INTRODUCTION: The COVID-19 pandemic has an impact on the physical health and mental health of the community, including healthcare workers. Several studies have shown symptoms of depression, anxiety, and sleep disorders in healthcare workers during this pandemic. However, not many studies have examined the resilience of healthcare workers during this pandemic. Resilience is a person's ability to rise and adapt when times are difficult and is considered to have a protective effect on mental problems. PURPOSE: This study aims to determine the correlation between resilience and anxiety in healthcare workers during COVID-19 pandemic. MATERIALS AND METHODS: This research was a cross-sectional study with observational analytic methods. The respondents were healthcare workers at Dr. Soetomo Hospital as the COVID-19 referral hospital in Surabaya, East Java, Indonesia. Data were collected from 10 to 16 June 2020 by distributing online questionnaires through the Google form application. There were three questionnaires used: demographic data, the State-Trait Anxiety Inventory (STAI) questionnaire, and the Connor-Davidson Resilience Scale (CR-RISC) questionnaire. RESULTS: The 227 respondents had filled out the questionnaire online with 33% had high state anxiety and 26.9% had high trait anxiety. The mean score of the respondents' resilience was 69 ± 15.823. The Spearman correlation test showed a significant relationship between anxiety and resilience (p <0.05), both S-Anxiety and T-Anxiety. CONCLUSION: A significant correlation was found between the level of resilience and anxiety experienced by healthcare workers during the COVID-19 pandemic. The lower the resilience, the higher the anxiety experienced.
