Objective: This study aims to examine the psychological mechanisms of depression in both bariatric surgery candidates and post-bariatric surgery patients, and to explore the roles of resilience and anxiety in these relationships.Methods: 431 bariatric surgery candidates were recruited from a hospital. One month after bariatric surgery, 228 patients continued to participate in the study. Before and one month after the bariatric surgery, they all completed the Insomnia Severity Index (ISI), Connor and Davidson’s Resilience Scale (CD-RISC), Generalized Anxiety Disorder 7-item scale (GAD-7) and Patient Health Questionnaire depression scale (PHQ-9). Mediation model analysis was used to investigate the mediating role of resilience, mediating role of anxiety and the chain mediating role of resilience and anxiety in the relationship between insomnia and depression.Results: Insomnia positively correlated with depression, through the mediating role of resilience, the mediating role of anxiety, as well as the serial mediating effect of resilience and anxiety among bariatric surgery candidates. However, only the direct effect of insomnia on depression and the mediating role of anxiety were found in post-bariatric surgery patients.Conclusion: The findings demonstrate that insomnia leads to an increase in depression among bariatric surgery patients, with resilience and anxiety playing significant mediating roles. It also highlights the need for targeted resilience-enhancing interventions in obese patients who are about to undergo bariatric surgery.
