Data from 1848 cases of attempted suicide on the files of the Milan University Emergency Psychiatry Ward and 990 suicides recorded by the Milan Legal Medicine Department in the period 1964-1969 were computerised on specially prepared cards, designed to permit objective study of acts of self-destruction in the light of the relations between the subject, his family, and the community. The results point to the importance of extra-subjective factors (loss of cohesion in the family, the way in which parents carry out their respective roles, various environmental factors) as motive forces in attempted suicide.
米兰大学急诊精神科病房档案中的1848例自杀未遂病例以及米兰法医学部在1964年至1969年期间记录的990例自杀案例的数据，被录入到专门制作的卡片上进行计算机处理。这些卡片旨在依据个体与其家庭及社区之间的关系，对自我毁灭行为进行客观研究。结果表明，主观外在因素（家庭凝聚力丧失、父母履行各自角色的方式、各种环境因素）作为自杀未遂的驱动力具有重要意义。
