Abstract
OBJECTIVES: Psoriasis is a chronic, immune-mediated illness that primarily affects the skin, nails and joints. This illness may predispose people to mental disorders such as depression and anxiety. This study aims to determine the prevalence of depression and anxiety in patients with psoriasis and their correlation with quality of life and associated factors. METHODS: This cross-sectional study involved 174 patients with psoriasis at the dermatology clinic of Hospital Sultanah Bahiyah, Alor Setar. All patients were instructed to complete four sets of questionnaires relating to: sociodemographic profile, clinical characteristics of illness, the validated Malay version of Hospital Anxiety and Depression Scale (HADS) and the Malay validated version of Dermatology Life Quality Index (DLQI). Data were analysed using a descriptive analysis and correlational and multiple logistic regression analyses. RESULTS: We have found that 8.5% patients had depressive and 16.9% had anxiety symptoms. Multiple logistic regression analysis showed that higher DLQI scores, presence of lower limbs' lesions and dyslipidaemia were associated with depression in the sampled population. CONCLUSION: This study has shown that the cohort with psoriasis exhibited notable symptoms of depression and anxiety. This emphasises the need for the assessment of anxiety and depression among patients with psoriasis as these symptoms predict poor quality of life. Such correlation of psoriasis with anxiety and depression essentially leads to psychological sequelae. Affected psoriasis patients need appropriate intervention. Our study paves the way for further research by involving other underlying constructs such as perceived body image and stigma.
