It is a composite index comprising seven domains: tender joint count, swollen joint count, psoriasis activity or extent, a functional index (HAQ), enthesitis and two patient completed visual analogue scores, one for pain and one for global disease activity. If all 7 criteria are met then the patient is deemed to be in very low disease activity.
