Health-related Quality of Life in Psoriasis: Important Role of Personal Resources

Abstract

Many patients with psoriasis demonstrate psychological disturbances, including decreased health-related quality of life (HRQoL). The aim of this study was to evaluate selected personal resources and HRQoL in 168 in-patients with psoriasis vulgaris. The following questionnaires were used: Skindex-29, General Health Questionnaire, Coping with Skin Disease Scale, Acceptance of Illness Scale, Life Orientation Test, Multidimensional Health Locus of Control Scale and General Self-Efficacy Scale. It was demonstrated that younger patients experienced fewer problems in psychosocial functioning, and that they showed a correlation between worse HRQoL and both external powerful others and external chance domains in locus of health control. Subjective self-evaluation of health correlated with HRQoL irrespective of patient’ age. Coping with stress strategies hopelessness/helplessness and distraction/catastrophization correlated with worse overall HRQoL, whereas fighting spirit strategy correlated with better overall HRQoL. Hopelessness/helplessness coping strategy, somatic symptoms, disease acceptance, psoriasis severity and patient’ age explained 61% of overall HRQoL variance. Psychomedical interventions designed for psoriatic patients should take into account the above variables.
