Abstract
ABSTRACT
Background
Psoriasis significantly impacts quality of life (QOL) and quality of sleep (QOS) of patients, yet dermatology assessments often do not evaluate sleep.
Objectives
This cross‐sectional survey study investigates the prevalence of poor QOS, and correlation with QOL in psoriasis patients from Sevilla, Spain.
Methods
Psoriasis patients completed: Short‐form health survey (SF‐36), Pittsburg sleep quality index (PSQI), Dermatology Life Quality Index (DLQI), and physician‐assessed Psoriasis Area and Severity Index (PASI). The survey response rate was 96.15% (100/104). Statistical analysis employed Pearson's correlations, Mann–Whitney
U
, and Kruskal–Wallis tests.
Results
Among the 100 patients (avg age = 49; 52 males), 90% exhibited poor QOS (PSQI > 5), with avg PSQI = 10.34 ± 4.45/21, indicating very poor QOS. The SF‐36 average was 59.57 ± 22.82/100, indicating a nearly normalized average QOL. The average DLQI score was 5.25 ± 5.7/30 indicating a small‐to‐moderate effect on dermatologic QOL, and the average PASI was 2.55 ± 3.51/72 indicating mild disease severity. PSQI negatively correlated with SF‐36 (−0.670,

Conclusions
Psoriasis patients commonly experience poor QOS, impacting QOL. Particularly women, unemployed patients, and those that use medication to sleep were most affected. Sleep duration and vitality/fatigue represent areas for intervention.
