Abstract: Objective: To investigate the interrelationships between individual symptoms of anxiety and obsessive-compulsive symptoms in patients with anxiety disorders, and to analyze the interactions between these symptom clusters. Methods: A retrospective analysis was performed on inpatients with anxiety disorders at a tertiary psychiatric hospital. Anxiety levels were assessed using the self-rating anxiety scale(SAS), while obsessive-compulsive levels were evaluated via the obsessive-compulsive subscale of the Symptom Checklist-90(SCL-90). Network analysis was employed to characterize the interconnections between anxiety and obsessive-compulsive symptoms. Results: A total of 464 patients with anxiety disorders were included, with a mean age of(46.79±16.57) years. Among them, 284 cases(61.21%) were female and 180 cases(38.79%) were male. Network analysis identified three key bridge symptoms linking anxiety and obsessive-compulsive symptom clusters: "feeling that thoughts are swirling in the mind and cannot be shaken off(L3, bridge strength=2.69)", "feeling more easily nervous or anxious than usual(S1, bridge strength=2.23)", and "feeling that the mind has gone blank(L51, bridge strength=1.79)". The bridge strength stability coefficient was 0.36. Conclusion: As a core and bridge symptom, "feeling that the mind has gone blank(L51)" may play a critical linking role between the obsessive-compulsive and anxious symptom clusters in patients with anxiety disorders. Designating it as a priority intervention target can provide new insights for alleviating both anxiety and obsessive-compulsive symptoms in these patients.
