Scale characteristics and mapping accuracy of the US EQ-5D, UK EQ-5D, and SF-6D in patients with rheumatoid arthritis.
To compare the US EQ-5D with the UK EQ-5D and the SF-6D in patients with rheumatoid arthritis (RA). To provide mappings for each of the scales based on clinical variables. ⋯ The US EQ-5D differs from the UK version and from the SF-6D in mean scores and ranges. When determined by mapping, the US EQ-5D has a much lower prediction error than the UK EQ-5D. Simple mapping models that use HAQ and pain have acceptable error rates, although more complex models that include mood scores and individual HAQ items substantially improve predictive accuracy.

To describe symptom patterns and the course for recovery in persons with whiplash-associated disorders (WAD) over 6 months after a car collision, and to investigate associated gender differences. ⋯ Our findings support that the symptom pattern of WAD and the prevalence for many of the symptoms decreased over a 6-month period.

Assessing back pain: does the Oswestry Disability Questionnaire accurately measure function in ankylosing spondylitis?
To determine whether the Oswestry Disability Questionnaire (ODQ) can be used to assess the degree of pain or disability in patients with ankylosing spondylitis (AS). ⋯ The strong correlations between the ODQ and BASFI and BASDAI indicate that it identifies both activity and function domains in AS. This is the first demonstration of a role for this outcome measure in the assessment of patients with AS.
