Suicide is a worldwide public health problem. Evidence from previous studies has confirmed the relationship among anxiety, depression and suicidal ideation. However, the complex psychopathological pathways between anxiety and suicidal ideation and between depression and suicidal ideation require further study.
A total of 505 college students from Shanghai during COVID-19 pandemic were investigated in an online study. Anxiety, depression and suicidal ideation of the participants were investigated. R software was used to construct the anxiety-suicidal ideation and depression-suicidal ideation networks and to evaluate the bridge expected influences.
The anxiety-suicidal ideation network had 28 cross-community edges, the strongest one was A7 "Afraid something will happen"-S7 "Unable to solve personal problem"; A5 "Restlessness" and S3 "Hopelessness and suicide thoughts" had the highest bridge expected influences. The depression-suicidal ideation network had 36 cross-community edges, and the strongest one was D9 "Thoughts of death"-S5 "Unable to accomplish something important"; D9 "Thoughts of death" and S3 "Hopelessness and suicide thoughts" had the highest bridge expected influences.
Intricate psychopathological pathways exist between anxiety and suicidal ideation and between depression and suicidal ideation. "Restlessness", "Thoughts of death" and "Hopelessness and suicide thoughts" are considered targets for suicidal ideation interventions. The present study enriches the theory of symptoms and mental disorders and provides a reliable reference for the intervention practice of suicidal ideation.
自杀是一个全球性的公共卫生问题。以往研究的证据证实了焦虑、抑郁和自杀意念之间的关系。然而，焦虑与自杀意念之间以及抑郁与自杀意念之间复杂的精神病理途径仍需进一步研究。
在一项在线研究中，对新冠疫情期间来自上海的505名大学生进行了调查。对参与者的焦虑、抑郁和自杀意念进行了调查。使用R软件构建焦虑-自杀意念和抑郁-自杀意念网络，并评估桥梁预期影响。
焦虑-自杀意念网络有28条跨社区边，最强的一条是A7“害怕会发生什么事”-S7“无法解决个人问题”；A5“坐立不安”和S3“绝望和自杀念头”具有最高的桥梁预期影响。抑郁-自杀意念网络有36条跨社区边，最强的一条是D9“死亡念头”-S5“无法完成重要的事情”；D9“死亡念头”和S3“绝望和自杀念头”具有最高的桥梁预期影响。
焦虑与自杀意念之间以及抑郁与自杀意念之间存在复杂的精神病理途径。“坐立不安”、“死亡念头”和“绝望和自杀念头”被认为是自杀意念干预的目标。本研究丰富了症状和精神障碍理论，为自杀意念的干预实践提供了可靠的参考。
