A repetition-prediction study of European parasuicide populations: a summary of the first report from part II of the WHO/EURO Multicentre Study on Parasuicide in co-operation with the EC concerted action on attempted suicide.

One of the aims of the European Study on Parasuicide, which was initiated by the Regional Office for the European Region of the World Health Organization in the mid-1980s, was to try to identify social and personal characteristics that are predictive of future suicidal behaviour. A follow-up interview study (the Repetition-Prediction Study) was designed, and to date 1145 first-wave interviews have been conducted at nine research centres, representing seven European countries. The present paper provides an abridged version of the first report from the study. The design and the instrument used (The European Parasuicide Study Interview Schedules, EPSIS I and II) are described. Some basic characteristics of the samples from the various centres, such as sex, age, method of suicide attempt, and history of previous attempts, are presented and compared. The male/female sex ratio ranged from 0.41 to 0.85; the mean age range for men was 33-45 years and that for women was 29-45 years. At all of the centres, self-poisoning was the most frequently employed method. On average, more than 50% of all respondents had attempted suicide at least once previously. The representativeness of the samples is discussed. There were differences between the centres in several respects, and also in some cases the representativeness of the different samples varied. Results obtained from analyses based on pooled data should therefore be treated with caution.
