All present psychiatric research is focussed on the symptomatic aspect of depression on people suffering from schizophrenia. Hence, in a recent research we studied the loss problems in the psychic functioning of subjects within a schizophrenia process, instead of studying clinical depression. We questioned the role and functions of loss within an ego having lost his/her limits and the feeling of his/her existence, in a psychic functioning where the limits of the self/non self are uncertain and within efficient or instable narcissist defenses. By loss problems, we mean all situations when a subject has lost an object, or has to renounce it whether it is linked to separation problems with the primary object, the first step of depressive position, melancholia or mourning. So it means to look beyond the purely symptomatologic and phenomenologic aspect of depression of a subject with schizophrenia, to question his/her function at the metapsychological level and to study the diverse psychological processes used by subjects with schizophrenia to face loss problems. We therefore propose to show the articulations and linkages between loss problems and dissociation problems in the psychic functioning of subjects diagnosed as "schizophrenics" (according to CIM10 criteria) through projective tests (Rorschach and T.A.T).
