Development and psychometric evaluation of the PMR-Impact Scale: a new patient reported outcome measure for polymyalgia rheumatica
Authors' conclusion
The PMR-IS offers researchers a new way to assess patient-reported outcomes in clinical studies of PMR. It has been developed robustly, with patient input at every stage. It has good construct validity and test-retest reliability.

Primary result
As reported in the abstract
- PMR-Impact Scale (PMR-IS) formed, comprising four domains (symptoms, function, psychological and emotional well-being, steroid side effects)
