Investigation of factors associated with health-related quality of life and psychological distress in vitiligo [Eine Untersuchung von Faktoren, die mit der gesundheitsbezogenen Lebensqualität und der psychologischen Belastung bei Vitiligo verbunden sind]

Abstract

Background and objectives Skin diseases distort the body image with possible negative effects on the quality of life and psychosocial health of patients. While vitiligo does not affect the physical well-being, it may be psychologically distressing. The present study was based on the hypothesis that particular factors might be critical regarding the adjustment to the disease. Patients and Methods We investigated the vitiligo-related quality of life and psychological distress of 216 patients diagnosed with the disease in relation to demographic factors, disease components, and personality traits. For this purpose, we administered the self-completed questionnaires Dermatological Quality of Life Index, General Health Questionnaire, Eysenck Personality Inventory, and Rosenberg Self-Esteem Scale. Results Statistical analysis revealed a significant positive correlation between patients' distress and health-related quality of life. Moreover, the impact of vitiligo on the quality of life was significantly associated with disease variables as well as personality traits and gender. On the other hand, psychological distress was significantly associated with personality traits and gender, but not with disease components. Conclusions Our results indicate that the psychosocial adjustment to the disease is mainly influenced by subjective factors. This observation could imply the need for targeted support interventions in the treatment of vitiligo. © 2015 Deutsche Dermatologische Gesellschaft (DDG). Published by John Wiley & Sons Ltd.
