Psoriasis is a chronic condition requiring sustained outpatient follow-up, patient education, and coordinated nursing care. Effective self-management is essential for supporting individualized patient education, guiding nursing care planning, and evaluating outpatient service outcomes; however, disease-specific tools to assess self-management efficacy are limited in Türkiye. This methodological study aimed to conduct the Turkish cross-cultural adaptation and psychometric evaluation of the Self-Management Efficacy Questionnaire for Patients with Psoriasis (SMEQ-PSO), originally developed by Sun et al. The study included 147 patients with psoriasis vulgaris attending a dermatology outpatient clinic. Content validity was assessed using expert evaluation, while construct validity was examined through exploratory and confirmatory factor analyses. Reliability was evaluated using Cronbach’s alpha, McDonald’s omega, and split-half methods. Among 147 participants, 55.1% were male, with an average age of 45.16 (± 14.83) years. S-CVI/Ave was 0.97. EFA revealed a five-factor structure explaining 70.5% of the variance (KMO = 0.92). CFA showed acceptable model fit (χ²/df = 1.61, RMSEA = 0.07, CFI = 0.92). Cronbach’s α and McDonald’s Omega were both 0.95. The Turkish SMEQ-PSO is a valid and reliable instrument for assessing self-management efficacy among patients with psoriasis. Beyond individual assessment, the scale may support nursing-led care planning, targeted patient education, and evaluation of outpatient service delivery in chronic dermatological care settings.
