It is more than 40 years since a burst of studies in the late 1960s started what has become a substantial corpus of work, establishing the role of life events in psychiatric disorders (Brown & Birley, 1968; Paykel et al. 1969). Findings depended on advances in methodology. First, came development of a life events questionnaire and a scaling of their stress magnitude (Holmes & Rahe, 1967); then, replacement by more reliable and valid interview methods and better ways of distinguishing major and minor events (Brown & Harris, 1978; Paykel, 1996).
