Suicide and attempted suicide are problems which continue to occupy the world-wide attention of both health service administrators and research workers. National statistics of completed suicides have shown an increase in rates among people aged 15-24 years and even among children below the age of 15. Conference discussions were based on working papers relevant to four main WHO categories: community mental health services; mental health of children and young people; alcoholism and drug dependence; professional education and training. The topics specifically included are: (1) Modern Trends; (2) Psychopathology; (3) Social and Cultural Aspects; (4) Risk Factors; (5) Prevention and Intervention; (6) Suicide Prevention Services (and their evaluation); (7) Information Systems; (8) Research; and (9) Training and Education of Suicide Prevention Workers.
