In this study, we examined the feasibility and added value of including peer informants in a psychological autopsy study of youth suicides. Peer semi-structured interview data from 16 cases were analyzed qualitatively and compared to parent data. Results show that peers added information to parents’ narratives in general and particularly on social relationships, bullying, school experiences, social media, and family relations. Peers also provided additional information on the presence of certain issues (such as social media contagion) as well as on the emotional impact from certain adverse events that seemed to have functioned as precipitating factors. We conclude that including peers in psychological autopsy studies of youth suicides is feasible and of added value but that more research is desirable. The results initially can be used in the design of psychological autopsies so that the maximum amount of information about each suicide will be learned.

在这项研究中，我们研究了在青年自杀心理尸检研究中纳入同伴知情人的可行性和附加值。对来自 16 个案例的同伴半结构化访谈数据进行定性分析并与父数据进行比较。结果表明，同龄人通常在父母的叙述中增加了信息，特别是关于社会关系、欺凌、学校经历、社交媒体和家庭关系的信息。同行还提供了有关某些问题（例如社交媒体传染）的存在以及某些似乎起到促发作用的不良事件的情绪影响的额外信息。我们得出的结论是，将同龄人纳入青年自杀的心理尸检研究是可行的并且具有附加值，但需要更多的研究。
