Introduction - The French social system offers many kinds of allowances and support (in work, everyday life and social life fields) to persons with disabilities. People with severe mental disorders are often considered as having less access than other disabled persons to the various forms of compensation offered by the national solidarity system. Purpose of research : Our objective was to study, for people with diverse kinds of mental disorders, those who are frequent users of support devoted to disability. Methods - By proceeding to an ascending hierarchical classification from the data of the Disability and Health National survey of 2008-2009 and by studying the characteristics of these groups with regards to the available resources of the disability field we wished to clarify the determinants of recourse. Results - Two groups who very frequently have both various kinds of mental disorders (including mental retardation) and physical disorders have a very high rate of using solidarity support linked to disability. A third group, whose recourse to the field of the disability system is less high without being negligible includes people with different medical and social profiles, having signs of social difficulties and physical troubles which may precede or follow their mental problems instead of belonging to a same complex pattern. Conclusions - This self-reported data survey inevitably comprises approximate data as regards to diagnoses and impairments, but no other survey brings such diversified information and it usefully highlights that people with mental disorders should not be considered has having only mental disorders as long as they use the French disability system.
