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.

The number of patients with chronic kidney disease (CKD) is increasing worldwide, and the disease carries a serious physical and psychological burden that creates negative emotions among patients. The negative emotions limits patients’ ability to manage their disease and prevents them from effectively delaying disease progression. In this study, we applied a network analysis to explore the network relationship between negative emotions and self-management in patients with CKD and to investigate the risk or protective effects of different components of negative emotions on self-management. The study was conducted from September 2021 to March 2022 in three tertiary hospitals in China, with data gathered via a convenience sampling method. 360 patients with CKD at stages 1 ~ 3 in the department of nephrology completed the Sociodemographic Questionnaire, Positive Affect and Negative Affect Scale and Chronic Kidney Disease Self-management Instrument. We used R4.1.1 software to estimate the network model and calculate the related indicators. The network showed that among negative emotions “irritated” was negatively correlated with “self-integration”, “problem solving”, “seeking social support” and “adherence to recommended regimen” in self-management. The correlations between “scared” and “self-integration”, “nervous” and “problem solving”, and “ashamed” and “seeking social support” were all positive. The bridge expected influence of “irritated” and “adherence to recommended regimen” were the highest, with values of -0.19 and 0.13, respectively. “Irritated” has a more obvious risk effect on self-management. This study provides an important target for interventions to reduce negative emotions and improve self-management ability in patients with CKD.
