Data will be collected by the Hospital Anxiety and Depression Scale (HADS) in both SQRP-PC and SQRP-SC. HADS is a 14-item self-assessment questionnaire in which 7 items address anxiety and 7 items address depression (subscales; HADS-D - depression and HADS-A - anxiety).

The subscale scores can range from 0 to 21, with lower scores indicating better function.

Data will be collected by the Pain Catastrophizing Scale (PCS) in both SQRP-PC and SQRP-SC. The PCS instructions ask participants to reflect on past painful experiences, and to indicate the degree to which they experienced each of 13 thoughts or feelings when experiencing pain, on 5-point scales with the end points (0) not at all and (4) all the time. The PCS yields a total score and three subscale scores assessing rumination, magnification and helplessness. The PCS total score is computed by summing responses to all 13 items. PCS total scores range from 0 - 52. Higher values indicating higher levels of catastrophizing

Data will be collected by the Multidimensional Pain Inventory Scale Swedish version (MPI-S) in both SQRP-PC and SQRP-SC. The construct "psychosocial consequences" is measured by five subscales (total 22 items) where "pain intensity" is the first. The subscales and the index range from 0-6, with higher scores indicating better function.

The outcome will be calculated as Quality Adjusted Life Years (QALYs) which is a "utility value" that ranges between 1 (perfect health), and 0 = death. The standard treatment will be used as baseline and the calculation is a cost effectiveness calculation. Data on health-related quality of life will be used. Higher values of QALYs represents higher cost effectiveness of the intervention.

The calculation formula is as follows: Years of Life x Utility Value = #QALYs
