Each PsAID-12 item is scored on a 0–10 scale. The PsAID-12 total score ranges from 0 to 10. Thresholds were derived from an ROC analysis in which potential cutoffs were assessed for their ability to correctly classify patients on the DAPSA and PASDAS.

DAPSA, Disease Activity Index for Psoriatic Arthritis; PASDAS, Psoriatic Arthritis Disease Activity Score; PsAID-12, Psoriatic Arthritis Impact of Disease-12; ROC, receiver operating characteristic.
