The prevalence of attempted or completed suicide was studied in the families of a consecutive sample of young suicide victims aged 15-29 years. In 17 of 42 (40%) of the men and 5 of 16 (31%) of the women suicidal behaviour was found to be present in first-degree relatives. Male suicide victims with a family history of suicidal behaviour had an earlier debut of their own suicidal behaviour, longer suicidal processes, and had made more previous suicide attempts. Families in which suicidal behaviour was displayed by the victim's parents or siblings also had more frequent early separations between parent and victim and more substance abuse. Taking into account suicide by a friend or second-degree family member, it was found that 72% of suicide victims had a history of suicidal behaviour in close relationships.
对15至29岁年轻自杀受害者连续样本的家庭中自杀未遂或自杀成功的发生率进行了研究。在42名男性中的17名（40%）以及16名女性中的5名（31%）的一级亲属中发现存在自杀行为。有自杀行为家族史的男性自杀受害者自身自杀行为首次出现的时间更早，自杀过程更长，且之前尝试自杀的次数更多。受害者的父母或兄弟姐妹表现出自杀行为的家庭中，父母与受害者之间早期分离的情况更频繁，且药物滥用情况更多。将朋友或二级家庭成员的自杀情况考虑在内，发现72%的自杀受害者在亲密关系中有自杀行为史。
