Chronic stress experience and burnout syndrome have appreciable influence on health‐related quality of life in patients with psoriasis

BACKGROUND: Psoriasis has a negative impact on health-related quality of life (HRQoL) and may favour mental comorbidity. OBJECTIVE: To investigate the contribution of chronic stress and burnout experience to HRQoL and how mental health influences the efficacy of an inpatient rehabilitation measure in psoriasis patients. METHODS: Eighty-four psoriasis patients taking part in a 3-week inpatient rehabilitation measure participated in the study. Severity of psoriasis was assessed with the Psoriasis Area and Severity Index (PASI) and by patients' self-evaluation at the beginning and end of treatment. The following aspects of mental health were explored using validated questionnaires. Symptoms of chronic stress and burnout experience: Trier Inventory for the Assessment of Chronic Stress (TICS) and Shirom Melamed Burnout Measure (SMBM). Symptoms of depression: depression scale of the Patient Health Questionnaire in the German version (PHQ-D). HRQoL: Dermatology Life Quality Index (DLQI) and Short Form Health Survey-8 (SF-8). RESULTS: Linear regression analyses revealed that chronic stress, burnout experience and perceived symptom severity but not clinician-assessed severity of psoriasis had independent negative effects on HRQoL. Patients who achieved a PASI reduction of <75% at discharge from the rehabilitation measure had lower baseline QoL and showed more symptoms of depression, chronic stress and burnout than patients who achieved a PASI improvement of ≥75. CONCLUSION: Chronic stress and burnout have appreciable influence on HRQoL and may adversely affect treatment success in psoriasis patients. Our data underscore the importance of a multidimensional approach in the management of psoriasis.
