Background and introduction to the WHO/EURO Multicentre Study on Parasuicide.

In most European countries, suicidal behavior is a major public health problem and a considerable drain on resources at both the primary and secondary health care levels. Unfortunately, due to cross-cultural differences both in medical treatment of nonfatal suicidal behavior and in research methodologies, it has proved almost impossible to make valid comparisons between countries. It is therefore imperative that international studies based on the same definitions and methodologies be facilitated if we want to extend our knowledge of suicidal behavior and be able to make suggestions for intervention and prevention. The WHO Regional Office for Europe decided to support a collaborative multicenter study, designed to provide a reliable epidemiological picture of parasuicide in Europe. This article provides an introduction to the study.
