Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
Potential participants are patients referred to rehabilitation at five different Unicare rehabilitation centers in Norway (Unicare Helsefort, Unicare Coperio, Unicare Hokksund, Unicare Friskvern and Unicare Jeløy) due to long-term pain complaints. Potential participants are referred to outpatient or inpatient rehabilitation or a shorter assessment stay (where the goal is to assess what is the best treatment option for the patient). Referrals to the rehabilitation centers are done by the patients' general practitioner or by specialist healthcare. All referrals are considered at the regional unit for referrals (Regionalt henvisningsmottatak) in mid- or southeast Norway who judge whether they fulfill the criteria for rehabilitation in specialist health care.
