This study examined sleep quality in 247 patients with psoriatic arthritis and its association with disease activity, functioning, fatigue, and psychological well-being. Poor sleep was common, affecting over 63% of patients, and was strongly linked to fatigue, anxiety, depression, and pain—more so than to inflammatory activity. Emotional and functional factors contributed significantly to poor sleep quality, highlighting the importance of a holistic approach to PsA care.
