BACKGROUND: This study aimed to elucidate the symptom-symptom interactions of sleep quality, depression, and anxiety in Chinese nurses and to compare a multimorbidity group, a comorbidity group, and a healthy group via a network model.
METHOD: A total of 7113 Chinese nurses were recruited from sixty hospitals in January 2024, and their sleep quality, anxiety symptoms and depressive symptoms were measured using the Pittsburgh Sleep Quality Index (PSQI), the Self-Rating Anxiety Scale (SAS), and the Self-Rating Depression Scale (SDS), respectively. Central symptoms and bridge symptoms were identified on the basis of centrality indices and bridge centrality indices, respectively. Network stability was examined using the case-dropping procedure.
RESULTS: The prevalence rates of depression, anxiety and poor sleep quality were 40.02 %, 29.03 % and 65.81 %, respectively. The most central symptom was "Depressed affect", followed by "Panic" in the entire sample and the multimorbidity group. The main symptoms in the multidisease group and the healthy group were PSQI 6 ("Daytime dysfunction") and SDS18 ("Hypnotic drugs"). The most common bridge symptom was "Insomnia", followed by "Sleep disturbance", in the entire sample and the three groups. The bootstrap test indicated that the entire network model was stable, and there were network differences in global strength between the multimorbidity group, the comorbidity group, and the healthy group.
CONCLUSION: Comorbidity of depression, anxiety, and poor sleep quality are relatively common among nurses. This study employed network analysis to identify pivotal central symptoms and bridging symptoms (such as "Insomnia" and "Sleep disturbance"), which should be prioritized as key intervention targets. Regular mental health screenings for nurses, with particular attention to high-risk populations, may help alleviate comorbid symptoms and improve sleep quality.
