[Depression and social exclusion]. 
Exclusion is first defined: considered as a constraint, it is distinct from a marginal act, identified as a choice.  The notion of having a depressive attitude is then reviewed according to local variations of expression.  It is examined within a psycho-social-economic perspective and also considering personal identification elements.  The depression of people being excluded is evaluated through 3 criteria: devaluation, cumulative insecurity and indifference.  These criteria allow the evaluation of our mediation: family interviews, family and/or intervening persons working group, basis of educational programs for mental health.
