[Psychosocial influences in the precipitation of schizophrenia. A study using the AMPD (Association for Methodology and Documentation in Psychiatry) system]. / Les influences psychosociales dans le déclenchement de la schizophrénie. Une étude au moyen du système AMDP.

A group of 49 schizophrenic was compared to 40 non schizophrenic controls to verify the incidence of psychosocial factors and life events (in the 22 items and anamnestic cards of the AMDP) on the onset of mental dysfunction. Regardless of the period (less than 3 months, from 3 months to a year, more than one year before the disorder), couple, family problems, psychic and somatic stress and physical problems are significantly more frequent in control subjects than in schizophrenics.
