The mean KAP scores were 7.14±2.98 (possible range: 0–12) for knowledge, 52.57±7.07 (possible range: 13–65) for attitude and 62.77±13.24 (possible range: 18–90) for practice. Multivariate analysis indicated that knowledge, attitude, being male, aged 25–30 years and having health insurance were independently associated with proactive practice. Additionally, structural equation modelling revealed that knowledge directly influenced both attitude and practice, while attitude also directly impacted practice (all p<0.001).Conclusions The study found that rosacea patients had inadequate knowledge, a positive attitude and suboptimal practices regarding their condition. It is recommended that comprehensive patient education and support programmes be developed to enhance knowledge, foster positive attitudes and improve practice behaviours among rosacea patients.All data relevant to the study are included in the article or uploaded as supplementary information.
