Overview of the general area
There is a long tradition of the view that emotional stress might act as a precipitating factor in the onset or exacerbation of skin disorders. The close relationship of the skin with psychological functions is reflected in a variety of expressions such as ‘to be red with rage’ or ‘to jump out of one's skin’. In addition, psychoimmunological and psychoendocrinological research has demonstrated that psychological factors significantly affect the course of a variety of medical conditions including dermatological disorders. However, there is no evidence that dermatological disorders are related to specific psychological traits. Rather, that the impact of skin disorders on quality of life indicates that the impairment of appearance associated with visible and sometimes disfiguring dermatological conditions creates significant psychosocial stress.
The relationship between psychological factors and skin disorders is further complicated by the fact that manipulations such as self-injurious skin picking may cause artificial dermatological lesions. Finally, a high proportion of patients report symptoms that are not adequately explained by a dermatological disease or a known pathophysiological mechanism, such as body dysmorphic disorders. The focus of the present paper is on psychological factors related to skin disorders. With respect to somatoform and artificial disorders, the interested reader is referred to other sources (e.g. Stangier & Ehlers, 2000).
Research evidence
Vulnerability to stress
There is evidence from a large number of studies that stressful life events, daily hassles and chronic stressors can significantly affect the manifestation and course of skin disorders (see also ‘Life events and health’ and ‘Stress and health’).
