Résumé	The PsAQoL is a disease-specific patient-reported outcome measure of quality of life impact in psoriatic arthritis (PsA), a chronic inflammatory condition affecting joints and skin. Developed by McKenna and Doherty in 1997, PsAQoL comprises 20 items assessing the multidimensional impact of PsA on physical function, emotional well-being, work productivity, and social participation. PsAQoL captures the patient's lived experience of the disease, complementing clinical disease activity measures (CRP, joint counts) and providing a holistic view of treatment benefit in PsA research and practice.	The DAS28 is a composite measure of rheumatoid arthritis (RA) disease activity, combining joint counts, inflammatory markers, and patient-reported global health. Developed in 1995 by Prevoo and colleagues, it has become the gold standard for monitoring RA activity in clinical trials and practice. It integrates objective clinical signs with laboratory and subjective assessment, providing a single numerical index of disease burden.
