Abstract
Objective: To investigate the role of different anger variables in predicting quality of life and mood in multiple sclerosis (MS), while controlling for disease severity. Methods: 78 individuals with MS completed questionnaire measures of anger (Anger Rumination Scale and State/Trait Anger Expression Inventory), mood (Hospital Anxiety and Depression Scale); disease severity (Patient Determined Disease Steps) and quality of life (WHOQoL-BREF). Results: Anger was significantly associated with quality of life (QoL) in MS. Higher levels of experienced anger and lack of control over the experience of anger predicted lower psychological and environmental QoL. Depression levels were also predicted by high levels of experienced anger and lack of control over anger. In contrast, ruminating about anger was the strongest predictor of anxiety levels. Conclusions: The results demonstrate that feelings of anger are strongly associated with QoL in MS, even when disease severity is taken into account. Problems in controlling and ruminating about anger may also contribute to mood disorder in MS.

Summary
Multiple Sclerosis (MS) is a chronic demyelinating disease of the central nervous system that causes various neurological impairments. As well as the health challenges faced by those with MS, the disease is associated with emotional disturbances. Depression, anxiety, anger and irritability are frequently reported in MS patients [1,2,3,4]. People with MS often report feelings of anger and irritation, and anecdotally, this appears to negatively impact their overall quality of life (QoL) and increases feelings of depression and anxiety. MS patients often report reduced QoL compared, to the general population, and patients with other chronic diseases [5]. Few studies have examined the role of anger in QoL and mood disorder in individuals with MS, that is the focus of the current research
