AB Objective. To evaluate the sensitivity and specificity of the classification criteria for psoriatic arthritis (PsA) in a South African cohort. Methods. Data from consecutive patients with PsA and other chronic inflammatory arthritides were collected prospectively. Subjects were classified according to the classification criteria. The sensitivity and specificity in each group of patients were compared with a clinical diagnosis made by a rheumatologist. Results. The European Spondylarthropathy Study Group criteria exhibited the lowest sensitivity followed by the Moll and Wright criteria. The sensitivity and specificity of the ClASsification for Psoriatic ARthritis (CASPAR) criteria were 98.4% and 99.7%, respectively. Conclusion. The CASPAR criteria were evaluated in our cohort and they performed well.
