Abstract

Background: Health literacy (HL) - the ability to seek, understand and utilize health information - is important for good health. Suboptimal HL has been associated with poorer health outcomes in other chronic conditions, although this has not previously been studied in patients with psoriasis.

Objectives: To investigate the HL strengths and weaknesses of a cohort of patients with moderate-to-severe psoriasis. Another aim was to examine possible associations between patients' quality of life, their demographic, clinical and self-management characteristics, and dimensions of HL.

Methods: A cross-sectional study was conducted. Data were collected from a cohort of patients with psoriasis who had received climate helio therapy from 2011 to 2016 (n = 825). HL was assessed by the Health Literacy Questionnaire (HLQ). The association between HL domains, demographic, clinical and self-management variables were analysed using bivariate correlation and a four-step linear multiple regression model.

Results: The scores on all HLQ dimensions indicated lower health literacy than other populations. The linear regression models showed a significant association between HL, quality of life and self-management variables, with higher HL predicting higher quality of life, self-efficacy and psoriasis knowledge. Sex, educational attainment, age and disease severity had less influence on health literacy.

Conclusions: Improving HL may be a useful strategy for reducing disparities in self-management skills for patients with psoriasis. Interventions that aim to reduce disease severity and increase psoriasis knowledge, self-efficacy and quality of life may positively increase HL.
