SYNOPSIS In a survey of a random sample of the general population recent life events, collected and rated for long-term contextual threat according to the methods of Brown & Harris (1978), were also recorded wftere possible on an inventory of life event categories (Tennant & Andrews, 1977). Of the 82.5 % of all events collected which were covered by the inventory, 12of the 67 event categories accounted for 77% of life events with an aetiologicaly significant rating of marked or moderate long-term threat. Where practical and economic constraints oblige research workers to choose the inventory method, a brief list of event categories, such as the List of Threatening Experiences, is recommended in preference to much longer lists.

Continuing research into life events and depression have been fruitful especially those studies assessing the effect of stressors in combination with other aetiological variables such as genetic factors.

SYNOPSISA two-stage psychiatric survey of a random sample of adults aged 18–64 from Camberwell is described. Agency interviewers carried out the first stage (N = 800), using the shorter form of the Present State Examination (PSE). MRC interviewers, using the full PSE, saw a stratified sample of these (N = 310) in the second stage. A second interview was sought with all those of Index of Definition (ID) level 5 and above at the first interview (‘cases’) and with a random sample of those below that level. 20·9% refused or were never available for the first interview. Of the 800 subjects successfully interviewed, 10% refused a further interview and 12·4% of those finally selected for this interview were either unavailable or changed their minds. The MRC data, weighted to represent the whole sample, are used in our analyses. The prevalence of psychiatric disorder as defined in our study was calculated at 6·1% for men and 14·9% for women. Women shared a higher prevalence of disorder in the age-groups 25–34 and 45–54, but in men there was no significant association with age.In contrast to the findings of Brown & Harris (1978), social class did not have a strong association with disorder. Single men had much higher rates than married men, while the reverse was true in women. In both sexes employment was associated with lower rates of disorder. An attempt to explain the high prevalence in women in terms of their role in marriage and child-care was only partly successful.
