The PCS score was calculated based on physical functioning, role limitations due to physical problems, body pain, and general health perception, while the MCS score was calculated based on role limitations due to emotional problems, social functioning, mental health, and vitality.
The correlation between the calculated CIRAS and MD-HA Qphysical function scores was also found to be low (Pearson correlation coefficient = 0.08, P = 0.17).> -wrap-foot> Dare are from the Brigham and Women's Hospital Rheumatoid Arthritis Sequential Study linked with Medicare claims (2006 to 2010).
Using the RAND method, eight HRQOL dimensions were calculated: general health, physical functioning, emotional role limitations, physical role limitations, social functioning, mental health, bodily pain, and vitality.
Once the assessment is completed, scales summarizing major domains (e.g., depression, cognition, and physical function) are calculated.
The correlation between the calculated CIRAS and MD-HAQ physical function scores was also found to be low (Pearson correlation coefficient = 0.08, P = 0.17).
Pearson correlation coefficient between CIRAS and DAS28-CRP as well as MD-HAQ physical function scores were calculated.
The item scores are aggregated to three subscale scores, pain, stiffness, and physical function, which are calculated as the mean of the item scores in each dimension.
Cronbach's alpha was calculated for "upper limb symptoms" and "physical function" domains as well as for the overall questionnaire score.
Two summary scores can be calculated from information obtained in the 8 domains- Physical Function and Mental Health Summary Scores [42].
Three subscale scores are calculated, pain (0 to 20), stiffness (0 to 8), and physical function (0 to 68).
However, because the focus of these articles was not on the association between pain and physical function, in most cases we had to calculate the association between pain and physical function (SOR) ourselves.
