Life events and the onset of affective disorder. A longitudinal general population study.

This paper examines the relationship between life events (ascertained by the Bedford College method) and the onset of affective disorder (defined according to the RDC scheme) in a longitudinal general population survey of women. Fall-off in the reporting of minor events is examined and discussed. Event rates, proportions of women challenged by events, and measures of the risk of RDC disorder associated with the experience of particular events are reported. The results based upon data from an initial interview were largely consistent with those based upon follow-up data, and underpinned earlier work. For both data sets, major difficulties were associated with illness onset. Severe dependent events showed stronger effects than severe independent events but both categories were rare. New substantive findings arising from short-term general population event research are unlikely.
