The role of a broad range of life events, especially those viewed as stressful, in the genesis of somatic illnesses or psychiatric disturbances is a subject of considerable interest. Recently attempts have been made to develop quantitative measures of life events and to explore the relationship between the ‘amount’ of life events and/or stress and illness in a general population (Rahe et al., 1968; Rahe et al., 1970): for example, The Social Readjustment Rating Questionnaire (SRRQ) (Holmes and Rahe, 1967). In the development of this scale a list of 43 life events was presented to a sample of 394 subjects. Marriage was arbitrarily assigned a value of 500, and the subjects were asked to compare the amount of relative readjustment they would anticipate from the other events. Means and item rankings (Masuda and Holmes, 1967) have been reported to be relatively consistent in groups of different age, sex, marital status, education, social class, generation American, religion, race and cultural background (Holmes and Rahe, 1967). These findings have been found reliable with patients on our unit and in a group of medical students (Mendels and Weinstein, 1972). Paykel et al. (1971) performed a study of weightings of a list of life events and obtained weights which were highly significantly correlated for the 14 items that were identical to those found on the SRRQ. They tested a mixed group of psychiatric patients and found that in general those events defined as ‘exits’ were scaled high, whereas events defined as ‘entrances’ had lower values.
