Abstract
Key advances in life events research included recognition of the need to differentiate events that were independent of disorder; to take the social context of events into account; to assess life events in terms of the long term threat rather than degree of life change; to determine the temporal linkage between life events and onset of psychiatric disorder; to appreciate the importance of long term difficulties as well as acute events; and to examine the role of vulnerability and protective mechanisms in determining individual differences in response to life events. Stress effects in childhood are considered in terms of possible mediating mechanisms; of turning points in life trajectory; of individual differences in response; of difficulties in the concept and measurement of onset of psychiatric disorder; of possible additivity of negative life events; and of the origins of individual differences in exposure to negative life experiences.
