This study investigated the effect of emotional stability (ES) on insomnia through anxiety in preoperative patients with cataracts. Fifty-four subjects completed a self-questionnaire that included the Insomnia Severity Index (ISI), the International Personality Item Pool (IPIP) for ES, and the Hospital Anxiety and Depression scale (HADS). Pathway analysis was performed to analyze the mediating effects of ES, the anxiety subscale scores of the HADS, and the ISI scores. The low-ES group exhibited an insomnia severity that was significantly higher than that of the high-ES group (p=0.048). According to the pathway analysis, the significant indirect effect of ES on the ISI scores was mediated by the scores on the anxiety subscale of the HADS. Cataract patients with low ES waiting to undergo surgery have a high risk of experiencing insomnia due to anxiety. Before surgery, it is essential to identify patients’ personality characteristics and provide appropriate intervention.
