Good sibling relationships in adulthood are known to be a protective factor for mental health. The present study examined and compared the relationships of siblings with either a healthy brother or sister or one experiencing schizophrenia. In the first phase, we ran a statistical comparison of the two sibling groups on the quality of their sibling relationships (warmth, conflict, and rivalry), emotional distress, and self-esteem. In the second phase, we looked at whether the quality of the sibling relationship modifies the impact of having a brother or sister with schizophrenia on emotional distress and self-esteem. Results showed that sibling relationships in schizophrenia are less warm and are characterized by heightened rivalry and conflict. In addition, analysis revealed a mediating effect of sibling relationship on the emotional distress of siblings with a brother/sister diagnosed with schizophrenia. More needs to be done to enhance the mental health of adults who have a brother or sister with schizophrenia, notably via their sibling relationships.

使用ASRQ-S比较患有或没有精神分裂症的法国成年同胞之间的关系：对情绪困扰的中介作用。

众所周知，成年后良好的兄弟姐妹关系是心理健康的保护因素。本研究检查并比较了兄弟姐妹与健康的兄弟姐妹或患有精神分裂症的人的关系。在第一阶段，我们对两个兄弟姐妹群体的兄弟姐妹关系（温暖，冲突和竞争），情绪困扰和自尊的质量进行了统计比较。在第二阶段，我们研究了同胞关系的质量是否改变了患有精神分裂症的兄弟姐妹对情绪困扰和自尊的影响。结果表明，精神分裂症中的同胞关系不那么热情，其特点是竞争和冲突加剧。此外，分析显示，兄弟姐妹关系对诊断为精神分裂症的兄弟姐妹的兄弟姐妹的情绪困扰具有中介作用。需要做更多的事情来改善患有精神分裂症的兄弟姐妹的成年人的心理健康，特别是通过他们的兄弟姐妹关系。
