[Work disability from mental disorders].

Sick leave certifications allow patients to stay away from work without negative consequences. German regulations state that patients can be granted sick leave when duties can no longer be fulfilled or may endanger health status and when there is a causal relationship between illness and disability. Relevant is not the presence of illness but of a disability which interferes with work requirements. In Germany, an average of 4% of workers are on sick leave at any given time, corresponding to about 2 weeks per year and person. The level of sick leave depends not only on the patient's health status but also on social factors. Mental disorders are a major reason for sick leave. Sick leave can have negative effects by fostering chronicity. In 75% of cases, physicians have been found to grant sick leave incorrectly. It must be kept in mind that not illness per se but only disorders of participation justify sick leave.
