Abstract：
Guided by the ecosystem theory model framework, we aimed to explore the influence of three ecological dimensions (social, family and psychological factors) on suicidal intention in people with severe mental illness (SMI). We hypothesized that three factors influence suicidal intention, and that psychological factors may play a mediating role in the influence of social and family factors on suicidal intention.
We collected 994 patients with SMI aged 18 and above from May 2021 to March 2022 in the Fourth Hospital of Fuzhou City. We used logistic regression to analyse the association between social, family, psychological factors and suicidal intention. Furthermore, we explored the mediating effects among the influencing factors.
Younger male patients with schizophrenia were more likely to have suicidal intention due to psychosocial family factors (p < .05). Social factors (poor interpersonal relations, social retreat, social activities outside the home), family factors (parental functions, activities within the family, family functions), psychological factors (anxiety, depression, interest in the outside world, overt aggression, lack of accountability and planning) were all independent risk factors for suicidal intention in patients. Mediation analysis showed anxiety and depression mediated the role of social and family factors on suicidal intention (p < .05).
Social, family and psychological factors were important risk factors for suicidal intention, with anxiety and depression being partial mediators for suicidal intention. Therefore, interventions that enhance family and social functioning and reduce anxiety and depression may be effective in reducing suicidal intention in SMI.

摘要：
目的：以生态系统理论模型框架为指导，我们旨在探讨三个生态维度(社会，家庭和心理因素）对严重精神疾病（SMI）患者的自杀意愿的影响。我们假设三个因素影响自杀意向，心理因素可能在社会和家庭因素对自杀倾向的影响中起中介作用。
方法：收集福州市第四医院2021年5月至2022年3月18岁及以上SMI患者994例。我们使用逻辑回归分析了社会，家庭,心理因素与自杀倾向。此外，我们探讨了影响因素之间的中介效应。
结果：年轻的男性精神分裂症患者更有可能由于心理社会家庭因素而有自杀意向（p<0.05）。社会因素(人际关系差，社会撤退，在家外的社交活动)，家庭因素(父母功能，家庭中的活动，家庭功能)，心理因素(焦虑，抑郁症,对外界的兴趣,公开的侵略，缺乏责任和计划）都是患者自杀意愿的独立危险因素。中介分析显示，焦虑和抑郁在社会和家庭因素对自杀意愿的影响中起中介作用（p<0.05）。
结论：社会，家庭和心理因素是自杀倾向的重要危险因素,焦虑和抑郁是自杀意图的部分中介。因此,增强家庭和社会功能并减少焦虑和抑郁的干预措施可能有效降低SMI患者的自杀意愿.
