Aim
how depression could be linked to social factors and stressful life-e­vents in women
Prs
458 women in South London

survey on their daily life and depressive episodes - focus on important biogra­phical details, ie. particular life events or particular diffic­ulties. These events were later rated in severity by indepe­ndent resear­chers.
Result
8% (37) became clinically depressed in the previous year. 33 (nearly 90%) experi­enced an adverse life event or a serious difficulty (e.g. loss of a loved one, abusive relati­ons­hip). Only 30% of the women who did not become depressed suffered from such adversity.
