The incidence of traumatic events during the first ten years of life was investigated in two groups of patients suffering from major affective disorder, as well as in mixed psychiatric patients and in healthy subjects. While there were no significant differences between the two groups of affective patients or between the two control groups, the incidence of subjects who underwent such trauma was significantly higher in depressives, compared with controls. These differences are small and are further reduced if events secondary to psychiatric disturbances of family members are excluded.
