This study sought to assess burnout and its relation to pain, disability, mood and health-related quality of life in a group of patients with chronic whiplash-associated disorders (WAD). Forty-five patients with chronic WAD ([greater than or equal to] 3 months) referred to a multidisciplinary rehabilitation centre were included. A questionnaire covering data on background and lifestyle, the Shirom Melamed Burnout Questionnaire, pain intensity, the Neck Disability Index, the Hospital Anxiety and Depression Scale and the EQ-5D was filled in before the first visit to the clinic. A high proportion of burnout as measured using the Shirom Melamed Burnout Questionnaire was found in the patient group (87%). Burnout correlated moderately with present pain intensity, neck disability, depression and health-related quality of life. The results indicate the possible clinical importance of burnout in relation to chronic WAD and the need for further studies including a larger study population and a longitudinal study design.
