impression of Change
5-week post-treatment assessment (5 weeks after first PRT session; 1 week after final PRT session)
Other Outcomes (3)
Perceived injustice
Baseline, 5 weeks and 1 year follow-up
Pain catastrophizing
Measured at 5 weeks post-treatment and at 1 year follow-up.
Fear of movement or re-injury
Measured 5 weeks post-treatment and at 1 year follow-up.

Interventions
Pain Reprocessing Therapy (PRT) has shown promising results for patients with chronic primary back pain with a nociplastic pain-mechanism. PRT consists of two components. The first is an educational component (E) conducted by a physician. The purpose of the educational component is to reorient the patient's understanding of pain in accordance with the theories of nociplastic pain (false alarm based on negative expectations). The second part consists of a set of specific therapeutic techniques (T) that can be performed by a physician, psychologist, or other trained healthcare personnel. The techniques are easy to learn and have a training framework of 50 hours over a period of 3 months. They are based, among other things, on interoceptive exposure techniques, where the main point is to confront internal sensory experiences that have been interpreted as threatening (and ultimately lead to pain), with a new assurance that they do not signal danger ("false alarm").
Eligibility Criteria
You may qualify if:
- Age between 18 and 70
- On sick leave, or at risk of sick leave
- Pain intensity corresponding to 3 (or more) on the NRS from the PROMIS-29.
- Readiness to change, corresponding to the action stage from the readiness to change model, where they are ready to participate in their own change process
You may not qualify if:
- Structural causes for their pain (rheumatoid arthritis, cancer, etc.),
- Severe psychiatric conditions (ongoing or previous psychotic disorders, suicidality, or severe depression/anxiety/bipolar disorder)
- Illegal substance abuse, or known dependence on benzodiazepines or opioids
- Ongoing litigation or compensation process related to the pain condition
- Ongoing and severe psychosocial stressors (e.g. recent divorce etc.)
